I finally scrounged up some cash, and I'm planning on buying an XFX 8600GTS from Newegg.
Thing is, it requires a 6-pin PCIe power connector, and I've only got one 4-pin right now. Would it be possible for me to use the 4-pin I have, the two fan connector to 4-pin converter that comes with it, and just plug them in, with two of the pins un-used? Or would I need, or just be better to get a newer, stronger power supply? Right now I've got a 400w Antec SmartPower. So what do you say?
This is what you could use if you wanted to:http://www.newegg.com/Product/Product.aspx?Item=N82E16812201004
The GTS can run if you psu is 22amps. I run a GT and could run the GTS with the connector. My psu is 22amps.
