I need a good powersupply which is for my budget of £100 can stretch to £110 but the main problem is that I need to buy it on Dabs.co.uk as I have a voucher for that website. Thanks in advance for any of the suggestions you make.

My current specs, I'm not going to SLI no matter what as when the time comes I need to SLI I might aswell buy a completely new GPU and sell my old one. However I would like to OC

i5 3570k
MSI GTX 670 PE
Asus P8Z77-V
CM Storm Trooper
Optical drive
Intel 330 SSD
WD 2TB HDD
Corsair Vengeance Ram.

What are the specs of you're computer?

Chances are you only need to spend half that on a PSU and the rest on another component.

1. XFX Core 550W: http://www.dabs.com/products/xfx-550-watt-core-edition-...

2. Antec HCG 520: http://www.dabs.com/products/antec-520w-high-current-ga...

Either of those PSUs is electrically sufficient for your build and significant overclocking. I'd go for the XFX because it has a little bit more power available on the 12V rail.

If you want to SLI that GTX 670, then you need a bit more power.

2. Corsair TX750: http://www.dabs.com/products/corsair-750w-cx-builder-se...
The 650W is powerful enough and the XFX is one of the few PSUs under 700W that has enough PCIe power cables so that you don't have to use molex adapters. Not to mention that they do it at a reasonable price.

Great PSU; and sufficient for an SLI of the GTX670 if you want go that route in the future. I guess there's no way to get the rest of the money if you buy a less expensive PSU? You could get a Razer gaming mouse and one of the other PSUs...there are penty of other accessories to drop 50 quid on....

So which one should I get the AX650 or the HX650, the reason why I'm spending a bit more is to know I can save a bit more on my electricity and I've already gotten my peripherals and everything. People also always say to never cheap out on the PSU and get one of the big brands e.g. OCZ, Corsair, Bequiet!, etc.

The AX650 is their best PSU so if it's in the budget then that is Corsair's best. The efficiency difference between the two is not significant. The electrical cost difference to an individual is not significant between an 80+ Bronze and 80+ Gold PSU. Those efficiency standards make more of a difference when you are dealing with large amounts of computers in an enterprise environment. The above PSUs that I recommended are high-quality PSUs so they wouldn't be 'cheaping out.'

Corsair have recently released a new model of the HX650, which is being marketed as 80 Plus Gold certified, it isn't on Ecova's website yet, but probably will be before long.
Unlike the 750W+ versions it is still built by Seasonic.
It's a step up in terms of efficiency over the original HX650, but only has two PCIe connectors.
It is semi-fanless like the AX series. Has a larger, but probably slightly lower quality fan.
Annoyingly, Corsair list the dimensions for all the new HX series as 150x86x200, but the 750W+ units are in fact 180mm long like the originals, the 650W might be 180mm like the rest of the new ones, or it could be 150mm long like the original?

TBH I don't think either one is worth £5 more than the other.
