500 Watt... for the GPU alone.

Another brief story

I wonder how much it can produce.

mersenne.ca says it'll rate around 1229.4 GHz-days/day. I'm planning on picking one up, but I need to upgrade my 700W PSU to a 1500W PSU. ~$1900 for both. A whole paycheck man.

hmm... what do you have in your system?

A decent AMD motherboard with AM3 socket holding a Phenom X4 965 3.4GHz, a SATA 6 Gb/s 1 TB hard drive, 12 GB (4 GB x 2 + 2GB x 2) 1600 MHz DDR3 RAM, a GTX 560 Ti, and the aforementioned 700W PSU. All pretty state of the art when I built it in 2011, aside from the PSU, but it was cheap. $800 or so for the lot with awesome mid size case. I knew the first thing I was going to do when I got around to upgrading was buy a better PSU. Still debating if I should keep the 560 in the machine with the 295x2... I have lots of fans in it and the card has two fans on its own, but I fear 500W 295x2 + 300W (I think?) from the 560 will be too much without additional fans/cooling solution.

I would say replace the 560 with the 295x... a 1000W PSU should be fine, I think.

Some of the reviews I read recommended atleast 1200W, and by then the price difference between 1200W and 1500-1600W isn't even that big. Might as well future proof if I end up wanting to crossfire this beast of a dual card.

I don't think a 560 is anywhere near 300 W.

What effect would the liquid cooling on the AMD card have on case temps? That should keep a good bit of heat out of general circulation. What kind of ventilation does the 560 have?

No idea really, never used isolated liquid cooling (or liquid cooling at all, always been a fan guy). My source said peak 300W for the 560 Ti when doing high intensity stuff, weird. The GTX has two fans on the card itself, and there's a lot of space inside the case right now since it's mid-size. One side of the case is grated so there's some airflow, and there's one 120 mm fan and two 200 mm fans inside the case. I suppose the best thing to do is try it without the 560 inside and check temps, compare and see if it's already too hot.

Bad one effect, maybe? You may (or may not) need an additional fan to cool down some parts of the mobo. For example, since I switched to water for the CPU and 2x580s on one of my rigs, I start getting problems with the memories and one of the chipsets. The problem was that the air circulation in the case was bad, due to [U]removing the big fans of the cpu cooler[/U]. Before, these fans were blowing a lot of (warm) air around, cooling the memories and the mobo too. After installing the water cooling, the memories especially started getting very hot. The problem escaped for a while, as there is no thermal detection for "memories temperature". Until my second neuron in my head started to function, and I moved one thermocouple (the mobo has 3 thermocouples, each with about 40 cm of wire) close to the memory slots. Then I understood the problem and I mounted a small 5 cm fan to blow there. Everything was fine again.
