I just got this supply I have it all setup and seems like a nice cheap supply for the money and very tidy. I just have two things I wonder about firstly it has two PCI-E connections, at the moment im on budget so was thinking about buying an ati 4770 or maybe even lower a 4670 now if I want to buy a second card in the future do you think it will run 2x of these? Also a small thing the supply is very quiet most of the time but at certain loads it makes a small screaming noise thats not very loud (you can only just hear it) but I just wonderd if anyone knew what that was?
