SilverStone Adds 450W Power Supply to Essential Series Line

SilverStone technology is expanding their essential series power supplies with the introduction of a new 450W model. As the name suggests, these are basic power supply units lacking extras such as modular cabling. The intention is to provide a good performance-per-watt over other PSUs. Like the rest of SilverStone’s power supply line however, the Essential series features compact units, with high power densities. This model in particular has a 249W per liter and is only 140mm long.

80 Plus Bronze Essential Series

This unit comes with an 80 Plus Bronze rating. Which means by 230V EU standards, it is 88% efficient at 50% load and at least 85% efficient under 100% load. It has Active Power Factor correction as well as a host of protection features. This includes over power, over voltage and short circuit protection built-in. A single 120mm fan handles the active cooling duties and it has a minimum noise level of only 18dBA. This fan remains quiet most of the time, only ramping up beyond 500 RPM after 55% load, and is still under 1000 RPM at 75% load.

It is non-modular, so all the cables are attached on the same starting point as the rest. Other than the essential 24-pin, and 8-pin ATX 12V connectors, it provides two 6+2-pin PCIe connector cables. These are 500mm long each, similar to the 24-pin connector cable, while the 8-pin CPU power connector is longer at 750mm. This makes cable routing much easier since it can take the long-way at the back when managing. As for drive connectors, it has four SATA connectors across two 500mm long cables and three 4-pin peripheral connectors across two cables.
