That's what I was thinking. I don't want to go too much higher because the price starts to raise exponentially. Here's a thought though, I've been looking to get into water cooling for a while now and I may be able to soon. Should I take this into consideration power wise since I'm buying a new PSU anyway?
Haha look at the name of the sig rig. Its "Gamer" thumb.gif. I definitely game, but when I'm not home, the PC gets dedicated to folding. Hell, i even fold on it when playing non-system intensive games.
I'd love to see how the 4GB versions perform. Been thinking about NV vision. Later on that though.

I bet you could get away with it however if you plan on folding on two high end video cards and your cpu (all overclcoked) for extended periods of time I would get ether this http://www.newegg.com/Product/Product.aspx?Item=N82E16817151110 or this http://www.newegg.com/Product/Product.aspx?Item=N82E16817151109

Reason being peak efficiency is somewhere around 50-60% load and folding for long periods of time you will notice a change in your power bill. That being said the 1050 will still be going strong years from now.

Check out this review
http://www.tweaktown.com/reviews/4508/seasonic_x_1050_1050w_power_supply_review/index5.html

"Seasonic has once again proven why it is often the choice of enthusiasts. The X-1050 performed nearly flawlessly on our test bench through all of our tests. The voltage regulation is at 1% or less across all three rails which is almost unheard of and rarely seen. DC output quality was almost amazing, staying under 30mV of ripple under full load. Topping it off, the unit excels past the minimum for 80Plus Gold certification.

Performance aside, the Seasonic X-1050 has the rest of the package as well. The full modular design coupled with short and long cables ensure that you only have the cables you need in your system. Seasonic backs the unit with a five year warranty and when you add in the price of the unit, it becomes a no-brainer. The X-1050 gives you a win-win no matter how you look at it."

The point is to run the unit at 50-60 % load since he is a folder, running a power supply at 90% or more load 24/7 for weeks on end is just asking for trouble rolleyes.gif especially since the price difference is like $40-50.

680s are ~200W cards... a solid 650/700W unit would be plenty.

I put it into this calc and with an overclocked cpu at 4.7ghz @1.4v and fans, hard drives and ssd and a decent amount of cap. aging got 837 watts. The price difference is too small to justify stepping down.

I think you are forgetting an additional overclocked 260 core 216. Also as Fatalrip has stated above, I do not want to load the PSU at 90% for the 15+ hrs a day that it is folding. Especially given that I have only seen 80%+ rated PSUs.

That's not what 80+ means. It's a measure of the PSU's efficiency of converting AC power from the wall into DC power for the components, the rest being lost as heat in the conversion. It has nothing to do with how much power the PSU is able to put out.

My feeling with the Molex to PCIe adapter is the Molex rail was designed to power things like fans,pumps,other low amperage devices,not high amperage consuming gpu's. Unless the Molex rail is tied to a high amperage rail internal in the power supply I could see you reaching the limit (in amps )that this rail was designed for.

Doesn't make a difference, the molex cables are tied to the same 12 volt rail(s) and use the same gauge wires as the rest of the cables.
