• PCIe 5.0 M.2 Support
• Four M.2 Storage Slots
• WiFi 7
• Realtek 2.5Gb Ethernet
• USB4 40Gbps Type-C
• AMD EXPO Support

This provides a modern platform with strong connectivity and future upgrade potential.

32GB XPG CASTER RGB DDR5-6000

The build includes 32GB of XPG CASTER RGB DDR5 memory, configured as a 2×16GB dual-module kit running at 6000MT/s CL40.

The corresponding CASTER RGB configuration is rated at:

• 32GB Total Capacity
• 2 × 16GB Modules
• DDR5-6000
• CL40
• 40-40-40 Timings
• 1.35V
• RGB Lighting
• Intel XMP 3.0
• AMD EXPO Support

This provides plenty of capacity and memory bandwidth for gaming, multitasking, productivity, and creative workloads.

SAPPHIRE PURE Radeon RX 7800 XT 16GB

Graphics performance is powered by the SAPPHIRE PURE AMD Radeon RX 7800 XT 16GB, based on AMD RDNA 3 architecture.

The card features:

• 3840 Stream Processors
• 60 Compute Units
• 60 Ray Accelerators
• 16GB GDDR6
• 256-Bit Memory Interface
• 19.5Gbps Memory Speed
• 64MB Infinity Cache
• Game Clock up to 2169MHz
• Boost Clock up to 2475MHz
• PCI Express 4.0 x16
• DisplayPort 2.1
• Triple-Fan Tri-X Cooling

The large 16GB VRAM capacity makes the RX 7800 XT particularly suitable for high-resolution gaming, detailed textures, and graphics-intensive applications.

SAPPHIRE PURE White Design

The PURE series uses SAPPHIRE’s distinctive light-colored cooling shroud, triple-fan thermal design, metal backplate, and illuminated SAPPHIRE logo.

This gives the graphics card a clean premium appearance while providing substantial cooling for the RX 7800 XT GPU.

XPG BATTLECRUISER Super Mid-Tower

The system is housed inside the XPG BATTLECRUISER Super Mid-Tower chassis, providing a spacious layout for high-performance hardware and cooling.

The BATTLECRUISER supports:

• E-ATX / ATX / Micro-ATX / Mini-ITX Motherboards
• Four Included 120mm Fans
• Tempered Glass Panels
• Up to 400mm Graphics Card Clearance
• Up to 170mm CPU Cooler Clearance
• Front Radiators up to 360mm
• Top Radiators up to 360mm
• USB Type-C
• Vertical GPU Installation Support

The spacious chassis provides plenty of room for the large SAPPHIRE graphics card and high-performance cooling hardware.

Cooler Master Dual-Fan CPU Cooling

CPU cooling is handled by a Cooler Master MasterAir MA612 dual-fan air cooler.

The MA612 family uses a performance-focused tower cooler design and Cooler Master officially lists the MA612 Stealth as compatible with AMD AM5 through its socket compatibility program.

850W Power Supply

The system uses a XIGMATEK ASGARD 850W 80+ Bronze power supply.

The 850W capacity provides additional power headroom for the CPU, graphics card, cooling, and other system components.

SAPPHIRE officially specifies a minimum 700W power supply for the PURE RX 7800 XT, so the supplied 850W unit exceeds the GPU manufacturer’s minimum wattage recommendation.
