'Okay, it's a power supply. Not much excitement there unless it starts smoking, right? But this one is so cool, it's smokin'! Like the 52 Ampere +12V rail (and there's just the one +12V rail, so you don't have to balance your power needs by hand.). How about the ability to auto-sense your input voltage from 90Vac to 264Vac, 50/60Hz? No more voltage selector switches!
Run cooler, too, because it can be up to 80% efficient (tested at 20%, 50% and full load), meaning less waste heat from the supply. Compatible with both ATX 2.0 and ATX 2.2 systems, it includes long cables for even full-sized tower installations. Nvidia SLI support. It includes power connections for eight SATA drives. A 120mm variable speed fan with double bearings gives good airflow with minimal noise. Active power factor correction helps deal with inductive loads (drive and fan motors, mostly).
Give your computer a power supply that can keep up with the times. '
