AcBel 255W 80 Plus Silver PSU

This power supply delivers 255 watts of continuous output and carries 80 Plus Silver certification for efficient AC-to-DC conversion. It is designed as a direct replacement for Dell Optiplex 360 and 380 series desktop systems. The unit accepts a universal 100-240V input at 50-60Hz, drawing up to 4.0 amps.

Fixed cable set with ATX and SATA connectors

The supply ships with a non-modular loom that includes one 24-pin ATX motherboard connector, one 4-pin ATX auxiliary power connector, two SATA power connectors, one 4-pin Molex connector and one floppy power connector. This fixed wiring covers the original Optiplex motherboard, two SATA drives and a legacy peripheral without adapters. Builders working in other chassis must verify that the cable lengths and connector mix suit their layout.

255-watt ceiling limits modern upgrades

The 255W maximum output restricts the system to low-power CPUs and integrated or entry-level discrete graphics. Adding a higher-wattage graphics card or multiple storage devices will exceed the unit's capacity and can cause instability. The 80 Plus Silver rating confirms efficient operation within this envelope, but the fixed connector count and total wattage make the supply unsuitable for builds that need more power or additional SATA leads.
