PC Power & Cooling has designed the Turbo-Cool 1200 for optimum power distribution to all components by utilizing their customary "single +12V rail" design. This trail-blazing approach to +12V rail design ends the need to budget power "across the rails" as is the case with the less effective multi-rail design found in the vast majority of high-performance PSUs on the market today.
The PSU is dubbed Turbo-Cool, and while 1200W is still a huge amount for even a power rig, a high efficiency rating and the prevalence of high power GPUs makes it attractive. The $500 price tag is pretty steep, however most high-end PSUs are in that realm. You can read more about the PSU at the product page n the PCP&C site.
OCZ acquired PC Power & Cooling earlier this year.
