I have a PC about 5 years old with a 450W PSU. I've been using the onboard Intel graphics, but concerned that the video socket may be damaged. I have a video card I'd like to try as a backup.
I don't want to overstretch the PSU. If it is drawing too much,, how would that show? Just suddenly dead screen?
What is a good way to estimate power consumption? Tools like HWmonitor show temperatures and voltages, but not power.
