Looking Beyond the Logisys 480W Switching Power Supply? 6 Alternatives Worth a Look

How these alternatives compare

Sirlyr White 24-Pin RGB PSU Extension Cable

The Sirlyr White 24-Pin RGB PSU Extension Cable is not a power supply. It is an accessory that adds customizable lighting to your build. The original Logisys unit provides raw power with 480W output and essential protections like overvoltage and overpower safeguards. This Sirlyr cable offers no power generation. It simply extends the connection while adding aesthetic value through full-spectrum RGB effects. You should choose this if your case supports mid-to-full tower dimensions and you prioritize visual customization over raw utility. It fits users who want to enhance the look of their power cables without changing the underlying power delivery system.

EZDIY-FAB 300mm 16AWG PSU Extension Cable Kit

The EZDIY-FAB 300mm 16AWG PSU Extension Cable Kit focuses on aesthetics and cable management rather than power generation. Unlike the Logisys PS480D, which delivers 480W of power, this kit provides white-colored cables to match a cohesive theme. It includes multiple PCIe connectors for high-power builds. The 300mm length requires a case that can accommodate extra cable depth. You should pick this alternative if you are building a white-themed PC and need to route cables cleanly. It does not replace the power supply itself but enhances the visual presentation of your existing unit. It is practical for builders who value a unified look in their mid-to-full tower cases.

The Logisys model is larger and provides 480W. This Apevia unit is designed for compact TFX builds where space is limited. It provides 300W of power, which is less than the Logisys 480W. You should choose this if you are building a small form factor PC and need standard TFX dimensions. It works for users with modest power requirements who prioritize size over higher wattage or modern efficiency ratings. It is a practical choice for tight cases.

Thermaltake Smart 500W 80 Plus White PSU

The Thermaltake Smart 500W 80 Plus White PSU provides 500W of output, which is higher than the Logisys 480W. It features an 80 Plus White efficiency rating and active PFC. The Logisys unit lacks these efficiency certifications. This Thermaltake model measures 4 by 7 by 8.9 inches and weighs 3.8 pounds. It includes a five-year warranty. You should pick this if you need a standard ATX build with slightly higher power and better efficiency. It is a practical choice for users who want reliable power delivery without needing high-end certifications. It fits standard ATX cases where efficiency ratings are not the top priority but are still valued.

Thermaltake Smart 500W 80 Plus White PSU

The second Thermaltake Smart 500W PSU also provides 500W of output, exceeding the Logisys 480W. It has a different physical size, measuring 7.87 by 4.33 by 9.84 inches, and weighs only 6.88 ounces. The Logisys unit is heavier at 2.06 pounds. This model lacks explicit efficiency ratings in its basic description.

It fits standard ATX builds where space and weight are considerations. It is a practical option for those seeking a simple power solution without complex features.

Apevia SFX 400W Power Supply

The Apevia SFX 400W Power Supply uses a compact SFX form factor, differing significantly from the larger Logisys ATX unit. It measures 4 by 2.5 by 5 inches and weighs 2.03 pounds. The Logisys model provides 480W, while this unit offers 400W. It is designed for Mini ITX and Micro ATX builds. You should pick this if you need a small form factor solution that fits tight spaces.
