650w psu for gtx760 sli

[akalurken]

Acually i have:
corsair tx650v2 psu
asus z87-a motherboard
i7 4770k@4.3ghz (hyper 212 evo air cooling)
a case with 4 fans
1 hdd 7200rpm
1 sdd
1 pci sound card
gtx650 (will be replaced)

My question is if i can do a gtx760 non-ti sli or i have to go for a 660ti sli?

The 760's are 170w cards and I've run SLi'd 170w cards on a Corsair 620w PSU.
