In Win Commander II 850 W Power Supply Review

Introduction
Hardware Secrets Silver Award

The new Commander II series is comprised of 750 W, 850 W, and 1,200 W models, all with 80 Plus Bronze certification and a high-end design with synchronous rectification and DC-DC conversion. In fact, the 850 W model (and only this model) is officially an 80 Plus Silver unit, but In Win decided to downgrade it to 80 Plus Bronze. Let’s see if this new power supply gets our recommendation.

The original Commander series was manufactured by CWT, but the Commander II power supplies are manufactured by Andyson. In fact, the Commander II 850 W is a rebranded Andyson AD-K850AE-D6 and is also sold as Raidmax RX-850AE.

In Win has two different websites (http://www.in-win.com.tw and http://www.inwin-style.com), and this new power supply series can’t be found on either of them. We are always amazed by how many Taiwanese companies have more than one website when they shouldn’t, and don’t have any information when they should.

The In Win Commander II 850 W is 6.5” (165 mm) deep, using a 135 mm ball bearing fan on its bottom (Young Lin DFB132512H, maximum of 1,700 rpm, 91.16 CFM, 36.28 dBA).

This unit has a modular cabling system with six connectors (two for video card power cables and four for SATA and peripheral power cables), and four cables are permanently attached to the power supply. This power supply comes with the following cables:

  • Main motherboard cable with a 20/24-pin connector, 21.6” (55 cm) long, permanently attached to the power supply
  • One cable with two ATX12V connectors that together form an EPS12V connector, 24.4” (62 cm) long, permanently attached to the power supply
  • One cable with one EPS12V connector, 24.4” (62 cm) long, permanently attached to the power supply
  • One cable with two six/eight-pin connectors for video cards, 23.6” (60 cm) long, permanently attached to the power supply
  • Two cables, each with two six/eight-pin connectors for video cards, 19.7” (50 cm) long, modular cabling system
  • Two cables, each with four SATA power connectors, 19.7” (50 cm) to the first connector, 5.9” (15 cm) between connectors, modular cabling system
  • Two cables, each with four standard peripheral power connectors and one floppy disk drive power connector, 19.7” (50 cm) to the first connector, 5.9” (15 cm) between connectors, modular cabling system

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

The cable configuration is excellent for an 850 W product, allowing you to install up to three video cards that require two power connectors each without the need of adapters. However, we’ve seen a few competing products with more SATA power connectors.
