AMD 3700X & RX 5700 XT on a 450W PSU

TL;DR - A 450W PSU is plenty for a 3700X & RX 5700 XT.

My desktop has a 3700X & a Sapphire 5700 XT Pulse which I'm running off a 450W SFX Corsair PSU. Sapphire actually has a 600W PSU requirement up on their website.

I did some tests on the power draw from the wall just to see where I'm sitting.

The power measurement shown is from the wall, so you would have to factor in the efficiency aswell. Despite being way under the 600W requirement on Sapphire's website. I'm still nowhere near the limit of what the PSU is rated to supply.

Actually given my numbers a good quality 350W PSU might actually work too.

Here are the numbers, might be of interest to some - see below:
