Hi I started to build my new pc and I ran into bit of problem.
I currently have XFX ATI HD 4890 and I also have Thermaltake PurePower 500W for my PSU.
The problem is, I didn't realized that 4890 needs both 6 pin pci-e connector and 8 pin pci-e and my power supply has only one 6 pin pci-e outlet.
I couldn't refund my PSU because I bought it couple weeks ago, when they had huge sale on Thermaltake psu so I'm kind of stuck.
My graphic card came with 4 pin to 6 pin adapter (I think 6 pin connector is 6 pin pci-e connector) so what I thinking of doing is to buy 6 pin pci-e to 8 pin pci-e adapter seperately so I can have both 6 pin pci-e connector and 8 pci-e connector.
No affense but research shoulda been done a bit before you bought that card. Those cards are power hungry, as are most high end cards. So i think you should strongly consider getting atleast a 600watt psu to be safe. PSU's are the one thing u really cant afford to cheap out with on ur pc. Yes you could run an adaptor but id expect problems. I seriously think you should break the bank a bit and go atleast 600 watt.. just an opinion. Or take a chance and go with the convertors but you might end up spending the money and it stil might not work.
