I Bought a Modern CPU on AliExpress, Here's How It Went

Buying a CPU from AliExpress: A Risky Gamble That Paid Off (This Time)

I had reservations about purchasing a CPU from AliExpress. While counterfeiting CPUs is difficult, it's not impossible. A seller could send a non-functional imitation, although proving this should be straightforward, and AliExpress should offer a full refund. Another scam involves shipping a genuine but cheaper model, perhaps with a swapped heat spreader (IHS). For example, instead of the AMD Ryzen 7 7700 I ordered, I could have received the much less expensive Ryzen 5 7500F.

Given these risks, why did I buy a relatively pricey CPU from AliExpress? The answer is simple: price. The Ryzen 7 7700 cost me $200 including shipping—significantly less than the ~$300 I'd pay locally. Amazon's current price of $275 wasn't feasible due to my location. The AliExpress listing appeared legitimate, boasting over a thousand purchases and numerous positive reviews with photos, so I took the plunge.

The CPU: Authentic and Functional

After a nerve-wracking three weeks, the CPU arrived in a remarkably flimsy cardboard box, containing a bubble-wrapped CPU. It was a tray CPU (without the original retail packaging), which I expected. However, the packaging's poor quality was surprising, given the CPU's value.

I installed the CPU in my new motherboard, applied thermal paste, secured the cooler, and powered on the PC. To my relief, the system booted immediately, and the motherboard UEFI (BIOS) correctly identified it as a Ryzen 7 7700.

Following a successful Windows 11 installation, Task Manager displayed the expected base and boost clock speeds, along with the correct core and thread counts. AMD Software and CPU-Z further confirmed the processor's authenticity.

Subsequent game and stress tests revealed flawless performance. I later enabled Precision Boost Overdrive (PBO) and set a maximum temperature of 85°C (instead of 95°C) for better longevity. The CPU consistently runs at approximately 5.2 GHz, even with a -30mV undervolt—all excellent results for this chip. It's not only functional but also a high-performing unit.

I've used the CPU daily for about 10 days without problems. While most defective CPUs fail quickly, late failures are possible. Therefore, I'm not entirely out of the woods, and I'm uncertain about warranty coverage from AMD, AliExpress, or the reseller.

Why You Should Probably Avoid AliExpress CPUs

Despite my positive experience, I wouldn't recommend buying CPUs from AliExpress. As a tech writer, I was willing to accept the risk. I used my own funds, knowing the outcome would make a compelling article regardless. The price difference—a saving of roughly $100—justified the risk for me, but this may not apply to everyone.

Many countries impose taxes and customs duties on expensive imports. While I avoided these, reviews from Spain and other European countries show buyers incurring customs fees, pushing the final price to around $300. Americans now face a 10% tariff on goods from China. In such cases, buyers not only waste money and time but also face questionable warranty protection.

Instead of searching for CPUs on AliExpress, I suggest waiting for sales on reputable sites like Amazon and Newegg, or choosing a more affordable option. Previous-generation hardware remains relevant and often goes on sale as retailers clear stock. For the best value, consider a used CPU from a trustworthy seller. Used CPUs are generally reliable and can last for years; I've purchased several without issues.
