PSU sweet spot

[OcSurfer]

Hey guys,
looking at getting a PSU for either 2 670's or 2 7970's
looking to mildly overclock them and the cpu, which is a 3570k, probs be about the 4.5ghz range.just wondering 750w or be safer and go 850w?
will probbably be a silverstone strider gold just for ease of sleeving!

I found a Corsair 750W for A$159 and an 850W for A$179 so for $20 i'd go the 850 - in case you ever want to add something more to the rig.

NB: Corsair TX-750M and TX-850M (Bronze).

Go for 850W mate, just to be safe

A Corsair AX 750 would be more than enough but as the guys above have said for the extra $20 you might aswell go for the 850 dude im running my rig on a 750 at the momment with

i5 3570k
8GB of corsair red vengance
Asrock Z77 fatality professional-m
EVGA GeForce GTX 670

It runs it without issues and quite a bit of power to spare so you could easily get away with either 2x 670's or 2x 7970's

750 would be enough for the 670s. Depends how hard you over lock, but I'd probably try for an 850 if possible.

Definitely go for a high quality fully modular psu though, even if that means getting a 750 instead of an 850

Yeah as i said previously getting a silverstone strider gold so not skimping on quality at all

You could run that setup with a 650w. A 750w is all you really need.

^As above a 750w would be fine, and tbh a 650 would most likely work but personally I would go for an 850w

The 750W goes to 850W when needed with no probs James
