About to thow in the towel! Help needed with new build.

[jasonj7777]

Well, I'm having issues. I have everything hooked up and when I power my system up the power just cycles on in short pulses. The fans run for about 1 second then power off, then they run for 1 second, then power off. This happens until I unplug the power unit. Also, I have no picture on my monitor.

System details:

OCZ ModXStream Pro OCZ600MXSP 600W ATX Power Supply
HITACHI Deskstar 1TB Hard Drive
Intel Core i5
Cooler Master Intel Core i5 compatible Hyper TX3 CPU Cooler
GIGABYTE GA-P55-UD3L LGA 1156 Intel P55 ATX Intel Motherboard
SAPPHIRE 100284L Radeon HD 5750 Video Card
Patriot G Series ‘Sector 5’ Edition 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333
Antec Three Hundred Black Steel ATX Mid Tower Computer Case

Thanks for the help. Both power connectors are in the motherboard and the video card is connected to the PSU as well. Actually, I get the same results when I disconnect the video card completely.

I'd say its your PSU. If you are able to, get a PSU that is known to work fine (from a friend perhaps) and try it out with that. If your system works then it was your PSU, if not its time to start re-seating everything.

Hmmm, I'm going to see if I can borrow another PSU. I'll let you know how that works. Do you think my 600W PSU has enough power for this system?

 

[Griffolion]

Yes its definitely enough, even if you were running crossfire, but you've perhaps got a faulty part or broken connection somewhere inside your PSU. The power regulation circuits are incredibly fragile and may break on unlucky occasions.

 

[jasonj7777]

Just got a text from my friend. He has a spare 480W PSU. Would that be safe to use?

 

[Griffolion]

Yeah that would work fine so long as you don't put the graphics card or CPU under any major load, which i doubt you will unless you start running prime 95 and 3d mark at the same time .

 

[jasonj7777]

Nice. He live around the corner, I'm going to see if I can pick it up tonight. I hope it solves the issue.

 

[Griffolion]

The sooner the better, good luck with it.

The READ before posting about boot problems! sticky at the top of the forum was created to troubleshoot this type of problem. The checklist gives you a way to methodically troubleshoot your problem instead of randomly swapping out parts. You should go through every step in the checklist.

Thanks Shortstuff. I'm going to start there.
