You grab an AX860i for example and thats probably the last PSU in 5 years you need to buy.

It's a common misconception that a system needs more power than it does, and most builds reflect this, partly in an abundance of caution. It's not harmful to over specify the PSU.

It was a great suggestion to ask for power meter readings, because it really is illuminating. And with a power meter reading, you can use it's PSU efficiency graph to see where you are with it, at idle and load.

Corsair has a power supply finder that I think is really useful: Power Supply Finder

I've used it a bit, and now have a simple rule of thumb for sizing a PSU; "250W for each big gaming graphics card, and 250W for the rest of the system - even with overclocking. Newer gear uses even less power, and lowers the operating efficiency on an over-sized PSU.

I use a 650W PSU and run a single graphics card [GTX 560Ti 448 Cores].
