Looking at getting a new PSU for my benching rig. Currently running a Corsair HX620w and its time to go bigger. I do understand that the psu isn't a place to skimp but I am on a shoe string budget at the moment.

So, will this Corsair AX850 handle the load of some Dice/LN2 action and a couple of GPUs in Crossfire/SLI without skipping a beat?

Or hould I step it up to this 1000w?

Or should I just save up for an overkill 1200w-1500W PSU?

Or, bear with me, should I run dual PSU's. 850w for Mobo/GPU's and 620w for all other aux stuff like, fans, pumps, hdds, ect...........

My brain is like a pretzel right now

Thanks,
