Dimension Scores
The 80 PLUS Titanium certification ensures 94% efficiency at 50% system load, combined with a 1300W output, places it at the top tier for power delivery and energy conservation.
Its 135 mm Fluid Dynamic Bearing fan operates silently, staying off until the system load surpasses 40%, contributing to a very quiet PC under typical use.
Constructed with premium Japanese capacitors and featuring Micro Tolerance Load Regulation (0.5%), this PSU is designed for long-term stability and comes with a 12-year warranty.
The fully modular design allows for complete customization of cable connections, significantly improving internal case aesthetics and airflow.
Best For
- High-end gaming PCs running power-intensive GPUs like the RTX 4090 and high-core-count CPUs.
- Workstations and content creation systems requiring consistent and stable power delivery under heavy loads.
- Users prioritizing maximum power efficiency to reduce electricity consumption and heat output.
- PC builders seeking a long-term, future-proof power supply with a substantial warranty.
Not Recommended For
- Budget-oriented PC builds where a 1300W Titanium-rated PSU is overkill and cost-prohibitive.
- Small Form Factor (SFF) PC cases due to its 170mm length.
- Users who do not require ATX 3.0 or PCIe 5.0 compatibility for current or planned components.
Watch Out For
- The physical length of 170mm means it won't fit in all ATX-compatible cases, especially more compact mid-towers.
- Early versions of the ATX 3.0 standard for this model had 12VHPWR cables that some users reported as mislabeled for 600W instead of 450W, leading to uncertainty about GPU compatibility.
- The premium cost of this 80+ Titanium unit is a significant factor, making it a less economical choice if lower efficiency or wattage PSUs suffice.

Buying Guide
When you're looking at a power supply like this, you're basically buying the heart of your PC. You need to know how much power your components actually draw, especially your graphics card and CPU. Efficiency ratings like 80+ Titanium tell you how much power is wasted as heat, so higher is better for your electricity bill and your PC's internal temperature. Modularity means fewer unused cables cluttering your case, which is a big deal for airflow and aesthetics.
Wattage (1300W)
This is the maximum power your PSU can deliver. For high-end gaming rigs with powerful GPUs and CPUs, you need a higher wattage to ensure stable operation and headroom for power spikes, like a car needing a bigger engine for more horsepower.
80 PLUS Titanium
This is an efficiency rating. Titanium is the highest, meaning 94% of the power drawn from the wall is converted into usable power for your PC at 50% load, like getting more miles per gallon from your car. This saves you money on electricity and reduces heat inside your case.
Full Modular
This means you only plug in the cables you actually need for your components. It's like having custom-length cables for everything, making your PC build much cleaner, improving airflow, and making future upgrades easier.
ATX 3.0 & PCIe 5.0 Ready
This ensures compatibility with the latest generation of graphics cards and motherboards, which can have higher power demands and new connector types (like the 12VHPWR). It's like having the latest charging port for your new phone, ensuring it works seamlessly.
Alternatives
If this 1300W unit is more than you need, look for power supplies with lower wattage (e.g., 850W or 1000W) and potentially a lower 80 PLUS rating like Platinum or Gold to save money, or a shorter physical length if you have a compact case.
