In the era of minimalist gaming setups, the "small steel cannon" (小钢炮) PC has emerged as a symbol of performance in a compact footprint. The AMD Radeon 9070 XT, a powerhouse graphics card, demands a build that balances raw power with spatial efficiency. This guide explores how GameMax's SFX power supplies and compact chassis redefine small-form-factor (SFF) gaming, combining the 9070 XT's brute force with sleek, space-saving design.
No compromise on power or efficiency—enter the GS 850G 80 Plus Gold SFX Power Supply. Tailored for high-end SFF builds, this PSU delivers:
850W of Gold Efficiency: 90%+ efficiency under typical loads, reducing heat and energy waste with LLC & DC-DC technology.
ATX3.1 & PCIe 5.1 Ready: Native 12V-2x6 connector ensures direct, loss-free power delivery to the 9070 XT, supporting peak performance during gaming or rendering.
Japanese Capacitors & Intelligent Cooling: Premium components and a silent FDB fan maintain stability, while comprehensive protections (OVP, UVP, OCP, SCP) safeguard your rig.
SFX Form Factor: At just 125x100x63.5mm, it fits seamlessly into compact cases without sacrificing power.
The Spark Mini BK ITX Case redefines small-scale versatility for 9070 XT builds:
Vertical Airflow Channel: A unique design optimizes cooling, supporting up to 7 ARGB fans and 120mm water cooling radiators to keep the 9070 XT and CPU chill under load.
Tempered Glass Panels: Dual 3mm glass panels showcase your build’s RGB lighting (perfect for syncing with the GS 850G’s optional ARGB fans) and hardware.
Full Compatibility: Despite its tiny footprint (supporting ITX/Micro-ATX motherboards), it fits GPUs up to 340mm—more than enough for the 9070 XT—and offers tool-less cable management.
Portable Design: Lightweight construction with a vertical layout makes it ideal for desktop setups or on-the-go gaming.
Performance in a Pocket:
The 9070 XT thrives in this setup, drawing clean power from the GS 850G to deliver 4K gaming and ray tracing without bottlenecks. The Spark Mini’s airflow ensures temperatures stay within optimal ranges, even during marathon sessions.
Silent Operation, Maximum Efficiency:
The GS 850G’s FDB fan and the Spark Mini’s noise-dampening features create a near-silent system. Gold-certified efficiency reduces heat, while the case’s mesh panels and fan configuration prioritize cool, quiet performance.
Aesthetic Flexibility:
ARGB sync between the PSU (optional models) and case fans, combined with the Spark Mini’s glass panels, lets you craft a visually stunning build. The compact form factor also fits seamlessly into minimalist setups or gaming battle stations.
Future-Proofing:
With ATX3.1 and PCIe 5.1 support, the GS 850G future-proofs your build for next-gen components, while the Spark Mini’s modular design allows easy upgrades to storage or cooling.
The GameMax GS 850G SFX PSU and Spark Mini BK case form the backbone of a 9070 XT small steel cannon build that doesn’t sacrifice performance for size. This combination proves that SFF gaming can match full-tower power while offering portability, aesthetics, and efficiency. Whether you’re a desktop minimalist or a gaming enthusiast seeking a space-saving beast, this setup delivers the best of both worlds—no compromise, all performance.
