Refurbished ABS Challenger mid-tower gaming desktop

This refurbished ABS Challenger ALA278 is a mid-tower desktop built for 1080p gaming and everyday multitasking. It ships with Windows 10 Home 64-bit installed and an AMD Ryzen 5 5600 six-core processor. The NVIDIA GeForce RTX 3050 with 8 GB GDDR6 handles modern titles at medium to high settings. Buyers who need Windows 11 Pro out of the box or more than 512 GB of primary storage should look elsewhere.

B550 chipset, 550 W 80

The system sits on an AMD B550 motherboard inside a Rosewill Zircon I chassis. A 550 W 80 Plus Gold power supply feeds the components, while an AMD stock cooler and two 120 mm case fans manage thermals. Front-panel I/O and rear motherboard ports provide standard connectivity. Builders who want extensive front-panel USB-C or additional drive bays will find the layout limited.

8 GB DDR4 3000 MHz RAM and single M.2 NVMe slot

Memory is a single 8 GB DDR4 3000 MHz module, so dual-channel performance is not active unless a matching stick is added. The 512 GB M.2 NVMe SSD occupies the primary slot; extra storage requires a second M.2 or 2.5-inch drive. Networking covers Gigabit LAN, Wi-Fi 5 and Bluetooth. Verify your monitor inputs match the GPU outputs before ordering.

Questions about this item

What PCIe generation does the B550 chipset provide for the RTX 3050 and the M.2 NVMe SSD?

The AMD B550 chipset runs the graphics slot and the M.2 NVMe SSD at PCIe 4.0 speeds, so the RTX 3050 and the 512 GB drive both operate at the full 4.0 bandwidth the platform supports.

What clearance and power connectors does the Rosewill Zircon I case require for the installed RTX 3050?

The mid-tower chassis fits dual-slot cards up to the length of the supplied RTX 3050, and the 550 W 80 Plus Gold unit includes the single 8-pin PCIe connector the graphics card needs.

How is the 8 GB DDR4 3000 MHz kit installed on the B550 motherboard, and which slot order avoids the common boot failure?

The two modules go into the second and fourth DIMM slots from the CPU socket; populating the first slot instead of the second is the mistake that typically prevents the system from posting.
