PSU and power comsumption doubt

[manupa14]

Hello folks, I wanted to update my 7970 ghz for a r9 290x and i was wondering if my PSU would suffice. I have a 4670k 2tb western digital 6gb 1333 Mhz of ram and most important a Cx600M (46A i believe) Will the PSU be able to handle the r9 290x under load?

It should, however I would look up the minimum wattage requirements for r9 290x.

I'd say you'll be fine as long as you don't overclock your GPU, and your CPU isn't heavily OC'd.
Anandtech (http://www.anandtech.com/bench/product/1059) measured the total system power under furmark and heavy gaming to be around 400W at the wall. The means only about 350W-360W being pulled from the system. I believe their test machine is a more power hungry X79 platform too. If you simultaneously put the CPU & GPU under synthetic power draw (like furmark + intel burn test at the same time) you could no doubt exceed 360W, but I still don't think you'd be anywhere near 600W, and that's only under a synthetic (not real world) scenario.

If I were you, I'd be nervous about significant overclocks on either the GPU or CPU, but otherwise I'd feel safe enough running that machine on that PSU.
