What Buyers Say
Many users appreciate the fully modular design and the inclusion of dual 12V-2x6 cables for modern GPUs, making cable routing straightforward. The Cybenetics Platinum efficiency and 10-year warranty are frequently highlighted as significant benefits. However, some users have noted that the iCUE software can be buggy, and despite the Zero RPM mode, the fan can become audible under heavy loads. The weight of the unit and the implementation of the 12V-2x6 cables (using 2x8 pin on PSU side) have also been points of discussion.
“Man, this thing is a beast, but seriously, the iCUE software is a pain sometimes, and I swear I can hear the fan kick in when my 5090 really gets going, even with that 'silent' mode.”
Common Praise
- Fully modular cabling system makes clean and organized PC builds easy.
- ATX 3.1 and PCIe 5.1 compliance ensures support for the newest graphics cards and platforms.
- Cybenetics Platinum efficiency reduces power consumption and heat output.
- Zero RPM fan mode provides near-silent operation during low to medium system loads.
- Includes two 12V-2x6 cables with dual-color connectors for visually confirming secure connections.
- The 10-year manufacturer's warranty offers long-term peace of mind.
Common Complaints
- The fan can get noisy under heavy system load, despite the advertised ultra-low noise features.
- CORSAIR's iCUE software is sometimes buggy and not always user-friendly for controlling settings.
- The power supply is heavy, weighing over 5 lbs, which can be an issue for installation in certain cases.
- Some users feel the number of PCIe 8-pin connectors is limited for a 1500W power supply, especially for multi-GPU setups.
- The 12V-2x6 cables connect to 2x8 pin ports on the PSU side, which some users prefer to be a true native 12V-2x6 port.
Ownership Tips
- The dual 12V-2x6 cables are braided and include low profile combs, which helps significantly with cable routing and aesthetics inside the case.
- The PSU's weight, over 5 lbs, is quite noticeable during installation, especially when trying to maneuver it into a case, and might require extra support.
- While the iCUE software offers control, many users find the default fan profile to be sufficient and rarely interact with the software after initial setup.
- The two-tone connectors on the 12V-2x6 cables are a small but helpful detail, providing visual confirmation that the cable is fully seated and secure.

Buying Guide
When picking a power supply, you're looking for stable power delivery to your components. Wattage needs to match your system's demands, especially with power-hungry GPUs. Efficiency ratings like Cybenetics Platinum mean less wasted electricity and less heat. Modularity simplifies cable management, making your build cleaner and improving airflow.
Wattage (1500 watts)
This is the total power the PSU can deliver. Think of it like the horsepower of a car; a higher number means it can handle more demanding components, especially multiple high-end graphics cards or overclocked CPUs, without being overloaded.
ATX 3.1 & PCIe 5.1 Compliant
This means the power supply is built to handle the latest generation of graphics cards and motherboards, specifically designed to manage transient power spikes without system instability. It's like having a modern electrical system in your house that can handle all your new appliances without tripping a breaker.
Cybenetics Platinum Efficiency
This rating indicates how much power the PSU converts into usable electricity versus how much is lost as heat. Platinum means it's converting at least 90% of the power efficiently, which saves on your electricity bill and keeps your system cooler by generating less waste heat.
Alternatives
If you don't need 1500 watts, look for ATX 3.1 certified power supplies with Cybenetics Platinum or Gold efficiency in 1000W or 1200W capacities, especially if you prioritize a true native 12V-2x6 connector on the PSU side.
