is my psu enough for a 3080?

weaselbee

I am looking at getting a 10gb 3080, and would like to know if my psu could power it

Specs:

CPU: 12700k with e-cores off

mobo: aero g ddr4

ram: 2x16gb

psu:pk650d

the 3080 I would want has 2 8-pins, so theoretically a maximum draw of 375w

my CPU draws about 150w in Cinebench r23, so the maths would seem to suggest it is barely possible, but what do you think?

could it damage the gpu or other components?

Honestly it would not but it could so its better to spend a couple of extra bucks and go for a more well known gpu brand like corsair, seasonic,bequiet etc. Btw go modular or semi modular.

Not that likely. But don't be surprised if it just shuts down under load, as the transients from the 3080 are quite hard on the PSU. If it does work, expect the PSU to produce coil whine.

already got the psu, and only using at 1080p for now, so might just undervolt cpu and gpu until I can get a better psu

how much is the 3080? The 10gb doesnt exactly have a lot of vram and it is gonna show that sooner rather than later.

 

Either way no 650w psu cept some stupid high end platinums have been able to handle a 3080

was meaning to ask about that, is a 10gb 3080 enough for the next few years? I mean it was the 2nd highest card nvidia sold until relatively recently.  I would only go up to 1440p, and may stay at 1080p

I could probably get a 6800xt for about the same price, but that doesn't have dlss, would it be a better buy?

from what I can find on the internet, at 1440p, the 3080 only gets near 10gb usage on a handful of games with rtx on

Do you need dlss?  Are you going to use applications that require dlss?

I imagine that most new games will have dlss, and in a few years I expect dlss will be required for high graphics at a reasonable fps

answer is simply no, you need a high quality 850w psu for a 3080 minimum... its not even just power draw, its also transient power spikes which the 3000 series is infamous for.

 

sure, you can try,  but don't be surprised if components fail, windows corrupts, etc, etc.

oh undervolt... i think you mean power limit?

 

for record: my 3070 uses *more* power with a very basic undervolt, cause it runs cooler and clocks higher... that's just how Nvidia boost works.

 

but with a power limit of say 50%, op might get away with it for some time, yeah.

I've got a 4070 super and a 7600x on a 550w, seems to be fine so far

cant you just combine both undervolt + power limit?
