Hello:

I just built a new PC. After installing all of the parts, I left the side panel off the case and powered her up. I looked inside to verify all of the fans were running and they were. About four seconds later though, the machine shut down. Every time I power it up, it only runs for about ten seconds or so and then shuts down.

Unless I'm missunderstanding the manual for the motherboard, I'm pretty sure it says to only hook up the 24 pin power connector although it also has a 12 volt ATX power connector too. I was going to hook that power cable up too, but I can't find one from the power supply that fits. The plug from the PSU has two parts that are square and two parts that are shaped like houses. This is the same for the connector on the MB, but the squares are where the houses should be and the houses are where the squares should be. I know that description of houses and squars sounds strange, but if you've ever built a machine before, you'll probably know exactly what I'm talking about.

So, what do you think? Do I need the 24 pin connector AND the 12 volt connector?

MB is ASUS M2N-SLI Deluxe AM2 NVIDIA nForce 570 SLI MCP ATX AMD.
PSU is Rosewill RP550V2-D-SL-S ATX12V v2.01 550W Power Supply.

Thanks,

Magus

the 24-pin connector and the 12v connector are needed to power the board and CPU.

Thanks for the reply.

Are there any other versions of that 12v plug. I'd like to think it's standardized, but I'm telling you...I couldn't get it to plug into the motherboard. It looked like the cable was made backward or something.

I'm at work right now, but will have another look when I get home.

At the very least, I know I have to have a line to the 12v connector.

Thanks for your help.

Hello to you both...

I did get the power running on that new system, got Windows installed, and everything looks good now.

At the end of the power cable I was talking about in my initial post, there were two plugs with four prongs each. One of them didn't fit but the other one did. I just assumed they were same when I was first hooking it all up.

Thanks for you help.
