Any quality 600W unit will be plenty powerful enough.
Have you still got your eye on the Corsair CX 600?
It's all good stuff. I'd go for it! :good:
^ check my edited response.
If you can, spend a tiny bit on your PSU and get this modular version of the CX 600 http://www.ebuyer.com/429985-corsair-cx-series-cx600m-atx-power-supply-cp-9020060-uk cuts down on the cables, making cable management easier.
But yeah, if you can - get that modular CX 600, then go for it.
New PC all put together. Very very fast. I managed to install 8GB of ram, the other 8GB wouldn't fit as the DH-14 wouldn't fit onto the CPU. So I'm gunna have to get ram that isn't too tall. Thanks a bunch though!!
Ahh crap sorry I didn't think about high-profile RAM and those huge coolers, sorry.
Yeah you'll have to get some low-profile RAM. There's low-profile Corsair Vengeance which is good RAM.
Really pleased you're impressed so far though - apart from the RAM.
