I'm buying a PC tomorrow and I'm familiar with most component manufacturers, but I'm unsure how much the graphics card's brand matters. The GPU is used, and the seller isn't certain of the manufacturer—possibly PNY—with a sticker that says "SMART."
The price of new graphics cards is too high, so I'm considering this used system. The seller offered a six-month warranty, but only a two-day refund period, and refused to provide a refund receipt for the following week. The person who originally sold the used parts reportedly only used the PC about ten times, which sounds questionable to me.
I plan to inspect and test the system at the store before paying, possibly using HWiNFO. What differences should I expect between brands such as ASUS, MSI, Zotac, and PNY? What should I check on a used GPU, and how risky is it if everything appears to work when I test it?

Before paying, verify the exact GPU model with software such as HWiNFO or GPU-Z rather than relying on a sticker or the seller’s description. Run a demanding game or benchmark while watching temperatures, clock speeds, fan behavior, artifacts, crashes, and unusual noise. Check the ports, fans, heatsink, screws, and power connectors, and confirm that the card is recognized correctly and performs close to results for that model.
The combination of an uncertain GPU identity, a price that seems unusually good, and limited refund protection makes this a risky purchase. Even if it passes a short test, that does not guarantee it will last for months. I would only consider it if the exact card can be identified, the price leaves room for the risk, and the store provides clear written warranty coverage; otherwise, I’d pass.
A physical store is better than buying from an unknown individual, but a verbal six-month warranty is only useful if the store will actually honor it. Ask for the warranty terms in writing, including what failures are covered and what happens if the GPU stops working. A very short refund period is a warning sign if you cannot fully test the system before purchase.
The manufacturer usually makes a smaller difference than the actual GPU model. Brand differences are mostly the cooler, fan noise, factory overclock, build quality, warranty coverage, and power connectors. PNY is a legitimate manufacturer, although its specific card design still needs to be checked. Look up the exact model if possible and make sure it has adequate cooling and the correct power connectors.
If the card really was only used around ten times, would that make it substantially safer to buy? I’m still planning to test it before paying.

Also check whether the card has been heavily modified or repasted. A card can work during a quick test and still develop problems later, so the written warranty matters more than a claim that it was barely used.
