Thermaltake has a new top of the line PSU out, the ToughPower Grand 1200W Modular 80+ Gold PSU.  As you can see below, all but the motherboard connectors are modular, which is not going to be a problem for anyone with a cable management fetish.  There are eight 6+2 PCIe connectors for multi-GPU users and a dozen SATA connectors for the storage guru, with dual +12V rails which are 40 amp and 80 amp respectively.  Bjorn3D's testing revealed a few flaws which hurt their opinion of the PSU, especially when they factored in the high price of this unit.  The biggest flaw was the PSU's vulnerability to shorting out if long screws were used to mount it.

"Today, we will be taking a look at Thermaltake's flagship 80Plus Gold Certified ToughPower Grand 1200W Modular Power Supply. While this power supply is designed for overclockers and gamers that use multi-GPU setups, it is not 100% modular. This usually is not a problem with users that run high-end gaming hardware, but it might be a bit frustrating for those that just want to have a powerful PSU for the future but might not be running high-end hardware at first. For instance, its double 8-pin CPU power connector is hard wired into the power supply. Only a very limited number of motherboards support dual 8-pin power connectors, and this type of setup is only necessary for extreme overclockers for extra stability."

The Enermax MAXREVO 1350W PSU missed getting an 80+ Platinum rating by 1%, which puts it in rare company, kilowatt class or not.  Not only that, but in RealWorldLabs' testing it produced under 40dB under load which is impressively quiet for a 1350W PSU.  With 112 amps available to the six 12V rails and eight PCI-Express connectors ensure support for whatever multi-GPU monster you envision building.  All of that quality and those features do mean a higher price, $300 is the entry fee for this PSU.  It is worth it if you need it.

"The latest MAXREVO 1350W 80Plus Gold certified power supply unit by Enermax is not only a worthy successor to their already excellent Revolution85+ series but also one of the two most powerful all-modular units in the market with support for future power connectors, right next to its 1500W brother."

It is rather impressive that Enermax has managed to make a 1350W PSU that does not require a 240V plug, thanks to their FMQ transformer and use of copper interconnects instead of wires which Enermax refers to as a Copper-Bridge Array.  They've gone a different way from previous models and their competitors, splitting the 12V rail into six 30A rails which will still ensure multiple GPU systems can perform stably. Drop by [H]ard|OCP to see if this PSU can live up to its advertised power levels.

"Enermax has long been a favorite of ours when it comes to power supplies for heavy hitter enthusiasts pushing huge system wattage loads. Today it is launching a new flagship product that comes to up touting a huge 1350 watt usage rating. Does Enermax continue its top shelf legacy?"
