Know before you buy
This unit is designed specifically for 1U Supermicro server chassis that support redundant power modules. Please verify your server's specific power supply slot compatibility and the gold finger connector configuration before purchasing.
Seller-refurbished means the unit has been inspected, tested, and restored to full working condition to meet original performance standards. It includes a 365-day warranty to ensure reliability for your critical infrastructure.
Yes, this power supply supports global voltage selection, including 120V and 230V AC inputs. However, it is designed for server-grade power distribution units (PDUs) rather than standard household wall sockets.
In a redundant configuration, two or more of these modules work together to power the server. If one module fails, the other takes over the load instantly, preventing system downtime.
This model is engineered with optimized thermal management and specifically designed to maintain reduced fan noise levels compared to standard server power supplies. While it is quieter than many industrial units, it is still intended for data center or server room environments.
