Also how much power will the 650W PC will consume when

There is no way to know. A 650W power supply is the MAXIMUM it can deliver. You need to use one of the power supply estimators and put the config of the hardware you have to get an estimate.

So what capacity UPS should I get? Will a 800VA be enough? or do I need a 1 KVA?

You didn't provide an estimate of what the power usage is so there is no way to answer that. With a UPS, bigger is usually better.

1 Optical Drive
GTX 960/970
A monitor
Keyboard & mouse.

How much power would they use?

Your PC probably peaks at about 300W. An 800VA UPS is rated around 550W. You shouldn't load above 75%. That means an 800VA is good for about 410W. You are probably OK with 800VA. You won't get much time to shutdown. The 1000VA will give you more time to shutdown.
