Who it fits

Key specs explained for this PSU

Wattage: 500W

This power supply delivers a maximum of 500 watts of DC output. This capacity is sufficient for standard office desktops and light multimedia tasks. You should verify that your Dell Optiplex or Vostro model does not exceed this limit. Higher wattage is only necessary if you add dedicated graphics cards or many storage drives. For basic business use, 500W provides stable power without unnecessary excess.

Input: 100-240V~/7A

The unit accepts a wide range of AC input voltages from 100 to 240 volts. This feature allows you to use the power supply in different regions with varying electrical standards. You do not need a voltage converter when traveling or using it in countries with different grid frequencies. The 7A rating indicates the current draw at the lowest input voltage. This flexibility ensures reliable operation regardless of your local power source.

Dimensions: 8.6 x 3.14 x 2.4 inches

These physical measurements define the footprint of the power supply inside your computer case. The length of 8.6 inches must fit within the chassis of your specific Dell model. The width and height are standard for many OEM desktops. You must check your case clearance to ensure the new unit fits without interfering with other components. Accurate dimensions are critical for compatibility with proprietary Dell chassis designs.

Weight: 2.09 pounds

This weight reflects the mass of the internal components and casing. A heavier unit often contains more robust materials and larger heat sinks. You should consider this weight when handling the unit during installation to avoid strain. It also contributes to the overall stability of the power supply once mounted. This mass is typical for a 500W desktop power supply of this form factor.

Warranty: 12-month

The manufacturer provides a twelve-month warranty period for this product. This coverage protects you against defects in materials or workmanship. You can contact the seller via email if issues arise within this timeframe. A one-year warranty is standard for replacement power supplies. It offers peace of mind regarding the reliability of the unit. You should keep your purchase records to validate this coverage if needed.

Physical Design and Build Quality

According to the listing, this unit measures 8.6 inches in length, 3.14 inches in width, and 2.4 inches in height. It weighs 2.09 pounds. These dimensions align with standard form factors for Dell Optiplex and Vostro desktops. You need to verify that your specific chassis, such as the 7080MT or 3060, has the required internal space. The compact footprint allows it to fit into tight office enclosures without requiring major modifications to the case structure. The weight suggests a standard metal chassis, which helps dissipate heat during operation.

The connector layout is specific, featuring an 8Pin, two 6Pin, and two 4Pin configuration. This precise arrangement ensures compatibility with the proprietary power cables found in the supported Dell models. You cannot use this unit with systems requiring different pinouts without custom cabling, which is not recommended. The listing states the unit undergoes high and low voltage testing, aging tests, and load testing before shipment. These procedures aim to ensure stable power output and protect your computer components from electrical faults.

Safety features include short-circuit protection and automatic detection mechanisms. These measures are designed to prevent damage during power surges or internal errors. The listing also mentions a 12-month warranty period. This coverage provides a baseline for reliability, though you should confirm the terms directly with the seller. The build quality appears focused on functional replacement rather than aesthetic enhancement, fitting the needs of users restoring or maintaining existing Dell hardware.

Setup And Daily Use Guide

Installing this power supply requires matching the connector layout to your Dell desktop. The unit features a specific pin configuration of 8Pin, 6Pin, 6Pin, 4Pin, and 4Pin. You must verify that your motherboard and drive cables align with this exact arrangement. The listing confirms compatibility with Dell Optiplex models such as the 7080MT, 7060MT, 3050, 3060, and various Vostro and Inspiron series. It also supports XPS 8940 MT systems. Before powering on, ensure your input voltage matches the 100-240V AC rating. This wide input range allows use in most global regions without manual switching.

Once installed, the unit relies on internal safety mechanisms for stable operation. The manufacturer states each unit undergoes high and low voltage testing, aging tests, and load testing for power, voltage, and current. These processes aim to ensure short-circuit protection and automatic detection features function correctly. In daily use, you can expect consistent power delivery for standard office tasks and light multimedia workloads. The 500W output handles typical component draws without strain. The 12-month warranty provides coverage for defects or unsuitability, allowing you to contact support via email if issues arise. This setup process is straightforward for users familiar with internal PC hardware, provided the connector pins match your existing system requirements exactly.

Before you buy this PSU

When you install this QZLHCHY unit, ensure your Dell Optiplex or Vostro model matches the listed part numbers. The 8Pin, 6Pin, 6Pin, 4Pin, and 4Pin connector layout must align with your motherboard. You should verify that your system components stay within the 500W limit. This power supply fits alongside other Dell replacement options by offering a standardized form factor. You may need to check cable lengths if your chassis is deep. Regular upkeep involves keeping vents clear of dust. This helps maintain the stable power output mentioned in the listing. If your current unit failed, this replacement provides a direct swap. You do not need extra adapters for standard Dell desktops. Just confirm the physical dimensions fit your case. The 12-month warranty offers some peace of mind. Compare this to other listings to see if higher wattage is needed for future upgrades. Stick to the specified input voltage range for safety.

Check before you buy

• Verify your Dell model matches the compatible list.
• Check the 8Pin+6Pin+6Pin+4Pin+4Pin connector layout matches your board.
• Confirm your system power draw stays under 500W.
• Ensure the 8.6-inch length fits your desktop case.
