Power Supply Problem

Hi everyone!

I just got a new motherboard in my computer, as my old one died, and after installing everything in it: I think my power supply died.

I have only the neceseties connected. And yes, i've double and triple checked EVERY connection in my computer. what happened was: I was attempting to fill my new liquid cooling system, so I turned the computer on, and left it for about 30 seconds while filling up my bigwater 745. About 30 seconds into the filling process my computer shut off. If I give it a minute, and unlpug it, then plug it back in, when I press the power button everything lights up for about half of a second, the shuts back off. I then attempted switching my red switch on the power supply from 115 to 230, and turned it on, everything will then turn on: BUT, I have no video signal, and the power button won't let me turn it back off. So, basically what I have here is a power supply that turns off when on 115, and hardly works when running on 230. My systems stats are below.

Please, any input would be wonderful. Do you think my power supply just died? Why? Thank you!

 

the little 4 pin power connector, that powers the cpu, is it plugged in??

 

Ian how you are getting it to work on 230 volts is beyond me, as both legs are hot on 230, were as only one is on 110. Probable the reason the other MB crashed was due to faulty PSU, hey at least they are cheap and easy to replace versus the MB.

My advice chop & chuck that old PSU

 

BCGray, Ya know what... yeah: that could be VERY true, I didn't even think of that. I think that I'll order another PSU tonight. Thanks a bunch for the advice.

kjanz: yes, it's plugged in

More notes:

I let the computer sit for a while, then I decided to reset the BIOS by removing the battery, and moving the jumpers. After setting the BIOS to default, get this: It worked! Akward? Anyways... I then turned the computer off as I had to do something, and let it sit for about 25 minutes. After coming back to my computer, I found the same problem that I was getting before, it just turns itself off immediately. So, again I reset the BIOS, and it worked. So this is what I need to know: is it my motherboard, or my PSU? FORTUNETELY, I am going to be getting a backup ASUS A8N-SLI Deluxe Mobo in about a week, AND I will order another PSU if I get enough people on here that can convince me that the PSU is the problem.

 

I keep a good PS around all the time. I have seen them do alot of differnet things so,PS is one of the first things I hook up(I just hook it up outside of the PC)That cuts out the guessing. Get a new one if it's not the PS then you have a spare.Chuck(my name)

 

AH HA! I think I may have found my problem. While installing a couple of PCI devices, I was waiting for the computer to shut-down. Well, I noticed that the HDD and Power LED's were not lit. So, I looked at the connectors, and they were all in place, and secure... they were however, upside-down, or downside-up, however you'de like to say it. Anyways, I reversed the connectors, and I haven't had a problem yet. (Crosses fingers). I'll post more if I have any more problems,

Thanks for the input!

IanTheGeek I still think you should get a PS.I don't think you should be switching the ps to 220, I'm a electrician and I've never seen anything good happen when running the wrong voltage to anything.Chuck

 

Hahaha... That's a good point! I'll order another one online (yesterday was my b-day, so I guess thats where the money's goin'). Yeah, I'm about half way through my Electrical Engineering degree, and I have done a couple of labs on power supplies. One thing that I've learned about the PSU that I am using now, is that it has a failsafe circuit that will not allow it to have a larger than normal output voltage. I connected a multimeter to all of the outputs to test the voltages and current, everything was normal. So I don't think that it's gonna fry anything, but yeah... I think I'll be buyin' a new one anyways

 

Hey HAPPY BIRTHDAY IAN even though I am a day late, and glad you found the problem, chalk it up to the Birthday blues. I agree with cepy123 a spare PSU is cheap insurance against the blue screen blues. Maybe cepy123 should change his moniker to ChuckPSU

 

Hahaha! Thanks! Yeah, chuckPSU... has a nice ring to it... lol Thanks a bunch everyone, I bought another Ultra X2 550 online today.

 

Ian you should fill your water cooling setup out of the case and let it sit for 24hours on some cardboard checking for leaks only then should you install the completed filled system,if the water level has dropped during use you may have a leak and must be investigated
