PSU Fried - Brand new HTPC

I recently built my HTPC. Not the first I have built and have been building for years. The PC was running great for 2 weeks. And then the other morning I came downstairs and the case power led was off. The lights on the PSU were on. I thought this was odd. I hit the case power button and nothing. I decided lets shut the PSU power off...which I did. I then turned the PSU back on and the power lights to the PSU came back on. I then hit the power button on the case and I heard the dreaded *POP* followed by the amazing smell off electrical burn. The PSU was fried, the burn odor definitely was coming from it.

I have several concerns at this point.

1. No vendor, not the PSU, not the reseller will warrenty me when this hardware is no more than 2 weeks old. What are my options? The reseller is Newegg whose customer support is typically great. But I have real concerns here based on this problem. They have warrentied my PSU which is fine and all but what if the PSU fried everything else? Am I out my 1000$ brand new htpc that I just built due to a faulty PSU?

2. What are the odd's the motherboard caused the PSU to fry? I am very concerned that when I hook my new PSU up to the system board, if the board was the root cause, it will pop this PSU as well. (Obviously I will have nothing else connected to it on initial reinstall)

I am very frustrated and concerned at this point that due to a faulty peice of hardware I am about to get burned out of my hard earned money. I figured I would come to the experts here for some good solid advice.

Here are the specs for my HTPC:

Silverstone GD01S-R ATX Case
Silverstone ST45NF 450w PSU
WD Caviar Green WD10EADS 1TB HDD
Sony optiarc 24X DVD/CD RW
AMD Phenom II X3 710 2.6Ghz
MSI DKA790GX Motherboard
Hauppauge WinTV-HVR-2250
Patriot Viper 4GB DDR2 1066 (2x2gb)


Thank you in advance for any help or advice anyone can lend.

You really cannot say that (well, yes you can, but you could be wrong. There's no way of knowing that a PSU took out none, one, or more components when it failed without testing every component.

A well designed PSU is supposed to electronically shutdown during overload or overvolt conditions. But one it fails, all bets are off.

Surprising the PSU blew out, Silverstone are a reputable gang of PSU makers. I'd get in touch with Silverstone and see what their RMA service is like. You could have gotten an unluckily faulty model.
