Computer parts can smell fear. If you can easily replace it, it won't break easily. But if your budget is tight you stare at it wrong and it breaks.
Facts T_T
Somehow true
When I built my rig I made a bunch of stupid mistakes because "whatever I can buy a new one, time to learn"
Despite making every mistake in the book, I now have a functional pc. Idk how I didn't snap the motherboard when I tried tightening it down with 4 standoffs instead of the 3 that it required
Yeah I remembered back then when I was young and broke. I just cleaned my PC, afterwards the contact points on the ram and GPU got scratched and it wouldn't work anymore.
Now that if anything broke I could replace it, even if I bent my cooler shroud, dinged my cpu, and scraped some of the contact points of my GPU they're still all working. Because my PC can't smell my fear anymore. 🤣
@hill2hell
The only time I was fearful during my build was putting down the CPU retention lever because nobody told me how much force it requires
When the plastic cover flew off I nearly shit myself 💀
It's supposed to do that to make sure there's enough pressure on the chip to keep it in place. You should also keep those just incase you wanna resell your mobo it's for extra protection.
Most capacitors on pcbs are 'decoupling' capacitors which basically just filter noise and counter the inducance of the traces but do not actually contribute to the function of the circuit. They can be removed and your circuit can work but it opens a small chance that weird things will happen when the circuit is exposed to electrical noise like radio frequencies, dc power supplies, and sparks
Not to mention that it’s only in 2D mode so the vast majority of that chip is sleeping
Your comment should be higher up!
Exactly this...
Yeps , as an electrical engineer i approve
This is the right answer. Should be pinned.
It's an EVGA, of course it would run

Put it under load and see if it’s still functioning
It will, this guy is removing smoothing capacitors… they basically reduce the ripple in the Electrical signals all across the board… you affecting the long term, the core is likely to die quicker without clean voltages
@@cerealtech4138 it’s likely to crash under load without clean voltage too, you’ll either have to down clock it or risk instability
True, without the capacitors, it won't be able to keep the power surges and temps stable and then the fun will begin!!
@@djmystery7235 true, undervolting via msi seems the only viable option here
even an arduino can't run without a good decoupling cap @@cerealtech4138
Most of those are just for smoothing power input to the VRM and other delicate board components. If your power supply is good it'll be able to keep on trucking for quite a while, though you are putting more stress on those components. If you wanna brick something you need to start looking at the larger caps under the fan housing.
No they are not for smoothing. They are for supply decoupling which is the removal of spikes containing high frequency components.
Smoothing and decoupling are two different applications.
Smoothing is what you do on the output of a linear power supply to take the DC signal containing the 120Hz signal which is present as a consequence of it being full wave rectified, and smoothing out that ripple.
You are filling in the gaps between the crests on each cycle, flattening out the ripple.
You are not dealing with anything above 120Hz (on a 60Hz mains supply).
It's quite a different application to supply decoupling of digital logic circuits.
Yeah so just filtering guys
The small ones behind the core
@@deang5622seems a bit pedantic. Goal of both is to reduce voltage fluctuations
@@danielsnyder656 It is not pedantic. It is right.
Smoothing and decoupling are different applications.
You don't refer to smoothing caps in PSU's as decoupling caps.
You don't refer to supply decoupling caps in digital logic circuits as smoothing caps.
You sound as if you don't have much experience in electronics.
These are accepted terms that have been in use in electronics for at least 40 years.

