### ⭐⭐⭐⭐⭐ Well Made Replacement PS for Dell Otptilex
*by V***N on September 29, 2025*

Well made Replacement 255W L255AS-00 PS-3261-2DF Power Supply for Dell Optilex. It is been 2.5 years since replaced, and it is keeping the PC running just fine.

### ⭐⭐⭐⭐⭐ Great power supply
*by M***K on October 20, 2025*

Power supply was exactly what I needed for my Dell computer. Fit perfect and easy to install.

### ⭐⭐⭐⭐⭐ Worked on my dead OptiPlex 3020 sff
*by R***E on November 29, 2025*

The power supply seems solid—no overheating, strange smells, or smoke so far. I revived an old Dell Optiplex 3020 with a bad power supply to use as a server, and while I was a bit wary of the no-name brand, it’s been working fine. I’ll update my review if it fails, but I’m hoping it lasts at least a year running 24/7. If it does, and there’s no fire, I’ll be happy.
