no boot w/ATX 4Pin attached, boots without it

[nebuchanezzar]

If I boot my new system from a cold state with the P4 plug no boot. It dosn't even power on enough to spin the fans all the way around.. I then have to flip the switch on the back of the psu to try again. If I remove the 4 pin it fires right up no problem.. I can then install the 4pin and reset or restart with no problems. This is all with the OCZ 600 Powerstream...no problems with the Fortron 530(an old one). Tried removing hardware...took everything apart...tried different video cards...just video card, PSU, mobo, and fan for the XP90 all the same...any ideas other than to RMA by PSU??

DFI nF3 UT 250Gb w/ 3200 DTR
2x256 KHX BH5
OCZ 600 Powerstream
BFG 6800oc
2 SATA 160Gb and 80Gb

I'm currently typing with it right now in pieces sitting on a coffee table..it runs fine after the initial "quirk" I have it running HTT:FSB 1:1 at 240 and cpu at 2.4Ghz and it's stable. I originally posted over at bleedinedge

I have heard that the Powerstream 600 has some issues, and considering that it works fine with the Fortron, I am guessing that it is the problem. You would still get plenty of power for anything with a Powerstream 520 if you could get one, are you still within the exchange period? Otherwise, I would reccomend RMAing the Powerstream.

Hi, This is a little far out, but sounds like the 4 pin plug is miswired and placing a short on the PSU. PSU has circuits that shut it down or don't let it power all the way up when a short occurs. Check the plug in your MB manual. Jim

Thanks for the input guys...I've emailed OCZ and want an RMA for it. Even my POS TTGI that I have in my sons computer does just fine. It's new so OCZ should replace it.
