I have a Dell Inspiron 3671 desktop that has 12GB of ram (8GB & 4GB sticks) that I would like to upgrade to 2 8GB sticks for a total of 16GB. The current power supply is a 260w Bronze. Will that be enough power for the ram upgrade? I also would like to replace the current 1TB hard drive with a 1TB ssd or perhaps keep the hard drive and add a 500GB SSD. Would I still be OK with the current power supply? The computer processor has onboard graphics and I do not plan on adding a dedicated graphics card.
