Possible PSU Problem

J Dev · February 24, 2006

I have recently built my Dream System( about 3 days ago). Everything works fine except for when I power the system down. After shutting down (thru Windows) the system will not power back on unless I unplug it. I have to unplug it, wait for about 5-10 seconds, plug it back in and it will power up. I have tried unplugging everything, flipping the switch on the back of the power supply and pressing the reset button. All I get is the green LED on the front of the case which means that there is power to the system but nothing else turns on/boots up . If the system goes into standby for a while I just have to press the power button and the system starts up again(like it should) but if I shut it down---nothing!!! :sweat: I (of course) suspect it is the power supply but before I go out and buy one I just would like some help. I am running Windows XP Pro SP2, and It passes S&M's tests. If there is some way for me to test the power thru software that would be great. Also here are the readings printed on the outside of the PSU +3.3 17A +5 25A +12 14A. Also what voltages do the 4 pin molex connectors use. Do they use 12 v or +5??? Any and all help would be greatly appreciated

Check out the link in my sig. for recommended PSU’s! You need a new one if you only have 14A on your 12V rail! DFI recommends at least 28A and 480W (native 24 pin) for none SLI set up! :shake:

Thanks for the help HITANDRUN. I figured it was the PSU but I thought I would post a thread and get as much help as possible. This is a PS that I thought may work

I know this one is not 28A at +12 but it is very inexpensive. let me know what you think. Also I have'nt done much with the system as of yet. I plan on overclocking to about 2.4 or 2.5 and thats about it. I will be doing the usual things with it like burning CD/DVD's and a little gaming but nothing too extreme.

Don’t know about the PSU you picked! I don’t want to recommend anything which is not proven to be running good with the DFI boards! Check out the “Best bang for the buck” PSU’s below. Maybe you like one of those! Some links are not working so you will have to do your own search! I personally own the SkyHawk one and it’s been running like a dream from the first day!

These are the "BEST BANG for the BUCK" PSU's: :shake:
