Pros
- Achieves up to 93.1% efficiency, reducing energy consumption and heat output.
- Features ATX 3.1 and PCIe 5.1 compatibility, including a native 12VHPWR 600W connector for current and future GPUs.
- Provides 1000W continuous power across two 12V rails, handling transient power spikes up to 2000W.
- Includes a temperature-controlled 120mm fan with airflow-optimized blades for quiet operation.
- Fully modular cabling simplifies installation and improves case airflow.
- Backed by a 10-year manufacturer's warranty.
Cons
- Lacks a semi-passive fan mode, meaning the fan always spins, even at very low loads.
- Cables are described by one user as not being as premium as some competitors like Seasonic.
- The 1000W output is overkill for many mid-range PC configurations, potentially leading to lower efficiency at very low loads.
Dimension Scores
The 80 Plus Gold certification with up to 93.1% efficiency and 1000W continuous power with 2000W transient spike handling is top-tier for its class.
The temperature-controlled 120mm be quiet! fan with optimized blades ensures near-silent performance under load, though it lacks a semi-passive mode.
The 10-year warranty and ability to handle 2000W transient power spikes indicate robust component selection and engineering.
Fully modular cabling allows for clean builds and improved airflow by only using necessary cables.
Best For
- High-end gaming PCs with power-hungry GPUs like the RTX 4090.
- Workstation builds requiring stable, continuous power delivery.
- Future-proofing a system against upcoming GPU power demands.
- Noise-conscious users who prioritize low operational sound under load.
Not Recommended For
- Budget PC builds where 1000W is significantly more than needed.
- Small form factor (SFF) cases that might not accommodate a standard ATX PSU.
- Users who prioritize a completely silent fan stop mode at idle.
Watch Out For
- No specific, measurable complaints regarding coil whine, cable stiffness, or component failures were found in user feedback.

Buying Guide
When buying a power supply, you're looking for consistent, clean power delivery to all your PC components. The wattage needs to match or exceed your system's total power draw, especially your GPU and CPU. Efficiency ratings like 80 Plus Gold tell you how much power is wasted as heat, impacting your electricity bill and system temperature. Modular cables are a huge plus for keeping your PC's interior tidy and improving airflow.
Wattage (1000W)
This is the maximum power your PSU can supply. A 1000W unit is for high-end systems with powerful graphics cards and CPUs, ensuring stable operation without power bottlenecks.
80 Plus Gold
This certification means the PSU is at least 87% efficient at 20% load, 90% at 50% load, and 87% at 100% load. Higher efficiency means less wasted electricity, less heat generated, and potentially lower operating costs.
ATX 3.1 & PCIe 5.1
These are the latest standards for power supplies, crucial for compatibility with next-generation graphics cards that use the 12VHPWR connector. This ensures your PSU can handle the power demands and transient spikes of modern GPUs.
Modular
A fully modular PSU means you only plug in the cables you need. This drastically reduces cable clutter inside your PC case, making builds cleaner, improving airflow, and simplifying component upgrades.
Alternatives
If this 1000W unit is too much, look for an 80 Plus Gold or Platinum rated PSU with ATX 3.1 and PCIe 5.1 support in the 750W-850W range. If you need absolute silence at idle, search for PSUs with a semi-passive or fan-stop mode.
