Power connectors for 7970 Crossfire

[ginginho]

Hello. I have a 1110w PSU which has 2x 6-pin PCI-e connectors, 2x 4-pin molex and 2x SATA connectors free. I'd like to be able to power 2x XFX R7970 cards and I'd appreciate your thoughts on the options. As each 7970 requires 6 and 8-pin power connections, it looks like I have to use the available 6-pin connections on the PSU with one of these:

To supply the 8-pin PCI-e requirements. This leaves 2x molex and 2x SATA to provide the 6-pin power. Is it possible to use a SATA > molex connector like this:

And then use a 2x molex > 6-pin PCI-e connector (http://www.overclockers.co.uk/showproduct.php?prodid=CB-018-AK)?

Whilst my PSU has the power, I am unsure whether or not the above will provide sufficient power.

Any thoughts or alternative solutions appreciated

What is the make+model of the PSU?

Its a proprietary PSU inside an HP Workstation :S

It should work, but is a mess.

Whats the rated 12v amps on the PSU?

Thanks for your reply. I realise that any posible solution is going to be sub-optimal but I thought I'd check! Regards, the ampage - at the risk of interpretting this incorrectly:
