Dimension E310 Power Supply

I need to replace the original power supply on an old Dimension E310. The sticker on the existing power supply shows the following info:

Model: H230N-00

P/N: HP-P2307F3 LF

I've read some things about needing an EPS12v power supply. And since it's such an old PC, everything I've looked up refers to power supplies that are no longer available. Newer versions of recommended power supplies have been replaced with higher output power supplies and I'm just concerned about finding the right one with all the right connectors. I don't care if it's a refurb or something new, just that it is compatible. And there's obviously no need to get anything pricey. I can probably go on eBay and find the exact model or part number, which would be easiest for a direct swap, but then it's going to be an ancient power supply. If that's the only way to be certain about compatibility, or if it's significantly cheaper, I'm OK with it, as I don't plan on keeping this too much longer. I'm also trying to avoid messing around with different connectors. I would prefer something that is just plug and play.

Note: There's no board for Dimensions anymore, so I created the thread here. I apologize if that's frowned upon. I didn't know where else to create it.

Thanks for the help.
