    "Love it...It's ok...I bought this for a friends computer I was building and it was a steal at $52 more than enough power and 80 rated bronze....This power supply is your basic power supply; it gets the job done, plus a toggle power switch--which isn't on every power supply I've ever owned, but now I don't want to not have it."

    "good psu...Works ok...I upgraded from an Nvidia 960 2Gig video card to a 1070 8Gig and when I went to install the card realized I only had a 550 watt power supply with one 8pin connector which was being used by the motherboard (the 960 only needed a six pin connector) I bought this power supply because it is modular and comes with 4 eight pin connectors so it will run my 1070 without issue....This power supply is semi modular which is a lot more awesome than what I had and gave me longer cables to have more options on where I can extend my power to without having to use adapters and extensions."
