Most people are afraid to buy used parts because there’s no multi-million-dollar company behind the sale to guarantee their money back. But there is one: eBay. eBay is very protective of buyers’ trust, because without it, eBay wouldn’t exist.
My first GTX 1650 went into my brother’s desktop, a refurbished PC that cost €70. I bought the card used on eBay from a seller I’d never heard of, with the same worry everyone has: what if it’s dead and the money’s gone? It’s a fair worry, and eBay has an answer to it. A used GTX 1650 sells for about €79 on eBay right now, the median of 394 sales in the last 30 days, so a PC like my brother’s comes in under €150 for both.
How you get your money back
You buy a part. If it never arrives, or it arrives broken, faulty or not what the listing said, you report it on eBay. This is the eBay Money Back Guarantee, and it covers you even when the listing says “no returns”.
You have 30 days after delivery to report it. The seller then has 3 business days to respond. If they don’t fix it, you can ask eBay to step in, and eBay refunds you itself. You don’t have to win an argument with the seller.
That last part is why I think eBay can be safer than a shop. If a shop sells you a faulty part, you’re arguing with the shop, and they decide. On eBay, if the seller won’t make it right, someone else decides.
Why sellers play fair
Sellers have their own reason to keep you happy: their rating. If you’re a seller, your rating is one of the biggest signs of success. Buyers check it before they buy, so you do everything you can to keep it high. One bad sale costs a seller more than the refund.
Private sellers and business sellers
In the UK and the EU there are two kinds of sellers on eBay, and the law treats them differently.
A business seller has to give you 14 days to change your mind and send the item back, even if it works fine. That’s the EU right of withdrawal, and the UK has the same rule. Business sellers have to say they’re a business in the listing, usually with their company details at the bottom.
A private seller doesn’t have to take anything back because you changed your mind. On eBay.de you’ll often see “Privatverkauf, keine Garantie und Rücknahme” in the description. That line is about changing your mind. If the part is broken or not what was described, eBay’s guarantee still applies, whoever the seller is.
Buying from a private seller is fine. Just don’t buy something you’re unsure about from a private seller expecting to send it back if you change your mind.
Where the protection stops
The guarantee has a few limits, and they matter more for PC parts than for most things.
Pay through eBay’s checkout, every time. If any part of the payment happens outside eBay, you’re not covered. A seller who asks for a bank transfer or offers a discount to “deal directly” is asking you to give up your protection, so walk away.
“For parts or not working” listings only give you 3 days after delivery to report a problem, if the seller doesn’t offer returns. Cheap dead GPUs and motherboards are listed this way, and that’s fine if you know what you’re buying. Test it the day it arrives.
Changing your mind is only covered if the seller offers returns, or if they’re a business seller in the UK or EU.
Don’t open a chargeback with your bank or card for the same order. That can close your eBay case.
Scams worth knowing about
Read the whole title. When the RTX 5090 and 5080 launched in early 2025, there were eBay listings selling only a photo or the empty box at graphics card prices. The title said so, and people still bought them.
The worst stories usually happen off eBay. In December 2025, a buyer in Germany paid €500 by bank transfer for an RTX 5070 on a classifieds site and got a box with a snack bar and a cigarette in it. Through eBay’s checkout, that’s a “not as described” case you’d win. Paid by bank transfer, the money is gone.
If a parcel feels wrong, film yourself opening it. It takes a minute and settles any argument about what was in the box.
Scams go the other way too. An eBay seller got back a returned RTX 5090 with the GPU chip and memory removed from the board. That’s why careful sellers photograph serial numbers and record a test before shipping. When you see a listing like that, it’s a good sign. That seller has thought about returns and is expecting to be held to what they wrote.
If you sell a part yourself one day, do the same. Photograph the serial number and record the part working before it goes in the box. If a buyer sends back something different, that’s your proof.
What to check for each part
Graphics cards
Ask for a short video of the card running a game or a stress test. Mining cards are their own topic, covered in my guide on buying a GPU on eBay.
CPUs
AMD AM4 processors have pins on the chip, and a bent pin can stop it working. Ask for a clear photo of the underside. Intel and AM5 chips are flat, so the pins live on the motherboard instead.
Motherboards
For Intel and AM5 boards, ask for a close photo of the socket. Bent socket pins are the most common damage, and they’re hard to fix. Check that the I/O shield and any Wi-Fi antennas you need are included.
Power supplies
This is the part I’d be most careful with, because a bad one can take other parts with it. Buy a known model, check how old it is, and ask if the original receipt comes with it, since warranty claims usually need one.
RAM
Low risk. Make sure it’s the exact kit you need (DDR4 or DDR5, speed and capacity), and buy matching sticks as one kit.
SSDs and hard drives
Ask for a screenshot from CrystalDiskInfo. It shows the drive’s health, how many hours it has run and how much data it has written.
Before you buy
- Look at how many ratings the seller has, not only the percentage. 100% from four sales tells you less than 99% from three thousand.
- Ask for real photos of the actual part if the listing only has stock images.
- Compare the price with what the part actually sells for. In the last 30 days, 354 RTX 3060s sold on the eBay markets we track. The median was €284, half of them sold between €257 and €308, and the cheapest went for €197. A 3060 listed at €150 is cheaper than every one of them, and that’s worth a question before you pay. You can check the going price for most parts on pcprice.watch.
