About to add another r9 290x to my rig, but overlooked my psu :(

Currently using a Corsair CX750 which ofcourse has been fine for my current build, but I'm unsure if it will handle another 290x.

i7 4790k @4.7
2 hdd's (3 ssd)
msi r9 290x watercooled along with cpu using d5 pump.
No optical drive.

Would watercooled units draw less power due to having no fans on the gpu? Or is the difference minor.

Some reviews and forums seem to say it will be fine, others say no chance and 850w is minimum.

My other question regarding Corsair psu's, if I was to buy another Corsair unit, can I use the existing cables and just plug them into the new psu, rather than stripping most of the rig down to change the cables?

Any recommendations welcome, haven't got a massive budget so £150 is tops really.
 
Yes but only the GS/G2 range as they are manufactured by Superflower :)

You can't go wrong with XFX either, all their units are made by Seasonic ;)
 
Lol better safe than sorry, even so that's definitely more than enough lol.

As for longetivity I'd expect around 10 years where I'd be looking to buy a replacement anyway. Plus if I remember rightly the warranty is also 10 years ;)
 
The 850g2 works fine, this system pulls about 700 watts fully overclocked, but i guess with the 1300w you went for it gives you options for the future......trifire? (you know you want to :) )

I certainly want to, although spending best park of £1000 on bits for the computer in the last few months are holding me back a bit! The cards can be had for less than £200 used, but its the waterblock and fittings that add on another £100 lol

Hopefully with the 1300w I'll never need to buy another psu! Just by chance it had red and black cables, which fit with my red and black colour scheme :)
