Before you buy a used RTX 4080 Super
- Power: a 750W+ power supply with 12VHPWR (16-pin). Push the 16-pin plug fully home and avoid tight bends near the socket: badly seated plugs are the known cause of melted connectors.
- Size: about 304mm long for the reference card; check the exact partner model against your case.
- Proof it works: ask for a photo of the card running a benchmark (3DMark, FurMark or a game's FPS counter) with your eBay name on a note.
- Temperatures: ask for GPU and hotspot temperatures under load and the memory junction temperature (GDDR6X runs hot; over 100°C means tired thermal pads).
- Fans and coil whine: listen for rattling or grinding fans. Fans are cheap to replace; a dead GPU isn't.
- Warranty: some makers transfer warranty to a second owner with the receipt. Listings that mention warranty are flagged above.
- Pay safely: buy through eBay checkout (eBay Money Back Guarantee covers "not as described"), never by bank transfer.

How much is a used RTX 4080 Super worth?

NVIDIA recommends at least a 750W power supply for the RTX 4080 Super, which draws about 320W on its own. It takes 12VHPWR (16-pin). Factory-overclocked partner cards can draw more, so leave some headroom.
