R9 390 Overclock Power Consumption

[Jadester]

Hello. This Holiday season I was planning on buying either a GTX 970 or a R9 390 as an upgrade to my current build.

I would like to get the 390, but I only have a 550w power supply. I have read some sources say that you could run the 390 with a 550w power supply, but how would my overclocking potential be? Would I face problems?

tl;dr: With a 550w power supply, would I be able to run an overclocked r9 390, or should I go with a 970 to overclock.

A 390 under worse scenario will draw around 300W of power. If you take into account the CPU and other components, that'll probably add up to around 450W of power usage (again under worse conditions) so as long as it is a quality power supply with a legitimate 550W and good amount of amps on the 12V rail then yes it's fine.

Thanks for your help. This is the power supply I've been using, and I believe it to be reliable (I hope so considering how many people I've reccomended this build to). Would this be fine?

Yes very good power supply.
Made by SeaSonic for XFX.
Will handle the system overclocked without a problem. Unless you are running a AMD 95?? chip which consumes 220 watts by itself.

Thanks, I'm using a 4460 on a H97 chipset so I should be fine
