Overall this product is good because of its modularity. The wattage is good for my needs and because its modular its easy to keep cables tidy and organized. One thing I am not a fan of is the power port orientation. I wished it was different because I struggled to use ishift on my case. I was able to figure it out but I'm just afraid of the tension on the cable.

Picked this up for a new PC build and it's been running great. The installation was straightforward, and the fully modular cables definitely made things a lot cleaner inside the case. Everything powered on the first try, and it's been stable without any issue. Running a Core i7 & PNY 5060 without breaking a sweat. Also really quiet – honestly can’t hear it at all most of the time. It seems well-built and came nicely packaged too. No complaints so far. Hopefully it holds up long-term, but first impressions are all positive. Would buy again.

Going from an old non-modular to this unit significantly increased my efficiency and it cut noise way down too. The new cables are pretty and tidy, the fan is quiet when it does run, and coil whine is practically zero.
