Is my PSU enough for R9 390?

[Thinker_145]

Here are my detailed specs.

Core i7 6700k
ASUS Z170-K
16GB DDR4
1 SSD
1 HDD
Xonar Sound Card
CM HAF 922 Case

My PSU is a 5 year old Corsair GS600. I am currently running an AMD 7850 2GB.

I will not be overclocking the R9 390.

Yes, it's easily enough. I used a 520W Corsair on a way more power hungry CPU (i7 860 @ 3.9Ghz) with a ~280W GPU (GTX470 @ 760mhz). You are fine.

Sure. The R9 390 is, at worst (FurMark), a ~300W card. Maybe 320-350W for some of the AIB models with higher power limits configured. The i7-6700K CPU will be about 100-120W at stock during stress testing, and a few dozen more if overclocked. So even if the CPU is overclocked and the R9 390 card is a power hog (e.g. MSI), you'll be looking at 500W-550W max. And that's during torture testing; actual gaming consumption is much lower. Corsair PSUs are reliable, they can do what they say on the label all day long. You've got plenty of power.

Thanks guys.

It should be less than that because no game in the world maxes out 8 threads of an i7 6700K to 99-100%, while also loading the graphics card to 99-100% simultaneously.

Even a 6-core heavily overclocked Processor: Intel i7 4930K @ 4.7GHz + R9 295X2 (500W card) maxes out at 660W and i7 4930K overclocked is waay more inefficient than a stock i7 6700K and we are talking 2x290X cards in a 295X2.

Here is i7 3770K @ 4.6Ghz + R9 390 = 357W

People online exaggerate PSU requirements.

A r9 390 should be fine in a good 500w psu

Yep....Age can play a part as even the best will eventually degrade.

How about me ?
