Please log in for more thread options Hi, I've just purchased a load of bits, including an Antec Sonata case (lurvily!!) and an Asus A8V-E deluxe motherboard. However, it appears I have a problem.. well I hope not, but if anyone can help I'd be grateful. On the motherboard, there is a 24 pin 'EATXPWR' connector and a 4 pin ATX12V connector. It says that an ATX 12V specification 2.0 compliant PSU should be used (which I thought mine was..). However, on the Antec case/380W PSU, there is a 20 pin (!!) main power connector, a 6 pin AUX connector and a 4 pin ATX12V connector. HELP! These don't seem to match up. Any ideas? Do I need a different PSU? Or is there an adaptor available.. Dave | ||||||||||||||||

Please log in for more thread options I just got an Asus A8N SLI-Deluxe... it also has the new EATX 24-pin plug with the additional 4-pin connector.. I buckled down and got a 510W SLI P/S from PC Power and Cooling.. It has an adaptor BACK to 20-pin, but I am pretty sure you can't hook up an old ATX P/S to a 24-pin board. Another excellent supply is the 480W NeoPower from Antec.. it has connectors for both 24-pin and 20-pin boards. Good Luck | ||||||||||||||||

I've emailed Antec to double check, and I'm also just comparing connector pin-outs, but I think it's ok. See http://forums.pcper.com/showthread.php?t=376129 Anyone else tried this?

20 pin pugs do fit into 24pin plugs. My new MB cam with a sticker over the last 4 pins. It's says to remove the sticker if the power supply has 24 pin plug. cheers Kevin >

more info.. http://www.tomshardware.com/howto/20041223/atx12v-24pin-01.html "The reverse combination is also possible, as the 20-pin plugs fit into the big connector too. " Dave | ||||||||||||||||
