Power Supply Capacity Formula
How can I check if my system needs more PSU power?
I'm not sure if it's OK or not to ask a hardware question here. If not please let me know a good place but I've always got good info here so I thought I'd give it a shot.
I'm custom building a new workstation for coding (Linux/Eclipse). How do I determine how much power the power supply needs? I'm building a mini ITX system on a budget and so I need to get as small as possible that is sufficient.
I'll have a mini itx mobo with on board wifi and bluetooth, 8 GB RAM, an Intel i3 3.1 Ghz processor, 64 GB SSD and a slim optical drive. In the future I might add a descrete GPU, 16 GB RAM, 128 GB SSD. What is the minimum power I need and how do I calculate that?
