PSU voltages

[JLuchinski]

OK so I've been having problems with random lockups and I've been thinking it might be my PSU, the one in my sig. I sat for 20 minutes watching the voltages in the BIOS and I read the following: CPU 1.432 volts, 3:3 fluctuates between 3.254 and 3.96 volts and 12 stays at 12.192 volts. Is that stable? I don't have a clue to what any of this means so any help is greatly appreciated. I'm going to run Memtest all night to rule out my RAM hopefully.

OK so I ran Memtest all night and there were no errors. I downloaded Speed Fan and these are my voltage readings. Is it just me or is 6.71 volts out of 12 volts a bad thing? I don't know anything about these readings so someones input would be greatly appreciated. :good:
:Edit: Dammit why did that turn out so small? Anyways the readings are as follows: 3vsb: 3.41v, vbat: 0.00v, +12v: 6.71v, AVcc: 3.30v, 3Vcc: 3.28v, VIN1: 1.01v, VIN2: 2.04v, VIN3: 0.00v, Vcore: 1.22v, +3.3V: 3.30v, +5V: 5.04v, +12V: 12.19v.

Well the voltages in your first post are fine. What do you mean in your second post in, is 6.71 volts out of 12V?

Install PC Wizard and see what the P/S voltages are reading.

I normally dont fool with speed fan, but your voltages on the right seems ok. Dont have any idea what the +12V/6.71 means. If it was at some point it dropped to 6.71V, thats not good.

OK so PC Wizard is telling me this, 7.03 on the 12v. I'm guessing that's bad?

Looks like your 12V is fluctuating pretty bad. Not good, if so you need to replace your power supply.

OK thanks. So would that explain the random freezing? I'm going to pick up a new PSU today. What is the best kind that you would recommend for $100?

 

[StrangleHold]

PC Power and Cooling Silencer 760W, not the MKII series
Antec High Current Gamer Series HCG-750
CORSAIR Enthusiast Series TX750 V2 or CORSAIR Enthusiast Series TX750M
SILVERSTONE ST75F-P 750W
XFX Core Edition PRO750W or XFX PRO750W XXX

What store do you go to get your computer parts? I would pick a good antec or corsair unit.

My local computer store: www.memoryexpress.com
I guess you could say they're the local Newegg

Awesome, thanks. It's not modular but oh well. There has been a lot of construction going on in my area as well as a lot of power outages so I suspect that is what has caused my PSU to fail. Looks like it's time to invest in a UPS as well.

What about this one? http://www.memoryexpress.com/Products/PID-MX23281(ME).aspx

What about this one? http://www.memoryexpress.com/Products/PID-MX23281(ME).aspx

I would not get it. Its a 700W, but only has 552W on the 12V rail with 46 amps total. The Corsair is 750W, with 720W on the 12V rail with 60 amps total.

Your Cooler Master case has pretty good cable management, so hiding the leads should not be a problem.

I ended up getting this one: http://www.memoryexpress.com/Products/PID-MX26068(ME).aspx

I notice a big difference in speed and system responsiveness. I played Modern Warfare 2 for 3 hours without a hitch where as before I could play for 10 minutes max before it froze. Thanks for all the help, if there was a ranking system I would give you a +10.

Figured it was your power supply. Glad you got it running right.
