The ZT Series is the latest power supply series from OCZ, with a full modular cabling system – meaning that even the main motherboard cable is detachable – and 80 Plus Bronze certification. Available in 550 W, 650 W, and 750 W versions, let’s see if the 650 W model is a good buy.
ZT Series power supplies are manufactured by Great Wall, while the ZS Series power supplies are manufactured by High Power.
The OCZ ZT Series 650 W is 6.9” (175 mm) deep, using a 140 mm ball bearing fan on its bottom (Yate Loon D14BH-12).
This unit has a modular cabling system with nine connectors: one for the main motherboard cable, one for the ATX12V/EPS12V cable (black), two for video cards (gray), and five for SATA and peripheral power connectors (black). This power supply comes with the following cables:
- Main motherboard cable with a 20/24-pin connector, 21.6” (55 cm) long
- One cable with two ATX12V connectors that together form an EPS12V connector, 23.6” (60 cm) long
- Two cables, each with one six/eight-pin connector for video cards, 22” (56 cm) long
- Three cables, each with three SATA power connectors, 15.7” (40 cm) to the first connector, 5.9” (15 cm) between connectors
- Two cables, each with two standard peripheral power connectors, 15.7” (40 cm) to the first connector, 5.9” (15 cm) between connectors
- One adapter to convert any standard peripheral power connector into a floppy disk drive power connector
All wires are 18 AWG, which is the minimum recommended gauge.
The cable configuration is fair for a 650 W power supply, with two video card power connectors and nine SATA power connectors.
