DragonSteelMods.com posted a review on the FSP Booster X5 450Watt Multi-GPU Power Supply
Today for review I've got a supplemental power supply from FSPGroup called the Booster X5, it's a 450 watt PSU that fits into a 5.25" bay of your case, it's made just for your video cards with four PCIE power connections built in. The idea behind this product is to give the user a little extra power for those newer, power hungry video cards, it's a great way to supplement your standard power supply if it can't handle it instead of going and buying an entire new power supply for your system.FSP Booster X5 450Watt Multi-GPU Power Supply Review
