420W not enough?

post #1 of 8
Thread Starter 
I seem to have run into a bit of trouble recently with my windows 7 box flopping out of the blue into a blue screen. I've ruled out the RAM- it's good, the GPU doesn't seem to be an issue- it's passed some long-held stress testing (about 2 days at 100% load). Now, I have no idea how to test a CPU for clarity outside of stress-testing it like everything else... so that's what I did for 2 days as well (prime95). I did it a bit of fuddled math and estimated my system is using about 350W at peak(?). Aside from the SSD (main drive) being about 1.5 years old, I have no leads for why the system inconsistently BSODs. Which is why I'm taking a whack at it and saying it's the PSU. Any ideas?

edit: my audio recently started lightly cracking when I did something like ALT+TAB windows or moved to a synergy client or star a song in spotify.

I'd rule out one thing at a time by dropping whatever is OC'd to stock. For example, put your GPU back to stock and see if it stops. If it's still BSODing, then put your CPU back to stock as well.

I tried CPU overclocking a while back but deemed my system unable to do so. GPU is back to stock now. It may be days before this thing BSODs.

420W is certainly enough.

I suspect your power supply isn't actually a 420W though. As I don't know of any quality 420W PSUs (400W yes, 430W yes, even a 410W or two--but no 420Ws). There are a great many power supplies with false wattage ratings out there (typically crap 200-300Ws in the $15-$20 price range and mediocre 300-350Ws in the $25-$30 price range, with any old wattage sticker stuck on). What's the exact model and brand of your PSU?

Wait and see. You'll never know if it's the culprit if you don't throw it back to stock and see if it was the issue the whole time.

kind of confused here... I killed synergy and its clients on the respective computers and the slurs seem to have stopped. I feel so stupid.

Oh. Guess there was one.

Well that should be a SeaSonic S12II, which is a solid design, so unless the unit is faulty or dying from old age it shouldn't cause any issues.
