GAMEMAX ATX 3.1 Power Supply, a Tailored Power Core for RTX 40/50 Graphics Cards

In the wave of PC hardware iteration, the power supply—known as the "power heart" of the entire system—has become increasingly crucial. With the popularization of RTX 40-series graphics cards and the upcoming launch of RTX 50-series, traditional power supplies can hardly meet the new hardware’s demands for power stability, efficiency, and interface compatibility. The introduction of the ATX 3.1 standard perfectly addresses this pain point. As a world-renowned PC hardware brand, GAMEMAX leverages its strong R&D capabilities to launch a range of power supply products compliant with the ATX 3.1 standard, covering multiple series including RGB PRO, GX PRO, GZ, and LION CORE. Spanning power ratings from 850W to 1300W, these products fully cater to diverse PC building needs, allowing gamers to seamlessly embrace the next-gen hardware ecosystem.

I. Why Choose an ATX 3.1 Power Supply? The "Must-Have Standard" for Next-Gen PC Builds

ATX 3.1 is not just a simple interface upgrade; it is a comprehensive optimization tailored to the power requirements of modern PC hardware—especially high-performance graphics cards. Its core advantages focus on three dimensions:

1. Native PCIe 5.1 Support, Eliminating "Adapter Anxiety"

RTX 40/50-series graphics cards adopt the new 12V-2x6 power connector (i.e., PCIe 5.1 standard interface). Compared to traditional 6+2Pin interfaces, it offers higher current-carrying capacity and lower power loss. All GAMEMAX ATX 3.1 power supplies are equipped with a native 12V-2x6 connector, enabling "seamless connection" with new graphics cards without relying on adapter cables. This not only avoids current loss caused by adapters but also reduces heat dissipation dead spots in the chassis due to tangled cables, ensuring full performance release of the graphics card.

2. Enhanced Power Stability to Cope with "Instant High Loads" of Hardware

Modern graphics cards experience instantaneous power fluctuations when running 3A games, AI rendering, and other scenarios (e.g., the instantaneous power of RTX 4090 may exceed 600W). The ATX 3.1 standard imposes higher requirements on the power supply’s "transient response capability." GAMEMAX significantly improves the power supply’s voltage regulation accuracy and anti-fluctuation performance through a combination of Japanese 105℃ high-temperature capacitors and solid-state capacitors. Take the LION CORE 1000P as an example: its 100% Japanese capacitor design maintains stable output under high loads, preventing game lag and hardware restart caused by voltage fluctuations.

3. Dual Upgrades in Energy Efficiency and Quiet Operation, Aligning with the "Green PC Building" Trend

ATX 3.1 power supplies generally adopt more advanced circuit designs (such as GAMEMAX’s APFC+LLC+DC-DC architecture) and are paired with high-level 80 PLUS certifications to balance energy efficiency and quiet operation. For instance, the GAMEMAX RGB PRO 1300P has obtained 80 PLUS Platinum certification, achieving an energy efficiency of over 92% under typical loads. This not only reduces electricity costs but also minimizes the heat generated by the power supply itself. The GX PRO series is equipped with a 13.5cm FDB hydraulic bearing fan and "0dB intelligent temperature control" technology— the fan stops running under low loads and adjusts its speed automatically under high loads, completely eliminating the "noise anxiety" of traditional power supplies.

II. GAMEMAX ATX 3.1 Power Supply Family: A "Power Solution" Covering All Scenarios

To meet the diverse needs of users for PC building, GAMEMAX divides its ATX 3.1 power supplies into four core series. Each series has a clear positioning and unique features, ensuring that whether you are an enthusiast pursuing RGB lighting effects or a productivity user focusing on ultimate stability, you can find a tailored option.

III. "Buying Guide" for ATX 3.1 Power Supplies: Avoid Misconceptions, Choose the Right One Instead of the Most Expensive One

For users planning to upgrade to the ATX 3.1 platform, three core dimensions should be considered when selecting a power supply, avoiding blind pursuit of high power or high certification:

1. Power Selection: "Reserve Margin" Rather Than "The Larger, the Better"

• Mid-range configuration (RTX 4060 + 12400F): 850W is recommended (e.g., GZ 850G) to meet current needs while reserving room for future upgrades;

• High-end configuration (RTX 4080 + 13700K): 1050W-1200W is suitable (e.g., GX PRO 1250G) to cope with power fluctuations under high loads;

• Flagship configuration (RTX 4090/5090 + 13900K): 1300W or above (e.g., RGB PRO 1300P) to ensure stable power supply when hardware operates at full load.

2. Certification and Circuitry: 80 PLUS Gold Is the "Cost-Effective Sweet Spot"

• 80 PLUS Platinum certification (e.g., RGB PRO 1300P) is suitable for users with long-term high-load needs, as it offers more obvious energy efficiency advantages;

• 80 PLUS Gold certification (e.g., GX PRO, GZ series) balances energy efficiency and price, making it the first choice for most users;

• Priority should be given to products adopting the APFC+LLC+DC-DC architecture, as this circuit design can effectively reduce conversion loss and improve power supply stability.

3. Additional Features: Choose Based on Needs, Reject "Unnecessary Add-Ons"

• Enthusiasts pursuing aesthetics: Prioritize the RGB PRO series, which supports motherboard lighting synchronization to create a unified chassis lighting effect;

• Users seeking quiet operation: The GX PRO (FDB fan) and LION CORE (0dB temperature control) are better choices;

• Users struggling with cable management: Fully modular GX PRO and RGB series can greatly reduce PC building difficulty;

• For long-term use: Prioritize products with Japanese capacitors and long warranties (e.g., LION CORE’s lifetime warranty, GZ series’ 5-year warranty) to reduce long-term maintenance costs.

IV. Conclusion: ATX 3.1 Power Supply—More Than an "Upgrade," It’s a "Future Investment"
