For the moment im stuck between

1:

2:

One of them comes with 8-pin PCIE connectors and the other comes with a 6-pin PCIE connector
In my system i have a AMD 965 BE Stock clock - CLUB 3D 6950 2GB - 4GB RAM .

1) Which one should i choose?
2) Are they good enough for my set-up?
3) I previously got a 650w and my graphics card wouldnt display on my screen but my onboard would?

Thanks guys and that's about it, if you need any further info and such let me know! I don't want the same problem as i had before.

you need to fix your links. If it was actually a 650W there's no reason a 6950 wouldn't run on one. I have also never seen a GPU the uses a single 8 pin connector. they all use 2 6 pin to get to 150W. why I don't know. A 6950 required 2 6 pin PCIe power connectors to work

well I can't see why the 650W failed, was it a cheapo one?

you could really get away with using a 500-600W PSU with that build, it would run fine!. The OCZ has 2x 6 pins and 2x 6+2 pin connectors which is fine for you.The Cooler Master has 4x 6+2 pins which is better for cable compatibility, but I doubt you will be upgrading to SLI 590s any time and making use of the extra 8 pin connectors. you could run Crossfire 6950s on either PSU!

if you want you could step the power down a notch and look at the smaller brother of the OCZ:

or an XFX one:

OK, I'll throw my hat into the ring.

I think that the Corsair Enthusiast Series TX 750W V2 High Performance '80 Plus Bronze' Power Supply trumps the other choices, IMO

The 650w was a cheapo one, it gave my onboard a monitor display but when i hooked it up to the 6950 i got no display on my monitor. So i (with some help) came to the conclusion of returning it and purchasing a new one.

And there we go. it was probably closer to 300W than 650W. the cooler master is also crap as usual

That system should run fine on an actual 500W PSU

XFX Core 550W: http://www.scan.co.uk/products/550w-psu-xfx-pro-series-...
More than enough for your PC and significant overhead for OC if you're interested. Made by Seasonic - awesome manufacturer, 5 yr warranty, rock solid rails, very quiet, and costs less than that TT "psu."

Yeah thanks, only thing im skeptical about is the fact it's a 550w wont that be cutting it close? Any other PSU recommendations for around the £60-£70 mark that will leave breathing room and put me at ease.
