@BobFrancis:

A 750Ti without a 6-Pin PCIe power plugs (like the EVGA GTX750Ti single fan) a single 120W external PSU with barrel plug should be just fine.

Great, I think that will fit my needs quite well, since I don't think I'm proficient enough to do the DA-2 setup.

Will purchase the following today:

EVGA 750TI single fan

Akitio

120W Adapter

When the parts arrive in a couple of week I will report back with the results!

@BobFrancis:

Since you might realise how easy that wires are they use, you can DIY very easy. Just get the same barrel plug with screw terminals and a 6-Pin extension or 6-pin y-cable.

Using two PSUs at the same time can result in ground loops damaging your setup! I don't see the point since you can see from the first section of my answer that it is no problema t all to make that barrel plug.

Thanks so much for your reply! I understand the concept of using the barrel plug with screw terminal, would you mind linking me exactly what the 6-pin extension cable should look like? I assume I would have to cut that and feed the cable into the barrel plug.

One final question. I travel quite often, so portability is a big bonus for me in this case vs power of the card. I have read through this thread but still can't work it out, would using the 120w DC adapter with the Akitio provide enough power for a 750ti, thus negating the need for an additional ATX/SFX PSU?

Just to be clear, aside from cost would there be anything wrong with using (Rockminer R BOX Power Cable 2 PK 12V PCI E TO 3X 5 5mm X 2 5mm DC Barrel Plugs | eBay) rather than the proposed molex to barrel adaptors? Although I have constructed PCs before, I am still a bit of a noob and not really comfortable making my own setup. Alternatively, nando suggested a couple of months ago that a generic 120w such as (AC Converter Adapter DC 12V 10A 120W Power Supply Charger DC 5 5mm FOR LED CCTV | eBay) could replace the standard, and thus provide the necessary 75w. If I don't mind having two power leads (including the SFX modular PSU I plan on buying), would there be anything wrong with using that instead? Many thanks in advance!
