Made for the
Future
Built for
the power-hungry demands of 2025 and beyond, the MSI MPG A1250GS
features dual native 12V-2x6 connectors, delivering uninterrupted
power to next-generation GPUs and high-performance systems. As
PCIe 5.1 and ATX 3.1 compliant interfaces, these connectors ensure
direct, stable power delivery, reducing reliance on bulky adapters
and mitigating potential power fluctuations
Semi Digital
Integrated Circuit
This 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
Capacitors
The 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.
Master Class
Certifications
Achieving
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
Gold
Beyond
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 Gold
Reserved
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 Gold
A 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.
Zero Fan
Mode
The 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.
Braided
Sleeves
The 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 Connectors
The 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 Clips
To 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 Cable
The
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.
