Hi,

I just ordered the Sapphire R9 290 Tri-X OC from Newegg and it's on the way. I just want to know if my 650W NZXT HALE82 PSU will be good enough to support my GPU along with my i5 4670K. I also have a 1TB WD HDD and a Samsung 840 EVO SSD. I plan to overclock both my GPU and CPU a bit and I don't know if I will have enough power.

Thanks!

my friend is running r9 290 with PSU like that, so he doesn't have any problems with i7 4770K stock clock.

with that psu is hard to say but i think you won't be able to OC even one of them because you are on the limit with that PSU. GPU 550~W + CPU 80-90~W so you are on the line i guess.

Hi Akhilcool
The Radeon R9-290 requires a psu with 31A on the +12v rail and a 550W psu minimum
Your 650W NZXT HALE82 PSU has 53A on the +12v rail and more than enough wattage for your card and overclocks

Yes; you should be fine. The NZXT Hale82 650W power supply is a good power supply. It provides a total of 53A continuous current on the +12V rail. The GPU itself only needs a minimum of 23A. Even with everything else, you still have plenty of headroom left for overclocking.

Thanks for the reply! I guess I probably won't need to my PSU after all.

Interesting. Where are you getting that information from? The TDP for the R9 290 is 275W.
