I'm a little worried on my 750W PSU running crossfire 2x R9 290. I got answered that it will work, but not recommended.
I found gpu use less power while running in low temperature.
I only get worried while the 2 gpu on peak load, other times 750w shall be plenty.
I think each card uses around 250w on peak, and runs over 80-90C hot.
Will I be able to reduce power consumption by water cooling the cards(maybe down to around 60C)? How much power can I save on the GPUs.. and to achive this, how much more power I will use on the water cooling system(pump & fans).. not sure if it reduce or increase my PSU stress.
I guess I'll have to water cool at least 1 card, because the gap between the 2 cards is only about 5mm. The primary card has very limit air intake.
Another question, I think a full water block is really expensive. I'm thinking to build custom loop, cool the cards by using universal single GPU waterblock plus air cool VRM... (like NZXT G10, Corsair HG10, they only works with their own AIO kit...). I know it's not helping on the VRM, but the cost is a lot lower.
Is there such a product can air cool VRM and compatible with custom loop GPU waterblock? (VRM fan bracket can mount on graphics card, or a GPU waterblock can mount a fan)
