RX Vega 56 - What PSU should I get?

[Frankieanime158]

I'm considering upgrading to Vega 56 from my RX480. As long as the leaks were correct about it being about 20% better then a 1070 I will. And considering those were pre-launch with dipshit drivers, I only imagine it'll improve about a month or 2 in anyways. My worry though, is power requirements. It says it has a 210w tdp (holy fuck), so I'll probably need to upgrade my PSU.

Right now I have an R5 1600, RX480, and my EVGA 500w power supply is carrying it all just fine. I planned on upgrading regardless of a GPU change, just because I want a modular one now. You think 600w would be okay? Let me know, thanks :]

The liquid 64 can run fine on a 650 and that has a 350W TDP, you're totally fine with a 600W for a 56. Just make sure it has two 8-pin plugs on the end because reference Vega 56 requires 2 8-pins, just like Vega 64.

That really depends on how far you want to push the card, if not at all then you will be fine with what you have, but you will be running way out of the efficient peak which is usually 50% load or so

If you dont do any overclock your PSU is good enough. I dont think Vega will be good overclockers either. Cards AMD produced never overclock well, since the performance gain is small but power draw has a massive jump.

I think Gamers Nexus had a pretty good in-depth review here where he also talks about power draw - remember that he sometimes is referring to the power draw from cables and you need to add the draw from the MOBO. In general, i think you are OK with the existing but if you overclock 650+ seems safer. I have been running a GTX 1060 on a 330W quality PSU with an i5 so I'm normally not advocating upgrading PSU's but I think for overclocking a Vega 56 you need it.
