5 out of 5 eggsPhew.....

Pros: It works,

Cons: Im afraid to flew the cords to much. shorts I guess but I don't know a thing. what about a single molex cable instead of a 3 headed one. same thing with the sata. These are lessons learned

Other Thoughts: no noises & super quiet. I was so nervous purchasing parts on newegg. I hope this things last. not a heavy load user so I expect it to. The rma nightmares I've read :OOOOOOO

5 out of 5 eggsGreat power suppy, no complaints

Pros: This thing provides plenty of power to my Intel Core i5 3570k CPU/MSI GTX660 OC graphics cards system. My unit has never had any problems whatsoever and has run flawlessly so far. All of the cables have very nice braiding over them and everything being black looks great as well. all plugs attach to everything perfectly.

Cons: Isn't 100% fully modular so you will have to hide away whichever of the cpu power cords that you do not need. But I know this when I bought it (look at the pictures) so no eggs off for that.
Be warned, the cables for the CPU are not overly long, so if you have a case that is bigger than a Coolermaster HAF912, you may have to run the CPU cable across the top of the Motherboard or you may have to get a small extension for that cable. I was just barely able to get my unit's CPU cable to plug in to the CPU plug running the cable behand the motherboard for a clean look.

5 out of 5 eggsOrganized, reliable power supply

Pros: Extremely organized, no tangled cables. I was really surprised that it was so easy to install. Not much to say other than it works fine and doesn't seem to heat up.

Cons: None so far.

Rosewill CHALLENGER Black Gaming ATX Mid Tower
ASUS F2A85-V PRO Mobo

5 out of 5 eggsGreat Power Supply

Pros: -Modular (but not fully modular) helps keep out clutter.

-620W leaves a lot of room for additions to the build.

Cons: -Had a non-detachable cable that I didn't use, kinda defeated the purpose of being modular, but I didn't know at the time that there were separate "modular" and "fully modular" categories.

-The price now. I got it for around $65 with promos, regular price of $85, back in January.

Other Thoughts: -I had heard that SeaSonic was a trusted brand for PSUs, and so far it seems to be true.

-I was torn between this and a Corsair model, I don't think I could have gone wrong with either.

-My Build:
i-5 3570k cpu (at stock settings)
Asus P8Z77-V LK board
Corsair Vengeance LP-1600 16GB
Samsung 840 Pro 128GB SSD
WD Blue 1TB HDD
Seasonic 620W Modular PSU
Lite-On DVD Burner
Corsair 200R case
