I have a 450w PSU rated 132W at 12v rail and 40w at 5v rail.
my cpu TDP is 54W and Gpu TDP is 100W
my system is runiing perfectly but according to the fact that cpu,gpu uses 12v rail only my 12v rail is insufficient to provide 154w combined.So how how is my system up and running?

does my cpu,gpu use the extra 22 W FROM THE 5w RAIL.?
