I ordered a power supply from ATX Power Supplies, and installed it. It worked beautifully for precisely 30 days (which says to me I installed it properly), which coincidentally is the period during which they will accept returns. After precisely 30 days (no kidding, 30 days exactly after I placed my order), it exploded. It didn't stop working, it exploded. Pop- Fire- Explosion. In my bedroom. I'm glad I was home at the time.
I was told I couldn't return it beyond the 30 day mark, but could exchange it, plus pay them a 20% restocking fee. This is not a valid option, as theres no way I'd buy another power supply from a company that sent me one that exploded. My previous power supply of the exact same model lasted 4 years and didn't explode when it died.
