So, I use 2x molex to 6 pin to supply my GPU with power. I plan on buying GTX 650 2gb. How do I know if my 2x molex to 6 pin is properly working? or, how do I know if the GTX 650 2gb will be getting enough power?
My board is H61N .
My CPU is i3-2100.
My OS is Windows 7 ultimate.

Which power supply will you use?

If you get graphics problems, you will know ;)
Usually it will work or it will produce graphics errors or BSODs or freezes or shutdowns or reboots
