LXun 180W TFX Power Supply Alternatives: 6 Similar Picks Compared

How alternatives compare to LXun

BackPlanePro 300W TFX Power Supply

The BackPlanePro 300W TFX unit offers 100W more power than the LXun 180W model. This extra headroom helps if you plan to add components to your Dell Inspiron SFF system. It measures 2.56 by 3.35 by 6.89 inches and weighs 3 pounds. The unit features active PFC for better efficiency at lower loads. You should choose this if you need more wattage for a standard TFX case. It is not ideal if you require the exact form factor dimensions of the LXun. The increased size may not fit all compact chassis. It provides a straightforward upgrade path for users needing more power without changing the case type.

Apevia 300W TFX Power Supply

The Apevia 300W TFX power supply provides double the wattage of the LXun 180W unit. It measures 3.23 by 2.5 by 6.75 inches and weighs 2.1 pounds. The height is slightly lower than the LXun, which may affect fitment in tight spaces. This unit suits users who need extra power for small form factor builds. It is not suitable for silent builds or those prioritizing high efficiency ratings. You should pick this if you require more power than 180W but still need a TFX form factor. The wider input range supports global use. It is a solid choice for general small PC upgrades where silence is not the primary concern.

Thermaltake Smart 600W 80 Plus ATX PSU

The Thermaltake 600W ATX unit is significantly different from the LXun 180W TFX. It uses a standard ATX form factor, measuring 4 by 7 by 8.9 inches. This unit delivers 600W, which is much higher than the 180W LXun. It features active PFC for improved efficiency. You should choose this only if you are building a standard ATX case, not a small form factor system. The LXun fits in Lenovo desktops, while this unit requires a larger case. It is ideal for users needing high power for standard builds. It does not replace the LXun for compact systems. The size difference makes it incompatible with TFX slots.

CableMod C-Series ModFlex Essentials Cable Kit

The CableMod C-Series is not a power supply but a cable kit for Corsair units. It does not replace the LXun 180W TFX power supply. This item is for users who already own Corsair RM, AXi, or HXi PSUs. It upgrades the appearance of existing cables with yellow-red accents. You should not buy this if you need a new power supply for a Lenovo desktop. It is an accessory for aesthetic improvement only. The LXun provides power, while this kit only changes cable looks. It is relevant only if you are modifying an existing Corsair system. It offers no power delivery or compatibility with TFX form factors.

FOSA 350W Fanless Mini ITX DC Power Supply

The FOSA 350W Fanless Mini ITX unit is designed for silent Mini ITX builds. It measures 1.38 by 0.79 by 6.06 inches and weighs 7.88 ounces. It is much smaller and lighter than the LXun 180W TFX. This unit offers 350W of power, which is higher than the LXun. You should choose this for home theater PCs where silence is critical. It lacks a fan, unlike the LXun which likely includes one. The Mini ITX form factor differs from the TFX size. It is ideal for users prioritizing quiet operation over standard TFX compatibility. The compact size fits small cases better than the LXun.

Professional Angle 250W Dell Replacement PSU

The Professional Angle 250W TFX unit provides 70W more power than the LXun 180W model. It measures 3.35 by 2.6 by 6.7 inches and weighs 1.65 pounds. The width is slightly larger than the LXun. This unit is a replacement for specific Dell desktops like Optiplex and Inspiron. You should pick this if you need a TFX unit for a Dell system. It offers basic connectors for office or light home use. The LXun is targeted at Lenovo M-series desktops. This unit is a functional alternative for Dell users needing more power. It is not suitable for Lenovo systems without adapter considerations.
