520W enough for R9 390?

post #1 of 6
Thread Starter 
Hello guys. I've built my PC a month ago and decided to get a GPU later. Now I'm in the market for a new GPU and I've been watching countless GTX 970 vs 390 threads and decided to go with the R9 390. My power supply is a Seasonic S12II 520W Bronze Edition and I'm not sure If it'll be enough. Im not overclocking anything by the way. Here are the specs:

Intel i5 6600K
ASrock Z170 Extreme4
Crucial Ballistix Sport 2x4 2400mhz
Samsung 850 EVO 120GB SSD
WD 1TB Blue
Fractal Define R5
Seasonic S12II 520W

Should I just got with the GTX 970 or?

Either GPU will work, just get the cheaper one. 500W is enough for any reasonable CPU and any single GPU.

The R9 390 is a little bit cheaper , It's the MSI R9 390 8G. Should I go with that one? Even though many people recommending 600-700W ?

If you like running Furmark 24/7? Yes, you need 600-700W. If you're a normal person who plays games? No, 520W is enough.

Keep in mind though. If a review site is testing a component's power draw by using power drawn from the wall (which is typical), it will be a bit high. That 520W unit isn't 100% efficient at converting AC to DC. It's closer to 85% efficient when maxed out (or something, I'm pulling numbers out of my butt but that's a reasonable number for most PSUs) which means it's pulling 520W / 85% = 612W from the wall! A 300W GPU would show up as a 353W load.

More than enough. Coming from real world experience owning a 290 and 290x. I have 630 watt roswill PSU and it was able to run both in crossfire even with mild overclock.

Alright mate , Thanks! I'll go with the R9 390.
