EDIT: I really gravedug this Q, didn’t I. Hope you got that amp sorted!
I don’t have an answer to your actual question! However, your desktop may be able to, possibly your laptop, depending on sensitivity also. It’s not that high an impedance. Have you tried it?
If you have a Realtek chip, it may sense them as Ultimate power output. If you’re not getting the gain you want, go into the audio console app and select Ultimate. You may need to plug them into the line out directly, in back, if the front jack isn’t working great. You can then gauge if you have enough power and get an amp if not. Go up to around $100 ($135 shipped with tax, or so) and you can grab a Schiit Heretic or Magni+.
(Also, I’m recently running Beyer DT 900 Pro X with either an oldish Electric Avenues portable op-amp or a Magni+, though it’s overkill. Source DAC. Using raw tuning or reasonably close to Harman via AutoEQ.app and Equalizer APO. Hoping to pick up Audio Technica r70x next year, so I thought I’d prepare to EQ into 450ohms, though I guess they aren’t actually hard to drive.)
