SilverStone will soon start shipping the Zeus ZM1350, a new 80Plus Silver power supply rated at 1350W continuous. The unit is capable of handling a peak power output of 1500W and features a fully modular cable design. It has Active PFC, six +12V rails with a single rail mode, and a MTBF of 100,000 hours.
Interestingly, the power supply is cooled by a single 80mm fan. We'll have to wait for reviews to be sure, but such a small fan on such a powerful power supply likely means you can expect a lot of noise if you're really going to stress it.
