The new GreenMe power supply series from In Win has 550 W, 650 W, and 750 W versions, all with the 80 Plus Bronze certification. In a very different move, In Win committed to donate USD 1.00 to the World Wildlife Foundation (WWF) for every GreenMe unit sold. We’ve already reviewed the 750 W version; let’s now see if the 650 W model is a good buy.

The In Win GreenMe 650 W is 5.5” (140 mm) deep, using a 120 mm ball bearing fan on its bottom (ADDA AD1212LB-A70GL).

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, 19.7” (50 cm) long
• One cable with two ATX12V connectors that together form an EPS12V connector, 19.7” (50 cm) long
• Two cables, each with one six/eight-pin connector for video cards, 19.7” (50 cm) long
• Two cables, each with three SATA power connectors, 19.7” (50 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, 18.9” (48 cm) to the first connector, 5.9” (15 cm) between connectors

All wires are 18 AWG, which is the minimum recommended gauge. This is the exact same configuration used with the 750 W model, and it is adequate for a 650 W power supply.
