Is my psu enough for asus gtx 1080 strix

[joe530]

i have a corsair rm550 will it support a Gtx 1080 strix a8g

Yes, more than enough, 550RMX can even handle 1080ti
1080 tdp is 180W, CPU < 100 W, others 50W, max draw should be less than 350.

Should I get a 880w psu to overclock or 550w psu is good?

If you are going to overclock both CPU and gpu, get Rmx650/Seasonic focus point 650/evga supernova g2/g3 650
