White writing is the question, black writing is background, so ignore the wall of text if your mulled wine has hit you hard already!

I am planning to upgrade my PSU for several reasons. Currently i have three PC's which are running 24/7 under load plus my gaming rig. My gaming rig happens to have an OCZ 750w Fatal1ty PSU which has been working wonderfully but is too little to take on my 8350 @ 5.1 and more than one 290x (will be Cross firing later next year when i change my monitor).

Luckily i have received a voucher or two for OCuk today and so was planning to get one of the new superflower ones but i want to avoid spending too much, as it will eat into my project log cash. I want to know just how much abuse these superflower PSUs can take as i over clock quite heavily on my CPU and any GPUs.

Luckily my watercooling keeps power use a fair bit lower than if my rig was on air. Now i know the 1000w EVGA or superflower gold will easily handle two 290xs (at around 1250+/1500) and the CPU but i would like the option to be able to power another in case i end up buying three for benching or to handle the new 21:9 screens coming to us in 2014.

I know i will get a ton of 'BOTTLENECKER!!!!' comments, so lets quench that fire before it derails the thread. Though i have an 8350 in at the moment, i also have a 3770k in one of the mining PCs that i could swap if i feel the need to. Main reason why the fx is still in the gaming PC, is it also doubles as a number cruncher and the program tends to work better on the fx. If mantle turns out half as good as people say, likely i wont even need to change the CPU but i at least have the option.


Is the EVGA 1000w up to the task of powering a heavily overclocked system with:

fx8350 @ 5.1
290x (two in crossfire but possibly three with the nuts clocks off them)

Motherboard, 290x and 8350 runs super cool, so i am sure quite a bit of power is saved through lowered resistances.

Any other suggestions? I would like a fully modular PSU and consistent power delivery would be the main priority with the idea to keep budget as low as possible (150-170?). Bonus points go to the Superflower ones as they have pretty connectors which light up at the PSU :D


Merry Christmas guys!
 
Well the screen is 21:9 3440 by 1440, which essentially would be approaching eyefinity set ups, in terms of pixels (but without micro-stuttering and bezels). I figure that two 290x's would be a good amount of grunt for this with current games but i would like the option of popping another in, in case it isn't enough a year or two down the line.
 
My machine uses around 700w when mining. I do not think a 1000w is enough for three. I reckon you would need a 1200w for 3 X 290x + a power hungry cpu
 
Yeah, especially since 290x's arent clocked up on core when mining and usually are underclocked. Also my 290x when mining uses far less power than when i game, even at the same clocks.

Was trying to avoid spending £200. If only they were at original price lol

Thanks for the replies guys, i appreciate that you took time out on Christmas to do it.
