    • 2 x 4+4 Pin CPU 12V (700mm)
    • 6 x 6+2 Pin PCI-e (650mm + 100mm)
    • 12 x SATA (500mm + 100mm each)
    • 5 x 4-Pin Peripheral (500mm + 100mm each)

The most notable feature here is the fanless mode, and thus the Hybrid name of the unit. Essentially what happens is when the unit is operating at less than 200W load, the fan shuts off and runs silent. However, when a heavier load is applied above 200W or 50°C, the fan kicks in and runs just like a regular power supply.

Let’s take a closer look at the Silent Pro Hybrid 1050W.
