720478-B21 HPE 500W Flex Slot Platinum Power Supply Kit

720478-B21 is the HPE 500W Flex Slot Platinum Hot Plug Power Supply Kit. Flex Slot power supplies share one electrical and physical design with hot-plug, tool-less installation, so a power supply can be right-sized to the server configuration. This Platinum unit supports power efficiency of up to 94%.

It is a core option for the ProLiant DL380 Gen9, whose 8SFF base model with one processor ships with one of these 500W units, and for the ProLiant ML350 Gen9. A DL380 Gen9 takes a maximum of two Flex Slot power supplies, and every supply in a server must have the same input voltage, output rating and efficiency rating. Mixing different supplies can limit or disable features such as power redundancy.

On the ML350 Gen9, the X4 RPS Enablement Kit 802988-B21 is not supported with the 500W unit. The other Flex Slot kits are the 800W Platinum 720479-B21, the 800W -48VDC 720480-B21, the 1400W Platinum Plus 720620-B21, the 800W Titanium 720482-B21 and the 800W Universal 720484-B21.

The spare number is 754377-001, a 500W Flex Slot Platinum hot-plug supply for use as primary or redundant supply, 94% efficiency, requiring 100-240VAC at 50/60Hz. A 6-foot IEC C13/C14 jumper cord, A0K02A, comes with each standard AC power supply option kit.
