Is this power supply bad?

post #1 of 22
Thread Starter 
A few months ago the stock power supply in my moms computer up and died. wouldn't turn on at all. against my better judgement we went to a local computer shop and picked up a cheap Logysis 480W PSU, for $30 or $40 (available for less than $20 on newegg). recently my moms computer has been acting up alot, so far that it has had several memory-related BSODs, eventually leading to a corrupt OS (wont boot up, just keeps restarting). I checked the memory with memtest86+ and it ran 2 passes just fine. i checked the PSU today with a psu tester and the 3.3v is reading HH, or too high. Is this what is causing the computer to crash?

If it is, help me convince my parents not to get this psu replaced with the same one....

Logisys is pretty much always bad, I can tell you that much. Whether it's the cause of your problems, I can't say for sure. If the voltage on the +3.3V is indeed too high though, that would be a problem, not just for stability but also for the life expectancy of all your components that use the +3.3V rail.

RAM runs off the 3.3v so that could be what's causing your problems. Logysis is pure garbage.

yeah... if 3.3 is above about 4v thats going to cause quite a few problems, voltage regulation may drop as a lower quality PSU degrades :/

There's no Antec Earthwatts 350W as far as I know, but the 380W unit is perfectly decent

ahhh yes 380, thanks guys

probably a dumb question, but that should be enough for a pentium D and a 4550 right?
