So I'm going to upgrade my PC by changing graphics card and power supply.
I currently have: Intel Core i7 2600, GT-530 and H-CUPERTINO2-H61-uA TX motherboard. PSU is 200W

What I'm going to upgrade, is get GTX-650 and better power supply, so it will work. Since GTX-650 is with PCI-e 3.0, but my motherboard supports PCI-e 2.0, am I going to have to get new motherboard too? Or are they compatible backwards?

PCI-e 2.0 and PCI-e 3.0 are same, but PCI-e 2.0 is slower.

Yes, PCIe 3.0 cards work in 2.0 slots. And since modern graphics are not yet powerful enough to saturate PCIe 2.0, especially not the 650, you will not experience any performance hits. PCIe 3.0 is twice the speed of PCIe 2.0, so PCIe 2.0 x8 is equivalent to PCIe 3.0 x4, PCIe 2.0 x16 is equivalent to PCIe 3.0 x8, and so on and so forth. But you could put a card as powerful as a gtx 770 in a PCI 2.0 slot, and it would not bottleneck.
