I'm planning a PC build and am considering open-box or refurbished components to save money. Are there certain parts that are generally safe to buy this way, and others that are better purchased new? I'm especially looking at an ASUS ROG STRIX B850-A motherboard, 32GB of DDR5-6000 CL30 memory, a 2TB NVMe SSD, and a roughly 1000W power supply. What should I check before buying, and are there any reliable places or policies I should look for?

My general rule is that used parts should be substantially cheaper than new ones and come with buyer protection or a warranty. Check the return policy, test everything immediately, and inspect open-box items for missing accessories or physical damage. Some refurbished hardware is perfectly reliable, but the quality depends heavily on who inspected and resold it.
Good point about testing right away. I’ll make sure I have the return deadlines noted before ordering anything.
I’d be cautious with used or refurbished SSDs and power supplies. An SSD may already have a significant amount of data written to it, so check its health and remaining endurance. With a PSU, you need confidence in its age, model, condition, and refurbisher quality. A questionable power supply isn’t worth saving a little money on.
Open-box parts can be a good deal across the board, provided there’s a solid return window. I’ve used open-box graphics cards and motherboards for years without trouble. The important thing is to build and test the system soon after everything arrives so you can return anything defective.
RAM is usually one of the safest used purchases since it has few moving parts. Just run a memory test and make sure the seller accepts returns. Motherboards can also be fine, but inspect the CPU socket pins carefully because they’re easy to damage and expensive to replace.

That’s especially important for RAM and SSDs. I’d only buy them if I could return the RAM after a failed memory test or verify the SSD’s health and remaining lifespan.
