My computer is a HP pavillon 500-509c. I currently have a Intel Core i5-4590, with 16 go RAM and a GeForce 705M with a 180w power supply. I just buy a GeForce GTX 980 and will obviously need another power supply but I need to find the dimensions of my power supply and find one who will fit and that will be strong enough to support my graphic card.
So I need to know my power supply dimensions and what power supply buy.
 
Solution
You can't upgrade your power source , it uses an adapter for power not a standard ATX power supply.
Total wattage: 180 W external power adapter (100V-240V)

It's a proprietary board and power source , no upgrades.

No upgrade ...Sorry.
