What customers say
The Hydrangea Blue color is a standout feature, offering a refreshing visual centerpiece for custom builds. Users appreciate its strong reliability and quiet operation, confirming its performance. This unit provides exceptional value, delivering high wattage and ATX 3.0 compatibility at a competitive price. It successfully combines high quality power delivery with impressive visual appeal, making it a smart choice for those seeking both function and style.
Know before you buy
ATX 3.1 compliance ensures this power supply is fully optimized for the latest hardware, specifically supporting the high power excursions common in modern GPUs. It includes the native 12V-2x6 connector, which provides a safer and more reliable power delivery for high-end graphics cards without needing bulky adapters.
Yes, the unique Hydrangea Blue finish is designed to stand out. However, because many modern cases feature a power supply shroud, the visibility of the color will depend on your specific case design and whether it has a side cutout or window to showcase the PSU.
The Smart Zero Fan mode keeps the 120mm fluid bearing fan stationary during low-load tasks, such as web browsing or light office work, to ensure silent operation. The fan will only begin spinning once the power supply reaches a specific load threshold, balancing silence with necessary cooling.
Absolutely. Since the unit is fully modular, you only need to plug in the cables your system actually requires, which significantly reduces clutter inside your case. The included flat, low-profile cables are also much easier to route behind the motherboard tray compared to traditional sleeved cables.
While 1050W is substantial, it provides excellent headroom for future upgrades or high-end components that may have sudden power spikes. If you are running a standard mid-range build, this unit will operate efficiently and quietly, though you could likely get away with a lower wattage model if you don't plan on upgrading to power-hungry hardware later.
This unit is equipped with a full suite of industrial-grade protections, including Over Current, Over Voltage, Under Voltage, Over Power, Short Circuit, and Over Temperature protection. These features work together to shut down the unit safely if an electrical fault occurs, protecting your motherboard, GPU, and other expensive components.
