Help with Crossfire 7850 and current PSU

dschutt84

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?

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.
