Rosewill Announces 1600W Hercules PSU

Rosewill recently took the wraps off of a monster of a power supply that is rated to deliver 1600W of power. The Hercules 1600W PSU is an 80+ Silver design that will provide efficient power for quad CrossFire X or Nvidia SLI multi-GPU setups. It measures 5.9” x 3.4” x 9.5” and should fit within most full ATX cases without issue.

Other features include sleeved cabling and a 135mm “silent” fan that has an automatically adjusting RPM setting as well as a Turbo button that will spin the fan up to its maximum speed.

Where the PSU really stands out though is in the sheer wattage and number of PCI-E power cables. It features two 12 volt rails at 110A and 50A each. Rosewill has divided the rails such that 12V1 handles all of the PCI-E power connectors (up to 1320W) and the 12V2 rail rated at a maximum of 600W and is used for all the other 12V connections.

The included power cables are as follows:

  • 16 x 6+2 pin PCI-E
  • 16 x SATA power
  • 6 x 4 pin molex
  • 2 x 4 pin floppy power
  • 1 x 8 pin EPS
  • 1 x 4+4 pin EPS
  • 1 x 24 pin ATX

Needless to say, it has an impressive number of power cables. You might have a hard time finding enough graphics cards to use even half of the PCI-E power cables, for example. Fortunately, it has a semi-modular design (the ATX and CPU power cables are non-removable) so that you will not have to find enough room to hide all of the excess cables in the 5.25” bays (heh).

The 1600W Hercules power supply is available now with a price of $399 USD. While it will be overkill for most computers, it is impressive nonetheless and would be well suited to powering a rig with dual Powercolor Devil 13 7990 GPUs.
