This custom-made, 3D-printed power supply unit is presented in Grade A++ (Mint) condition, having never been used and remaining in fully working order. Compliant with ATX standards and measuring 6" x 3.5" x 5.5", the unit delivers a maximum total output of 600W with switchable AC input (115V/230V at 50/60 Hz). It ensures compatibility with Intel Pentium 1 through 4 and AMD processors. The design features a dual-fan cooling system for low noise and ripple, alongside high efficiency and comprehensive safety protections including over-current, over-power, and short-circuit safeguards. Every unit undergoes a 100% full-load burn-in test. Connectivity options include one 16-inch 20+4-pin ATX connector, one 16-inch 4-pin 12V connector, one 16-inch 6-pin PCI-Express (SLI) connector, three large Molex 4-pin connectors, and three SATA power connectors.
