    "so quiet...good psu...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....850w is enough power for anything I am currently using and I like that I can choose what power connections are on it, means less clutter in the case"
