Asus GTX 1080 ti Power requirements

[breaknight]

I'm Going to buy a asus gtx 1080 ti stix gaming.
I was wondering if my power supply would handle it?

My pc specs are...
Ryzen 5 1600(stock)
gigabyte ax370 gaming 5
16 gigs of corsair ram
corsair h100 v2
samsung 850 evo 250
Corsair cx550m?
9 case fans
(old Gpu)Asus duel gtx 1060 3gb

Would i have to upgrade the power supply?

The CX550M can handle your specs with the 1080ti.

No need to upgrade.
