Monoprice 105278 computer power cord 3.00 ft

Monoprice 105278 3 ft power cord

The Monoprice 105278 is a three-foot black power cable designed to connect a PC power supply or monitor to a standard US three-prong wall outlet. It serves builders and office users who need a short replacement or spare lead for desktop hardware. The two-connector design provides a direct link without excess cable length cluttering the workspace. It has been listed since 2019 as a straightforward mains lead for compatible equipment.

Passive cable thermals and power handling

As a passive mains cable, the unit generates no operational noise and draws no power of its own. It simply conducts the current required by the attached power supply or monitor within the limits of its three-conductor construction. Normal use produces no perceptible heat from the cord itself. There are no active cooling components or electronic circuits to consider.

Sustained load behaviour

Under continuous load the cable behaves as a fixed-conductor link, maintaining conductivity as long as the connected equipment stays within standard household current ratings. No thermal throttling or performance curve applies because the product contains no active components. The three-foot length keeps voltage drop negligible for typical desktop power supplies. It remains a passive conduit regardless of how long the attached system runs.
