Is a 750W PSU enough for a r9 390 and fx 8350

I am wondering if a 750W PSU is enough for a r9 390 and fx 8350 paired together with a fan controller connected to it with 6 fans connected to the fan controller

At stock clocks it will be fine, but be careful overclocking. You could find the limit of the PSU depending on quality.

A high leakage FX-8350 can run 250-300W (torture/stability testing) just to get a stable 4.7ghz. That's JUST the chip, doesn't include VRM conversion loss's. (add another ~40W!). An overclocked FX-8350 build can pull near 400W from the PSU with the GPU sitting at idle. The R9 390, depending on the version you have, can operate ~280-330W maximum. You can see how such a build could eat an entire 750W PSU pretty easily.

Wow..

And to think my 5820K with a GTX 960 is setting hear purring along at under 150 Watts even with 30 Watts of that coming from the Monitor..

Might Overclock when winter comes and I need a bit more heat in the house Grin

Thanks for your input !!

Fire up P95 + Furmark. Should get at least ~300+W from the wall.

Just ran phoronix-test-suite run gputest and did Furmark..

Amazing how you hit the Power Draw exactly. It hovered between 290 and 305..

Thanks for your input !!

Plenty of power. You could even go with a 650w. What is your power supply?
