Hello. I'm mechanical engineer with some electrical experience and I would like to share my opinion on this. I think that the problem is RF frequency noise at higher voltages, not the actual capacity of sp-caps (mtcc) or mlcc ones. Higher rated caps 220-330-470uf have much higher frequency noise, and due to this design (closest possible to gpu core for fast voltage discharge/flow) they have smaller or don't have at all RF filter. Because most crashes happening when clock speed is hitting 2ghz, 300+ watts. And mlcc caps are much more unreliable but faster responding than sp caps, that's why you need combination of both. I think this Evga's 4x 220 (lower noise) + 2(ftw) or 1(xc) is very clever and it will actually work fine. But due to capacitor sizes , I don't think that they will top the performance charts (but they will be reliable and higher tier).
So is there "much" difference between using 4x220 or like the fe 2x220 + 2x470? And in what way would that influence anything?
If you look up pcb back pictures on techpowerup.com it seems a lot are using 470 or 330 and not much using 220.
Maybe there can be another reason you can think if that evga uses 220's maybe they have bigger capacity somewhere else or there power delivery won't need bigger ones or something?
It's probably a non issue but i and some others are a bit querious why most others seems to use bigger ones and sin I have no idea how it really works we just can do one thing and that's ask around :)
Difference is as they state 220/330/470 atc .., voltage charge. Bit you need to look at the whole card, not only this 6 caps. This 6 caps are only first responders to the immediate call for power/ followed by voltage controller to take you to the right power stage/ then vrm's kick in / then voltage is called from psu( delivery). Evga was always using best vrm capacitors, switches, and everything was tested properly. It's just my opinion that because they used 220mtcc, that tells me what they estimated to be optimum for the given chip with whole that new 8nm process and other changes. I'm sure that card will perform excellent. Bit because some other partner card's didn't implement power delivery properly, I think Nvidia will tune down nv boost feature, otherwise it would be a massive recoil on some brands.
Thanks. I got a another answer of someone who also states that maybe they went with the 220 on these spots for faster loading/unloading as well. But he also stated that to know 100% for sure you need someone who knows the whole design. Als also why they choose with this after testing/prototyping.
Anyway it's interesting stuff and I am glad to see so many people with more knowledge are prepared to share some basics. Thanks!
I will trust EVGA in that they choose for this setup for a reason compared to bigger caps.
