i have a sapphire 850xt when i overclock it to anything over 550/570 the screen freezes and my moniter goes black. i think it has somthing to do with my power supply but i'm new at this and want a second opinion.

my rig:

amd 3500+
msi K8N Neo4 Platinum
sapphire 850xt
1 GB ram
2 - 160 GB raid 0
1 DVD-ROM
1 DVD+/-RW
420W power supply

I have this problem too but my PSU is weaker than that one even (surprised its held on as long as it has).

What brand is it, out of curiosity?

It is a Raidmax

Raidmax supplies aren't exactly known for their reliability under high load, so yeah, that may be the issue. I'd try picking up a unit from Antec, Enermax, OCZ, or PC Power & Cooling.

Fortron/Sparkle are great, and I would recommend then over Antec and Enermax.

I wouldn't....my friend had an OEM SParke PSU and he had nothing but problems. Replacing it with an Enermax solved the issue

Unfortunately thats something no one on this forum can really help you with.

I can only offer you the suggestion of buying it in cash and not telling her
