Overclocking R9 390 with 750W?

[ericchee]

I was wondering if Overclocking my R9 390 Sapphire with a EVGA SuperNova B1 750W would be safe? I've heard that the Bronze 1 ver of the EVGA 750W SuperNova is subpar therefore not sure about OC'ing yet

At the moment, my CPU is OC'd at 4.3Ghz at 1.1V

In terms of EVGA PSUs, I'd recommend them from the G2 , P2 , T2 lines, they are made by Superflower which make some of the best PSUs in the business e.g. EVGA SuperNova P2 750W Platinum Fully Modular Power Supply Unit
Other PSUs I'd recommend are:
XFX 750W XXX Edition 80+ Bronze Semi-Modular Power Supply
Seasonic S12G-750 750W 80+ Gold Certified Wired Power Supply

You have approx. 150W leeway so I'd recommend any quality 750W PSU

ah right I see I'm thinking of upgrading in the future to the G2 EVGA but that's not until a long time, but at this moment would you recommend overclocking with my current PSU or not??

this is an example overclock I will be trying to achieve in this video https://www.youtube.com/watch?v=UHtjwCYomL8

For npw, I'd say it's okay but I have to stress not to push your CPU in terms of overclocking because as soon as you push the PSU too hard the output voltage will be compromised.

ah okay thanks, but my CPU is overclocked at 4.3Ghz without having to change the voltages (1.1V was stock voltage) can I keep this overclock whilst OC'ing my GPU?

Yeah I'd give it a shot but if you run into stability issues then I'd avoid it

Thank you i'm going to go ahead and give it a go now
