AZZA offers three power supply models within their Platinum series: 750 W, 850 W, and 1,000 W. Today we are going to take a look at the 750 W version. Let’s check it out.
Power supplies from AZZA are manufactured by Super Flower; the Platinum 750 W is a rebranded Super Flower SF-750P14PE. This power supply is also internally identical to the Kingwin Lazer Platinum 750 W. (The original model from Super Flower and the Kingwin model use connectors on the modular cabling system with LEDs that turn on when the power supply is in operation.)
The AZZA Platinum 750 W is 7.1” (180 mm) deep, using a 140 mm ball-bearing fan on its bottom (Hong Hua HA1425M12B-Z). The unit has a switch on its rear for you to select the mode in which you want the fan to work. In “normal mode,” the fan will increase its speed with the temperature. In “ECO mode,” the fan will be left turned off until the power supply’s internal temperature reaches between 65° C and 70° C, so the power supply won’t emit any noise while it is “cold.”
The modular cabling system from this power supply has six connectors. Differently from most power supplies with a modular cabling system, you can install any kind of cable in any connector, i.e., there is no specific connector for the video card power cables or for the peripheral and SATA power cables. The unit comes with the main motherboard cable, an ATX12V/EPS12V cable, and two video card power cables permanently attached to it. They use 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, 21.6” (55 cm) long, permanently attached to the power supply
- One cable with two ATX12V connectors that together form an EPS12V connector, 24.4” (62 cm) long, permanently attached to the power supply
- Two cables, each with one six/eight-pin connector for video cards, 20.9” (53 cm) long, permanently attached to the power supply
- Two cables, each with one six/eight-pin connector for video cards, 18.9” (48 cm), modular cabling system
- Two cables, each with four SATA power connectors, 19.7” (50 cm) to the first connector, 5.1” (13 cm) between connectors, modular cabling system
- One cable with three standard peripheral power connectors, 19.7” (50 cm) to the first connector, 5.1” (13 cm) between connectors, modular cabling system
- One cable with two standard peripheral power connectors and one floppy disk drive power connector, 19.7” (50 cm) to the first connector, 5.1” (13 cm) between connectors, modular cabling system
The wires for the ATX12V/EPS12V and video card connectors that are permanently attached to the power supply are 16 AWG, i.e., thicker than the minimum recommended. All other wires are 18 AWG.
Even though the number of connectors is satisfactory for a 750 W power supply, we think a high-end unit with the 80 Plus Platinum certification deserves more SATA connectors.
