HP-BL20P-Enclosure-Hot-Plug-Power-Supply-3000W-253232-001-226519-001 Recently I picked up this 48v HP hot plug server power supply. There was no good documentation from HPE so here are my findings. HP Part # 2226519-001 Spare Part # 253232-001 Input 200-240V single phase AC 20 amp 50/60 hz Output 2950W max 51.4VDC 57A max with 25w 5v output Double pole/neutral fusing AIMS Power  The end goal is the use this for a grid-tied smart solar charger.

Good news, installing a RX-470 8gb MSI gpu was a success. After some BIOS tweaking and power settings it works with multiple monitors. System still thinks it is using the AMD ES1000 8GB which is the HP stock driver for the 64mb VGA driver. Currently have Ubuntu server 19.04 installed with SLiM & Ubuntu Minimal desktop. Got phoronix-test-suite running. A lot of failed tests . The system is not optimal for a lot of these tests. Next step is adding USB 3.0 to PCI 2.0  cards for I/O. 10 pin to 8 pin PCI-E power cable HP G7 PCI-E expansion board
