Before you buy a used RTX 3080 12GB
- Power: a 750W+ power supply with 2-3x 8-pin.
- Size: about 285mm 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.
- Mining history: this card was popular with miners. Not a deal-breaker, but ask, and prefer a tested listing with a fair return policy.
- 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.

Used RTX 3080 12GB FAQ
How much is a used RTX 3080 12GB worth?
There are too few used RTX 3080 12GB listings on eBay UK today to give a reliable typical price. We check every day.
What power supply do I need for a RTX 3080 12GB?
NVIDIA recommends at least a 750W power supply for the RTX 3080 12GB, which draws about 350W on its own. It takes 2-3x 8-pin. Factory-overclocked partner cards can draw more, so leave some headroom.
Will a RTX 3080 12GB fit in my case?
The reference RTX 3080 12GB is about 285mm long and 2 slots thick. Many partner cards (ASUS ROG Strix, MSI Suprim, Gigabyte Aorus) are 20-60mm longer, so check your case's maximum GPU length and the exact card model before buying.
Is a used RTX 3080 12GB good for gaming in 2026?
Its performance score is 68/100 on our scale (100 = the fastest card we track), which as a rough guide means high settings at 1440p. It has 12GB of GDDR6X.
Was this card used for mining?
Cards from 2020-2022 were popular with crypto miners. Mining at a steady, undervolted load is not usually what kills a card, but fans and thermal pads wear. Ask the seller how it was used, look for fan noise or high memory temperatures, and prefer a listing that is tested, boxed or still under warranty. We flag listings that mention mining.