those are bypass capaictors which act as filters for potential noise in the circuit and are not necessary as they are usually connected to ground
Only on one end of each . Table legs are also connected to ground, but remove too many and the table falls over . To stress things run some lopsided loads that vibrate power drain at different caps . So maybe have one of the CUDA cores zigzag quickly at max frequency, with the others idle .
They *ARE* necessary.
As the power consumption of the chip increases and more of the logic comes into operation and starts to switch between logic levels, more high frequency noise will be imparted on to the various power lines feeding the chip.
If those capacitors are not present, the chip will malfunction.
What you see here is the graphics card in 2D mode, not rendering any 3D graphics at all, which means most of the logic on the chip is not being used, that logic is _not_ switching, and therefore at the present time those capacitors are not essential to the operation of the chip.
Put it into 3D mode and have it rendering large quantities of 3D polygons and texture maps and the situation will change.
@@deang5622 no
@@deang5622 They may not be necessary. A lot of these complex boards are created from modularized pieces of larger pre-existing designs connected and overlayed together. Each piece has a known set of characteristics which speeds up the design cycle.
Most importantly, not every component in layered designs is required in the end product. As long as it passes SPICE analysis, it's good to go to internal testing. The cost of a few dozen extra pick-and-place motions outweighs the cost of additional design/analysis to remove the components safely.
@@deang5622 Oh, and he also ran a benchmark with these removed, in 3D, and it worked fine. Again, very likely to be extraneous due to the design flow.

Making the mother of all CAPACITORS JACK can't fret over every cpu
Caps are mostly for high frequency noise mitigation. No noise, no problem.🎉
I think it'll work like most capacitors I've seen in a circuit is always mounted parrallel on a circuit cuz they just eliminate electronic noise and also keep voltages up but right now im just waiting for him to pick out one single coupling capacitor that is mounted in series and the whole thing might just drop ded 😂
"Let's fuck up this EVGA museum art piece"
Have you tried running games on it? Idle power requirements is different compared to gaming power requirements.
He runs a benchmark everytime
"Some how its still running"
Thats like half my interaction with tech.
It doesn't require all of them for the card to function. It requires a lot of them for stability. A capacitor's secondary function is to get rid of excess "noise" in the circuit. It's what also allows for tighter timing and higher clock speeds when overclocking, as well as longevity of the card.
Bros purposely tryna break it whilst am tryna keep mine alive but it’s still dying
Borrow those capacitors from this guy

lol he will probably give it away to someone and that person probably ontt know how to fix i t lol
at this point the only thing left will be the die and it will perform better
Gpu: “I didn’t hear no bell”
the gpu is like thought I needed those cap's you thought wrong dude seriously🤣🤣🤣
Those are there to ensure stable function, in case of glitches in supply voltage. Try stressing the card to max, you will then see the difference.
I was looking for a comment that actually explained it so thanks
Some people say _it’s like pulling teeth_
Others say *it’s like pulling capacitors*
Give it a stress test now, see if that breaks it
Hardware engineer here, this is going to be a long comment and there's so much more to talk about that doesn't fit here.
Decoupling and PDN optimization is honestly a really fascinating part of hardware design that rarely gets too much attention. Here I can almost guarantee the layout engineer just followed the guidelines suggested by the manufacturer when specifying all those caps though. There's a good chance they just copied the layout from the reference design exactly. There's nothing wrong with with that of course. It's certainly the easiest way to quickly design a product that you have confidence will work. Usually the manufacturer of an IC is assuming something like a 4 layer stack-up and 8.4mil dielectrics without any significant capacitance on the board other than what they specify though.
A lot changes when it comes to decoupling once you start using very thin dielectrics like those in high layer count boards, and these are high layer count boards. Minimum routing requirements for a GPU usually necessitate 8-10 layers. With newer hardware like the 3080 and 3090 and GDDR6X Nvidia's minimum routing requirements actually require a 12 layer pcb with back drilling.
With the extremely thin dielectrics needed to make those stackups the interplanar capacitance increases and the series inductance associated with fields propagating between the planes goes down. The fields can propagate increasingly far between the planes before the impedance of that path starts to be comparable with the impedance associated with the leads and vias of a surface mount capacitor intended for decoupling. With thin dielectrics the planar capacitance is really what provides most of the energy at ps timescales, not the capacitors. And on timescales where the extra capacitance is necessary the fields have propagated far enough that those decoupling caps can be some distance away. The classic technique of trying to crowd a bunch of caps as closely as possible around an IC stops being necessary. So it's not all that surprising that you can remove a bunch of decoupling caps on a high layer count board like this when most of those caps were just copied from a reference design.
A lot of this hardware can also fail more gracefully than you might expect. PCIe for example will fallback from 16x to 8x or 4x operation if it's unable to establish communication across all the differential data lines. DDR memory of all families has some form of error correction and if a frame fails error correction it will attempt to resend the data again and again until it succeeds. So the effect of a high bit error rate isn't usually for everything to stop immediately but generally more of a slowdown and gradual loss of performance.
IC Reference Boards and people copying these references on their own layerstack :D
Today I learned about planar capacitance in vias, very cool, thank you for the explanation!!!
I already kind of understood why you can get away with removing some capacitors, but your explanation was really informative. Thanks for your time and comment!
this guy engineers.
brain boom
GPUs were invented by the capacitor industry to sell more capacitors
GPU equivalent of scooping out more and more of someone's brains and wondering how they are still alive lol
"It works!"
**shits itself after 2 seconds of Minecraft**
"It worked!"
Those resistors are mainly to control spikes for example when power is getting low and current gets high to stabilize it. So it’s a pretty specific fallback.
Those are capacitors... Also "power" is current * voltage so the only way power can go low while current is getting high is if voltage is getting lower than current.
In short... I'm not convinced you know what you are talking about.
@@Segphalt Maybe, if they are capacitors, they still provide fallback for when spikes happen, just on a different level.
However, your last sentence is disrespectful and shows me in short, that you are in fact, a sad person :)
Most of those are put in for EMI control.

