Pros
- Delivers up to 600W of power through its native 12V-2x6 PCIe 5.1 connector, supporting NVIDIA's 50 series graphics cards.
- Features ATX 3.1 compliance, allowing for up to 220% total power excursion and 3x GPU power excursion.
- Achieves 80 PLUS Gold certification with up to 90% energy efficiency.
- Maintains low noise operation with a 135 mm Fluid-dynamic bearing (FDB) fan.
- Comes with a compact 150 mm length and 150 mm width ATX form factor for easier case integration.
- Includes embossed jacket cables for improved bending and routing, aiding cable management.
Cons
- The 10-year warranty stated in the product title contradicts MSI's official product page which lists a 7-year warranty.
- No specific user feedback on long-term durability or performance under sustained heavy loads is available yet due to its future release date.
- While compact, its 150mm depth is standard for many ATX PSUs, not exceptionally small compared to some SFX-L or shorter ATX units.
Dimension Scores
The 80 PLUS Gold certification with up to 90% efficiency and 1000W output with ATX 3.1 and PCIe 5.1 readiness is above average for current high-end systems.
Equipped with a 135 mm Fluid-dynamic bearing (FDB) fan, it's designed for low-noise operation, with early reports indicating it is whisper quiet.
Features an LLC half-bridge with DC-to-DC converter, active PFC design, and industrial-level protections (OCP/OTP/OPP/SCP/OVP/UVP/SIP/NLO) for reliable output.
Its fully modular design and embossed jacket cables, which are more bending and routing, significantly aid in cable management within a PC case.
Best For
- PC builders planning for NVIDIA's 50 series graphics cards and AI PCs.
- Users needing a 1000W power supply with ATX 3.1 and PCIe 5.1 standards.
- Gaming rigs and workstations requiring stable, efficient power for demanding components.
Not Recommended For
- Budget-conscious builds that don't require 1000W or PCIe 5.1 connectivity.
- Small Form Factor (SFF) cases that require SFX or SFX-L power supplies.
Watch Out For
- No widespread user complaints or specific issues have been reported yet, likely due to the product's future release date (June 23, 2025).
- The discrepancy between the advertised 10-year warranty and MSI's website stating 7 years could be a point of confusion for buyers.

What Buyers Say
Since this product is set to be released in June 2025, there isn't extensive real-world user feedback available yet. Early previews and product descriptions highlight its quiet operation and the quality of its cables. The focus is on its readiness for future high-end components, particularly NVIDIA's 50 series GPUs, with its ATX 3.1 and PCIe 5.1 compliance. No widespread complaints have been reported, which is expected given its future availability.
“Man, this thing is supposed to be ready for the new GPUs, and it's super quiet even in the early tests. Cables feel premium, which is a plus for my build.”
Common Praise
- Whisper quiet operation, with only a small clicking sound on startup/shutdown from the fan mechanism.
- Quality of the included cables is surprisingly good.
- Fully modular design makes cable management easier.
- Compact 150mm size helps with case integration and airflow.
Common Complaints
- No widespread user complaints are available yet due to the product's future release date.
- Discrepancy in warranty information between product listing (10 years) and MSI's official page (7 years).
Ownership Tips
- The fan's fluid dynamic bearing should contribute to long-term quiet operation.
- The ATX 3.1 standard and 12V-2x6 connector mean it's built for power excursions of next-gen hardware.
- The compact 150mm depth is a practical benefit for fitting into various ATX cases.

Buying Guide
When you're looking at a power supply, you're essentially buying the heart of your PC. It needs to deliver consistent, clean power to all your components without failing or making too much noise. You need to match its wattage to your system's total power draw, especially your graphics card and CPU, and consider future upgrades. The efficiency rating tells you how much power it wastes as heat, and newer standards like ATX 3.1 and PCIe 5.1 are crucial for the latest high-power GPUs.
Wattage (1000W)
This is the total power your PSU can supply. Think of it like the engine size in a car; a 1000W PSU is like a powerful engine, capable of running high-performance components like top-tier graphics cards and CPUs without breaking a sweat.
80+ Gold
This is an efficiency rating. An 80+ Gold PSU converts at least 87-90% of the power from your wall into usable PC power, wasting less as heat. It's like getting better gas mileage; less energy is wasted, saving you a bit on your electricity bill and keeping your PC cooler.
ATX 3.1 & PCIe 5.1 Ready with Native 12V-2x6
These are the latest industry standards for power delivery. ATX 3.1 means it can handle sudden, large power spikes from components like GPUs, preventing system crashes. PCIe 5.1 with the 12V-2x6 connector is specifically designed for the newest, most power-hungry graphics cards, ensuring they get all the power they need directly and reliably.
Alternatives
If this PSU is overkill, look for an 80+ Gold ATX 3.0 power supply with a lower wattage (e.g., 750W or 850W) if your current or planned GPU doesn't require PCIe 5.1, or a shorter ATX unit if you have a very compact case.
