Ample power for my build, feels solid, and is incredibly quiet. It isn't modular, but to be honest that didn't really matter with the S340's HDD/PSU bay. Everything is tucked away nice and neat. At the price paid it was a no-brainer.

Got it for around $30 after the mail-in rebate, definitely worth it. The cables look good too, all black.

Enough power for my system, reputable brand, it just works.... and my case has a PSU shroud to hide the mess of unused cables.

Get a modular PSU is what I have learned. Dealing with these power cables which you can't remove is the worst.

Otherwise good PSU.

Plenty of wattage for this build. I found that you want your wattage ceiling to be about 200 watts above the max estimated wattage for your components.

The GPU is between 30W - 120W.

The CPU is between 8W-65W.

The MB is between 15W-60W.

I read so many contradicitons about PSU's what's good, bad, great, better value or more efficient, I decided to go with the CX550 and due to the case affording plenty of space for storage I didn't feel the need to go modular.

People talk bad about the Corsair CX series, but the 2017 version has long black sleeved cables, solid efficiency, and a five year warranty. Very happy with mine.

Why the hell did I not buy a fully modular PSU..? Other than that it works flawlessly.
