Ultra LSX 750 Power Supply Review

Introduction

The new LSX series from Ultra so far features only two models, 650 W and 750 W, both with 80 Plus Bronze certification, single +12 V rail, synchronous design with DC-DC modules for the +5 V and +3.3 V outputs in its secondary, and lifetime warranty (if you register the product after buying it).

Models from the Ultra LSX series are manufactured by Andyson.

The Ultra LSX 750 is 6.5” (165 mm) deep, with a 135 mm dual ball bearing fan (Young Lin Tech DFS132512H).

The new Ultra LSX 750 doesn’t have a modular cabling system. All cables are protected with nylon sleeves. The power supply comes with the following cables:

  • Main motherboard cable with a 20/24-pin connector, 22” (56 cm) long
  • One cable with one EPS12V connector and one ATX12V connector, 22” (56 cm) long to the EPS12V connector, 5.9” (15 cm) between connectors
  • Two cables with two six/eight-pin connectors for video cards each, 22.4” (57 cm) to the first connector, 5.9” (15 cm) between connectors
  • Two cables with four SATA power connectors each, 18.5” (47 cm) to the first connector, 5.9” (15 cm) between connectors
  • One cable with three standard peripheral power connectors, 18.5” (47 cm) to the first connector, 5.9” (15 cm) between connectors
  • One cable with three standard peripheral power connectors and one floppy disk drive power connector, 18.5” (47 cm) to the first connector, 5.9” (15 cm) between connectors

All wires are 18 AWG, which is the minimum recommended gauge.

Even though this power supply has four power connectors for video cards, allowing you to install two video cards that require two power connectors each without the need of adapters, they are available on two cables. The number of SATA power connectors is very good for a 750 W power supply (eight), even though we’d prefer to see three cables with three connectors on each cable instead of two cables with four connectors on each cable.
