Power Supply on the cheap that you can trust 4/28/2020 11:32:26 AM

Pros: 80 Plus certification
Came with black screws
Fan is always on during use but is very quiet
All the cables reach in my Antec Three Hundred case

Cons: Only a one year warranty, expected better with 80 plus certification.
Lack of clip to hold the 20+4 pin together made it a little more difficult to plug in as the 4 pin cable was harder to line up.

Overall Review: Getting this power supply on sale on top of its already low price made it the lowest priced 80 plus certified power supply I’ve ever seen. Granted it’s the minimum certification for 80 plus, but at least it gives some peace of mind knowing it won’t burn up itself or your devices.

Steady reliable power for a good price 4/14/2020 11:28:12 AM

Pros: While you're NOT going to seriously game with this power supply it will do a great job running the AM4 version AMD processors and the Intel i3,i5,i7s with builtin internal video. Those do not take a lot of wattage to run efficiently! Makes this a great value for the money.

Cons: 400watts! Non-modualar.

Overall Review: If you're just wanting a desktop surfer with some reasonable power and speed, this will help accomplish it!
