Nexus is a Dutch company and their power supplies can be easily found in the United States and in Europe, of course. Today we are going to take a look at their 630 W RX-6300 power supply, which comes with a modular cabling system, a single-rail design and an ultra low noise fan. Is it a good buy? Let’s see.

Nexus RX-6300 is 6 19/64” (160 mm) deep, using a 135 mm fan on its bottom and featuring active PFC, of course. It has a modular cabling system, but some of the cables are permanently attached to the power supply (these cables have a nylon protection that comes from inside the power supply case). Also, the modular cabling system has eight connectors, but the power supply comes with only five cables. This power supply comes with the following cables:

• Main motherboard cable with a 20/24-pin connector (permanently attached to the power supply).
• One cable with one EPS12V connector that can be transformed in two ATX12V connectors (permanently attached to the power supply).
• One ATX12V cable (permanently attached to the power supply).
• One cable with one six/eight-pin auxiliary power connector for video cards (permanently attached to the power supply).
• One cable with one six-pin auxiliary power connector for video cards (modular cabling system).
• Two cables with three SATA power connectors each (modular cabling system).
• Two cables with three standard peripheral power connectors and one floppy disk drive power connector each (modular cabling system).

The cable configuration from RX-6300 is perfect for a 630 W product.

The cables that are permanently attached to the power supply are 18 1/8” (46 cm) long, and the cables from the modular cabling system are a little bit longer, with 19 ¾” (50 cm) between the power supply and the first connector on the cable. Peripheral connectors have 5 7/8” (15 cm) between them, but SATA connectors have 7 7/8” (20 cm) between them, which is great.

All cables use 18 AWG wires, which is the correct gauge to be used.
