Just when we thought power supplies were shrinking, there are still a few AMD and NVIDIA GPUs that require a great deal of power to run in quad CrossFireX or SLI configurations. While there are quite a few 1200 watt monsters available, there are only a couple of power supplies capable of 1500 or greater watts. The Rosewill Hercules 1600 watt modular power supply cranks out the power for these kinds of systems.
The 80Plus Silver Certified efficient Rosewill Hercules 1600 provides a +12V1 rail at 110 amps and a +12V2 rail at 50 amps. It's interesting that the Amperage has been split but it helps accommodate today's elite motherboards that support quad GPU configurations. It's cooled by a 135mm PWM cooling fan to make sure the 85% efficient plant is nice and cool under load.
The Hercules 1600 ships in a silver case as part of the experience coupled with modular 16 PCI-E 6+2pin connectors, 16 x 5pin SATA connectors, 6 x 4pin Molex connectors, and 2 x 4pin floppy connectors (just in case). There are fixed cables that include the 20+4pin Main power connector, 8pin EPS12V connector, and 4+4pin ATX12V/EPS12v connector which comes in handy with dual 8pin connector motherboards.
Keep in mind the Hercules 1600 is big! It's longer than standard power supplies. This unit measures 5.9" wide, by 9.5" long, and 3.4" tall. So make sure your computer enclosure has a little extra space. The MSRP shipping price of this unit is $399.99 from online retailers making it very appealing among the 1300 to 1500 watt competition.
