Core PSU Requirements for RTX 4080 Super

As a high-end graphics card, the NVIDIA GeForce RTX 4080 Super demands the following core power supply configurations:


  1. Rated Power: Officially recommended to pair with 850W or higher PSUs. Considering power consumption from the CPU, memory, and other components, a 1000W PSU is advisable for stable operation.

  2. Interface Support: Require a native PCIe 5.1 16-pin (12V-2x6) connector for 12VHPWR supply, avoiding power loss from adapters.

  3. Efficiency Certification: Opt for PSUs with 80 Plus Gold or higher certification. High-efficiency designs reduce heat and noise, especially for prolonged heavy loads.

  4. Power Supply Standard: Support for ATX 3.1 specification, which handles the GPU’s transient peak power demands to prevent supply fluctuations.

II. Key Dimensions for Selecting a Compatible PSU

  1. Power Headroom and Stability
    The RTX 4080 Super has a typical TDP of ~320W. When paired with an Intel i9 or AMD Ryzen 9 CPU, total system power consumption may exceed 600W. A 30% power buffer is essential—e.g., a 1000W PSU ensures stability during overclocking or multi-tasking.

  2. Connectivity and Compatibility

    • PCIe 5.1 Interface: A native 12V-2x6 (16-pin) connector is mandatory. Models like GameMax RGB PRO 1300P and GX PRO 1250G offer direct support, eliminating adapter risks.

    • Modular Design: Fully or semi-modular PSUs (e.g., RGB PRO 1050G) reduce cable clutter, optimizing case airflow and cable management.

  3. Efficiency and Cooling Design
    80 Plus Gold/Platinum certified PSUs achieve >90% efficiency under typical loads, paired with LLC+DC-DC topologies (e.g., GX PRO series) to minimize conversion losses. FDB fluid dynamic bearing fans (e.g., GX 850GF) support intelligent temperature control, keeping noise below 30dB under high loads.

III. GameMax PSU Recommendations for RTX 4080 Super

The following models from GameMax’s official product line meet ATX 3.1, PCIe 5.1 standards, and power requirements:

1. RGB PRO 1300P - 1300W 80 Plus Platinum

  • Core Advantages: 1300W high power headroom, native support for ATX 3.1 and PCIe 5.1, >92% efficiency under typical loads. ARGB-synchronized fans balance performance and lighting.

  • Technical Highlights: Adaptive Fan intelligent temperature control stops the fan under low loads and adjusts speed gradually under high loads, ensuring excellent noise control.

2. GX PRO 1250G - 1250W 80 Plus Gold
  • Core Advantages: Fully modular design, APFC+LLC+DC-DC circuit architecture, 90% efficiency with silent operation. Japanese capacitors enhance durability, ideal for high-end builds.

  • Compatibility: Native 12V-2x6 connector for direct RTX 4080 Super connection, backed by a 10-year warranty.

3. RGB PRO 1050G - 1050W 80 Plus Gold
  • Core Advantages: 1050W balances performance and cost, ATX 3.1 support for GPU peak power. 140mm ARGB fan syncs with motherboards, suitable for lighting-focused builds.

  • Detail Design: Single +12V rail with high current output stabilizes simultaneous high loads on GPU and CPU.

4. GX PRO 850G - 850W 80 Plus Gold
  • Core Advantages: 850W meets official minimum recommendations, fully modular design saves space. FDB fan noise <25dB, ideal for compact cases.

  • Technical Specs: LLC resonant circuit + DC-DC conversion keeps voltage ripple within ±1%, ensuring hardware stability.

IV. Installation and Compatibility Notes

  1. Interface Check: Ensure the PSU has a 16-pin (12V-2x6) PCIe 5.1 connector; avoid PCIe 4.0 adapters (risk of under-voltage throttling).

  2. Cable Length: Full-tower cases require PSU cables ≥55cm (e.g., RGB PRO series) to prevent tight cabling that affects connectivity.

  3. Cooling Environment: Position the PSU fan toward the case’s ventilation path, avoiding close proximity to the GPU backplate to prevent hot air recirculation.

V. Conclusion

Selecting a PSU for RTX 4080 Super prioritizes "high power, modern interfaces, and high efficiency". GameMax’s RGB PRO and GX PRO series meet ATX 3.1, PCIe 5.1 standards and 80 Plus certifications, combining modular design and silent cooling for reliable support. Choose a ~1000W model based on system configuration to balance stability and future upgradability.
