RTX 3080 power supply requirements - 850W?

[tacticurn]

What would YOU pick if the choice was between a Corsair HX750 (80+ Plat) and a Seasonic Focus GX-850 (80+ Gold) if the prices were the same? I have a 8700K with a 3080, using it for video editing and gaming after hours. Outervision puts me about here. Used to run with a Tx850 since 2011, and its starting to show its age on the noise level mostly. And nephew has a need for a hand me down. I am asking because there are a couple of deals in town where I can get either of those for around 130 euro incl. VAT. And that is a bargain if you ask me.

The Seasonic Focus, the difference between Platinum and Gold is negligable but the extra 100W might make a difference in stability.

I'm not surprised to see an individual mention Igor (this guy never had an Ampere card and a scope in the first place) make up information out of thin air.

Now with that said out, you could try this:

https://pcpartpicker.com/product/DKw7YJ/phanteks-revolt-pro-850-w-80-gold-certified-fully-modular-atx-power-supply-ph-p850gc

Basically a juiced out Seasonic with the ability to run two PCs and whatnot.

Thanks, but this Phanteks PSU isn't on sale, so it would cost me shy of 50€ extra. What would the juiced out bits get me that makes the extra money worth it compared to the Seasonic Focus GX-850?

get the 850w Focus+

The Focus Plus and Prime Ultra were the units with 30 series problems were they not?

I was under the impression the new Focus and Prime no longer had the issue..

I would get the GX if the price is the same.

 

[X71200]

Not a whole lot much, if you could link to a site you're buying from, there might be some other Focus based units than Seasonic's own.

Check out Super Flower's stuff, they make some good units as well. EVGA rebadges and sells those.

It isn't a Focus Plus, but a Focus GX-850 - I compared them on Seasonic's home page and couldn't see a difference between them. Same efficiency rating so, guess its fine?

ITs from https://www.happii.dk/ - they have Super Flower at a significantly higher price but the EVGA GQ 850 for same price. So the EVGA is an OEM Focus with same quality build but EVGA customer support?

 

[X71200]

The GQ is not too good, EVGA does not use Seasonic as an OEM. As for the GX, I'd suggest buying a more beefy Seasonic than those. Asus makes some Focus Plus units as well, with bigger fans and heatsinks, etc. I'll check the site.

Beefi

Oh, well, then Ill probably NOT get the GQ. I was kind of thinking 850W was beefy enough for the build I am running (Outervision recommends 650W). So that gives me 150+ W headroom. And there seemed to be somewhat a split between 750W being enough and 850W being a bit overkill but w/e in this thread up to now. You disagree with that I sense?

Edit: Added a rather important 'NOT'

 

[X71200]

It all depends on your CPU and whatnot. You might pull about 500W tops in games, then it might be 600 or 400. Don't listen to Extreme Power Supply calculator, do your own calculation by checking your components and how much power it all consumes.

I wouldn't bother with the GQ, it's not worth it. Here is an overkill unit:

Super Flower Leadex Titanium - 850W Strømforsyning - 850 Watt - 140 mm - 80 Plus Titanium certified

1.828,00 kr. Strømforsyning ( intern ), ATX12V 2.2 / EPS12V 2.92, 80 Plus Titanium, 140 mm blæser, aktiv PFC, kabler: 2 x 6 pins & 6 x 8 (6+2) pins til grafikkort / 10 x 5 pins SATA / 4 x 4 pins Molex / 1 x 20+4 pins ATX / 2 x 4+4 pins CPU, fuld modulær & sleeved kabler, 850 watt.

It physically looks like a big PSU though, make sure you have the space.

 

[tacticurn]

Thank you for your help, X71200. But it looks like it is twice the cost, and I have been doing fine on an old clanker of a 80+ Bronze certified Corsair TX850 from 2011 for the last 4 months. I think Ill try to scrooge by with a Gold Plus certified replacement. Unless the GX-850 is much worse than what I have, it would probably run just as stable.

 

[X71200]

You're overpaying:

NZXT C-Series C850 Strømforsyning - 850 Watt - 120 mm - 80 Plus Gold certified

999,00 kr. Strømforsyning ( intern ), ATX12V 2.4 / EPS12V 2.92, 80 Plus Gold, 120 mm blæser <strong>med 0 dB mode teknologi</strong>, aktiv PFC, kabler: 6 x 8 (6+2) pins til grafikkort / 8 x 5 pins SATA / 6 x 4 pins Molex / 1 x 20+4 pins ATX, 2 x 4+4 pins CPU, fuld modulær & tynde sleeved...

Same PSU with digital monitoring.

Alternatively, this is even kind of better:

EVGA SuperNOVA 850 P2 Strømforsyning - 850 Watt - 140 mm - 80 Plus Platinum certified

1.352,00 kr. Strømforsyning ( intern ), ATX12V 2.31 / EPS12V 2.92, 80 Plus Platinum, 140 mm blæser <strong>med ECO Control Fan - blæseren stopper ved lav belastning</strong>, aktiv PFC, kabler: 4 x 8 (6+2) pins & 2 x 6 pins til grafikkort / 10 x 5 pins SATA / 4 x 4 pins Molex / 1 x Floppy / 1 x...

Hi,

 

[tacticurn]

With a fairly normal i7 8700K running at 4,9 GHz when boosting, AIO cooler and nothing fancy outside of the 3080 TUF, I'll go with the 850W Gold solution since it is priced the same.

Hi,
More important would be what size breaker the computer is on and how much other stuff is connected to the same circuit as this machine.

Otherwise yeah I'd do 850w minimum too the psu chart doesn't account for extra ocing ability with delid chips or specialized cooling like chiller or just taking advantage of seasonal cold weather cooling.

wait what?
you're saying igor made up his 3080 stats or some individual? what individual anyway

Igor never had an Ampere GPU. The whole capacitor thing was made up without actual evidence in the first place.

Its a modern housing with 13A rated at 240V for the breaker group my pc is on, and it shares it with the normal fixtures for lights etc. of half the appartment. Kitchen hardware is on third group with 16A. I think the power we got is very stable, and clean.

 

[NesteaZen]

@X71200 who's making this claim?

 

[jboydgolfer]

It isn't a Focus Plus, but a Focus GX-850 - I compared them on Seasonic's home page and couldn't see a difference between them. Same efficiency rating so, guess its fine?

its a focus + with a different name.

The Focus Plus and Prime Ultra were the units with 30 series problems were they not?

the problem with the RTX 3 series isnt the PSU, it is that they draw massive power at peak usage in a spike.
the issue is reported with users using many different PSU's from many different OEM PSU makers.
i replaced my focus+ with an identical higher wattage focus+ & it fixed the issue.

 

[mouacyk]

Watercooled 3080 here running fine with Seasonic X-850.

yea, my Over voltage protection shutdowns were with the 3090, on a focus+ 750W. the way i looked at it, i didnt want to order a 850W for $180 & find it didnt cut the power needs, so i just spent $240 for the 1000W version , i figured better safe than sorry.

the beauty is when switching the PSU's, all i had to do was pull the box & the PCI cables, i reused all the other cables from the 750W with the 1000w. as easy an upgrade as installing a new RAM stick almost

i spoke with nvidia , & showed them all the people posting in their own forums about the same issue, how Power supplies that are more than capable based on Nvidias own specs, arent cutting it with real world use of the RTX3 series cards. this is from their own Spec's page.

350W
750W PSU recommendation. so when a guy owns a 750W Power supply from one of the better PSU makers, he'd be understandably surprised when it isnt capable of powering previously mentioned 3090's/3080's
