533460 2007-03-16 04:19:00 Hi all

I'm replacing the PSU on an ASUS A7V400-MX with a 450W supply.

The old PSU and the slot on the mobo has 20 pins, whilst the new PSU has 24. I read on the 'net that the extra four pins are really "extra", and that the PSU should work with a 20-pin mobo power socket.

Can I just plug in the 20 pins that fit and it'll go? Or do I need to buy an adapter from 24->20 pins?

Thanks in advance

Like the PSU's here have a 20/24 PSU too, but the 4 extra wires arent connected to the other 20, but can be used if I get a mobo that needs them.

The 24 pin PSU's are for some more recent mobos.

533462 2007-03-16 04:31:00 No, the 24 are in one plug, but it WILL plug in with the extra four "hanging" over then end. It doesn't work like that, tho' ... so maybe I need the adapter? davehartley (3487)
533463 2007-03-16 04:39:00 Might be spaced out enough so the 4 hang over the side of the 20 pin connection. Best thing is to ask the shop where u buy it from.

If theyre wrong take it back.

Yes, the extra 4 will just hang over the edge . Works fine . ,

533465 2007-03-16 04:52:00 OK ... so if it doesn't go (and the original PSU still powers the thing up), I can suspect it's a dud PSU? davehartley (3487)
533466 2007-03-16 04:56:00 Most if not all 24-pin PSUs have the remaining 4 pins detachable. All my 3X 24-pin PSUs can detach 4 of the pins. qazwsxokmijn (102)
533467 2007-03-16 04:59:00 Unfortunately this one doesn't ... the plug is one molded piece :( davehartley (3487)

Probably.
