A:Answer The GTX 1080 can hit 250w at max load, it would be very dependent on what else is in your build. What CPU/Motherboard do you have? what other additions that draw power directly from the system (Sata Drives, pci cards etc). This particular power supply ended up powering an old-school X6 Phenom (125w), two internal Sata SSD's, two external mechanical drives and a GTX 480 (250w).
Will it run the gtx 1080? yes, sure... just be sure not to push it too hard..
