Kingwin has just released a new power supply series with the 80 Plus Bronze certification and modular cabling, dubbed the Power Force. So far, only an 850 W model was released, also called PF-850. Let’s see how it fared on our tests.
Kingwin power supplies are usually manufactured by Super Flower. The Power Force 850 W, however, is manufactured by High Power and is a rebranded DP-850 BR unit.
The Kingwin Power Force 850 W is 6.3” (160 mm) deep and uses a 135 mm fan on its bottom (Globe Fan RL4ZS1352512HH).
The modular cabling system from this power supply has eight connectors: four red ones for video card cables and four black ones for peripheral and SATA cables. Three cables are permanently attached to the power supply, and they are protected with nylon sleeves that come from inside the unit. This power supply comes with the following cables:
- Main motherboard cable with a 20/24-pin connector, 19.7” (50 cm) long, permanently attached to the power supply
- One cable with two ATX12V connectors that together form an EPS12V connector, 22” (56 cm) long, permanently attached to the power supply
- One cable with one EPS12V connector, 22” (56 cm) long, permanently attached to the power supply
- Four cables, each with one six/eight-pin connector for video cards, 18.5” (47 cm) long, modular cabling system
- Two cables, each with four SATA power connectors, 18.5” (47 cm) to the first connector, 5.9” (15 cm) between connectors, modular cabling system
- Two cables, each with three peripheral power connectors and one floppy disk drive power connector, 18.1” (46 cm) to the first connector, 5.9” (15 cm) between connectors, modular cabling system
All wires are 18 AWG, which is the minimum recommended gauge.
The number of connectors is acceptable for a mainstream 850 W power supply.
