We take a look at two high wattage power supplies from companies
known for their solid product lines; the Silverstone DA750 model
features a single 12v rail and is rated at 750W. The FSP Epsilon has
four 12v rails and combined offers up to 900W. We stress test these
units in a real world environment with the most power hungry vga cards
out there, two ATI HD 2900 XT in Crossfire.
