New Computer Build

[drumlegend]

So I don't want to spend more than £450 as I'm not rich

I have bought 4 new parts for my computer

Intel Core i5 3570K 3.4GHz Socket 1155 6MB Cache Retail Boxed Processor

Asus P8Z77-V LX Socket 1155 VGA DVI HDMI 8 Channel Audio ATX Motherboard

EVGA GTX 660 SuperClocked 2GB GDDR5 Dual DVI HDMI DisplayPort PCI-E

Creative Sound Blaster Audigy SE 7.1 Soundcard

The sound card isn't that good but it's more so I can have people voice audio coming through headset and game audio coming out of speakers.

I assume a 750watt power supply would be sufficient enough as well?

Any thoughts on the build.

850 would be better. Give you a little room for future expansion.
I use the Corsair AX850. It's modular so you only use the wires you need. 27amps on the 12 volt rail and that's more than plenty. 85+ gold rating. It's a real work horse.
And the price has dropped since I got mine last month. CORSAIR Professional Series Gold AX850 (CMPSU-850AX) 850W ATX12V v2.31 / EPS12V v2.92 80 PLUS GOLD Certified Full Modular Active PFC Power Supply - Newegg.com

I will look into investing into one at some point but I can't afford another psu right now.
