What Buyers Say
Users frequently highlight the PSU's exceptional efficiency, often noting its Cybenetics Titanium rating despite being advertised as Platinum. The inclusion of two native 12V-2x6 connectors for next-gen GPUs is a recurring point of appreciation. While the unit itself is praised for its quiet operation, some feedback points to the quality of the included cables as a minor letdown, specifically their stiffness and lack of individual sleeving.
“This thing is a beast, powers my 5090 like it's nothing, but seriously, those cables are stiff and a pain to route, come on NZXT!”
Common Praise
- Achieves Cybenetics Titanium efficiency, often exceeding its 80 Plus Platinum rating.
- Includes two native 12V-2x6 PCIe 5.1 connectors for high-power GPUs.
- Operates silently due to the magnetic levitation fan and Zero Fan Mode, especially under 900W loads.
- Built with 100% Japanese capacitors for reliability.
- Handles transient power spikes up to 3000W.
Common Complaints
- The stock 12VHPWR cable is very difficult to plug in.
- Cables are not individually sleeved, feeling less premium for the price.
- Accessory package is spartan, lacking extra frills.
- No option to purchase sleeved cables directly from NZXT.
Ownership Tips
- The Zero Fan Mode keeps the fan off until loads exceed 900 watts, making it truly silent for most daily use.
- The 12V-2x6 cables are quite stiff, requiring careful routing in smaller cases.
- The unit runs cool even under heavy loads, contributing to overall system stability.
- The 180mm length is compact for a 1500W unit, but still needs consideration for case compatibility.

Buying Guide
When buying a power supply, you're looking for stable, clean power delivery to your expensive components. Wattage needs to match your system's total draw, especially your GPU. Efficiency ratings like 80 Plus Platinum or Cybenetics Titanium tell you how much power is wasted as heat, affecting your electricity bill and system temperature. ATX 3.1 and PCIe 5.1 compliance are crucial for modern, high-power graphics cards to ensure proper and safe power delivery.
Wattage (1500W)
This is like the engine size of a car; 1500 watts means it can handle very powerful components, especially the latest high-end GPUs and CPUs, without struggling.
80 Plus Platinum / Cybenetics Titanium
These are efficiency ratings. Platinum means it converts at least 92% of wall power into usable PC power at 50% load, and Titanium is even higher at 94%. More efficient means less wasted energy as heat and lower electricity bills.
ATX 3.1 and PCIe 5.1 compliance with Dual 12V-2x6 Connectors
This is the latest standard for power supplies, specifically designed for new, power-hungry graphics cards. The 12V-2x6 connectors are direct, high-capacity cables that prevent issues seen with older adapter cables on powerful GPUs.
Fully Modular
This means you only plug in the cables you need, making your PC build much cleaner and improving airflow inside your case, like having a tidy garage where everything has its place.
Alternatives
If you don't need 1500 watts or dual 12V-2x6 connectors, search for ATX 3.0/3.1 power supplies with 80 Plus Gold or Platinum ratings and a single 12V-2x6 connector at a lower wattage (e.g., 850W or 1000W).
