SKU CH-DMZR-8CZT9

TFX 500W power supply replaces Acer SFF 180W or 250W units and adds 6Pin GPU support for discrete graphics upgrades

  • 500 W single +12 V rail powers discrete GPU upgrades
  • Direct OEM replacement fits Acer SFF TFX chassis without modification
  • 80 PLUS Bronze efficiency with Active PFC handles 100–240 V input
  • Full OVP/UVP/OCP/SCP/OPP protection shields mainboard CPU GPU storage
  • Pre-tested under full load for long-term stable office operation

OEM Replacement for Acer SFF Desktops

This TFX power supply is a direct replacement for original 180W and 250W units used in Acer Veriton slim small form factor desktops. It matches the factory part codes including FSP500-20TGBAA/B and PA-1181-10AC/10AB. The unit is designed for buyers who need to repair a failed stock power supply or upgrade a system to support a discrete graphics card. It is not suitable for standard ATX cases or motherboards requiring a 24-pin main power connector.

Fixed Wiring Harness and Protection Circuits

The compact TFX dimensions match the original chassis exactly, allowing a plug-and-play swap without any case modification. The fixed harness includes a dedicated 6-pin motherboard connector, a 4-pin CPU connector and a PCIe 6+2-pin GPU connector as defined by the original factory specification. Built-in OVP, UVP, OCP, SCP and OPP protection circuits shield the mainboard, CPU, GPU and storage from surge and short-circuit damage. Each unit undergoes a full-load ageing test before shipment for long-term stable office use.

500W Single +12V Rail with 80 PLUS Bronze

The power supply delivers a rated continuous 500W on a single +12V rail with 80 PLUS Bronze efficiency and Active PFC. It accepts a universal 100-240V AC input for stable operation under unstable grid voltage worldwide. The 6-pin motherboard connector limits compatibility to specific Acer SFF platforms; builders needing standard ATX 24-pin or EPS 8-pin connectors cannot use this unit. The fixed cable set also prevents use in chassis requiring modular or longer cable routing.

What are the physical dimensions and mounting requirements for this TFX replacement?

It uses the standard compact TFX form factor identical to the stock PSU, allowing a direct plug-and-play swap inside the Acer SFF chassis without any modification.
