I just finished putting my computer together, and it won't start. I'm thinking it's my PSU. I have a Cooler Master Extreme Power 430W PMSR/P that has to power: ASUS A8N-SLI Premium AMD Athlon 64X2 4200+ Zalman CNPS7000B-Cu LED heatsink/fan Corsair XMS2gb (1gb x 2) RAM eVGA Geforce 7600GS WD Caviar 80gb HDD WD Caviar 500gbHDD BenQ 1650 dvd drive BenQ 5232 cd drive (although I unhooked this to see if maybe too many things were plugged in) a 56k modem Plus, the 120mm and 80mm fans in my Centurion 5 case. Right now, it's set at 115Vac in the back. When I plug it in and turn the supply on (with the I/O switch or whatever you want to call it), I can hear a clicking noise from inside of it. When I hit the power switch on my case absolutely nothing happens. My only other guess is my case's power switch isn't hooked to my mobo correctly. I drew a picture to help explain. My case's connectors had arrows that went to the pins with plus signs on my motherboard's panel. The power switch and reset buttons didn't have those. Here's how I connected it (I only drew the power switch, but that's how I connected my reset, too). Can anyone help me?
Double and triple check all your connections.I have to leave for work now...I'll check back later. Good Luck. Check c-mos jumper.
what country are you in as north america is 120v & europe is 220v. make certain the ide cables are not in reverse as in pin 1 to pin 40 instead of pin 1.
Just for testing, you can disconnect the power connection from the mobo, and use a small screwdriver to "jump" the two power connections. Be careful when you do this...make sure you touch the correct pins. You only need to make contact for about half a second. If everything is hooked up properly, jumping the pins should start the PC. If this works, hook up the reset button to the power connections on the board and see if the reset button will power the PC up. If so, the power button is bad in the case. OK, dumb question time. Dont be offended. Someone asked if the square 4 prong connector was hooked up. You said it was. Is the main one hooked to the board as well? I would reseat the main ATX power connector and see what happens. Random thought: Did you use the correct mobo spacers when mounting the board? You sure nothing could be grounding out on the back of the board? ~Rich
I'm in America, so 120V. I checked all the connections, including the ones to the mobo, and they were snug. I don't think I'll try that jumpstart thing. I'll try to see if anything's touching in the back, but it might be hard. Some other sites said the PSU won't be able to handle that load and might damage something, so I've been kind of freaked out.
try these to see if psu is good enough. http://www.jscustompcs.com/power_supply/ http://www.vbutils.com/power.asp
Disconnect everything but the main hard drive, video card and one stick of ram...see if it will start up then.
