Suggestions welcome.

I'll try and keep it as short as possible....

I bought a corsair hx620w PSU at the weekend to put into a 2nd pc.
connected it to an Asus p5n32 sli se deluxe Motherboard and installed windows, updated/installed software etc.

I came to switch it on tonight and nothing happens, looking at the motherboard shows a flashing green LED. (nothing in manual troubleshooting for this)

Tried all of the disconnecting and reconnecting one at a time to no avail.

So I took the psu out and put it into my other PC and connected all plugs and it worked fine/booted into windows?

So I then took the Enermax Galaxy 1000 from that PC and connected it to the P5n32 connecting all plugs etc and that worked fine/booted into windows?

So thinking I'd solved it I put them (corsair/P5n32) back together and the green LED still flashes? :confused:

Hopefully someone will have suffered a similar problem,

Thanks.
 
If the green light is flashing that means you're not getting proper 5v from your PSU (apparently)

Does this board need both a 24 pin and 8pin (2x4) ?
 
Yes it has both, also the other motherboard I tried it in also has both but it works in that one, it's as if they just dont like each other. :confused:

It could be something like a pin on the 24 pin ATX or on the motherboard, but when I swap PSU's around and they both work then it surely rules things like that out?

Maybe theres something in the 5v side, its not pushing out enough 5v for one M/B but it is for the other?
 
Whilst its rare it isnt unknown for mobos/psu's to not like each other (technical term, lol) though havent heard of it with asus boards before, evga a few times but not asus

Yeah it's looking more likely to be the case, I tried an Antec Neo power 480 and that worked fine.
It works powering a Gigabyte M/B + 7800GTX and an Asus Striker + Q9650 + 280GTX so its not like its got an obvious problem or just not got the oomph. :confused:

Whats more baffling is that it DID work enough to install windows and updates etc......

Thanks anyway for suggestions........:)
