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?

6-pin connectors ARE 75W connectors.

Yes it will.

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.

All 6 pin pci-e power connectors are supposed to be capable of 75w.

Your psu is ok if it can deliver advertised power.

Go ahead and use it.

But, be aware that cooler master is not considered a high quality psu.
