Power supply for Radeon 290X Vapor-X OC

600 will be fine but id recommend more, i run 280x crossfire on a 750w although i cant overclock them.
 
I run an i7 4770K with a R9 290X using an OCZ 600W power supply.

Power usage at stock when under load is about 350W, overclocked 400-450W.

A good quality 600W power supply is fine.

The cooling on that Sapphire is good but you are paying a high premium for the overclock, which you could quite easily do yourself with one of the cheaper 290X's like the MSI Gaming. Could save yourself £100 and overclock yourself.

Even with the slightly higher overclock the difference when gaming will be minimal.

You need a better PSU then! I run heavy overclocked 7950's on a 630w PSU and power draw from the wall was never higher then 540-550w.

Are you sure arent 280x's supposed to be 250w draw anyone at stock? so thats 500w for me just from the cards at stock.

Thanks for the advice bud.

I'm running an i7 4770k at 4.4 with a massive overclock on my current 7950 without any problems so I'm reckoning I'll be fine. Love the look of the MSI too :-)

I wonder why more cards don't come with "blower" stryle coolers? My iceQ boost 7950 exhausts straight out the back of my case and even with a hefty OC never gets over 80 degrees. How much of a rise in temps do you think I'll see with a fan cooler that blows the majority of the air into the case?

I have a watt meter on my mains socket.... Here's a video I made.

My PSU is an 80% efficient bronze so 520w at the wall would translate to the PC itself only needing 416w

So your PSU should have no problems at all with 280x crossfire.

Things will get quite toasty unless you got good airflow, especially needed are fans to exhaust the heat outside the case as it will build up quite quickly and cause the gpu to throttle once it hits max temp.

It's all about how much airflow you have.
