Power supply for compact servers

The Silverstone Strider Plus ST85F-P delivers 850W of 80 Plus Silver certified power in a 160mm deep chassis. Fully modular cables keep routing clean and support dual EPS 8pin connectors for multi-socket boards. A 135mm fan runs as low as 19dBA for quiet operation in dense racks.

Practical limits of the ATX12V/EPS12V standard

The single +12V rail is regulated to ±3% across the 850W range, which covers most dual-socket server builds. Depth of 160mm fits standard rackmount cases, but larger redundant units will not share the same bay. Cable lengths suit typical server layouts; very deep enclosures may need extensions.

Installation notes and common issues

Modular design lets you connect only the cables required, reducing clutter in tight chassis. The 135mm fan orientation must match case airflow direction to avoid recirculation. Ensure both EPS 8pin connectors are seated firmly; loose pins are the most frequent cause of no-post on dual-CPU boards.
