PSU won't turn on.

OCBeats · 07-August-06, 12:58 PM

I just got my Kingwin sli-ready 600w PSU. I plugged it in to the wall and tried to turn it on, to see if it worked, and got nothing. It came with LED's in it and they didn't turn on either. I hope its not DOA..... HELP

You did plug it into the motherboard, right?

If you'd like to see the PSu work you can jump the Green wire on the motherboard connector (the one with 20 or more wires connected to it) to any Black wire on that same connector. I would only do this to quickly see that it works, I wouldn't leave it on. It's bad for PSUs to run without a load (fans, lights, HDD, floppies) on the +3v, +5v and +12v rails.

I would use an insulated wire and just strip the wire for the ends that you're going to insert in the Green wire's socket and the Black (ground) wire's socket.

Do this at your own risk.

nah he can manualy jumper it....

green and black cables.. and a paperclip

milosh · 07-August-06, 01:40 PM

of course, you could do what my friend has done several times before (nearly losing his PSUs in the process) and insert a paperclip into the ATX connector in the right pins, which makes the PSU think its connected

granted, if youre the kind of person that didnt know to connect the PSU to a mobo, you probably wouldnt know which pins

that would then most likely cause you to kill the PSU, probably short a fuse in your house, and/or electricute yourself

EDIT: wow, i spent too much time screwin around while typing that, two people beat me to it

Yeah, I know the paperclip would work. I was just suggesting a safer (IMO) method incase he lets the paperclip accidentally touch something that it shouldn't.

Good short-cut suggestion, tho. (As long as you're careful)

thanks guys, i think im just going to wait till the motherboard comes next week. I don't want to screw anything up.

lobey · 07-August-06, 02:03 PM

Instead of a paper clip, what about this?

whats the deal with everyone telling him to test his psu when there is absolutely no reason to suspect that its defective?

running a psu without any load is a very good way to damage or destroy a perfectly good psu, so id recommend leaving well enough alone, getting your new mobo, and everything should be perfectly fine...

This is why I use a resistor.

hate to tell you this... but jumpering it will not kill the power supply... i have 2 power supplies one is jumpered... and its more then 3 years old...

some (newer) psus have something called no-load protection and will not be affected, other psus dont, you are safer hooking up a fan, hdd, or somerhing to your psu before turning it on in a testing situation...

i have destroyed at least 3 psus in this very manner simply because my supervisor was under the same impression you are...and it took 3 psus to convince him...

jumpering it properly wont hurt it, screwing up and connecting several wrong wires will if youre not lucky

u guess i have been really lucky...

but then again... when i have had the power supplies jummpered.... either a) it had nothing connected and was on for a short period of time

B) as in current state, i have mutiple hdds hooked up...

Hey guys,

i got my Asus motherboard in today and put in the case, i hooked up the 24 pin cord to the PSU and tried to turn it on. Here's where it gets wierd. I have the motherboard hooked up to the front panel on/off button. When i turned the PSU on, a light came on at the bottom of the motherboard - good so far. But when i actually hit the power button on the front of the case, the PSU turns on for just a second then shuts down. I don't get it. I really really really hope i didn't mess up anything - but im pretty sure i did it right. ANYBODY got thoughts on this??? THanks
