So i been wanting to buy a rx 5700xt to upgrade from my gtx 1060 6gb. Problem is i got a 400w psu. Its a 80+ Gold from BeQuiet. Going by pc part picker the worst case scenario is that it might draw around 395watts which is kinda uncomfortable for me. I know thats unlikely seeing as everything would need to be pinned 100% but still its not impossible. Just wondering if i should upgrade my psu or whether or not it will be ok as i can image "normal" gaming use will have it more around the 330watt total system draw. Tried those calculators but they were saying anything from 400-700watt psu's so just need a more exact answer.

R5 2600 stock speed
16gb 3000mhz ram
Gigabyte b450 ds3h mobo
500gb sata ssd
Psu is a BeQuiet pure power 11 400w CM

Also, not too worried about leaving headroom as long as i got like 10-15% im fine
Thanks in advance for any help

System Requirement

Recommended 650 Watt Power Supply (Minimum 600 Watt Power Supply).

2 x 8-pin Power Connector.
That is just one option, and a heavy duty one at that. Specs for a standard/reference 5700XT are 225W with one 8-pin and one 6-pin connector.

Even the 400W offers dual 6+2 PCIe connectors.

Those inflated figures are for liability purposes. They have no idea how much power the rest of the components in a given system will require, so they overestimate. If you come back and say your 400-500W power supply melted because of their GPU, they can point at their 600W recommendation.

And I can always have an overclocked Threadripper CPU pumping 400W on its own and melt it that way.

Can only find reviews for the 500W, 600W, and 700W models. They look pretty good, so might be okay. Worst case you hit the upper limit and the supply shuts down.

I say try it out, but consider a replacement in the near future. You can always re-purpose that 400W supply for something else later.

I got a Corsair VS550 laying in my old gaming rig so if the 400 ain't enough i'll just swap them over. Would prefer to keep the BeQuiet cause it has nicer cables an is semi modular but if i can't then the 550 will suffice until an upgrade arrives. Thanks for the awesome help btw mate
