Questions about this item

What is the 255 W limit that appears first when the OptiPlex 980 MT power supply runs continuously?

The 255 W rating is the maximum continuous output; sustained loads above that level will trigger the unit's protection circuit.

How much heat and noise does the 340 W peak-rated ATX supply produce during all-day operation?

At typical loads the fan runs at low speed, keeping noise minimal while the 340 W peak headroom prevents thermal throttling during extended use.
