Silverstone Strider Platinum 550W ATX PSU

This compact ATX power supply delivers 550W of continuous DC power from a fully modular design. Its 140mm depth helps it fit into small chassis while maintaining 80 PLUS Platinum efficiency. A 120mm fan stays off below 20% load for silent operation at idle.

Suits builders of small high-efficiency systems

The Platinum rating and semi-fanless mode benefit quiet, space-constrained PCs that run at low loads. Builds needing more than 550W or a longer cable reach for full-size towers should consider higher-wattage or longer-depth units instead.

Single +12V rail with 3% regulation

A class-leading single +12V rail provides tight 3% voltage regulation and low ripple under continuous 24/7 operation at up to 40°C. This rail design is the key spec that determines whether the unit can cleanly power demanding components.

商品問答

What cables might need replacing after long-term use?

All cables are fully modular so only the specific cable showing wear needs replacement.

Which protection triggers first during sustained heavy loads?

The unit is rated for 24/7 continuous output at up to 40 operating temperature before thermal limits engage.

How loud and hot does it get when running all day?

The 120mm fan stays off below 20 percent load for silent idle operation and spins up only when needed.
