Ultra X-Pro & X-Finity 800watt Power Supplies
 

Today's technology requires more power than ever, so this is where Ultra's X-Finity and X-Pro come in, with a monstrous 800 watts. Both are extremely heavy, with dual 80MM fans and AST technology, which continues to power your fans at a low speed even after turning off your computer - a nice feature! Both the X-Finity and X-Pro are just about identical, with the X-Finity being black and having unique Flex-Force cabling and the X-Pro, silver, with sleeved cables. Even better, they're both brushed aluminium!
