Description
The MSI MPG A1250GS PCIE5 is a high-performance power delivery solution engineered to meet the rigorous demands of next-generation computing. Adhering to the latest ATX 3.1 and PCIe 5.1 standards, this unit is capable of handling massive power excursions up to 235% of its rated capacity. Its compact 150mm depth ensures broad compatibility with various chassis sizes while maintaining superior cooling through a 135mm Fluid Dynamic Bearing fan, making it a cornerstone for any high-end PC build.
This product is for:
- Enthusiast gamers building rigs with NVIDIA GeForce RTX 50 series or high-end 40 series GPUs.
- Professional content creators requiring stable power for multi-GPU setups and high-core-count CPUs.
- PC builders prioritizing clean aesthetics and easy cable management via embossed flexible modular cables.
- Users seeking long-term investment security with a 10-year warranty and industrial-grade protections.
- Overclockers who need consistent voltage regulation and high-temperature resilience from 105°C Japanese capacitors.
Detailed specifications:
- Form Factor: ATX 3.1 / PCIe 5.1
- Total Wattage: 1250W (Peak Power Excursion: 2937W)
- Efficiency: 80 PLUS Gold (Up to 90%)
- Cooling: 135mm Fluid Dynamic Bearing (FDB) Fan
- Dimensions: 150 x 150 x 86 mm
- Connectors: 1x 24-pin ATX, 2x 4+4-pin EPS, 2x 16-pin (12V-2x6) 600W, 1x 6+2-pin PCIe, 8x SATA, 4x Molex
- Protection: OCP, OTP, OPP, SCP, OVP, UVP, SIP, NLO
Installing the MPG A1250GS is streamlined by its fully modular design and exceptionally soft embossed cables, which bend easily around tight corners in the chassis. The dual-color 12V-2x6 cables provide a visual confirmation of a secure connection, preventing common seating issues with high-power GPU headers. During heavy workloads, the 135mm fan remains whisper-quiet, adjusting its speed dynamically based on thermal load without the intrusive clicking often found in lower-tier bearings.
Compared to standard ATX 3.0 units, the MPG A1250GS adheres to the stricter ATX 3.1 standards, offering improved reliability for the 12V-2x6 interface. While many 1200W+ power supplies exceed 160mm in length, this unit’s 150mm depth provides significantly more room for cable management in mid-tower cases. It offers a more robust protection suite, including SIP and NLO, than entry-level gold-rated units, placing it firmly in the premium enthusiast category.
Q&A:
- Does this power supply support the upcoming NVIDIA RTX 50 series? Yes, it features native PCIe 5.1 and dual 12V-2x6 connectors specifically designed for next-gen high-power graphics cards.
- What is the benefit of the dual-color cable design? The dual-color 12V-2x6 cable helps users ensure the connector is fully inserted into the GPU, reducing the risk of thermal damage from loose connections.
- Is this PSU compatible with older motherboards? Yes, it includes standard 24-pin ATX and 4+4-pin EPS connectors compatible with previous generations of hardware.
- How does the 135mm FDB fan compare to standard fans? Fluid Dynamic Bearings offer a longer lifespan and quieter operation than sleeve or ball-bearing fans by reducing friction and vibration.
- Can I use this in a small form factor case? While it is an ATX PSU, its 150mm length is relatively compact for its wattage, making it suitable for many compact ATX and mid-tower cases.
