Just got Antec KS282 .... now I can't boot!!!! Help!

[zeppelin]

I got the ks282 today. All I did was replace the case, everything else stayed the same. When I go to power up ... the fans start for half a second .. and then everything goes dead. Nothing.
Possibilities: Did something happen to the MOBO in transit? Can my mobo not handle a 300Watt PS (previously it was a 250W Case)?
Any thoughts would be appreciated.

*I've tried reseting the CMOS ... no luck

Most likely cause is the mobo is touching the case and shorting out. Take a look and see if you can see anything that would short out. Remove the devices and reset the mobo. Just add the video card and boot up. See if you can get past the bios. If this works, you've fixed the problem.

This is what I found out:
I put my other computer beside the dysfunctional one. I removed the power supply ribbon from the working case and plugged it into the non-working case(this is probably not so smart). I turn the power on ... it boots.
Now, can I unequivically say that I have a faulty PS? The working one is a 250W PS and the ks282 is a 300W. A 300W should work, right? It's anAopen ax6bc ez mobo running a 633MHz celeron.
If this is the case, can I call Antec and have them replace the PS rather than returning the entire case?
Thanks

check the back of the 300w ps...and make sure it's at 115v mode not 230v mode...
