I built my first pc and the specs were
Intel core i5 3470
radeon hd 7850 sapphire
CX500 power supply

when i tried to test boot i heard a sizzling noise coming from the heatsink so i unplugged immediately and didn't find any damage other than the thermal paste almost being completely melted

I meant the pre applied one on the stock heatsink. is seemed a little warm but other than that it seems to be fine, no noticeable burns on the motherboard or cpu, and yes i did see smoke

Yikes.

I hope it just fried your MoBo and not your CPU. Chances are you will probably need a new PSU too. If you have another PSU around I would try hooking it up to your MoBo first to see how far you get. Don't use the PCIe power cables. They are the 3+1 connectors. You want to use the 2+2 connector.
