PSU Wattage Question

It is possible - but not generally reccomended.
The average power draw of a computer is generally not equal to the sum of the power draw of all components. In order to reach the 371W listed - all components would need to be drawing their maximum wattage - and that is done by doing everything you can at the same time.
This being said it is possible to boot and opperate your PC - but you would be living on the edge of the listed rating of the PSU and the draw of your system. If you step over that line - you might overload your PSU and have an impromptu shutdown.
I generally want some head room in these areas - so a solid brand Tier 2 or Tier 1 PSU (search PSU Tier on Toms) with around 400-450W would be where I would go.
Good luck.
PS - just saw the note about an Old PSU from Dad's computer. First - Dad bought cheep stuff - so the brand is not good. Also Age affects PSUs and it may not be up to the task of it's listed rating.

Once you go above 300 Watts then you probably chose a video card that requires a 6 pin PCI-E connector.
