    "Good PS...Good PSU...If I didn't have a powerful case fan in between the two components to blow air out, I believe I would be on the market for a totally new machine altogether....When a product says "Modular" on the box, gamers like myself have a image of a certain kind of power supply that allows actually pick the cords coming from the power supply."

    "Works ok...Great PS...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."
