450 W ATX power supply for mainstream builds

This myVolts unit delivers 450 W through a standard ATX form factor with a 20/24 pin main connector that fits both 20 pin and 24 pin motherboards. A 115/230 V voltage switch lets it operate on either mains standard. It is aimed at builders assembling or repairing entry-level Intel or AMD systems that need reliable baseline power.

Connectors free up drive bays and CPU power

The bundle includes three SATA connectors, three peripheral connectors and one floppy connector alongside a single 4 pin ATX12V plug for the processor. No PCIe power leads are present, so the unit suits graphics cards that draw all power from the slot. The mixed connector set covers older and current storage devices without needing adapters.

120 mm ball-bearing fan runs at 32 dB maximum

A 120 mm ball-bearing fan handles cooling while an 80 mm internal fan assists airflow inside the 5.9 by 3.9 by 5.5 inch chassis. Efficiency is rated at 70 % minimum at full load and the unit carries TUV, RU and CE safety approvals. MTBF is specified at 100000 hours under ambient conditions. Overvoltage and short-circuit protection cover all outputs.
