Introduction
Hardware Secrets Silver Award

Nexus is a Dutch company and their power supplies can be easily found in the United States and in Europe, of course. We’ve already tested their 630 W model (RX-6300) and we were impressed with its performance. Is the 850 W model also a good buy? Let’s see.

This power supply is manufactured by ATNG.

Nexus RX-8500 is 6 ½” (16.5 cm) 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 10 connectors, but the power supply comes with only six 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 ATX12V connector (permanently attached to the power supply).
  • One cable with one EPS12V connector (permanently attached to the power supply).
  • Two cables with one six/eight-pin auxiliary power connector for video cards each (permanently attached to the power supply).
  • Two cables with one six-pin auxiliary power connector for video cards each (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 modular cabling system uses white connectors for the SATA and peripheral power cables and yellow connectors for the video card cables. If you install all cables you will still have two empty white connectors and two empty yellow connectors. This power supply supports three-way SLI, but in order to install the third video card you will need to buy the two video card connectors that are missing.

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, with the main motherboard cable using thicker 16 AWG wires, which is terrific.

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