Silverstone DA550 Gold ATX Power Supply

The Silverstone DA550 Gold is a fully modular ATX power supply rated at 550W with 80 PLUS Gold certification. It uses a single +12V rail design and Japanese electrolytic capacitors. A 120mm FDB fan operates at a minimum of 18 dBA. The unit measures 140mm in depth for compact integration.

Suited for quiet home

Builders who require higher wattage for multi-GPU configurations or extreme overclocking should look at something else. Systems needing a different form factor such as SFX or TFX will not be compatible. Users who prefer non-modular cabling for cost reasons may prefer alternative units.

Straightforward ATX installation

The flat cables allow tighter folding and easier routing inside the case. The specially designed cover helps dissipate residual heat effectively. Ensure the case accommodates a 140mm deep unit and that the 120mm fan orientation matches your airflow plan.

Questions about this item

What ATX motherboard and components do I need to connect to the 550W fully modular power supply?

You need an ATX motherboard with a 24-pin connector, a CPU power connector, and any GPU or drive cables you choose to plug into the modular sockets.

Will the 120mm FDB fan running at 18 dBA minimum stay quiet next to older case fans I keep?

Yes, the fan operates at a minimum of 18 dBA, so it adds very little noise alongside existing fans in your system.

How can I confirm the 80 PLUS Gold efficiency is working after installation?

Monitor your wall power draw under load; the unit meets 80 PLUS Gold targets, so AC input should be close to the rated efficiency curves.
