Ok so I am getting a new GPU that requires a "450w PSU with at least one 75w 6 pin pci-e connector" and my current 460w cooler master has that 6 pin pci-e connector, but how do I know if it has 75w?
Also would an ati radeon 5770 run on a 460w cooler master?
what is the model number of the cooler master psu? what is the ampere rating on the +12v rail of the psu? what are the rest of your system specs? the ampere rating on the +12v is important because modern pc components (cpu, gfx card etc) use that rail the most.
theoratically, a 460w psu should run a radeon hd 5770 but it's wattage is pretty close to minimum requirement recommended by the manufacturer.
