4 x 290 Watercooled?

I know Kaap and a couple of others have run something similar, im tempted to put another 3 x 290 into my PC and watercool the whole lot.

Interested to hear thoughts / experiences of anyone who has done similar.

Im thinking a 1200w SF Plat Rated would power the lot too
 
I'm guessing, but I'd say you'll need a lot more power than that, especially if overclocking the GPUs and CPU.

Kaap's 4 290Xs used near enough 1800W at the wall if I remember correctly (albeit slightly overclocked as was the 4930k).
 
haha ok, i know 8pack run 4 x 290 on a single 1200w Plat, the cpu wont be overclocked, the gpus might end up undervolted too, this builds for a mining rig :)
 
AMD must be laughing all the way to the bank with people buying ridiculous amounts of their gpu's for mining.

I'd go for a 1500W PSU minimum personally.

Yes true Matt, although I have to say of all the 7990s I know of (including mine) the vast majority have been RMAed due to issues following constant mining use. Mine was heavily undervolted and underclocked on both cores and I've just had to help out the fella I sold it to with an RMA. If you see a well known competitor's customer support forum, every second thread is about failed 7990s. This is all slightly off topic but just mentioning it in the context of mining.
 
I reckon if i scaled it back to 3 x 290 it would be more than fine on the 1200w SF Plat PSU, just need to figure out what watercooling bits i need to make this come to fruition, i already have a Phantek case so i know i have plenty of room to maneuver.

Time to get googling :)

Don't know how familiar you are with watercolling but I'd go for 3 reference 290s and then you need to buy the blocks (+/- backplates), pump/res (a D5 + res of your choice or go for a combo), tubing, connectors (compression or barb), fluid. I normally buy some sort of stop/drain valve or similar to make emptying the loop easier. All this will cost a bit but if you're set on it, it makes a nice little project.

Rad-wise I'd go for a 480 or 360 and 240 but if you're not overclocking you won't need too much.

Not surprising. I doubt most of them even bother to monitor temps, or even increase the fan profile. Let alone under volt or lower clocks. During games i noted 7990 VRM temps are around 10C lower than core temps. When mining that trend is reversed and VRM temps are 10c+ higher. Needs a more aggressive fan profile to keep things in check. Noticed that myself during my first two nights of my brief mining experiment.

Keeping my 290's for gaming only. :cool:

Yeah 3x290 Pro's on a 1200W PSU sounds good.
 
If the superflower 1200 plat is good enough for 8pack to say it's all good for 4 290's, then what better recommendation do you need? If you're undervolting, then why not?
According to him, it may as well be a 1500-1600 watter iirc.

I have one waiting (for waterblocks) to power three 290's fwiw.
 
Yeah Alex, i was thinking a 480 and a 360 would suffice, can drop in a bay or tube res into the case with a decent laing pump or something, also a couple of temp led's and a drainage point.

In that case, furry muff. Didn't see the mention of that. Using a superflower 1000W Bronze PSU myself and seeing how this performs its understandable to think a 1200W platinum version would be superb and could support 4x290's.
 
Me? Only AIO's tbh, not a proper full custom loop, but im convinced its that hard if you take your time and thoroughly test everything, make sure theres no leaks etc and dont skimp on components. I'd be using hose clips etc and run the thing outside of the case for a few hours to leak test and whatnot.
 
Compression fittings are good, so no need for hose clips. The trouble with water cooling is the price. You would need to spend 3-4 hundred on rads/pumps/fittings and then add on the price of waterblocks, which at a guess are ~£80 each. Basically, it all starts to mount up and would take a long while to get back what you paid.

£300 each GPU = £900
Waterblocks = £240
rads/fittings = £350
Case to fit it all = £150

That is £1640 total roughly and that is not including CPU/memory/PSU/Mobo/HDD, so you can see roughly the cost. I just wanted to give you a heads up before you jump in. I would justify it though :p

Radeon shortage in the US. Ouch at those prices. :eek:

Just shows how popular the AMD's cards are. Tbh im very very happy about the current price.

if i decided to sell my two 290x I would most likely make a profit selling with the blocks :O
