Rosewill Performance 650 W Power Supply Review


Performance 650 W (also called RP650-2) is a new power supply from Rosewill, featuring a 120 mm fan, active PFC, two auxiliary cables for video cards and labeled as having a 730 W peak power. Is this a good product? Can it really deliver 650 W? Let’s see.

This power supply is small, being only 5 1/2” (140 mm) deep, featuring a 120 mm ball bearing fan on its bottom that glows blue when turned on and active PFC circuit. It does not feature a modular cabling system. All cables have a nylon sleeving that comes from inside the power supply housing.

The main motherboard cable uses a 20/24-pin connector and this unit comes with two ATX12V connectors that together form an EPS12V connector.

This power supply comes with six peripheral cables: One cable with one 6-pin video card auxiliary power connector, one cable with one 6/8-pin video card auxiliary power connector,  two cables with two SATA power plugs each, one cable with three standard peripheral power plugs and one cable with three standard peripheral power plugs and one floppy disk drive power plug.

We think this power supply could have more SATA power connectors (six, for example), especially because we are talking about a 650 W product.

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

According to Rosewill, this unit is manufactured by a company called ATNG and apparently Rosewill Performance 650 W is a rebadged APL-12CM model. Curiously there is no 650 W model on ATNG’s website.

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