Micro ATX Power Supply GAMEMAX

The Core Value and Market Positioning of Micro ATX Power Supplies

In the upsurge of compact PC builds, Micro ATX power supplies have become the core components for mini hosts, HTPCs, and high-performance small-form-factor cases, thanks to their "small size, high integration" characteristics. Compared with standard ATX power supplies, their dimensions are typically reduced by over 30% (e.g., SFX specifications are 125×100×63.5mm), yet they need to achieve equivalent or even higher power density within limited space. As an innovative brand in the power supply sector, GAMEMAX's SFX and TFX series power supplies for Micro ATX scenarios balance space constraints and performance requirements through 80 Plus certifications, modular designs, and silent technologies, making them ideal for users pursuing "small yet powerful" PC build solutions.

II. In-Depth Analysis of GAMEMAX Micro ATX Power Supply Technologies

1. Efficiency and Certification: Dual Guarantees for Energy Saving and Stability

GAMEMAX's Micro ATX power supplies prioritize high conversion efficiency. For example:

• The GS series SFX power supplies (such as GS-850G BK and GS-750G BK) are all 80 Plus Gold certified, with efficiency exceeding 90% under typical loads. Equipped with high-quality Japanese capacitors, they reduce ripple interference, ensuring stable power supply for CPUs and GPUs. Their LLC resonant + DC-DC circuit design controls the 12V output ripple within 50mV, far below industry standards, making them suitable for high-frequency hardware with strict voltage stability requirements.

• The TFX series Platinum-grade power supplies (such as GT-450P BK) achieve 80 Plus Platinum certification, with peak efficiency reaching 92%, realizing "low power consumption, high output" in the 450W power segment—particularly suitable for the energy-saving needs of mini hosts in long-term operation.

2. Cooling and Silence: The Philosophy of Cool Operation in Small Sizes

Addressing the heat dissipation challenges of Micro ATX power supplies, GAMEMAX employs differentiated designs:

• Intelligent fan control: The GS series features FDB (Fluid Dynamic Bearing) fans that dynamically adjust speed through temperature sensors, achieving "zero noise" operation under low loads and controlling noise within 28dBA under high loads—outperforming most 同类 products (similar products).

• Compact cooling structure: The TFX power supply (such as GT-300G WH) uses an 80mm silent fan combined with an all-aluminum heatsink, enabling efficient heat conduction within a volume of 175×85×65mm to avoid heat accumulation in small cases.

3. Compatibility and Expandability: Adapting to Future Hardware Ecosystems

With the popularization of PCIe 5.1 and ATX 3.1 standards, some GAMEMAX Micro ATX power supplies have made forward-looking arrangements:

• The GS-850G BK supports native 12V-2×6 interfaces, directly compatible with the 16pin power supply requirements of RTX 40-series graphics cards, avoiding losses from adapters;

• The modular design (such as GS-650G BK) allows users to connect only necessary cables, reducing cable clutter in small cases and improving cooling efficiency.

III. Key Selection Criteria and Scenario Matching for Micro ATX Power Supplies

1. Power Calculation: Matching Hardware Requirements as Needed

• Office/HTPC hosts: 300-500W (e.g., GT-300G WH, GS-450 BK), suitable for i5-class CPUs + integrated graphics or entry-level discrete graphics;

• Gaming mini hosts: 650-850W (e.g., GS-750G BK, GS-850G BK), compatible with i7/Ryzen 7 + RTX 3070-class graphics cards;

• Extreme small form factor builds: Pay attention to the power supply's single-rail 12V output capability. For example, the GS-850G BK's 12V output accounts for 99%, fully unleashing the performance of high-end hardware.

2. Certification and Component Quality: Determinants of Hidden Performance

• 80 Plus certification levels directly impact electricity costs: A Gold-certified power supply can save approximately 50 kWh per year compared to a Bronze one;

• Japanese capacitors (such as Nichicon, Teapo) and full-bridge LLC architectures ensure long-term stability. The GAMEMAX GS series all use 105℃ high-temperature resistant capacitors with a lifespan of over 100,000 hours.

3. Size and Case Compatibility

• SFX power supplies require cases supporting SFX specifications (e.g., Lian Li Q58, SilverStone SG14);

• TFX power supplies are more suitable for ultra-thin cases (e.g., JONSBO V4), but pay attention to the positional compatibility with the motherboard's power interface.
