I currently have a Cooler Master GX 650 W psu powering 2 MSI Twinfrozr 7850 just factory overclocked in Crossfire configuration. When I'm in a game the PSU gets loud (FAN) and hot to where I'm like sweating near the computer. Then temperatures never seem to get too hot on the Cards or CPU (3570k @ 4.2 ghz). I'm thinking this PSU just sucks for any CF/SLI config. From all the PSU calculators this should supply enough power to my entire computer and not be a problem.

I guess I'm looking for some recommendations.

Thanks to anyone who can help.

What is the psu temperature while under full load?

I have no idea? How can I find that out?

Put your hand behind it and feel the exhaust temps :).

But seriously , unless you mount temp probes inside the psu unit or have an infrared thermal sensor gun that is about the best method that I can think of.

You might need a better airflow. Is the exhaust blowing on your carpet?

Nope the computer is on hardwood floor. Probably should just pick up a Corsair TX series 750/850 watt psu. The PSU worked great for what it was when I only had one card in, but since I crossfire it gets too warm for my liking.
