Newegg.com - KINGWIN 8" SATA Power Adapter Cable Model SAC-05 - Cables Welcome to TechIMO!

Thanks! However, I'm from the UK, so I'll have to look elsewhere for these adapters. Can I use just one adapter, plug the SATA PSU cable into the adapter and plug both molex's of the adapter into the GPU, or do I need to use one SATA cable for each molex port on the GPU (and therefore, buy two of these adapters)? i.e. do the two molex's on the GPU need to be fed into two ...

The number of adapters depends on 2 things, first dose the PS have more than 1 12v rail? Second, if it has more than 1 12v rail, is 1 rail big enough to run your video card by itself. As far as what connector the card uses, they are different plugs, and you should use what ever one it requires. If they make an adapter to get the power from it should work

Erh, I'm not sure if it has more than one 12V rail? It's a Zalman ZM460B-APS ATX12V Ver 2.2. I'm not even sure if it's powerful enough to run the GPU, although it seems to be okay. On the box of my PSU it says: ATX "20+4" -Pin Main Connector ATX12V CPU (4-Pin) Connectors EPS12V CPU (8-Pin) Connectors Dual PICE Express VGA Power Connectors (6-Pin) NMB-MAT 120mm Fan...

It has 2 rails, and just randomly choosing 2 plugs could get the same rail twice. Connecting 2 plugs to one rail will not increase your power to the video card. You have 1 rail @16 amps and the other @18amps, combined they put out 34amps Newegg.com - Computer Parts, PC Components, Laptop Computers, Digital Cameras and more!

So, I need to buy two separate SATA-to-molex adapters, but do the SATA drives run off the same rail? If so, I'll need to use one adapter for use with a SATA plug, and then use one from elsewhere? I'm confused as to which power cables are on which rails?

All the multi-rail PSs I have seen tell you what rail powers each plug, somewhere. Edit; Why can't you use the PCI-Express power connector?

Okay, I'll try and find it... I could use the PCI-E power connectors, but I'd still need a PCI-E (male, I think), to female molex adaptor... my graphics card is AGP, not PCI-E.
