I don't see why not, so long as your PSU can supply enough juice (and at 750W, it should).

See the motherboard manual, Chapter 5 section 5.2 NVidia SLI Technology, for details on how to set it up.

My PSU has only got one 6-pin cable, would using a molex to 6-pin adapter cable work?, i read that the dedicated 6-pin PCIe cable take the load away from the molex cables, which are designed to power drives etc, personally i think that is the not the case. Would the molex cable with the connected molex to 6-pin adapter use the same power as the single 6-pin cable?.

Using a Molex-to-PCI-E adapter is probably OK.

If you can connect to Molex connectors on different cables, that may be best.

Getting a better PSU would be nice. The one that you list is rated at 20A on each of its two +12V rails, which isn't outstanding for a "750W" supply.

I wonder how much power two Palit GTX 550 Ti's would draw from my 750watt PSU. What do you reckon?.

According to this:

The Truth About Graphics Power Requirements V2 - Atomic 3.0

a single 550ti maxes out at 152W. A pair would be over 300W, or 25A at +12V.

Of the PSUs that you list, I like this one the best:

Corsair CMPSU-850TXV2UK Enthusiast Series TX850 V2 High Performance 850W Power Supply: Amazon.co.uk: Computers & Accessories

I would have suggested the 750W unit, but the price difference is small enough that I recommend the 850.

Do you think that my PSU would handle it then?.
