I have an oldish ATX motherboard in my PC with a 20 pin power connector. The quiet power supply I have just bought has a 24 pin connector with 4 removable pins on one end and is ATX 2.01 rated.

If I remove the detachable 4 pin block, will this power supply be back compatible with an ATX board?

I would have thought so, but one pin (the -5V) is not fitted on the new connector, but I cannot remember if it does anything on the old style one anyway.

Help appreciated.

Chris - I had this recently.

Flummoxed me for a while (until I'd finished with all the curses and spotted the block was detacheable).

Removed the 4 pin block and all was OK.

The extra pin you mention I can't envisage / remember so can't help with that.

I will go for it and see what happens. Was supposed to fit the new PSU and quiet case fan tonight, along with a nice AGP 8X card with DVI output for the shiny new Samsung widescreen. ***** at Dabs sent a PCI-E Graphics card. Their error. Their labelling on box says AGP8X, the manufacturers label says PCI-E.

Boom - funny, thats what happened to mine

No, seriously, all was well

The 4pin block is an extra CPU power supply for newer Intel boards. The other block is standard ATX & will be absolutely fine.
