If everything's hooked up normally, it should run just ok. 

 

Techpowerup lists a recommended psu wattage of 450w https://www.techpowerup.com/gpu-specs/radeon-rx-580.c2938 and a Tom's hardware review of the Sapphire OC version showed a power draw of about 220w https://www.tomshardware.com/reviews/amd-radeon-rx-580-review,5020-6.html . AMD seems to have removed the product page but multiple forum posts like this one seem to have the recommended psu wattage at 500w.

 

But anyways, as long as everything's connected as it should (no SATA to PCIe wizardry - there will be system shutdowns if you do it this way) and you don't OC or put it under too heavy a load. It should be perfectly fine. 

 

Just note that a CPU upgrade or a GPU upgrade or even a Motherboard upgrade could significantly increase the total estimated wattage of your PC and with the 400w PSU, there will most probably be some instability.

Decent unit, 12v only. 18A/216w for the GPU. It's on the edge.

I'd say it should be fine. But I wouldn't do another upgrade (unless it's pretty minor) on this psu
