550 W ATX Bronze power supply

The ASRock Challenger CL-550B delivers 550 W of continuous power through a non-modular ATX design. It carries 80 PLUS Bronze certification and uses a single 120 mm golf-blade fan for cooling. A built-in 5 V boost function helps maintain stable voltage on the minor rail. The unit includes a five-year manufacturer warranty.

Entry-level builders and basic upgrades

This supply suits builders assembling a mid-range system with a single graphics card and a handful of drives. It provides one 24 pin ATX connector, one 8 pin EPS connector, two 8 pin PCIe connectors and four SATA connectors. Systems that require fully modular cabling, higher wattage headroom or more PCIe power leads should consider a different model.

Connector count and case clearance

Verify that your motherboard uses a standard 24 pin ATX and an 8 pin EPS socket. Confirm the graphics card needs no more than two 8 pin PCIe plugs. Ensure the chassis can accommodate a non-modular cable bundle and a 120 mm fan profile. Check that four SATA power plugs cover your storage devices.

Spørgsmål om denne vare

Will the 550 W unit supply enough power for a mid-range graphics card and a modern CPU?

The 550 W rating and 80 PLUS Bronze efficiency give headroom for typical mid-range builds with one graphics card and a current processor.

Does the non-modular cable set include the connectors my motherboard and GPU need?

The fixed cables provide one 24-pin ATX, one 8-pin EPS split as 4+4, two 8-pin PCIe split as 6+2, and four SATA plugs.

How loud is the 120 mm golf-blade fan under load?

The 120 mm golf-blade fan is designed for quiet airflow; noise stays low at typical loads and rises only when the unit approaches its maximum output.
