Died after 2 years 4/8/2018 11:48:07 PM

Pros: Worked fine until I upgraded from a 680ti to a 1060

Cons: After I upgraded to 1060 my computer would regularly crash under load.

Overall Review: I did the online calculator for my PC under load and it said 550W, so I thought this would be fine, but it has failed.

Great cheap modular PSU 11/2/2017 6:09:26 PM

Pros: Very low price for 80 Plus Gold PSU that's semi-modular. Provides all of the cables needed for a basic build. PSU fan is very quiet also.

Cons: None

Great Price, Great Performance 8/5/2017 6:18:50 PM

Pros: -Bought this PSU about a month ago when it was on sale for about $60
-More than enough even with a new Ryzen system and 6 fans
-Semi-modular, but still great because you need the non-modular cables regardless
-Sleeved cables except for 24pin
-80 PLUS Gold rating, a blessing for the price i got it for

Cons: -Ketchup and Mustard colored 24pin, but easily dealt with using electrical tape

Overall Review: Incredible power supply, the 80 PLUS Gold rating is needed for a Mid/High end system
100% buy this power supply if it drops below $70

Awesome fully modular PSU 6/4/2017 7:27:00 AM

Pros: So far so good after about month and a half barely notice it when it is on

Cons: There is a fan noise that comes from the pc when it is placed vertical, however that might be another separate problem as parts were all placed at same time

Overall Review: Came with all parts and components. Zip ties, cables that were all easy to install. It was a breeze to setup that I barely even remember doing it. I am told not to skimp on power supply so I tried to go on the higher end of price range. Still reasonably priced

Decent, random Volt spikes for GPU 12/25/2016 4:55:02 AM

Pros: - It's a decent PSU and semi-modular

Cons: - Inside looks like someone dropped pudding everywhere
- 8Pin to 6+2Pin cable produces voltages in excess of 1 million volts on 2 different GPU cards I tried and 2 different monitor programs
- Not a good choice for a Mini-ITX build, mobo cable is way too long for my build space

Overall Review: I will probably upgrade to a fully modular PSU in the future. I am not sure if the 8Pin cable for the GPU is broken or the PSU itself is not giving out the right voltages. I tried two different GPUs, MSI RX 480 Gaming X (6+2Pin) and VisionTek RX 470 Reference (6Pin) and both record 1-2 million volt spikes randomly in two different hardware monitor programs.

Easy Install & Works great 12/18/2016 9:59:42 AM

Pros: Installation was easy, didn't take longer than 10 minutes to install the unit and attach all of the correct cables.

Cons: So far, nothing is apparently wrong with the unit.

Overall Review: I've only had the unit for a few days so we'll see how it holds up under heavy extended use.
