As the mainstream model in the mid-range market, 700W power supplies perfectly balance power demand and cost-effectiveness. Typical applications include:
Mid-range gaming desktops: Supports Intel i5/i7 or AMD Ryzen 5/7 processors paired with RTX 3060/RTX 4060, RX 6700 XT and other graphics cards, ensuring stable power supply under high loads.
Multitasking office platforms: Meets requirements for multi-screen output and virtual machine operation, while balancing energy efficiency under low loads.
Small workstations: Provides continuous power for creative scenarios such as light video editing and 3D modeling.
From the perspective of power redundancy, a 700W PSU is recommended for systems with a peak power consumption of no more than 550W, which avoids overload risks and reserves space for upgrades (e.g., adding a second hard drive or graphics card).
Gold vs Bronze:
Gold-certified models (e.g., GameMax GX 700G) achieve over 90% efficiency under typical loads, saving 15%-20% on electricity bills in the long run, ideal for users pursuing energy efficiency and silence.
Bronze-certified models (e.g., GM 700B) offer ~85% efficiency with higher cost-performance, suitable for budget-conscious office setups.
LLC+DC-DC Architecture: The LLC resonant + DC-DC conversion circuit adopted by GX 700G reduces voltage fluctuations and ripple noise, extending hardware lifespan.
Capacitor Quality: Japanese capacitors (e.g., Nichicon, Rubycon) excel in high-temperature resistance, while Taiwanese capacitors (e.g., Teapo) balance cost and performance.
Fan Type: FDB (Fluid Dynamic Bearing) fans (e.g., GX 700G) feature longer lifespan and noise below 25dB; traditional oil-sealed fans require regular maintenance.
Intelligent Temperature Control: Some models (e.g., GM 700B) support low-load fan stop technology, achieving zero noise under light loads.
Fully Modular (e.g., GX 700 BK): Only connect necessary cables to optimize case cooling and cable management;
Semi-modular/Non-modular: Suitable for users with low cable management requirements, offering lower costs.

| Application Scenario | CPU | Graphics Card | Recommended 700W PSU Model | Power Redundancy |
|---|---|---|---|---|
| 1080P High-Quality Gaming | Intel i5-12400F | RTX 3060 | GX 700G | 30% |
| 2K Gaming + Multitasking | AMD Ryzen 7 5800X | RX 6700 XT | GX 700 BK | 25% |
| Office/Home Use | Intel i3-13100 | Integrated/GTX 1650 | GM 700B | 40% |
Gaming and Creative Needs: Prioritize 80+ Gold-certified GX 700G/GX 700 BK for high efficiency and stability; modular design enhances build experience.
Office Use and Cost-Effectiveness: GM 700B’s Bronze efficiency and dual DC-DC circuit suffice for daily loads, with Taiwanese capacitors balancing reliability and cost.
Detail Focus: Check if the PSU supports ATX 3.1/PCIe 5.1 (e.g., GX series natively supports 12V-2x6 connectors) to future-proof upgrades to RTX 40-series GPUs.
As the "golden power segment" in the mid-range market, 700W PSUs evolve around "efficiency, silence, and compatibility". GameMax’s 700W product line caters to diverse needs through differentiated positioning—from Gold efficiency to Bronze cost-performance, from silent design to modular aesthetics—each model embodying the hardware philosophy of "precise power, exceeding expectations".
