In the era of rapid PC hardware performance iteration, 750W modular gold power supplies have become the mainstream choice for mid-to-high-end system builds. With 80 Plus Gold certification (efficiency ≥90% under typical load), flexible modular cabling, and support for standards like ATX3.1/PCIe5.1, these PSUs perfectly balance energy efficiency, expandability, and hardware compatibility. Take GAMEMAX's 750W modular gold PSU lineup as an example—models such as GX PRO 750G, RGB PRO 750G, and GS 750G cater to full-scenario needs from gaming rigs to workstations, achieving dual breakthroughs in efficiency and stability through LLC+DC-DC topology.
All GAMEMAX 750W modular gold PSUs adopt APFC+LLC resonant+DC-DC synchronous rectification design, with efficiency reaching over 90% under typical load. The GX PRO 750G, for instance, uses an MPS1213 chip to optimize the LLC resonant circuit, combined with 180° phase-shift DC-DC control technology, reducing 3.3V/5V output ripple noise to an industry-low level and effectively preventing hardware issues like blue screens or instability caused by voltage fluctuations. As an SFX-form factor PSU, the GS 750G achieves compatibility between 90% efficiency and a compact size through Japanese NCC/KEMET capacitors, making it suitable for small-form-factor scenarios like ITX cases.
With the popularization of RTX 40-series graphics cards and AMD Radeon 7000-series, native support for the PCIe5.1 12V-2×6 interface has become a standard for PSUs. Models like GAMEMAX RGB PRO 750G and GX-750 PRO BK feature built-in 16-pin native interfaces, directly providing 600W peak power for RTX 4090 and similar graphics cards to avoid conversion losses. Meanwhile, the surge current protection mechanism under the ATX3.1 standard addresses scenarios where graphics card transient power consumption spikes, enhancing system reliability.
The fully modular cable design (e.g., GX 750GF) allows users to connect only necessary cables, reducing redundant cabling in the case and improving cooling efficiency. Paired with a 140mm ARGB fan (e.g., RGB PRO 750G) or FDB liquid bearing fan (e.g., GX PRO 750G), intelligent temperature control strategies achieve an operation mode of "silent at low load, cool at high load," with noise controlled below 28dB—ideal for silent PC builds.

| GX PRO 750G | 750W | 80+ Gold | Fully modular design, APFC+LLC+DC-DC, supports ATX3.1/PCIe5.1, 10-year warranty | High-end gaming PCs, workstations |
| RGB PRO 750G | 750W | 80+ Gold | 140mm ARGB fan synchronization, native PCIe5.1 interface, adaptive fan speed control | RGB-themed builds, eSports setups |
| GS 750G | 750W | 80+ Gold | SFX compact form factor, Japanese capacitors, intelligent cooling system, suitable for ITX/Mini-ATX cases | Small high-performance PCs, HTPC |
| GX 750GF | 750W | 80+ Gold | Compact modular design, LLC+DC-DC technology, 92% peak efficiency, FDB silent fan | Mainstream gaming PCs, multi-drive platforms |
| GX-750 PRO BK | 750W | 80+ Gold | Dedicated ATX3.1 model, direct PCIe5.1 12V-2×6 interface for RTX 40-series GPUs, LLC chip-optimized resonant circuit | Professional GPU workstations, overclocking platforms |
For platforms with hardware like i7/i9 + RTX 4070 Ti, 750W power allows a 20%-30% redundancy to avoid efficiency degradation under high load. GAMEMAX products generally exceed 92% efficiency at 50% load, saving approximately 50 kWh per year compared to silver-rated PSUs—ideal for users who keep their systems running long-term.
Beyond the motherboard 24-pin and CPU 8+4-pin interfaces, GAMEMAX PSUs typically offer 4-6 PCIe 6+2-pin interfaces and 8-10 SATA interfaces, supporting multi-GPU/RAID setups. The configuration of native PCIe5.1 interfaces ensures no need to replace the PSU for hardware upgrades over the next 3-5 years.
The GX PRO series uses all-solid capacitors and 105℃ high-temperature-resistant components, paired with sixfold protection (overvoltage/overcurrent/short circuit/undervoltage/overpower/overtemperature). The 10-year warranty policy (e.g., GX PRO 750G) reflects the brand’s confidence in product longevity, suitable for users seeking long-term use.
Case 1: RGB-Themed Gaming PC
Configuration: i9-13900K + RTX 4080 + 3×M.2 + 4×SATA drives
Using RGB PRO 750G, ARGB fan lighting syncs with the motherboard, while fully modular cables enable hidden cabling. With dynamic power response under ATX3.1, it handles the GPU’s 450W transient power without issue, maintaining PSU temperature below 45℃ during stress testing.
Case 2: Compact Workstation
Configuration: Ryzen 9 7950X + RTX 4070 + 2×NVMe + 8×SATA drives
Choosing the GS 750G SFX PSU installed in a JONSBO D30 case, Japanese capacitors ensure voltage stability during simultaneous multi-drive read/write operations. With 90% efficiency, standby power consumption is only 1.2W, suitable for 7×24-hour operation scenarios.
As seen in GAMEMAX’s product lineup, 750W modular gold PSUs have evolved from mere power suppliers to core system components integrating efficiency, compatibility, expandability, and silence. For mainstream gamers, the GX PRO 750G’s 10-year warranty and all-around performance make it an "all-in-one" choice; while users pursuing lighting effects or compact designs will find RGB PRO 750G and GS 750G setting cost-effective benchmarks in ATX and SFX segments, respectively. With the popularization of PCIe5.1 and ATX3.1 standards, choosing a PSU with native support for new specifications will be crucial for future hardware upgrades.
