An 80+ Gold Unit, that is modular, that is over 550w, and it is under $100?! Wow. This power supply is a winner for sure.

The modular cables are the same cables and connectors Corsair has been using for years, and they work.

This unit is very quiet. The fan never really got loud in my system with Dual-GTX670 graphics cards. There was also no noticeable coil whine.

The 4 6+2 Pin PCI-E power connectors was welcomed. It allowed me to run my Dual-GTX670 video cards without any need for extra adapters. I also like the way Corsair handles their PCI-E power connectors, with one cable with two ends on it. So I only have to run one cable from the PSU to the graphics cards. This makes for a cleaner looking case with less cable clutter.

The flat black stealth cables are very nice. Again, this leads to a nice looking cable clutter free case.

The single 12v rail is good as well. I don't like single rails on power supplies larger than 850w, but on a 650w unit like this I like to see a single rail. I've had power supplies shut down on me because of an overloaded 12v rail.

This power supply looks very good. The matte black paint is looks classy, and doesn't pick up fingerprints. The flat black cables look good, and the sleeved 24-pin connector looks nice as well.

Corsair has put the labels on the sides of this unit on so that no matter how the unit is mounted in your case the label will be the right way up. It is little details like this that Corsair always seems to pay attention to, and it is why Corsair power supplies are so great.


The biggest con I have with this unit is the 24-pin connector. It is nice that it is sleeved, however I would prefer that it used the same flat black cables as the rest of the cables on this unit. Also, the sleeving used was kind of thin, allowing the colored wires under the sleeving to be seen through the sleeving. The sleeving doesn't go all the way to the 24-pin connector either, which is common for this type of sleeving. So bare colored wires are clearly visible sticking out of the motherboard.

This is really the only con I have with this unit.

Other Thoughts:

This unit powered the following system without any problems:

Intel Core i7-875K Overclocked to 4.2GHz
16GB DDR3-1600 RAM
eVGA P55 FTW 200 Motherboard
Dual ASUS GTX670 4GB DirectCUII Graphics Cards in SLI
2TB Seagate SSHD
Corsair H100i CPU Cooler
