-Completely quiet, no coil whine

-Great cables. Some people don't like them because they say they're too stiff or difficult to maneuver. Ribbon cables are like that. But the advantage is that they can lay flat against each other and stack, overall taking up less space.

Plus, they flex and will keep their shape, so you can mold them as you like.

Only thing I didn't like was the 24 pin main power, as that was divided up into two cables with wires going to different plugs, which is unnecessary and actually makes that cable bulkier. But this is minor.

-Packaged VERY well, unlike the Corsair 750d case I bought


Had a problem with my mobo and I couldn't figure out if this thing was actually on. I used the paperclip test, which is where you connect the green wire to a black ground wire, tested a fan and found out the PSU was ok.

Considering this thing is dead silent whether on or off, a small, subtle indicator light somewhere would be helpful for troubleshooting.

Other Thoughts:

Going to use this to power SLI GTX770s.
