I recently obtained some old computers from a charity shop.. I want the PSU from one, and the graphics card from the other. They were left outside overnight as the shop had considered them scrap (simply for having no cables), there was no rain that night, but it was cold..
I have left the computers to dry for over a week next to a radiator.
How safe will it be to use the parts in my gaming pc?
Also, how do i work out Wattage needed? Is it just better than the most demanding component (the G card most likely) or is it cumulative of all parts in the machine?
Sorry for my ignorance, I'm new to this side of computers.. Any help is much appreciated.
