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 650 W product, which is sold throughout the world. Like the 500 W (P-50GA) model we already reviewed this unit is manufactured by Delta Electronics. Does this power supply carry ASUS high-quality standards? Let’s see.

U-65GA is 6 1/8” (15.5 cm) deep, having a 120 mm fan on its bottom, active PFC and no modular cabling system.

All cables have a nylon protection, but the sleevings don’t come from inside the power supply, as you can see in Figure 2. The cables included on U-65GA are:

  • Main motherboard cable with a 24-pin connector (no 20-pin option).
  • One EPS12V cable.
  • One ATX12V cable.
  • One cable with two six/eight-pin auxiliary power connectors for video cards.
  • 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.

This model brings two SATA plugs and one floppy disk drive power connector more than the 500 W model from ASUS (P-50GA).

The cables are somewhat short, having 19” (48 cm) between the power supply housing and the first connector on the cable and 5 7/8” (15 cm) between connectors, on cables with more than one connector. The length of the cables may make it difficult for you to use this power supply inside a full tower case or even on a mid-tower case where the power supply is installed on the bottom of the case.

Almost all wires are 18 AWG. The main motherboard cable uses thicker 16 AWG wires on the +3.3 V outputs, which is always nice to see. This is a step up to the 500 W model, which uses thinner 20 AWG wires on the ATX12V/EPS12V cable.

The number of connectors available is enough for you to build a mainstream PC, but the two video card power connectors available are installed on the same cable, which isn’t the best configuration: it is always better to see them using individual cables.

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