Compact SFX 850 W unit for small-form-factor builds

This FSP Dagger Pro SFX 850W power supply fits Mini-ITX and Micro ATX chassis with its 125 mm length. It delivers 850 W through a single +12V rail and meets ATX 3.1 and PCIe 5.1 requirements. The fully modular design uses flat ribbon cables to keep airflow clear in tight spaces. 80 PLUS Gold certification means efficiency above 90 % at typical load.

Suits builders who need high wattage in an SFX

Buyers who want more storage connectors than five SATA ports should look elsewhere. Systems that require multiple PCIe 6+2-pin plugs for several graphics cards cannot be supported. The 110-120 V and 220-240 V input range covers standard mains worldwide. Cybenetics Standard+ noise rating indicates quiet operation.

Native 12VHPWR connector for ATX 3.1

The included 12VHPWR cable powers next-generation GPUs without an adapter. Two 24-pin ATX connectors and a single 6+2-pin PCIe plug complete the modular set. Active PFC and >79 % efficiency at low load round out the electrical specification. Made in Taiwan.

Perguntas sobre este artigo

Will the 12VHPWR connector or cable need replacement down the line?

The native 12VHPWR connector is built to the ATX 3.1 and PCIe 5.1 specifications, so it is designed for the full product life without a scheduled swap.

What limit appears first when the 850 W unit runs at full load for hours?

The 80 PLUS Gold certification guarantees over 90 % efficiency at typical loads, so thermal limits are reached before the electrical rating is exceeded.

How loud and hot does the PSU get during all-day operation?

Cybenetics Standard + noise rating and over 90 % efficiency keep both fan noise and waste heat low even under continuous load.
