Enermax PRO87+ 500 W Power Supply Review

Hardware Secrets Golden Award

Introduction

The Enermax PRO87+ and MODU87+ are two series of power supplies with 80 Plus Gold certification. The two series are internally identical, and the one difference between them is the use of a modular cabling system on the MODU87+ models. We’ve already reviewed the MODU87+ 700 W power supply, which achieved terrific performance in our tests. Let’s see if the PRO87+ 500 W follows the same steps.

The Enermax PRO87+ 500 W is 6.3” (160 mm) deep, using a 140 mm, twister bearing fan on its bottom, model EA142512W-OAB. This fan keeps spinning for at least 30 seconds after you turn off the power supply, in order to cool down the power supply components and provide a higher life span.

This unit features active PFC, of course.

As explained, it doesn’t come with a modular cabling system. The cables included are the following:

  • Main motherboard cable with a 24-pin connector, 22.8” (58 cm) long
  • One cable with two ATX12V connectors that together form an EPS12V connector, 23.2” (59 cm) long
  • Two cables, each with one six/eight-pin connector for video cards, 18.5” (47 cm) long
  • One cable with four SATA power connectors, 16.9” (43 cm) to the first connector, 5.5” (14 cm) between connectors
  • One cable with two SATA power connectors and two peripheral power connectors, 16.9” (43 cm) to the first connector, 5.5” (14 cm) between connectors
  • One cable with three standard peripheral power connectors and one floppy disk drive power connector, 16.9” (43 cm) to the first connector, 5.5” (14 cm) between connectors

All wires are 18 AWG, except the wires in the main motherboard cable, which are all thicker (16 AWG).

The cable configuration is perfect for a 500 W power supply.
