The EarthWatts Platinum is the latest power supply series from Antec, and will be available in 450 W, 550 W, and 650 W versions, coming with the 80 Plus Platinum certification. This new series will reach the North American market next month; we were able to get a sample before its official release. Let’s see if the 650 W model is a good option.

The EarthWatts Platinum is manufactured by FSP.

The Antec EarthWatts Platinum 650 W is 5.5” (140 mm) deep, using a 120 mm ball bearing fan on its bottom (Yate Loon D12BH-12).

This unit doesn’t have a modular cabling system, and all cables use nylon sleeves that come from inside the unit. This power supply comes with the following cables:

• Main motherboard cable with a 24-pin connector, 20.5” (52 cm) long
• One cable with two ATX12V connectors that together form an EPS12V connector, 23.6” (60 cm) long
• One cable with two six/eight-pin connectors for video cards, 21.3” (54 cm) to the first connector, 5.9” (15 cm) between connectors
• One cable with three SATA power connectors, 21.3” (54 cm) to the first connector, 5.9” (15 cm) between connectors
• One cable with three SATA power connectors and one standard peripheral power connector, 21.3” (54 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, 21.3” (54 cm) to the first connector, 5.9” (15 cm) between connectors

All wires are 18 AWG wires, which is the minimum recommended gauge.

The cable configuration is fair for a 650 W power supply, with long SATA and peripheral power cables.
