PSU unit for upgrade questions

Wed Jul 28, 2021 7:43 am

I have been gifted a 3070. So I am planning on getting 5800x to pair with it. My question is I have a corsair 620 watt gold rated power supply. I noticed on 3070 packaging it recommended a 750 watt. I also plan on getting a 240 mm AIO to cool the 5800x. Thank you in advance.

If it's a recent model it should be fine. 3000 series are sometimes "peaky" under load and larger PSUs handle it better, but a good PSU should be fine.

Thank you for confirmation. I figured it maybe Nvidia just being overly cautious l.

The 620W should work fine as long as you aren't trying to drive a bunch of HDDs or do some crazy overclocking. 750W would certainly give you a lot more breathing space though. Modern GPUs only drink tons of power when they are being fully utilized. Ampere is an efficient architecture that pulls significant power when the RTX cores being used hard. RDNA2 is more efficient but it has inferior RT performance. I'm continued to be impressed by my 6900XT's efficiency.
