Hardware Secrets Golden Award

Introduction

The Seasonic S12II Bronze power supply series is comprised of 380 W, 430 W, 520 W, and 620 W models, all with the 80 Plus Bronze certification. Let’s see if the 430 W model is a good pick.

The Seasonic S12II Bronze 430 W is 5.5” (140 mm) deep, using a 120 mm ball-bearing fan on its bottom (ADDA AD1212MB-A70GL).

The reviewed power supply doesn’t have a modular cabling system. All cables are protected with 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, 21.3” (54 cm) long
  • One cable with one ATX12V connector, 21.2” (54 cm) long
  • One cable with one EPS12V connector, 21.2” (54 cm) long
  • One cable with one six-pin connector for video cards, 22” (56 cm) long
  • One cable with one six/eight-pin connector for video cards, 22” (56 cm) long
  • Two cables, each with three SATA power connectors, 16.5” (42 cm) to the first connector, 3.9” (10 cm) between connectors
  • Two cables, each with three standard peripheral power connectors, 16.5” (42 cm) to the first connector, 3.9” (10 cm) between connectors

All wires are 18 AWG, which is the minimum recommended gauge. The number of connectors is outstanding for a 430 W power supply, allowing you to install a high-end video card that requires two auxiliary power connectors without the need for adapters.
