You need to look at the spec of the power supply.

Even though it says "400W", it might not necessarily BE a true 400W.

The "400W" rating, depend on the quality of the units, is the OVERALL rating.

That includes the +12v rails, the +5v, and +3.3v, etc.

 

Where are you calculating 385W?

What are the parts you are trying to run?

 

Because, if you are using a online calculator, it might not take into account the EXTRA power spikes, and extra power used during 'Boost' states.

Example, the Intel i9-9900K is rated as "95W".

When that damn chip is under 'Turbo Boost', or when Multi-Core Enhancement (MCE) is enabled in the BIOS settings, it can exceed that "95W" rating.

It can jump all the way up to 150W+.

15W headroom is NOT going to be enough.
