Kingwin Lazer Platinum 850 W Power Supply Review

Hardware Secrets Golden Award

Introduction

Kingwin offers five power supply models within their Lazer Platinum series: 550 W, 650 W, 750 W, 850 W, and 1,000 W. Today we are going to take a look at the 850 W version. Let’s check it out.

The name of Kingwin’s power supply series, “lazer,” is probably a typo, since laser is spelled with “s,” as it is an acronym for Light Amplification by Stimulated Emission of Radiation. Maybe the company thought it was “cool” to spell laser with a “z.” However, “lazer” in Spanish and Portuguese means “leisure,” and they probably didn’t think about that.

Power supplies from Kingwin are manufactured by Super Flower, and the Lazer Platinum 850 W is a renamed Super Flower SF-850P14PE. Internally, this power supply is very similar to the Super Flower SF-850P14XE, which is sold as Kingwin Lazer Gold 850 W, NZXT HALE90-850 M, Sentey Golden Steel Power 850 W, and AZZA Ultima 850 W (PSAZ-850G14). It seems that Super Flower got their Golden Green platform and tweaked it to make it Platinum-level, a.k.a. “Golden King.” Since we’ve already reviewed the NZXT HALE90-850 M and the Sentey Golden Steel Power 850 W, we will be able to see exactly what changes were made.

The Kingwin Lazer Platinum 850 W is 7.1” (180 mm) deep, using a 140 mm fan on its bottom. This fan has a “Kingwin” sticker on it, and we couldn’t find out its real manufacturer. The unit has a switch on its rear for you to select the mode in which you want the fan to work. In “normal mode,” the fan will increase its speed with the temperature. In “ECO mode,” the fan will be left turned off until the power supply internal temperature reaches between 65° C and 70° C, so the power supply won’t emit any noise while it is “cold.”

The modular cabling system from this power supply has six connectors that are transparent and glow when the power supply is on. Differently from most power supplies with a modular cabling system, you can install any kind of cable in any connector, i.e., there is no specific connector for the video card power cables or for the peripheral and SATA power cables. The unit comes with the main motherboard cable, an ATX12V/EPS12V cable, and two video card power cables permanently attached to it. They use nylon sleeves that come from inside the unit. This power supply comes with the following cables:

  • Main motherboard cable with a 20/24-pin connector, 22” (56 cm) long, permanently attached to the power supply
  • One cable with two ATX12V connectors that together form an EPS12V connector, 23.6” (60 cm) long, permanently attached to the power supply
  • Two cables, each with one six/eight-pin connector for video cards, 22” (56 cm) long, permanently attached to the power supply
  • Two cables, each with one six/eight-pin connector for video cards, 19.7” (50 cm), modular cabling system
  • Two cables, each with four SATA power connectors, 20.1” (51 cm) to the first connector, 5.9” (15 cm) between connectors, modular cabling system
  • One cable with three standard peripheral power connectors, 20.1” (51 cm) to the first connector, 5.9” (15 cm) between connectors, modular cabling system
  • One cable with three standard peripheral power connectors and one floppy disk drive power connector, 20.1” (51 cm) to the first connector, 5.9” (15 cm) between connectors, modular cabling system

All wires are 16 AWG, which is thicker than the minimum recommended gauge (18 AWG), except the SATA and peripheral cables, which use standard 18 AWG wires.

We were somewhat unhappy with the cable configuration; we think a high-end 850 W power supply with the 80 Plus Platinum certification deserved more SATA connectors and, although it is not “mandatory,” we would like this unit better if it had two additional cables for video cards, allowing you to install three high-end video cards without the need of adapters.
