"There was a time, not too long ago, when a 1000 Watt power supply seemed like excess. However, with the recent advent of triple and quad graphics card systems, this once lofty capacity has become relatively common place. A quick visit to any of the myriad of PSU calculators available online and you may find your current system power demands now justify a 1000 Watt power supply.
No stranger to high capacity power supplies, Topower has been at the forefront of high performance power supplies in an OEM capacity for the likes of Tagan, ePower, Mushkin and BFG since 1986. Today, we take a look at a product Topower markets directly, the PowerBird series of high capacity power supplies. There are two available capacities, a 900 Watt and an 1100 Watt version."
