GameMax RPG Rampage 750W Fully Modular 80 Plus Bronze PSU
The GameMax RPG Rampage is a 750W fully modular power supply designed for PC builders who want clean cable management and reliable power delivery without paying premium prices. It uses a single 12V rail, Japanese capacitors, and 80 Plus Bronze certification to handle mid-to-high-end gaming rigs efficiently.
Why this product
Fully modular cabling
Every cable disconnects, leaving only what you need connected. This cuts clutter inside your case, improves airflow, and makes upgrades and rebuilds much faster.
80 Plus Bronze certified
Achieves up to 88% efficiency at 50% load, meaning less wasted heat and lower electricity bills over the lifetime of the unit.
Japanese TK main capacitor
Rated for 100,000 hours MTBF, this component underpins reliability and long service life.
Single 12V rail
Delivers high current output with broad compatibility across modern GPUs and CPUs without rail-sharing conflicts.
14cm ultra-silent fan
Runs at 40 dB to keep cooling effective without audible noise during normal gaming and office use.
2-year warranty
Full manufacturer coverage for 24 months from purchase.

Trade-offs
- Systems requiring more than 750W (dual high-end GPUs, CPU+GPU workstation loads)
- Extreme enthusiasts expecting 90%+ efficiency — 80 Plus Bronze peaks at 88%, placing it below Gold-rated units
- Data centre or 24/7 continuous-load deployments — 100,000 hours MTBF is consumer-grade, not enterprise-grade
- Buyers needing warranty beyond 2 years
