Ultra has recently launched a new power supply series, X4, with seven models featuring a complete modular cabling system and single-rail design. We’ve already reviewed the 850 W model from this series and now we are going to dissect their 500 W version.

Power supplies from X4 series are manufactured by Andyson.

Ultra X4 500 W is 6 19/64” (16 cm) deep, using a 135-mm fan on its bottom and featuring active PFC, of course.

As mentioned, Ultra X4 has a fully modular cabling system, meaning that even the main motherboard cable is removable. The cables included are:

• Main motherboard cable with a 24-pin connector (no 20-pin support) (23” or 59 cm).
• One EPS12V cable (23” or 59 cm).
• One ATX12V cable (23 5/8” or 60 cm).
• One cable with one six-pin video card auxiliary power connector (23 5/8” or 60 cm).
• One cable with one six/eight-pin video card auxiliary power connector (23 5/8” or 60 cm).
• Three SATA power cables with three SATA power connectors each (17 3/4” or 45 cm between the power supply and the first connector, 6 1/8” or 15.5 cm between connectors).
• One peripheral power cable with three standard peripheral power plugs (17 3/8” or 44 cm between the power supply and the first connector, 6” or 15 cm between connectors).
• One peripheral power cable with two standard peripheral power plugs (17 3/8” or 44 cm between the power supply and the first connector, 6” or 15 cm between connectors).
• Two peripheral power cables with two standard peripheral power plugs and one floppy disk drive power connector (17 3/8” or 44 cm between the power supply and the first connector, 6” or 15 cm between connectors).
• One adaptor to convert any peripheral power plug into two fan power connectors.

All wires are 18 AWG, which is the correct gauge to be used, except the wires on the main motherboard cable, which are thicker (16 AWG).

The number of cables and connectors is perfect for a 500 W product.
