Woops blown my Enermax PSU

[Bill H]

Hello;

ASUS A7N8X Deluxe and Enermax 350W PSU.

The missus switched on the PC and said that it immediately immited a loud
bang.

I checked it out and when the UPS is switched on it fails.

Removed the UPS and connected straight into the PSU with a new connector,
another bang!!

Removed the PSU and took it apart no obvious burnt out components, change
the fuse in the power connector and switched back on..........fireworks came
early this year!!!

I tried out a spare PSU that I had in the garage but the system case would
not power up dead as a Dodo, problem is not sure the PSU was working anyway?
Tried to test the PSU on its own from info off the web (Connect the green
wire to any common and switch on) Nothing happened, so PSU might be duff.

Well I now have a dilema, I know I need a PSU so I'll have to get one but
what are the chances of the Mobo being fried??
Tried an Ohm test on the power connectors on the HD's and CDRom and no
obvious shorts but how can I test the Mobo (Again no obvious damage)

If the Mobo is damaged what are the chances of a damage Mobo blowing a new
PSU??

Last note when I took the Enermax apart the internal fuse was intact?

Any help would be great. Need a PSU in a hurry only shop open tommorow is PC
World and think they only sell JeanTech.

Regards

Thanks for all the help,
As I needed to fix it today after carrying out some more tests, Ohm Test on
Mobo Power Socket, I popped down to PC World this morning (Only place open
on a Sunday).

PC World only sell Jantech and one Hipper (£69.99) I had already checked the
specs on the Net, needed a 450W to be sure but low and behold they only had
the Jeantech 400W (£39.99) & 600W (£69.99).
After a bit of a discussion with the promise of it it don't work or blows up
cos you have a faulty Mobo bring it back and we'll refund you I took it the
Jeantech 400W JNP-400P.

The power rating seemed OK, but having two +12v ratings confused me
slightly.

+5V 35A
+3.3V 28A
+12V1 15A
+12V2 17A

What are the two +12V.

Took it home connected it all up and voila my Neon Fan kicked in and the
machine started up and is working fine, tested it running Unreal Tournement
and all seemed OK.
Two zaps with a busted PSU and the Mobo survived.......phew
The Jeantech might not be the best but at least it works!! pretty quite too.

Many thanks

What are the two +12V.

One is the ATX12V power for the CPU.
The other is for the drives.
