Hey guys, I got an hd5770, and a 450w PSU. The PSU has a couple 6-pin ports on it (including one saying it's dedicated to pcie) and the card also has a 6-pin connection. Problem is I don't have a 6-pin to 6-pin cable, so for now I've got it hooked up by using the 6-pin to 2x4-pin cable that came with the card, and plugging each of those into a cable that has 6-pins on one end, and splits into 4 4-pin connections, so 2 are used for the hd5770, one for one of my HDDs and it all gets fed into a single port in the PSU.
My question is does this feed enough power to the gfx card? Does each port in the PSU have a limit to the amount of wattage it can output (in which case using the dedicated port is the best option) or does it not matter?

The 5770 doesn't output enough power to cause malfunction, so yes your good.
