I'm thinking about getting the Radeon 295x2 for my first PC build but I'm not sure how I would connect it to a power supply correctly. From what I've read it's a pretty toasty card and without the right power hook up it can catch fire or melt. I was wondering which PSU would be compatible with this card and how I would go about hooking it up? Thanks!

Found this on a review: "As you'd expect, the R9 295X2's power requirements are rather high – it has a whopping 500W TDP. Power will need to be supplied through the dual 8-pin power connections mounted along the top, but you'll need to make sure your PSU is up to the task; the two connectors must be powered by separate +12V rails, and each of these rails must be able to supply at least 28A. Your PSU also needs to be able to supply at least 50A across all of its +12V rails, so you'll need to check your documentation to confirm the requirements are met."

It depends on what CPU you are using. An i5 is very different from an FX 9590. Also, 8 HDDs is different than 2 SSDs.

As far as the rails go, you don't necessarily have to have multiple 12v rails as long as you select as PSU with the proper output. A single 12v rail on a capable PSU will work the same.

Assuming you have something around the i5 or i7 level I would go with the 850w EVGA Supernova G2: http://pcpartpicker.com/part/evga-power-supply-220g20850xr but if you want to overclock heavily or have a higher TDP CPU then 1000w may not be a bad idea.

In PC months that's like 5 years,

Pretty exciting stuff though,
