Back in January of aught seven, the founder of this very site pitted two of the biggest and baddest against each other to see which of them rose to the top. Those two power supplies were the newly released Silverstone OP1000 and the PC Power and Cooling Turbocool 1kW.
Well, times have changed since then and the competition has gotten tougher. Silverstone opted to deal with it by revamping their unit using a different OEM. The new revision is called the OP1000-E, and I've got my hands on one right now.
