New PSU Problems

[TFM]

About a month ago, i purchased a PSU from someone here at AT that was a reviewed PSU.

PSU - Tagan Silver Guardian X 1000W

For reasons that aren't important, i hadn't had an opportunity to install it until tonight. So after installing the new PSU, i turned the computer on and got nothing. Some LEDs tried to light up (on fans) and i thought i heard something trying to start - but nothing.

A mobo LED stays lit, as well as a red LED on the back of the PSU.

Knowing this was a reviewed PSU, i can't imagine that it would be defective. What could be the problem?

So far i've...
Double checked the PSU connection to the mobo
Checked for 110/220 - no option on the PSU to change it
Switched the power feed to the hard drive with another one
Checked to make sure the outlet works
Maybe something else - it's late and i'm very frustrated and scared that i just lost $150

Can anyone think of something that i'm missing?

Thanks,
Chris


EDIT:
Here is my system:

Mobo: SY-P4I865PE Plus Dragon 2 (Soyo)
CPU: P4 3.0c (Stock Cooling)
RAM: 1.5 Gb PC3200 (3x512)
Video: BBATI X850XT
Sound: Turtle Beach Santa Cruz
HD: Western Digital 160 GB PATA
Optical: BenQ DVD-ROM (can't remember model), Generic 52x CD-ROM
Floppy: 3 1/2" Floppy Drive
NIC: Generic 10/100 NIC

Before, i had an Antec TP 480 attached to the system and everything worked just fine. I shut it down, took out the Antec, put in the Tagan, and nothing.

I double checked that both mobo connectors were connected (including the 4-pin one)

I already tried shorting out the switch on the mobo with a screwdriver - same result

The fan on the PSU does not seem to be spinning up - but i'm not sure how to short it out myself. Does that require taking the PSU apart?



SECOND EDIT:
To update - i connected the PSU to another computer and got nothing there as well




THIRD EDIT:
OK - another update - i tested the PSU by putting an unrolled keychain (couldn't find a paper clip) in the green and black spots and when i plugged in the PSU the PSU powered the LED fan i had it connected to - does this mean the PSU is NOT dead?

what MB? do you have both of the MB connectors connected? I have been building PC's since you could buy parts, and I'm almost embarrassed to say, but a few times I've forgotten to connect the 4 pin one. is the fan on the PSU spinning up? if not, find the pinout diagram in the book that came with it and short it yourself to see if you can get the fan spinning, it's late as hell or I would explain more, dunno if you know how to do this. I'm sure if not somebody else will post which ones, my brain is fried and I don't want to give you bad info. If you do this and get no fan the PSU is bad, if the fan comes on, then it's either MB or connectors.

you also didn't mention if this PSU was installed on a new MB or one you had working before with another PSU.

good luck.

I would try would be to unplug all molex/sata power cables and see what happens, I know you said you switched the HD one, but it's good to strip the system down to the bare bones. One last thing, it is possible to have a short in your power switch so short the power switch jumper on your MB with a screwdriver and see what happens. Probably not either of the last 2 I mentioned, but it never hurts to try everything.

again good luck I'm sure you'll get it working

Thanks again - and any other help would be appreciated

To update - i connected the PSU to another computer and got nothing there as well

Not a fan, not a noise? Only Led?
Well, I know exactly how frustrating that can be, but I think that one is gone.

Could it be that the PSU is being used on older boards that look for -5v? If so, then no modern PSU would work on those boards.

Well - i re-hooked the PSU to the mobo i hooked it up to earlier, and this time it started up fine. I re-hooked it up to the main mobo - (with the mobo now out of the case and on a table to make sure there were no shorts) and nothing

The mobo in question is a relatively new mobo - not sure what the -5v issue is, but even the Antec that was running before is not working with it now.

So i'm thinking it's the mobo - my question now is this: How much could the CPU affect it?

Well, if it's working with any other system, it's not a bad psu. And no, a Soyo motherboard with an i865 chipset is not a relatively new motherboard. Intel has released something like 6 chipsets since that one, and Soyo doesn't even make motherboards anymore. And unfortunately for you, it sounds like you killed your motherboard. That can happen, if you for instance, have the psu plugged in when you attach either plug to the motherboard, or when you install the RAM, etc.
