R9 290x Crossfire Watercooled - PSU Recommendations

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.

Thanks I will take a look

Just browsing OCUK, are EVGA regarded as a decent brand? I'm out of touch with PSU's so don't know who to avoid.

Thanks, thinking about the 1000w EVGA G2 to give me some overhead, seems a bit of a minefield! Do you think the 850w will still be cutting it a bit fine?

Ended up ordering 1300w g2 evga. Was going for the 1000w, and for the sake of £25 got the 1300w so I hopefully never have to buy a psu again! lol

Thanks all for the help.

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
