Lack of juice would be random lock ups, black screen of death when you get to desktop for the first time, random reboots, and other strangeness. I've had it during an upgrade what was a largely undersized PSU when I did my rebuild. I would boot, get up to a desktop and normally within 30 seconds the machine would reboot. As mentioned earlier, PSU's degrade over time, and giving no headroom, you'll hit the ceiling eventually. I've had a 3 year old 550W PSU with the video card recommending I had at minimum 550W PSU, and was having issues in games sometimes, as I recall?
You can get a plug passthrough device to check wattage consumption as well at the wall socket itself. Cheap one's are like $20.
