Commander 650 W is power supply from In Win that comes with an army-inspired looks, coming with a 14-mm fan, a modular cabling system and active PFC. Is this a good product? Can it really deliver its labeled power?

This power supply is relatively small, being 6 19/64” (160 mm) deep, featuring a 140 mm fan on its bottom and active PFC circuit, allowing In Win to market this product in Europe. According to the manufacturer this unit has at least 80% efficiency.

As mentioned Commander 650 W comes with a modular cabling system, which can be seen on the pictures below.

Only the main motherboard cable comes from inside the power supply and is protected by a nylon sleeving that also comes from inside the unit. This cable uses a 20/24-pin connector.

All other cables are available on the modular cabling system, and the product comes with seven cables: one EPS12V/ATX12V cable, two 6/8-pin video card auxiliary power cables, two SATA power cables with three SATA power connectors each, one peripheral power cable with four standard peripheral power plugs and one peripheral power cable with three standard peripheral power plugs and one floppy disk drive power plug.

The number of plugs is satisfactory for a mainstream PC, however since it comes with only two auxiliary power cables for video cards you will need to use adapters to convert peripheral power plugs into video card power plugs if you want to install two very high-end video cards in SLI or CrossFire modes, since this kind of card requires two auxiliary power cables each.

All wires are 18 AWG, which is the correct gauge to be used nowadays.

Even though In Win paid to have its own UL number, this power supply is really manufactured by CWT, which is the same manufacturer behind some power supplies from very well-known brands, especially Corsair and Thermaltake (notice that not all units from Corsair and Thermaltake are manufactured by CWT). In this review we were curious to see if this model from In Win used the same project as other CWT power supplies we’ve already reviewed (CWT-750VH, Corsair TX750W and Thermaltake Toughpower 750 W).

This unit is, in fact, a renamed CWT-650VH power supply.

Now let’s take an in-depth look inside this power supply.
