I'm planning to build a gaming PC and noticed that AliExpress often lists CPUs, memory, and other components at much lower prices than local retailers. Are the deals generally trustworthy, and which parts are relatively safe to buy there? I'd also appreciate advice on spotting unreliable sellers, counterfeit hardware, or products with little or no warranty support.

There can be legitimate bargains, especially on discontinued or older hardware, but treat every listing as a risk assessment rather than assuming the platform guarantees authenticity. Use buyer protection, record the unboxing if possible, and don’t accept substituted, refurbished, or oddly labeled hardware without checking it carefully.
It’s a marketplace, so the seller matters more than the site itself. Check the product-specific reviews, total sales, buyer photos, and how long the store has been operating. Avoid listings with no meaningful feedback, unusually low prices, or vague product descriptions.
The best deals tend to be on older CPUs and sometimes memory. I’ve seen good prices on chips such as the Ryzen 7 5700X3D, but make sure the exact model is genuine and compatible with your motherboard. For newer parts, compare the final price with established retailers after shipping, taxes, and warranty differences.
CPUs can be a reasonable purchase if the seller has a strong history and hundreds of completed sales. They may arrive as tray versions without a cooler, and shipping can take a couple of weeks. I’d be much more cautious with graphics cards, power supplies, and unfamiliar motherboards.
I wouldn’t buy a no-name power supply or motherboard just to save money. A faulty PSU can damage the rest of the system, and warranty support may be difficult. Cases, fans, and other inexpensive parts are often priced similarly elsewhere, so the risk usually isn’t worth it.

Sorting by sales is useful too, but I’d still read the recent reviews instead of relying only on the sales count.
