Where can I get cheap PCIe X16 extenders with molex?

[kujayhawk]

Can anyone help me find where can I get cheap PCIe X16 extenders with molex?

I know of a supplier on ebay that sells those (calesaurus) but the prices are more than I want to pay. I'm tempted to make them myself however I'd rather buy them premade. I wanted to PM haploid23 to see if he still makes those but I'm new to this forum and I think I'm restricted.

I bought one X16 extender with molex and connected the molex to a second power supply and measured the wattage to be drawing about 30 watts. I don't think that's much but I don't want to overload the board. I plan on having four or five HD 7970s on this board. Does anyone know how many watts goes into a x58 motherboard that has an 8-pin connector on the board?

Thanks!
