Great PSU, no problems with it, really easy CPU management thanks to its half modularity. Mine even came with 10 zip-ties :D

Good power supply, haven't had any problems yet. Half-modularity is very nice.

Great PSU. It's quiet, partly modular, and came with the needed wires. What else can I say?

No complaints. I wanted a decent quality power supply, and everyone recommends corsair, so that is what I went with, and I have no regrets. I do recommend modular or at least semi-modular if you'll be building a computer though. Much easier to cable manage.

Stable and well-rounded power supply. Works great for the system. I took a gamble here as the GPU I had recommended a 650w power supply at the least but there don't seem to be any bottlenecks.

Great PSU. The Modular Cables are great for cable management but I wish the 24pin connector had all black Cables.

Should have gone for a fully modular, but this semi modular still works very well. No issues with it, does what it needs to do. Wish I had gone with a larger wattage as well, but that's no fault of the product!

Don't really have any components that will be pushing the PSU. No GPU is present so don't know if it truly performs to the 550 watt rating. Some of the modular cables are hard to insert fully which can be a pain if you think they are seated fully but go to power on the system and some peripherals don't have power

Great power supply, nice and small for ATX, while still being 80+ Gold. Semi-modular design is awesome. Only thing I didn't like was the daisy chain for the PCI power cable, there was a 6+2 and then another 6+2 on the same cable.
