hmm might be faulty
BUT it sounds like theres a short somewhere
u got anythign like cold cathodes, lighting, etc installed? Try unpluggin that real quick

no, i dont use any of those things, everything just plain normal, 7800gs, 3ghz processor, 1gb mem, 3 sata hd´s sound card, dvdrom, dvdrw nothing fancy.

i really feel left out, i waited for this psu for so long.
do u think i should try moving the volt regulators to test it ?

nah not yet
disconnect EVRYTHING except the ATX connector and see if the mobo will turno n

Was this a working PC before and you just switched out the PSU or have you been putting this computer together and the PSU is the final piece?

was a working pc, just changed the psu and the video card.

i just did what u asked me to do, disconected everything, and the same thing, all fans make a quick spin including the psu fan, just a quick one and then nothing happens.

jonny doesnt this sound like a short soemwhere to u? thats what it soudns like to me

I agree, could be a short. Disconnect everything except the 24 pin and 4 pin connectors and see if the mobo works, if it does, then slowly add things that are needed to get it to boot into windows. Take out you ram and reseat it while you're at it.

[watson1987]

unplug everything and try jumping the psu with the atx plug

ground the green wire (ie paper clip in green and any black plug)

if it shuts off instantly with that then its toast, if not probably parts (or still faulty)

[jonnyGURU]

Sounds like a short, but when I swap parts out of a working machine I'm going to look at the parts that were swapped out first.

Put your old video card back in with the new power supply and see what happens.

If the card is bad, and causing a short in the board, not just at the AUX power connector, it'll have the same effect. I've seen some defective cards with shorts that ended up torching the slot!

Also do the green-to-black test that Watson suggests. This eliminates all variables leaving only the power supply.

Does this psu have the P4+ and the E plugs that look exactly like the regular P4? If so maybe you plugged in the wrong plug to the board.

ok guys, i did what u guys asked me to, i disconected evrything but the 2 psu to mobo conectors, i tried to turn it ON an the same, just 1 spin of fan of the psu, 2nd try alonger psu start, the third, as amazing as it sounds the PSU finally started and was running good, so quickly added everything and the machine was running just fine.

I havent tested it really much but for what i have seen, my pc seems to be pretty stable atm. I dont know what happened there but im glad the psu finally worked.

thx alot for the help guys, this was weird one
