As title will a 3070 be ok on a corsair 650w psu?

It can spike up to 400 watts according to the FE review on igorslab (average consumption is way less), so assuming your PSU can cope with the transients (and ideally is not a dual rail model), it will probably be okay with a Ryzen 5 3600.

Running my living room PC on a 3070 with 600W BeQuiet PSU. Zero issues solid as a rock.

Should be no problem if it's a decent 650W (Corsair do have some tat).

yes it's fine 3070's dont use that much power especially if you undervolt it you can shave +50watts power consumption and the card runs cooler with better fps. For example at the moment I'm playing elder scrolls online its only using 62 watts at 4k. If I play a new triple A game like bf2042 it uses around 200w

650w is the recommended psu by Nvidia for a 3070, a 3070ti is 750w, so you should be fine

cheers ended up getting a 3060 in the ned

As long as it's not a Corsair CV or green label CX, you should be fine.

Average yes - but they can draw transient spikes much higher than was generally the case with GPUs in the past - I'm not sure on the exact details as the power monitor on my system only updates at 2Hz so doesn't capture such a short lived event accurately but my 3070 can create some fairly big spikes. Shouldn't be a problem on most systems if you have a quality 600+Watt PSU (nVidia recommends 650Watt but that will probably be with some tolerance for people running all kinds of rubbish) and aren't pushing it too hard with additional hardware.

Are these transient spikes an Nvidia thing or is this just GPUs in general?

There is always a degree of it - the newer generations of GPUs seem worse for it both Ampere and RDNA2 - possibly due to more aggressive power management/gating than previous generations - Ampere seems to have some particularly demanding patterns though.

I’m running a 5950x and 3080 off a Superflower Leadex 3 650W. No issues. Go for it.

AMD example, 6600 XT, sub 180 watt average when gaming, but:

This is why I recommend at least a 750w psu for any new gaming build. Even if it's a budget system with a GTX 1660 etc. It avoids PSU worrys several years down the line if you want to do a huge GPU upgrade.

Wise man , I do the same.

Well ive found a good deal on a strix 3070Ti. That needs 3x 8 pin connections. Not sure my 650W is up to it?

MeatLoaf · 4 Jun 2022 at 19:55

Just to update i got the 3070ti.

First impressions its HUGE. Literally only a few mm between the end of the card and my intake fans. Thats in an air 540 case.

Working so far so good. Ive got a gadget thing and under full load the whole PC is drawing about 420W

Haha, well i did have a 6500XT. Sold some of my model railway stuff and got a 3060. Even then i was in 2 minds over a 3070. Then i saw a 3070ti on marketplace and he offered me a goods deal on my 3060 so the 3070ti only cost me an additional £300.

I have a Corsair SF600 Platinum and 3070 all good.
