is this a PSU issue?

[Cereal Killer]

I have the Antec Neopower 480W and I have played games with my CPU and GPU overclocked at the current speeds for some time now and I've never had a problem until yesterday when it restarted during Half Life 2 and then today it restarted during F.E.A.R., my specs are in my sig.

I'd say it's your OCing before I'd say it's your PSU... Granted, 2.21GHz isn't high for a 3000+, but that also wouldn't strain a PSU too much..

this might be a weird coinincidence but it first did the restarting thing when I added a second monitor, even though I disabled it when I played F.E.A.R. today, also, my temps are fine, so its not a temperature issue.

have you tried monitoring your voltages under load?

download everest and run it while running rthdribl and prime95. perhaps your voltages are dropping just enough under high load.

I couldn't really use Everest to monitor the voltages because it's a trial only, but I ran the torture test in Prime 95 for arond 45 minutes with no errors and I ran 3DMark 06 with no problems. Should I worry about this?

well I downclocked my CPU to 2.16 ghz after it restarted while running a virus scan

Multimeter.

I don't have a multimeter but it didn't restart once I downclocked it to 2.16 ghz and played F.E.A.R. for 30 min or so.

here are my current voltages

definetly looks like a PSU issue. probably can't handle the extra draw of the overclock. i'd either RMA the PSU or grab yourself a new one. This would be a good replacement.

Without checking it with a multimeter or swapping in a different PSU there is no real definitive answer.


However, since it is overclocked and dropping that back to stock seems to have solved the problem i would bet on your OC....since well by definition that isn't in spec.
