5 out of 5 eggs

Pros: Nice looking PS.
Braided sheathing over all the cables.
Even comes with black screws, how thoughtful.
SUPER long cables, you could run these things around the outside of the case and still have room.
Quiet.

Cons: I wish there was a way to simply unplug the 8 pin connectors since I won't be using them. So I will have extra cables to put somewhere. Little thing but I thought I would mention it.

Other Thoughts: I bought this to use 2 GTX 470 sc cards in SLI. So having the extra wires for for 8 pin PCI-e will make it hard to hide the extra wires that I won't need. It would be nice if they had a second connector near the Power supply to unhook them if needed, sort of like an extension. It's nice that they have them if you were using a set of cards that reuired them, but then you wouldn't need the 6 pin connectors. So making them removable would be a slight bonus.

Cons: dead on arrival and did not come with the two 8-pcie connector to 6-pcie adapter

5 out of 5 eggs

Pros: Quiet, heavy duty power supply. Large diameter cooling fan is quieter than smaller diameter models.

Cons: Could have used a few more of the 4 pin drive connectors.
The first unit had to be rma'd because it looked tampered with. Newegg probably repacked it after a return. Sorry, I can't risk a $3000 system. If it's an open box item, say so.

5 out of 5 eggs

Pros: lots o power, easy to install and set up.

Cons: wish it was modular, as I have a lot of extra cables stuffed down in the bottom of the tower. Wish I could just plug in what cables I need into PSU.

5 out of 5 eggsWow

Pros: You simply can not beat this thing. I am told part of the reason my components are operating so well is that they are recieving clean power. This thing is great. Nice long cables and has every cable youll need to run even the lastest cards.

Cons: None so far.

1 out of 5 eggsFailed

Pros: Lots of power, lots of long PCI-E 6-pin and 8-pin cables

Cons: Died after 1 day

Other Thoughts: PC turned by itself. I pushed the power button, and heard a very loud POP!!! No burn, no smoke. Just a pop. I swapped it for another power supply (with everything but motherboard connected), and it powered up. I put the 850W back again, pushed the power button, no response. RMA'ing now. I hope it's just the power supply failure, and I hope it's I won't get another bad product.

I'm getting another PSU just in case.
