Main Specifications

Electrical Specifications

*The +3.3 V and +5 V rails share a combined 130 W limit. The +12 V single rail can provide up to 62 A / 744 W, making it the primary high-power rail for the CPU and graphics subsystem.

Connectors

• 1 × ATX 24-pin motherboard connector
• 1 × EPS 4+4-pin CPU connector
• 2 × PCIe 6+2-pin graphics-card connectors
• 5 × SATA power connectors
• 3 × 4-pin Molex connectors
• Non-modular fixed cabling
• Flat cable design for easier cable routing and installation

Cooling & Silent Operation

The MPB750SIW uses a 120 mm SI Extreme Silence fan with FDB bearings. Its AI2-RPM intelligent control system dynamically adjusts fan speed according to system load, aiming to provide the required cooling while minimizing unnecessary fan noise. The published maximum noise level is 12 dB.

Power Conversion & Efficiency

The power supply incorporates DC-DC conversion for improved voltage regulation and energy conversion, together with SMD manufacturing technology. Its 80 PLUS Bronze 230V EU certification corresponds to an efficiency rating of up to approximately 90%, while Active PFC improves the quality and efficiency of power delivery.

Protection Systems

The MPB750SIW incorporates multiple electronic protection mechanisms:

• OCP — Over Current Protection
• OVP — Over Voltage Protection
• UVP — Under Voltage Protection
• OPP — Over Power Protection
• SCP — Short Circuit Protection

These protections are intended to safeguard the power supply and connected PC components against abnormal electrical conditions.
