The SKU:PWS-1K03A-1R is a Supermicro high-efficiency, redundant power supply unit (PSU) commonly found in enterprise-grade 1U/2U servers and storage arrays. It is well-regarded for its reliability and its "80 Plus Titanium" level efficiency.

It is a standard component for many Supermicro SuperServers and SuperChassis models. Because it uses a proprietary "Gold Finger" connection, it must be plugged into a compatible Power Distribution Board (PDB) rather than standard ATX cables.

Some of theri key features:-

• ::80 Plus Titanium Efficiency: This is the highest efficiency tier available, meaning the unit generates very little waste heat, which reduces cooling costs in data centers.
• ::Hot-Swappable: Designed to be replaced while the server is running (provided you have a secondary PSU installed for redundancy).
• ::PMBus 1.2 Support: It features digital management capabilities, allowing your server's BMC/IPMI to monitor real-time power consumption, temperature, and fan speed.
• ::PFC (Power Factor Correction): Includes active PFC to ensure power is used as efficiently as possible from the AC source.
•  

Caveat:-

When replacing this unit, ensure the firmware revision matches your existing PSU if you are running a redundant pair, as some older PDBs can be picky about mismatched revisions. 

For you to add this as a second PSU for redundancy, it is highly recommended (though not always strictly required) that the Firmware Revision and Revision Number (e.g., Rev 1.0 vs 1.1) match your existing unit to avoid PMBus communication errors or "Amber" status lights in the IPMI.

• ::To get the full 1000W output, you must provide 200-240Vac input.
• ::If plugged into a standard North American 110-127V wall outlet, the output is de-rated to 800W.
