Now my question is it says it comes with one 6/8 pin PCI-E power connector, so does that mean I CANNOT buy a Radeon 4890? Shown here:

I have a Radeon 4850HD now. Thanks

By specifications, that is an excessively mediocre power supply. 44 amps is excessively weak for a 750 Watt PSU. A good 750 watt PSU will put out around 60 amps on the 12 volt output. And a 750 watt Corsair will have four 6/8 plugs.

Having said that, you can use a moles to PCI-e power adapter. The graphics card should have at least one packed with it.

for the 2nd PCI-E?

I just want one graphics card, but usually most of the new cards require 2 6 pin PCI-E adapters, so why I was asking, so I can use the regular 6 pin pci-e that my PSU supplies and then a 6pin to molex adapter? For the newer cards? Such as the 4890 if I wanted it correct?

ok cool thanks a lot
