Zorluk: OrtaMotherboards Form Factors and Connectors

A system builder is installing a Mini-ITX motherboard inside a standard ATX mid-tower chassis. Which of the following statements correctly describe the mounting and power connector compatibility considerations for this installation? (Select TWO.)

  1. The Mini-ITX motherboard mounting holes align directly with four standard ATX chassis standoff locations.Cevap
  2. The motherboard can be powered directly using a standard 24-pin ATX main power supply connector.Cevap
  3. C
    Mini-ITX motherboards require a specialized riser adapter to align the rear ports with a standard ATX I/O cutout.
  4. D
    Mini-ITX motherboards require proprietary 14-pin low-power adapters to connect to standard desktop power supplies.

Cevap

The correct statements are that Mini-ITX motherboard mounting holes align directly with four standard ATX chassis standoff locations, and the motherboard can be powered directly using a standard 24-pin ATX main power supply connector.
Mini-ITX motherboards are engineered to be backward compatible with standard ATX computer cases. They share the same rear I/O shield dimensions and align with four of the standard ATX mounting standoffs. Additionally, Mini-ITX motherboards utilize standard 24-pin ATX power supply connectors.

Adım Adım Çözüm

1
Evaluate chassis mounting compatibility for Mini-ITX in an ATX enclosure.
Identify that Mini-ITX (170 mm×170 mm170 \text{ mm} \times 170 \text{ mm}) shares four standardized standoff hole placements with the full ATX form factor specification.
Backward compatibility ensures smaller form factor boards can be mounted in larger compatible cases without custom brackets.
2
Evaluate power connector specification requirements.
Confirm that standard Mini-ITX system boards use standard 24-pin ATX main power connectors.
Standard desktop ATX power supply units (PSUs) supply standard voltages (+3.3V, +5V, +12V) through standard 24-pin P1 connectors across ATX, Micro-ATX, and Mini-ITX motherboards.
