1280W ATX switching supply

This 1280W ATX switching power supply delivers high-wattage output for workstations and servers that demand sustained power. It suits system integrators and enthusiasts building multi-GPU rigs or compute nodes where a single robust unit simplifies cabling. The unit is supplied new and test-verified for reliable operation.

Test-verified quality assurance

Each unit undergoes a functional test before shipping, reducing the chance of a dead-on-arrival component in a fresh build.

Questions about this item

Will the 28 A rail need any maintenance or replacement later?

The 28 A rail is a solid-state output with no moving parts, so it does not require scheduled maintenance or periodic replacement under normal operation.

What limit appears first when the supply runs at full 1280 W continuously?

The 28 A current ceiling on the main rail is reached before the 1280 W rating, so sustained loads above that current will trigger protection even if total power is lower.
