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

    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!

    Wish the 24 pin power cable was black instead of rainbow, but it's not a huge deal. Good PSU, Corsair is a good, reputable brand and so far it hasn't exploded, so it's a win in my book.

    Got this refurbished for $60 on Newegg. I could have gotten the 650 watt semi-modular power supply for the same price but Im not even using over 400 watts over load so there wouldn't be a point.

    Great power supply. I'm a first time builder so I don't have much experience with PSUs, but the modular cables and non-modular power cable was pretty nice for a first time builder. I don't really like how they daisy-chained the cables, but it works fine and I have had no problems with them. The main 24-pin power cord is sort of large and bulky, but that doesn't matter that much.
