Key takeaways
- 295 listings match this collection right now.
- Four to eight-GPU nodes are the main driver for this wattage class, since each accelerator adds substantial power draw on top of the processors and drives it has to feed.
- The high current an 1600 watt module draws at 120 volts is why the platform requires 200 to 240 volts, an electrical limit rather than a firmware restriction.
- The module dissipates more waste heat at this wattage than lower classes, so the chassis fan curve is tuned to keep the highest wattage option cool along with the GPUs.
1600 watts is the top common class for rack servers, fitted to GPU nodes and dense four-socket systems. Like the 1400 W class, these deliver full output on 200 to 240 V and derate on 110 V.

How to choose power supplies
Server supplies are platform-specific: the part number ties to a chassis family and a wattage class, and a redundant pair must be the same model. Match the wattage class already installed, the input (100 to 240 V AC or 48 V DC) and the efficiency grade if the platform enforces one. Desktop supplies in this category follow ATX form factors instead.
