TRIPP LITE SREXTENDER SmartRack Extension Frame for 42U & 48U Enclosures
Quick View

The primary purpose of aĀ server power supplyĀ is converting alternating current (AC) into direct current (DC). The reason is that computers and servers use DC, not AC, which is the type of power that comes from your wall outlet. The power supply is a piece of hardware that powers all the other components of the server with dedicated connectors.

A Redundant Power Supply Prevents Downtime

In aĀ redundant power supplyĀ setting, your server works with two or more power supplies. Every PSU can run the server on its own if the other fails. Under normal conditions, each PSU provides half of the power required to operate the server. MostĀ redundant power suppliesĀ support hot-swapping, i.e., you can replace the PSU without switching the server off. Hot-swapping prevents downtime, which is particularly important in web servers and mission-critical business environments where you need to keep information and work flowing. While you replace one of the power supplies, the other keeps the server running. It is advisable to install each redundant PSU on a different electrical circuit, so the system will keep working even during a circuit trip or maintenance operations.

Linear vs. Switching Server Power Supplies

When consideringĀ power supplies, a linear server and a PC power supplyĀ have a more straightforward construction, and require fewer components to convert AC to DC. They tend to be pretty silent, which is an important factor in some work environments. Like server processors, these power supplies work well in systems with efficient cooling. Switching-style power supplies have an internal switch that controls electricity. This leads to less energy consumption. In comparison with a linear PSU, a switching one tends to have smaller components. However, it also produces more noise.Ā 

Certifications Determine the Energy Efficiency of Your Server Power Supply

80 PLUSĀ® is a voluntary certification program that classifies server andĀ PC power supplies, including power strips, by their energy efficiency. You can obtain the energy efficiency value by dividing the amount of power the PSU provides by the amount of energy it draws from the power outlet. 80 PLUS Titanium PSUs are the most efficient, as they offer 92% energy efficiency at 20% load, 94% efficiency at 50% load and 90% efficiency at 100% load. 80 PLUS Platinum power supplies offer 90% efficiency at 20% load, 92% efficiency at 50% load and 89% efficiency at 100% load. 80 PLUS GoldĀ PC power suppliesĀ provide 87% efficiency at 20% load, 90% efficiency at 50% load and 87% efficiency at 100% load. There are other 80 PLUS certifications with inferior efficiency requirements, but they are less common in server PSUs.Ā 

Server PSUs Come With Different Connector Types

Server power suppliesĀ come with different types of main ATX connectors. The most common connector in older motherboards is the 20-pin one. Most modern motherboards, instead, feature the 24-pin connector. You can also find PSUs with a 20+4 connector, which works with any motherboard, whether it has the 20-pin or 24-pin connector.

Works, could be better setup, especially given the form factor it is expected to be used in

ā€œ Despite the shortcomings, the price makes this power supply a good deal and I would happily buy it again if it was still available. ā€

Only suitable for professional use, not a personal desktop

ā€œ I'm sure this wouldn't be an issue in an isolated server room, as this is a server PSU. ā€
