The new “B” series from LEPA carries the 80 Plus Bronze certification and is available in 450 W, 550 W, 650 W, 700 W, 750 W, 800 W, and 850 W versions. Let’s take an in-depth look at the 650 W version, which costs only USD 80.
LEPA is a brand that belongs to Enermax’s distributor, Ecomaster. The manufacturer behind the “B” series is CWT, utilizing the same platform used in the Enermax NAXN 80+, the Enermax NAXN 82+, and the Corsair CX series. (Even though Enermax has its own factories, some of its power supplies are manufactured by others.)
The LEPA B650 is 5.5” (140 mm) deep, using a 120 mm sleeve bearing fan on its bottom (Yate Loon D12SH-12).
The reviewed power supply doesn’t have a modular cabling system. All cables 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, 20.5” (52 cm) long
- One cable with two ATX12V connectors that together form an EPS12V connector, 24.4” (62 cm) long
- Two cables, each with one six/eight-pin connector for video cards, 20.1” (51 cm) long
- One cable with four SATA power connectors, 18.1” (46 cm) to the first connector, 5.9” (15 cm) between connectors
- One cable with three SATA power connectors and one standard peripheral power connector, 18.1” (46 cm) to the first connector, 5.9” (15 cm) between connectors
- One cable with three standard peripheral power connectors and one floppy disk drive power connector, 18.1” (46 cm) to the first connector, 5.9” (15 cm) between connectors
All wires are 18 AWG, which is the minimum recommended gauge. The number of connectors is adequate for a 650 W power supply.
