Who it fits

Key specs explained for this PSU

Wattage: 480W

This rating indicates the maximum continuous power the unit can deliver to your components. You should ensure your total system draw, including CPU and GPU, stays below this limit. It suits modest builds or office PCs. If you plan to add high-end graphics cards, you likely need a higher wattage unit to maintain stability under load.

24 pin ATX with detachable 4 pin section

The main motherboard connector is a standard 24-pin design. The detachable 4-pin section allows you to remove the extra pins if your motherboard only uses a 20-pin configuration. This flexibility helps you manage cable clutter. It ensures compatibility with both older and newer motherboards without forcing you to use unnecessary cables.

Overvoltage protection

This feature monitors the output voltage and shuts down the power supply if it exceeds safe levels. It protects your expensive components from damage due to electrical spikes. You benefit from this safety net in areas with unstable power grids. It is a standard requirement for modern desktop power supplies to ensure hardware longevity.

Overpower protection

This mechanism cuts power if the total output exceeds the rated 480W limit. It prevents the unit from failing catastrophically during heavy loads. You gain peace of mind knowing the system will stop rather than send excess power to your parts. This is a critical safety feature for any desktop power supply.

Replaces many Dell/HP/Compaq Models

This unit is designed as a direct replacement for older proprietary power supplies from major brands. You can use it to revive older business desktops or workstations. Check the physical dimensions and connector types carefully before purchasing. It is ideal for users upgrading legacy systems who need a reliable, compatible replacement source.

Physical Build and Dimensions

The Logisys PS480D measures 5.9 by 7 by 7 inches. This compact footprint allows it to fit into smaller desktop cases. The unit weighs 2.06 pounds. This light weight suggests a standard steel or aluminum chassis, though the listing does not specify the exact metal grade. You should check your case dimensions before purchase to ensure the 7-inch length does not obstruct drive bays or cable routing.

According to the listing, the power supply features a 20/24-pin ATX main connector with a detachable 4-pin section. It also includes a dedicated 4-pin ATX12V connector for the CPU. This layout supports both older 20-pin motherboards and modern 24-pin standards. The detachable design helps you manage cables in tighter spaces. You can remove the extra pins if your board only uses 20 pins, reducing clutter.

The unit complies with FCC Part 15 Class B for 115Vac operation and CISPR22 for 230Vac operation. This indicates it meets standard electromagnetic interference limits for residential use. You can place this unit in a home office or bedroom without worrying about excessive electrical noise. The finish is not detailed in the provided specifications, so you should assume a standard functional coating. This build style prioritizes compatibility and basic size constraints over premium aesthetics.

Setup And Daily Use Guide

Installing this unit requires connecting the primary 24-pin ATX cable to your motherboard. The connector features a detachable 4-pin section. This design allows you to remove the extra pins if your board only needs a 20-pin connection. You must also attach the separate 4-pin ATX12V connector. This provides additional power to the CPU socket. Ensure both connections are fully seated before powering on the system.

This power supply is designed to replace older units in Dell, HP, and Compaq desktops. If you are upgrading an older office PC, check your motherboard layout first. The compact 5.9 by 7 by 7-inch footprint fits standard cases. However, verify that your case has enough clearance for the length. The 2.06-pound weight is light, so handle it gently during installation.

In daily use, the unit supports 115Vac operation in the US and 230Vac operation in other regions. It includes overvoltage and overpower protection. These features safeguard your components from power spikes or excessive load. The unit complies with FCC Part 15 Class B standards. This ensures it meets regulatory requirements for electromagnetic interference. You can run your system with confidence, knowing the electrical safety protocols are built into the switching design. Just ensure your total component draw stays below the 480W limit for stable performance.

Before You Buy This PSU

You should verify that your motherboard accepts the 24-pin connector with its detachable 4-pin section. Many older boards require a full 20-pin connection, so confirm the physical fit before installing. This unit is designed to replace many Dell, HP, and Compaq models. You must check that your case has the correct mounting holes for this specific form factor. The compact dimensions of 5.9 by 7 by 7 inches fit standard desktop enclosures, but smaller cases may lack space. You should also ensure your system’s total power draw stays safely below the 480W limit. This supply lacks active cooling details in the listing, so you may need to monitor temperatures during heavy loads. It suits modest builds or office PCs better than high-end gaming rigs. Consider this option alongside other 480W units if you need a direct replacement for legacy business hardware. The included overvoltage and overpower protections offer basic safety for your components.

Check before you buy

• Confirm motherboard accepts 24-pin with detachable 4-pin section
• Check case dimensions allow 5.9 by 7 by 7 inch fit
• Verify system power draw stays below 480W limit
• Ensure mounting holes match legacy Dell or HP standards
