24 pin connector -conversion

  White_Elephant 11:56 25 Mar 2007

Starting a new build for my older brother and realised that the mobo i just bought - an Intel LGa775 type to go with the E4300 processor, has the new 24 pin power connector but the 400w power supply i wanted to put in it is 20 pin.

Had a search around the internet and discovered that you can buy 20pin to 24 pin adapter cables very cheaply from Maplins.
Is this the right thing to get or do I need to buy a brand new psu with 24 pin connector?

Im not intending to run anything in sli or overclock.

The adapter you mention is the type you need - however you may well be able to get it cheaper elsewhere.

They do work but i think there is an issue with power hungry set-ups and are only realy designed to be used with PSUs 400w upwards so yours is on the lower limit so you may not be able to optomise your system..

it is also quite hard to tell, particularly on overclockers.co.uk website who dont give good amounts of detail on their products (shame on them) which psu's are 20 pin and which are 24 pin?

Is it denoted by the atx version? atx2.0 or atx2.2 compliant? which verion will carry a 24 pin connector?

Just bought a new psu from

for the same board. It is silent and the cables are modular for better air flow.

According to the link atx 2.2 is the one you want.

Some 20 pin power supplies come with an extra 4 pin connector to suit 24 pin connection.

my current psu has a 20 pin connector plus a seperate square 4 pin. Can i connect the 20 pin to the 24pin mobo connector and the psu 4 pin to the atx12v connection, will that suffice?

Then you don't require an adapter as the four pin supplies the CPU power.

I have the split 20 pin and square four pin connectors from my 500w PSU which work fine with my MSI KT6V motherboard.
