Re: need advice for a upgraded PSU
The fan either connects to the motherboard or a 4 pin plug on the PSU.
The wireless mouse and keyboard will draw no power as they are powered by batteries. The only thing that would draw power is the receiver, which is very little.
A wireless adapter would also draw very little power.
The external hard drive relies on its own power source so it would draw no power.
Things that you should be concerned with in terms of drawing a lot of power and choosing the right PSU are:
- The CPU
- If it's overclocked
- Graphics card
- Internal mechanical hard drives
