Power Supply hurtin my overclock

Ive been having a few problems with my system(any speeds higher then 204X11.5) but cant pinpoint the problem. The problems are usually crashes to desktop. Since I installed the 5900 it doesnt crash to desktop it reboots. Everyother component of my system seems strong so im leaning towards replacing PSU. It is a tiger pro 360. It says is combined 3.3 +5 = 200 watts. I have BFG 5900, sata raptor, 1 burner 1 regular cdrom, 4 80mm fans, 1 harddrivecooler with fan. My +5 is always below +5 usually around 4.7/4.8 as well as my +12 at like 11.8. What would the pros here do?

Not sure about that brand PSU you have, but even
the specs on the side are often VERY misleading.

You might try a good 530w PSU like this*

Since you have Raptor SATA drives you will likely need
SATA adapters like this*.

Hope that helps.
