E-POWER EP-450P5-L1 450 W ATX power supply

E-POWER 450 W ATX12V power supply

The E-POWER EP-450P5-L1 is a non-modular ATX12V unit rated at 450 W. It suits builders assembling basic office or home PCs that do not require high-wattage graphics cards. The single +12 V rail delivers up to 28 A while the +3.3 V and +5 V rails provide 28 A and 45 A respectively. This connector layout supports older motherboards and drives with six peripheral, two SATA and two floppy plugs plus one 4-pin ATX 12 V connector.

Single 80 mm blue-LED fan thermals

One 80 mm rear fan with a blue LED moves air through the chassis in a conventional pull-through pattern. Over-voltage, overload, short-circuit, over-current and over-power protection circuits engage automatically when limits are exceeded. The supply accepts 100–120 V or 200–240 V at 50/60 Hz without a manual switch, simplifying deployment across regions.

Fixed cable set and protection suite

All cables are permanently attached so there are no loose modular plugs to misplace during assembly. The bundle includes six peripheral connectors, two SATA power leads, two floppy connectors and the 4-pin ATX 12 V lead required by many legacy boards. Every rail is guarded by the full complement of OVP, OLP, SCP, OCP and OPP circuitry built into the platform.