[Edit: this is my most liked comment thank you guys
I don't understand
Capacitors have power efficiency and stops voltage spikes
@@TOTALLY_A_CAT_PERSONdoubt that is the result. Capacitors also act as a short term power storage and yes having them can smoothen out voltage. However this could just lead to the GPU power throttling due to not getting a steady voltage or the GPU getting fried due to the power spikes. I highly doubt it would have a visible difference on the power consumption.

@@ilbufalantdellefigurine4488 watch cody's lab playing with kilos of mecury
Those caps are for removing noise in the voltage regulator.
Those caps are parallel to the main electrolytic capacitors and compared to them their values are much much lower like 1% of the main electrolytic ones. If you try to remove the electrolytic ones, the gpu won't work anymore. If you have removed the electrolytic ones before the polymer ones, which you have desoldered, It wouldn't work with only the polymer caps.
Bro must have connected hdmi to motherboard 💀
GPU: don't you know... IM STILL STANDING
Reminds me of when I had an electronics kit as a kid, and had to pull apart the old project to make the next one. There was a surprising percentage of components I could remove before the AM radio I built stopped working. Somewhere around 30%-50%.
Sooner or later, he's gonna tear off the big capacitors inside of the GPU 💀💀💀
Take ¼ of the capasitors and see if the gpu still works (Or give it to me, I need a gou 😅)
Most capacitors are there for redundancy as they are running parallel. If one fails, another carries over. You’re basically just chipping away until you can make some fail by them not being there in order to have a failure on the card
Those are filter capacitors that's why it's still running
The robot overlords will remember this.
Damn, this is almost as good as 'Ow My Balls'

This is like taking the anti-hammer valve off of your pipes and being amazed water still flows through them.
We put capacitors in basically each trace where a cpu or microcontroller is involved. Helps with the emc tests. Doesn't necessarily have to be there to work under normal conditions.
Takes off every part and proceeds to plug into air: still works
There's an old story from the early days of television, when components were absurdly expensive and companies were competing to reduce costs. Supposedly, the lead engineer would take a pair of pliers and remove components randomly until the TV stopped working. Any component that wasn't necessary was removed from the future design!
Capacitors are for filtering, energy storage, bypass, and decoupling. So it should be fine as long as it's not under high load.

Capacitors are mostly used for filtering purposes, as they are connected in parallel, it won't affect the working of the device if being used properly under controlled circumstances.
Maybe that was the Easter egg the designer wanted us to find out.
Capacitors mostly used for filtering.
it prevents high voltage spikes and voltage fluctuation , so the component can last longer.
This guy reinvented "Munzing". Reducing production cost by removing capacitors until a device doesn't work anymore
These are CAPACITORS at the end of the day.
That computer is going to die from the mechanical version of asphyxiation
GPU: Please.. spare me..
Capacitors in DC circuits are almost always for voltage stabilization, so they can be removed but it won't handle changing loads well.

