Question is what power supply do i need?

SPECS:
8GB (2x4gb) Corsair DDR3 Vengeance

Intel core I5-3570k

Gigabyte GA-Z77-D3H

How about you give us a budget and we'll take it from there.

Will you be OC'ing?

Its around £700, excluding VAT (which is always a bonus)

I would like to OC it in the future and the 'K' is good for that if im correct?

I'd say ~ 620w. Get a quality PSU from Antec, Seasonic, XFX, Corsair or PC Power and Cooling, Silverstone. At least 80+ bronze quality.
Full list of good and bad psus here http://www.eggxpert.com/forums/thread/323050.aspx


would it cripple the PC if i get a 650w/700w PSU? because its always good to go a little over right?

I already included "little over" in that 620w but if that makes you feel safer you can go 650w. 700w is just too much and money spent irrationally.

A larger than needed PSU can be damaging, or just less efficient. If for instance

a PSU is best at 20% load and has received an 80+ certification of one degree or

another to guarantee that it delivers power good enough at this level, it won't help

your cause if you get a gigantic PSU. Such as 1300W, if you only use very little. Because

then you'll be using below this 20%, where there's no guarantee it will work and thus

it's better to pick more appropriate PSUs. This build is SLI capable and is quite good.

Dude, awesome build thank you so much! :D 

Just one little thing could the AMD processor be changed to an intel one? a couple of my mates have had problems with AMD, not fully understood what but its steered me away from them a little bit

Well I'd argue it's the same as with other brands. Some people swear by WD

HDDs and some stay far away from Seagate HDDs. There's nothing wrong with AMD

per-se. You still get a lot of juice and usually more overclocking. They're cheaper too,

hence they often fit into budget builds as well. Nonetheless:

To not blow the budget completely, I couldn't put in an SLI ready motherboard.

Instead it's only CF ready and consequently I put in a Radeon card... Which is also

made by AMD, so you might not be happy about that. It's said they don't run as well

as Nvidia cards, when it comes to their multi-GPU configurations (CF), but recent driver

releases suggest they've gotten better. The good thing about this GPU, is that you get

some free games too. The PSU also had to be lowered due to the budget. Have to say I prefer

the other build. Eitherway it's some pretty good performance you're in for. I'll be the first to

say that the CPU isn't the newest in Intels lineup. It's one generation behind. But it's the

one which is best for overclocking, compared to the most recent generation. It's still a solid

CPU and the performance difference is nigh 10% or so. The 4th generation CPU (as opposed

to this 3rd gen one) was also more expensive and wasn't easy to accommodate in the build.

I also got the impression you wouldn't be OC'ing right away. Hence I didn't add an aftermarket

CPU cooler of any kind; thus you'll go with stock. I figured you could just buy it later, when

you actually intended to OC, seeing as OC'ing doesn't necessarily give a performance

boost; neither in speed nor in games. OC'ing generally makes things more expensive:

motherboard chipsets, adequate PSUs, K-edition SKUs and extra cooling equipment.
