1200 W Redundant Power Supply
The Supermicro PWS-1K41F-1R is a 1200 W redundant power supply designed for compatible Supermicro servers and chassis. It delivers 12 V DC at 116 A and 5 V DC at 6 A from 110 V AC or 220 V AC input. The unit carries 80 Plus Gold certification for efficient operation.
Rack-Mount Server Deployments
This module suits administrators maintaining the listed Supermicro A+ Server, SuperChassis or SuperServer platforms that require hot-swap redundancy. Sites needing a different form factor, non-redundant power or compatibility with hardware outside the specified compatibility list should look elsewhere.
80 Plus Gold Efficiency Rating
The power supply meets 80 Plus Gold efficiency standards, reducing waste heat and operating cost in supported Supermicro systems. Verify that your chassis model appears in the compatibility list before purchasing.

Questions about this item
How do I install the PWS-1K41F-1R in a SuperChassis 818A-1400B, and what step is often missed?
Slide the unit into the rack-mountable bay until the latch clicks, then secure the retention screw; the step often missed is tightening that screw, which keeps the redundant module firmly seated.
Which component of the PWS-1K41F-1R will need replacement first under continuous 1200 W load?
The internal cooling fan typically wears out before the 80 Plus Gold certified electronics, so plan a fan swap after several years of sustained operation.
What thermal limit appears first when the PWS-1K41F-1R runs at full 1200 W output for extended periods?
The 12 V DC rail at 116 A hits its current ceiling before the 5 V DC rail at 6 A, so the 12 V limit is the first constraint under heavy sustained load.
