GAMEMAX 750W 80 Plus Gold power supplies are priced in three tiers based on features:
Entry-Level Modular Models: e.g., RGB 750G, starting at $60-$80 for basic gaming setups.
Mainstream All-Rounders: GX PRO 750G, GX 750GF, priced $80-$120 for balanced performance, silence, and expandability.
Flagship SFX Models: GS 750G, $120-$150 for high-end small-case configurations.
Value Recommendation: Choose RGB 750G for tight budgets; prioritize GX PRO 750G for future compatibility; opt for GS 750G for mini PC builds.
Take a 750W power supply driving a mainstream gaming config as an example:
Typical Configuration: Intel i7-13700K/AMD Ryzen 7 7700X + RTX 4070/RTX 3080 + 32GB DDR5 RAM, with full-load power consumption of ~550-650W—leaving 20% headroom in a 750W supply.
Cable Management: Modular power supplies only connect essential cables (24Pin motherboard, 8Pin CPU, 16Pin GPU), improving case airflow by 15%-20% with backline designs.
Cooling Optimization: Models supporting low-load fan stop (e.g., GX 750GF) keep noise below 20dB during nighttime gaming.
GAMEMAX's 750W 80 Plus Gold power supply lineup caters to all needs:
For ultimate performance and future-proofing, the GX PRO 750G with ATX3.1 + PCIe5.1 is the top choice.
Gamers seeking lighting and modularity will love the RGB PRO 750G's ARGB fan and full modular design.
Small-case builders should opt for the GS 750G, delivering ATX-level stability in an SFX form factor.
