Supercharged Performance

Semi Digital Integrated CircuitThis power supply features an integrated circuit (IC) for PFC and LLC control, dynamically fine-tuning power factor correction and the LLC resonant converter. This advanced regulation system significantly improves power delivery accuracy, ensuring efficient, real-time adjustments to maintain stable performance for high-end components.

Server Grade CapacitorsThe 105°C capacitors used in the PSU are built to last, withstanding high temperatures for long periods. Known for their reliability, these capacitors ensure consistent power delivery, reduce ripple, and help extend the lifespan of your PSU, even under heavy use.
Golden Greatness
Master Class CertificationsAchieving 80 PLUS Gold, Cybenetics Gold, and PPLP Gold certifications, the MPG A1250GS represents the pinnacle of power supply engineering. Designed for absolute efficiency, it minimises energy waste, reduces heat output, and delivers unwavering stability for the most demanding systems.

Cybenetics GoldBeyond just efficiency, this certification assesses real-world PSU performance, considering acoustic levels, internal component quality, and thermal management. It ensures consistent, high-grade operation under any workload.

80 PLUS GoldReserved for high-efficiency power supplies, this certification ensures 90% efficiency at 50% load, cutting down on wasted energy and reducing overall power consumption compared to standard units.

PPLP GoldA seal of power stability, this certification verifies precise voltage regulation during sudden power shifts, delivering clean, uninterrupted energy and eliminating fluctuations that could disrupt performance-driven systems.
Quieter Than Ever

Zero Fan ModeThe double ball bearing fan is designed for longevity and quiet operation, ensuring smooth and reliable cooling. With Zero RPM mode enabled, the fan stops completely when the TDP is below 55%, reducing noise and power consumption during light loads.
Cable Control

Braided SleevesThe soft braided modular cables are built to last with thick, durable braiding that adds both strength and a premium look. These cables are designed to resist wear and tear, keeping your build clean and flexible.

Dual Colour 12V ConnectorsThe 12V 2x6 cables come with a yellow connector to easily show when they are securely plugged in, helping prevent any issues that could arise from improper connections. This simple design ensures peace of mind during installation.

Cable ClipsTo keep everything organised, the included cable organiser with its sleek finish ensures that your cables stay neat and tidy. It not only enhances the look of your system but also improves airflow by reducing cable clutter inside your case.

Safety CableThe high-density, fully UL certified covered copper wire (known as the safety cable), ensures safe and secure connections, while the robust cooling setup allows the PSU to handle demanding tasks without overheating.
