New System Build Shuts off to quickly

I removed the GPU and there is no change in the system behavior, I timed the shutdown and it is 5 seconds not 10 to 15 seconds. I do not have another PSU.

Thanks

Is this a new problem - or has the computer never worked?

This is a new system that I built yesterday and acted like this on first power up.

The computer power stays on now.

Steadywaters suggest that I check out
http://www.tomshardware.com/forum/ [...] -problems. #2 CPU Power Connector, I notice no power going to the motherboard EATX12V connection or CPU Power Connector. I connected the power to the connections and the power stays on now.

I would say Asus manual is not very clear about the EATX12V connection or CPU Power Connector, not clear at all.

Everyone thank you fro helping me out in this problem, now I can press on setting up my new system, you'll made the day.

Thanks.

Your system will probably shut down once you start pushing the GPU on graphics-intensive applications (such as a game).

It's always best to follow the suggestions of the manufacturer - so pick up a solid 600+W PSU (Corsair, Antec, SeaSonic, XFX brands come to mind).

250w is only 25amps so I would try running your system first. As long as you use 6/8 pin connections from different rails you should be fine. I would try it before you buy a new one. If you want to know if it will work all the time, try running Furmark. It runs your GPU at maximum, so you will know if it works.
