A 750 W computer power supply is designed for gaming and versatile mid-range builds where not only performance but also longevity matter. In terms of price, the GameMax GP-B belongs to the affordable segment, yet stands out from competitors with an extended feature set and a five-year warranty, which is usually found in more expensive solutions. The DC-DC converter circuitry uses phase shifting for the 3.3V and 5V rails, reducing ripple and maintaining voltage accuracy within ±2%.

Stability under full load is ensured by TEAPO capacitors manufactured in Taiwan, rated for long-term operation. The cooling system is based on a 140 mm fan with a hydrodynamic bearing, and its speed is automatically adjusted depending on the load, helping to maintain a balance between power consumption and noise levels (25 dB at peak load). To improve heat dissipation, a double-sided PCB with top-mounted components and aluminum heatsinks is additionally used.

Special attention deserves the protection set: in addition to the standard OVP, OPP, SCP, and UVP, it also implements OCP, OTP, as well as NLP, SIP, OLP, and NLO. This comprehensive approach ensures multilayer safety and protects components even in atypical scenarios. Overall, the GameMax GP-B looks like a balanced choice for those who want a power supply with power headroom, stable circuitry, and long service life, and it will be an excellent option for mid-power builds with Core i7/Ryzen 7 processors and graphics cards like the GeForce RTX 4070/Radeon RX 7800 XT.
