650 Watts PSU run 1080

[SkyeClaw]

Hi, was just wondering whether my 650 watts PSU can run a GTX 1080.

Depends on what other components are used in the system, and the brand and model of PSU.

PSU?
CPU?
Present video card?
Memory?
HDDs?
SSDs?
Fans?
Extra Cards?
Water CPU cooling?
Extra components?

I have a a I5-4690 @3.50 GHz
XMS 8GB ddr3 RAM
My current GPU is the GTX 650
3 fans in the computer
No ssd or extra components

OK. Assuming 1 HDD, and 2 x 4 GB memory(?)

The system power draw with the GTX 1080 installed should be around 350 W. So the 650 W PSU should be OK to handle this load, UNLESS, the PSU is a low grade unit, and/or it has been subjected to heavy loads at some stage, and/or the PSU is an old unit.

What is the make and model of the PSU? And how old is it?
