Looks like a standard ATX PSU. However, looking at the Dell forums, they're pointing out to make sure you match the specifications on the label of the PSU. The 5v/3.3v combined wattage seems high for a 460W PSU at 142W combined. Other concerns are on higher wattage units, they may be too long to reinstall the crossbar. I'd say pull the power supply and bring it in with you, or bring the system. I'm confident we can find a replacement for you that'll work fine.

The information the Dell forum here should help you as well: https://www.dell.com/community/Desktops-General-Read-Only/8910-PSU-upgradeable-with-aftermarket-PSUs/td-p/5080238

Dell is notorious for having proprietary components in their builds. Power supplies especially! Ask me how I know. I know enough to never buy another Dell computer.
