Akasa Introduces Power Xtreme 1200W PSU

Akasa adds its entry to the range of heavy-duty power-supplies with its PowerXtreme 1200W (model: AK-P120FG-BK). This 150x160x86 mm PSU features six independent +12V rails and a rated efficiency of 80 per cent. Apart from the usual plethora of connectors PSUs of this range are expected to have, it features two 8-pin auxiliary power connectors for multi-CPU socket desktop and workstation boards. It features a total of nine 6-pin PCI-E power connectors with six of them capable of doing 8-pin with a side 2-pin expansion that's detachable. Akasa provides a cable-management kit in the package, no modularity was advertised. The power distribution diagram is provided below. The PSU is priced at £189.95 or €240 (excl. VAT).

Why do they make 6+ +12v rails? I thought a single rail was better for multiple card setups..

With 28A rails it shouldn't be a problem. If you distributed the load evenly across rails, multiple rail PSUs aren't really any less competitive.

To my knowledge, there still isn't a device that requires > 28A. Usually these multi-rail behemoths distribute their connectors across these rails. Note how the first two +12V rails are 20A. These rails usually are the ones that supply 12V phases to the motherboard, and maybe the Molex/Floppy and SATA connectors. Rails 3, 4, and 5 are 28A and the PCI-E connectors care likely the ones split across this. I predict in this fashion: Of the total 9 PCI-E connectors, 6 of them are 6+2pin. Each rail holds two of these at ~ 14A each connector. The remaining 3x 6pin (6 only-pin) connectors could have two of them sharing the last 20A rail and one 6-pin with either the 1st or 2nd 20A rail. Without any gfx card, 40A is a LOT of power for the system, even with dual-Yorkfield's installed + a 6-member RAID + brutal OC.

Now back to "why no epic single rail?" ....simple, it's expensive to manufacture a single strong rail, strong rails are unstable at times. But companies like Seasonic and TOPower have perfected the art, Seasonic makes a 40A rail circuitry that's used in the Corsair HX1000W (two 40A rails). So it makes sense with these 20A rails. Those rails with zero load turn off (unverified). Also it becomes easy to distribute power with these multiple rails, imagine four PCI-E connectors sharing a 40A rail.
