 The FireStorm gaming power supply is available in 750 watt and 1050 watt varieties.A feature of PC Power and Cooling units is that their units use a lone, high-current +12 V rail for DC output to the rest of the system, as opposed to multiple lower current rails that run in parallel.This single-rail configuration is reminiscent of high-end power supplies in the early to mid 2000s, before an industry shift towards using split +12V rails for reliability, stability, and economical reasons.
