Rule of thumb for psu capacity?

Does these allowances sound reasonable?

cpu 7700k 200w crossfire gpu rx480 400w disk, ram, mb <50w

So 650W should be man enough for most upgrades etc?

Single-GPU systems: 450-650W

SLI/CFX/dual GPU: 650-850W

Keep in mind that wattage is not very important. The quality of it can decide if your PC lives or dies. Always read reviews from trusted sites such as jonnyguru.com or techpowerup.com and dont just blindly follow a brand. Every brand makes good and bad, even EVGA or corsair.

Depends on the system, you can get away with 550w fine depending on the tdp.

I'll be looking to make sure I have plenty of capacity for upgrades and overclocking.

Do any PC PSU's have built in power consumption monitoring?

Yes but they are all expensive

a good one would be the corsair rm650i

That's pretty cool!

In these days of added bling & gizmos, I'm amazed more psu's don't have this.