"Ive already told you the bombs locations and defusal codes, what more do you want?!"
"Your soul"
As soon as you put it under load that GPU is gonna have a bad day
If I remember correctly from my electronic design courses, 50% of caps are bypass capacitors, meaning they are there for when the voltage level does funky stuff. But most computers nowadays have a very nice voltage level from the power supply.
RIP EVGA GPUs. They were the best board partner of them all.
After some point this gpu will just go boom.
Bro's doing Yamori type torture on that GPU
This is like tearing out your nerves one by one
They are just filter caps. They are in there to smooth out any voltage spikes and dips, and reduce ringing, but it takes a lot for those to become a problem in most situations anyway.
The capacitors are to hold the GPU bios, kinda like the CMOS battery on the mobo. It just resets to defaults when it doesn't stay charged
The capacitors function is to regulate the voltages coming from the power supply but if you have a really good quality power supply usually it has more than enough that’s why it’s working fine
Not under load is why.
Run games on it and start doing that.
Many capacitors are for regulating voltage spikes. Allowing for cleaner power. So its not like youre preventing power rather just causing spikes in voltage somewhere
Meanwhile when i accidentally rip of one of those gpu instantly dies
They’re all decoupling capacitors to reduce noise of certain signals. All of those capacitors are probably hooked up to the return layer on the PCB and not affecting the connection of the signals. So yeah, the card will still work but if you look at the signals with an oscilloscope, you will find a lot of noise.
Those are mostly there for stability. If one of the components or area of the chip suddenly takes more current it can cause the voltage to drop. The capasator is there to resist the drop.
They filter caps used to clean up the power sign wave so it's nice and clean which gives it stability you will find the more caps you remove the less stable it will become!! There are a handful of 100% necessary to function at all but the majority are used for power filtering for the GPU it self and memory stability as well. If you put it under 100% heavy loads and cycle though the different features it will fail and crash the system or create artifacts on screen.. so really it will seem ok when you plug in and boot but as soon as it's under load or trying to use a feature that has become unstable it will crash.. so thinking "why do I need to pay for parts it doesn't need" is silly because it does need them all to be 100% stable in all conditions and use cases..
Bruh this guy never runs out of Ideas
I'd love to see it under a stress test. My guess is if there's a sudden demand for power the GPU will have a greater chance of running into stability issues especially as you remove more and more capacitors.
Looks like decoupling caps for the DRAM. The PCB has capacitance itself, and of course power converters regulate the power rails to tight levels. Not required, but it's a really scary world when your capacitance becomes so low. You get much higher voltage swings (at the power converter frequency) and become susceptible to a bunch of noise sources.
cappacitors only deal with voltage stabalizing and minor power storage, so removing capacitors generally does not effect the performance of something in any noticable way unless your incoming power to the gpu is unstable, the real danger is shorting one of the capacitors/contacts for the capacitors as then it will very likely stop working
Death by a thousand cuts: tech edition
That GPU owned money to the cartel
That gpu is more expensive than my whole pc lmao
I always knew capacitors were a conspiracy
I like the part where you explained how it still works, and also why you’re doing it lmao
someone needs a crash course in electronics
Those caps are there only to smooth out any eventual interference so you may not notice they're gone under ideal circumstances
Keep in mind that capacitors are literally a break in the circuit - just the empty solder pads separated by air have some capacitance. If they’re mainly there to smooth out jittery signals, then they probably are spending most of their time doing basically nothing.
Gpu is the main protagonist. Keep going and when it gets desperate enough, youll unlock its full potential and itll transform
I do board repairs and commonly find that most capacitors are unnecessary. I often don't replace them because I can tell they're shorted and I dont have a schematic to tell me what to replace it with
As much as i want to see this graphics card make it, i also want to see if it survives a stress test like that. My assumption is hell no but i don’t want the series to end yet im INTRIGUED
