alternative to XFX 650 modular PSU?

[almoststew1990]

I have ordered the XFX 650W "XXX Edition Modular '80 Plus Bronze' Power Supply" but it has been out of stock for a while now, so I am considering getting an alternative instead. What is around the same price and quality? I've eyed the OCZ ZT 650W modular @ £70 (bit cheaper) and the Akasa Venom 750w Modular @ £78 (bit more expensive). Any other suggestions? Powering an i7 860 @3.7GHz, 7870, 2x 2GB DDR3 1600MHz, 2 HDDs and 5 fans.
