Having problems with your OEM Systems Xion / 400-Watt / ATX / 80mm Fan / Power Supply (OEM) (XON400X) ?

I have a power supply that is turning itself off immediately after switching it on it is a new motherboard as well Any ideas why ?

Answers :

I think either the MB or the CPU is with problems.

Try (2 after 1 works, 3 after 2 works...):
1) only PSU+MB+CPU and Fan - works? beeps like crazy?
2) add memory - works? single beep?
3) add/connect video - any image?

All other connectors off (disks, etc) only PSU, fan and case buttons.

If you don't get past 1), go back to the store and have it tested/returned there.
