Just worried that the 450W power supply won't be enough? Let me know your thoughts, thanks in advance for any advice.
 
It should be fine but I would be phoning or posting the customer services section and asking how much it would cost to get the cpu changed to the 4970k in there higher base clock and turbo (4.4ghz) and better heat dissipation, if buying new no point in not buying the latest. if the 4970k is to expensive ask about the 4960k.

650w min I would say.

Same, will be a lot better for any future upgrades. AKA extra HDD's 2nd GPU. A 450W psu is pushing it for that setup imo, especially on the 12V rail/rails. Also bear in mind that a cheap PSU can sometimes put your other components at risk if the PSU fails (if from a cheap brand).

You guys do see that hes buying a prebuilt from overclockers dont you? If your worried ask custo.er services but i dont see why they put all the config options if the psu couldnt handle it?
 
If its a good quality PSU it "will" handle it but spending that kind of amount I'd want a bit more overhead personally and theres not not much margin for long term degradation of the PSU if you intend to run the system for awhile.
 
Thanks for the advice guys. I've rung customer services this morning and have asked to upgrade to a 750W unit. I might as well pay another £30 now rather than fork out at Christmas when I look for a SSD and better card.

Thanks again.
 
Anandtech had a power consumption of ~360W from that PSU and an overclocked i7-3960X, so your system should pull about 300W-350W. This is easily within the realms of a quality 450W PSU, and seeing as the OcUK machine comes with a SuperFlower 450W PSU, I would have no issues at all running this machine on that PSU.

It will be fine for stock speeds, and for a light to decent overclock on both CPU and GPU if you don't fiddle with voltages. If you are looking to set world overclock records, and/or heavily overvolt components then I'd be looking to upgrade the PSU, but for an average user I would say that PSU will be more than sufficient.

EDIT- sorry OP, my slow typing and interruptions mean you've replied and I didn't see it. Fair play upgrading the PSU if you are looking to upgrade the GPU at a later date, and provided it's a decent 750W (and from OcUK, it will be) an extra £30 does seem a good deal. :)

People are still massively over estimating how much power a pc needs. OCUK would not sell a prebuilt pc with a underpowered psu. The rig in my siggy only pulls 290-334w at the wall while gaming. I can make it pull just over 400w but only by running Linx and Furmark both at the same time. In real usage you will never put that much load on a pc.

Agreed. My little PC for LAN gaming runs an i7-2600K (at stock, H61 chipset unfortunately), AMD 7850 2GB, 8GB DDR3, DVD-drive, 240GB SSD, 2TB HDD and even a couple of LED strips ( :D ) and I was concerned the standard 250W PSU would really struggle. Hooked it up to a meter on the plug and found it was only pulling 190W-200W from the wall during heavy gaming at 1080p. After efficiency conversion this means the PSU is only supplying 160W-170W at most from it's rated 250W.

Really find it surprising how much power modern components can provide while sipping so little from the wall. :)
 
Always shocks me how much people overdo wattage requirements on PSUs. Yes, the advice is to not skimp on the PSU, but that is talking about quality not power output. 750W is massive overkill and will result in reduced efficiency as the PSU will be working at such a low load level all the time :(

Edit: Modern PSUs are actually very good at maintaining efficiency at low load levels, so it's much less of an issue than it used to be, but still :)

Edit2: My system has an over the top PSU too, just not nearly as far... cause I too am too much of a wuss to cut it fine!
