personally i think all three choices are even. pick the one you like best. neither get amazing results on guru or hard ocp, but no serious issues either...
without meaning to complicate matters, what about xfx's 650w offering? http://www.scan.co.uk/products/650w...bronze-85-eff-sli-crossfire-eps-12v-135mm-fan
Just replaced my Antec 650W (admittedly with another one) but it only lasted me 13 months, so not as rock solid as reported. Waiting to see what Scan have to say when it's returned under the 60 month warranty. Wish I'd ordered through amazon the first time too, as their customer service is better that scan's in that they'd send an immediate replacement. Their price is a little higher on the unit (about £80) but they're selling 2 x 2GB of 1600MHz DDR3 at £37 at the moment too, so that was the sweetener that made me click buy!
How great? Can anyone else recommend it? I'm stuck on the PSU front as well now due to the fact the Antec Truepower has been hiked.
Review : http://www.hardwaresecrets.com/article/XFX-650-W-XXX-Edition-Power-Supply-Review/899/1 It's actually made by Seasonic What are you going to put into the rig? 650Watts may be overkill.
i have read a review in a custom pc mag i pulled out of my 54 i have and thay said the fan on that unit sounds like angrey beez lol
