Corsair TX850M - GTX 780 SLI

[SToneZ]

Will the corsair tx850m be enough to power 2x gtx 780

i am about to spend £1400 on upgrades and don't want to have to spend more and get a 1000w or a 1200w
so any advise would be great thanks.

So you want over 1200$(or pounds) of Gpus and spend as little as possible on a psu, when the psu could easily kill an entire system? Hmmm..

Anyway yes a TX 850 will do so. A 750 could also if not overclocked much. Try getting a slightly higher end PSU, that's the worst thing to skimp out on.
Try Seasonic/Corsair/Kingwin/Silverstone/XFX(only higher end ones).

im not skimping out on anything i am already spending a lot of money and i already have a tx850m so i would rather not but a new psu but what i might do is use the 850 for now then get a 1200 psu later.

Well it will do. If you live in the UK you will get better effeciency compared to say the US. So the bronze may perform slightly higher than it's rated at. 1200watt psu is only needed with quad gpus and crazy overclocks. Stick with what you got now.
