n00b_monkey · 24 Mar 2014 at 08:10

morning,
I am looking to upgrade my rig in the next month or so.
At the moment i have a ivy i5 OCd and running at 4.4 and also a r9 290 OCd .
I want to watercool the lot with a custom loop (will be my first loop) and also add in another 290.
At the moment i have a 850watt PSU.
What do you guys rekon?

850w could be ok. What is the make and model of your PSU?

Yup - Ace Modder's watercooled SLI 780 system pulled around 690w under (very) heavy load: http://forums.overclockers.co.uk/showthread.php?t=18575611

The EVGA Supernova G2 850w is whare i would be putting my money. It's a very high quality Gold rated unit built by Superflower with a awesome 10 year warranty. It's on special at the moment at £109.99. If you wanted extra headroom, the 1000w version is only another £30. Both are fully modular too.

I have the EVGA and it's a fantastic PSU so far I've had no problems at all, and with the 10 year warranty I'll probably upgrade it before I need to use it.

So far I've had 650W and 750W Gold rated EVGA Supernova's and they are great.
I still have my 750W, still works great after 2 years without any problems.
And it is virtually silent.
I switched to EVGA 1000W Supernova platinum rated PSU which was on offer few weeks ago and its even better. G2/P2 is a new edition by the way, so you are buying best tech from best company out there.

The previous EVGA Supernova 650w and 750w units were built by FSP. These units are completely new and from a better OEM, Superflower. That 10 year warranty is unbeatable.
