Will this PSU be sufficient?

[Scott Buchanan]

Hi all,

I'm building a Mini-ITX little dude for gaming (LAN parties!), and these are the components so far. They're very much subject to change as prices fluctuate:

CPU: Intel Core i5-3570K 3.4GHz Quad-Core Processor (£166.79 @ Aria PC)
CPU Cooler: Corsair H60 54.0 CFM Liquid CPU Cooler (£54.99 @ Dabs)
Motherboard: ASRock Z68M-ITX/HT Mini ITX LGA1155 Motherboard (£87.47 @ Amazon UK)
Memory: Crucial 8GB (2 x 4GB) DDR3-1600 Memory (£32.70 @ Dabs)
Storage: Samsung 840 Series 120GB 2.5" Solid State Disk (£74.99 @ Ebuyer)
Video Card: XFX Radeon HD 7870 2GB Video Card (£166.07 @ Aria PC)
Case: BitFenix Prodigy (Orange) Mini ITX Tower Case (£62.27 @ Amazon UK)
Case Fan: BitFenix Spectre 97.8 CFM 230mm Fan (£12.90 @ Amazon UK)
Case Fan: Arctic Cooling Arctic F14 77.3 CFM 140mm Fan (£7.99 @ Novatech)
Power Supply: Antec High Current Gamer 400W 80 PLUS Bronze Certified ATX12V / EPS12V Power Supply (£47.25 @ Amazon UK)
Total: £722.92

I'm open to suggestions of any kind, though I'm definitely keeping the price ~£700 +/- £30, but what I am most concerned about is the power supply. I know, for sure, that I'll be cutting it close on the wattage here but I think it'll all run okay. Do you think I'm taking too much of a risk?

Bear in mind: I am not likely to ever upgrade this build with new components but I may overclock the CPU / GPU a bit as needed. I rarely upgrade at all, I do a build every few years and then sell it on to finance the next one . This power supply was the highest quality I found while maintaining a manageable price.

Thanks in advance!

i think you are pushing it. I would go 500w for the peace of mind.

Corsair CMPSU-500CXV2UK Builder Series CX500V2 - 80 Plus Certified Power Supply - £49.50

While I agree that minimum 500W would be better, the CX series is not the greatest power supply you could purchase. This would be better: http://www.overclockers.co.uk/showproduct.php?prodid=CA-030-SS&groupid=701&catid=123&subcat=2383

I also think I would drop the H60 for something like a Noctua NH-U9B instead but that's my opinion.

Thanks alot fellas.

From this feedback I will almost certainly go for a 500w but unfortunately the one g-unit suggests is more than I'm willing to spend. I'll start with the CX500V2 and shop around from there.

EDIT: What do you think of http://www.amazon.co.uk/dp/B004RJ8EKI/?tag=pcp0f-21

G-unit, I actually only went with the H60 because I couldn't find a decent air cooler that would fit along with the GPU on the small mini-itx motherboard, but that one looks like it would! The more I've read recently about the H60 though the more I've liked it, why would you rather I go with the Noctua?

I personally would go with the strongest air cooler over the weakest liquid cooler. There's really nothing that says that closed blocks like the H60 are better than the air cooler I typically recommend. If you're going to do liquid cooling use the real thing or don't use it at all.
