## Long description

The MPB1000PSI Power Supply is a fully modular ATX 3.1 power unit with 1000 W total capacity designed for desktop PC systems. It features 80 PLUS Gold efficiency, Toshin Kyogo 105º Japanese capacitors, a native 12V 2x6 connector with PCIe 5.1 support, and a 140 mm SI Extreme Silence fan with AI2-RPM cooling to balance low noise and effective heat dissipation. Available in black or white, the unit includes modular cabling (with white full cabling on the white version) and supports standard motherboard and peripheral connections for high-end GPU and system configurations.
Advantages
The MPB1000PSI combines high energy efficiency (80 PLUS Gold) with advanced DC-DC conversion and Active-PFC digital control to ensure stable voltages and reduced losses. Its AI2-RPM cooling system dynamically adjusts fan speed using machine learning for quiet operation while the Toshin Kyogo Japanese capacitors and full protection suite provide long-term reliability. The fully modular layout improves cable management and internal airflow, and the native 12V 2x6 connector simplifies power delivery to next-generation graphics cards.
Suitable for
High-performance gaming PCs with modern GPUs
Workstations requiring stable 12 V rails and sustained power delivery
Custom builds where modular cabling and clean airflow are priorities
Systems needing efficient, low-noise cooling and long-term reliability

How to use
Install the MPB1000PSI into a compatible ATX chassis and connect the 24-pin ATX motherboard cable plus the required CPU and peripheral cables to your components. For modern GPUs that require PCIe 5.1 power, use the native 12V 2x6 connector; if your GPU needs a different plug, use an appropriate adapter only when necessary. Ensure the power supply is secured to the case, route modular cables to maintain clear airflow, and connect the AC input to a grounded mains outlet matching the specified voltage range before powering on the system.
Usage recommendations
To maximize longevity and stable performance, mount the power supply in a case with adequate airflow, keep dust to a minimum, and confirm compatibility of the GPU power connector. Use the white model if you require matching white cabling; otherwise, the black version provides a standard aesthetic. Observe the included protections (OCP, OVP, OPP, OTP, OLP, NLO, PFP, UVP, SCP, TCP) and the 10-year warranty terms for safe long-term operation.
