So I got this brand new rig with these specs.
Phenom II x3 720BE 2.8 GHz
MSI KA-790GX (sucky board, but nvm that)
WD 640GB
Sapphire ATI Radeon HD 4890
2x 2GB Corsair gaming ram(it costs the same as KVR that time)
I OCed my phenom II to 3.2 GHz at 1.3125 volts. I start doing full load tests, no crashes. Then I start increasing my HD 4890 volt to 1.4v and OC that as well. I start another full load test, it crashes and I had to wait a few minutes before I can start my pc back (typical psu overheating symptom). I can also crash the system by sending in 1.4 volts to my phenom II at 3.5 GHz btw(despite being stable).
Should I send this PSU back to RMA, or try an open-air system first to see whether my airflow sucks or not? Anyone has experience? I need to make a few comparisons. Sigh, I wish the fan would rev higher lol.
EDIT: A reminder, the psu is silverstone strider st56F
Your problem is the power supply already almost at limit. Once you overclock means you are pushing even more. Minimum requirements for 4890 is 500W.Phenom II x3 720BE 2.8 GHz

Get a higher capacity PSU for overclocking or just stay at stock speeds. Don't forget about capacitor aging. You will get less power supply after every year depending on how you use your computer.
