ASUS is the number on motherboard manufacturer in the world and they’ve been expanding to other business for several years, recently reaching the power supply market. Though ASUS power supplies are not sold in the US, this didn’t prevent us from getting our hands on their 750 W product, which is sold throughout the world. Like the 500 W (P-50GA) and 650 W (U-65GA), models that we’ve already reviewed, this unit is manufactured by Delta Electronics. Does this power supply carry ASUS high-quality standards? Let’s see.

Figure 2: ASUS U-75HA 750 W power supply.

ASUS U-75HA is longer than the 650 W version, being 7 1/8” (180 mm) deep, having a 140 mm fan on its bottom (the 650 W comes with a 120 mm model, explaining why the 750 W model is externally bigger), active PFC and no modular cabling system.

All cables have a nylon protection, but sleevings don’t come from inside the power supply, as you can see in Figure 2. The cables included on U-75HA are:

  • Main motherboard cable with a 24-pin connector (no 20-pin option).
  • One EPS12V cable.
  • One ATX12V cable.
  • Two cables with two six/eight-pin auxiliary power connectors for video cards each.
  • Two SATA power cables with three plugs each.
  • Two peripheral power cables with three standard peripheral power plugs and one floppy disk drive power connector each.

The main difference between the 750 W and the 650 W models here is the presence of one additional cable with two six/eight-pin connectors for video cards on the 750 W version.

The cables have 19 ¾” (50 cm) between the power supply housing and the first connector on the cable and 5 ¾” (14.5 cm) between connectors, on cables with more than one connector.

All wires are 18 AWG. Interesting enough the 650 W model uses thicker 16 AWG wires on the +3.3 V outputs from the main motherboard cable, feature not duplicated on the 750 W model.

The number of connectors available is enough for you to build a mainstream PC or even a high-end system with two high-end video cards, but we’d prefer to see each video card power connector installed on an individual cable instead of sharing the same cable.

Now let’s take an in-depth look inside this power supply.
