    After replacing the p/s the first time i thought id be set for a while, 7 months later and its dead. I've had power supplies last decades so this is completely unacceptable. good news is its still under warranty now if there is another choice :/

    Worst purchase ever

    After purchasing, realized I made a huge mistake. Did some research on this specific PSU, to find out that its really only rated for 200w-300w. Which is only sufficient for a really older machine. Which means no multi core, no updated graphics card, nothing. While reading up on this PSU, I found the reason for the much lower rating is its shoddy components. Using under a 300w load fries computer components. Subsequently returned. Don't buy this.

    Worst Purchase Ever

    Often times had to tap (sometimes quite hard) the power supply to get it to work. I will never buy this product again for it is too costly for a month's worth of use. It was the ONLY selection at the store at the time that supported the 24 pin motherboard. It wasn't worth having the power supply in hand when I could have had another in a few days time at 1/2 the cost.

    This was a second replacement for my Dell. The size of this PS was a bit bigger, but I got it to fit. I thought it was a great value when I first bought it, but it's only been six months and I've already smelled it burning, so now the fan barely moves. I'm replacing this with a Cooler Master PS.
