How much power is really needed from a PSU?

I bought one of those power meters that plugs in between the wall socket and the computer to measure the current draw etc.

I tested it on an I5 4670K system with a GTX970 gfx card and 16gb RAM with a 1TB Seagate HDD

At idle , it pulls only about 50W and when used during benchmarking, it rises to about 150W - I remember a 500W PSU being regarded as the minimum for this combination - can that be right or is my meter not working correctly?

I will do a proper stress test tomorrow - it was just a userbench run so rather quick and easy

Co-incidentally, just tried it on another system - Ryzen 3900, 16GB RAM, RTX 2060, X470 Mobo - 288W
