With the rise of next-gen hardware like RTX 40-series graphics cards and Ryzen 7000 processors, PC power supplies face unprecedented challenges: surging transient peak power, growing PCIe 5.0 interface demands, and stricter efficiency/stability standards. As an early adopter of the ATX 3.0 specification, GAMEMAX introduces a full-spectrum lineup of ATX 3.0 power supplies, leveraging cutting-edge technology to redefine premium power solutions.
The ATX 3.0 specification addresses two critical pain points: transient overload protection and next-gen hardware compatibility.
2x Transient Power Support: Enables up to 200% instantaneous power output (e.g., a 1000W PSU can deliver 2000W transient power), effortlessly handling the sudden power spikes from PCIe 5.0 graphics cards to prevent system crashes caused by voltage drops.
Native PCIe 5.1 Support: Features a 16-pin 12V-2×6 native connector to directly supply 600W pure power to GPUs like the RTX 4090, eliminating adapter cable losses and enhancing stability.
Efficiency & Silence Revolution: Combines LLC resonant + DC-DC circuit designs with 80 Plus Gold (or higher, in select models) certification, achieving over 90% efficiency at typical loads. Smart fan 启停 technology ensures near-silent operation under low loads.
GAMEMAX offers three core series to meet diverse user needs, covering everything from flagship builds to compact ITX setups:
Models: RGB PRO 1300P (1300W, 80 Plus Platinum), RGB PRO 1050G (1050W, 80 Plus Gold)
Key Advantages:
Platinum-Grade Efficiency: The 1300P achieves 92%+ efficiency at typical loads, saving energy and reducing heat. A 140mm ARGB smart fan accelerates cooling under high loads and stops completely at low loads for silent operation.
Fully Modular Design: Allows users to select only necessary cables, enabling clutter-free cable management and improved airflow—ideal for high-end side-panel showcase builds.
Future-Ready Compatibility: Native support for ATX 3.1 and PCIe 5.1, with a single 12V rail delivering up to 108A (1300P), effortlessly powering multi-GPU setups or overclocked CPUs.
Models: GX PRO 850G (850W, 80 Plus Gold), GX PRO 750G (750W, 80 Plus Gold)
Key Advantages:
Balanced Performance: 90% typical efficiency with APFC+LLC+DC-DC triple architecture, keeping 3.3V/5V output ripple within 50mV to protect sensitive components like SSDs and motherboard chipsets.
Quiet Operation: FDB liquid-bearing fan with intelligent speed control keeps noise below 30dB at full load—quieter than most mechanical hard drives.
Durability First: Japanese 105℃ electrolytic capacitors + full-bridge LLC resonant circuit ensure 100,000+ MTBF (Mean Time Between Failures), backed by a 10-year warranty—well above industry standards.
Models: GS 850G (SFX form factor, 80 Plus Gold), GX 650GF (compact ATX, 80 Plus Gold)
Key Advantages:
Small Size, Big Power: The GS 850G measures just 125mm in length, perfect for ITX cases or HTPCs, supporting backside cable routing. The GX 650GF integrates fully modular connectors into a 140mm body, compatible with 90% of mainstream cases.
Stability in Tight Spaces: Features a smart thermal algorithm with 1℃-precision fan 启停 thresholds to avoid frequent cycling, plus quadruple protection (over-voltage, under-voltage, short-circuit, over-load).
Power Calculation: Use the formula “CPU + GPU TDP × 1.5x”. For example, RTX 4070 (200W) + i7-14700K (125W) requires at least a 650W PSU; overclockers should add 100-200W.
Certification & Efficiency: Opt for 80 Plus Gold (90% efficiency) for gaming rigs, or Platinum (92%+) for 极致 energy savings. Bronze (85%) works for office PCs, but verify transient power support.
Connectivity Needs: Ensure a native 16-pin PCIe 5.0 connector (not an adapter). Multi-GPU users need sufficient PCIe cables; ITX builders should prioritize SFX or short-body ATX PSUs.
Technical Expertise: 20 years of experience in power supply design, continuously updating with Intel’s PSU guidelines to ensure 100% hardware compatibility.
Rigorous Testing: Every unit undergoes 32 tests, including 120℃ high-temperature aging, 24-hour full-load stress testing, and surge voltage 冲击，with a failure rate <0.1% in extreme conditions.
Ecosystem Integration: ARGB fans support 主流 motherboard lighting sync (ASUS Aura Sync, MSI Mystic Light), with modular cables available in black/white for custom builds.
As hardware performance enters a new era, the PSU is no longer an afterthought—it’s the “heart” of your PC, dictating system stability, component lifespan, and energy efficiency. GAMEMAX’s ATX 3.0 lineup, spanning 450W to 2000W, Gold to Platinum efficiency, and full-modular to compact SFX form factors, offers “future-proof” solutions for all scenarios. Whether building a high-performance gaming beast or a sleek living-room HTPC, GAMEMAX proves with technological innovation that a true premium PSU must both “feed” and “protect” your hardware.
