New PSU req

[jongeeone]

All my bits just turned up for a new build, which are as follows...

i5 3570k
ASrock z77 Extreme 4
8GB Corsair XMS3
OCZ Agility 3 120GB SSD
Antec 300
6950 2Gb

I thought a PSU i already had spare would be ok, but it only has 4 pin ATX 12v and not 8, so need a new one!

I'm getting confused, some are 2.2 or 2.3 compliant - yet my manual says ATX 12 V1. So unsure what to buy!

What would you recomend?

It's not even long enough for the Antec 300! This PSU is a OCZ Modstream 520w. The PSU in my i5 2500k system is a Coolermaster M520, but thats staying put.

Possibly, something with 2 x PCI-E would be ideal.
