Is my PSU bad?

[KnickNut3]

Hey. Been having power related problems (See this thread.) Realized that the variable speed fan on my Coolmax 450WCX-450B had been set to "low." I switched it high, but still am not sure if it's going to end up stable. (May take a while to rear its ugly head, and I want to know whether to send it back soon.)

Anyway, here are my voltages, etc., from the last 5 minutes surfing the internet. Are the -5V and -12V supposed to jump around a bit, or is my PSU in crap shape? Could some people post their own MBM stats for reference? Thanks!

idle pc uses very little power, it'll tell u nothing. i have never heard of that psu though

 

[KnickNut3]

Well, one of the last times it crashed. (I was wondering whether those voltages were bad even idling, that's what bad shape it was in.)

[HardWarrior]

Yeah, voltages are going to fluctuate a bit. Whenever I've had a PSU go bad the symptoms have always been far more overt. Look for things like hard shut-downs, or a rail dropping out entirely.

 

[Sentinel]

my psu is an antec true 380 and it stays around 11.71 - 12.00 on the 12v rail

 

[KnickNut3]

Yes, that's what I've been suffering from--hard shut downs during heavy gaming. Sometimes it takes longer than others.
See thread in OP.

 

[Operandi]

Sounds like your PSU is a POS, get a good name brand one.

 

[0roo0roo]

your numbers don't seem to mean much. thats normal fluctuation. but if its a cheap psu, not much to loose from buying a decent one. seasonic is good and quiet. go to silentpcreview.com recommendations section for information about psus

 

[KnickNut3]

It wasn't a cheap one. Newegg had it on a good deal, but it got rave reviews both there and here before I bought it. Coolmax 450W
