Yes ! For sure. GTX650Ti will consume 110W and your whole system will require 450W and if you've CX500 then it is well and good. even if you overclock your CPU then also this powersupply is enough for you.
Sorry re look at my above post and could you recommend a good fan for £23 or cheaper
Cooler Master Hyper 212 EVO is a very good CPU cooler available in your budget.
