  1. Use the link below to determine how much power you need then buy a Seasonic X-series or PCP Power and Cooling PSU.

  2. either your house has bad power or you have bad luck but the alpine had plenty of wattage. so your system didnt stress it all that much. either it was bad or your power was bad. im only worried about bad power cuz you have had two die.
    what do you plug your power supply into? surge strip, UPS, etc.
    supposedly an active PFC power supply gets destroyed by the type of current coming out of a UPS. but i know lots of people that have had no such problems, including myself.

    but for advice "pc power and cooling" used to make the absolute best power supplies, they were bought by OCZ but they still seem to be damn good.
    im using a Rosewill right now and its voltages are spot on, had zero problems with it. corsair, antec, and coolermaster are all great brands. but every company has its lemons. check reviews.

    best place for reviews newegg.com and also my favorite place to shop
