At Gattatron Computers, quality is our top priority.
If a customer receives a faulty product from us, we see that as a failure on our part, and we take that seriously. Every computer we sell goes through a thorough, step-by-step testing and quality control process to ensure it’s running at its absolute best before it leaves our hands.
It all starts before the build even begins. Each component is carefully cleaned and checked. We test the power supply unit (PSU) using a dedicated physical PSU tester to confirm it delivers stable power. The graphics card is disassembled, cleaned inside and out, and repasted with fresh thermal paste to improve cooling and longevity. We also inspect every component for signs of physical damage or wear. If anything doesn’t meet our standards, it’s replaced. No exceptions!
Once the components are ready, the PC is assembled. From there, we enter the BIOS to configure the system properly. We set the RAM to the correct speed and check the Trusted Platform Module (TPM) status. If the TPM isn’t enabled or is missing, we update the BIOS to the latest version to ensure compatibility with Windows 11. With the BIOS configured, we install Windows 11 using a USB drive. Then we proceed to install all system updates, including all optional updates and the latest GPU drivers.
The next phase is stress testing. We use OCCT to run four 30-minute tests, each at 100% load: one each for the CPU, memory, 3D standard (GPU), and VRAM. These tests help us identify any hardware issues or thermal concerns. If a component overheats or fails any part of this process, it’s repaired or replaced immediately.
Following OCCT, we run FurMark for a minimum of 10 minutes, using both the general stress test and the artifact scanner to check for any graphical issues or stability problems. We then test all installed storage drives using CrystalDiskMark and CrystalDiskInfo. Drives showing signs of bad sectors or cautionary health status are removed and replaced. Once storage health is confirmed, we continue with running the PassMark Performance Tests, which host a full suite of benchmarks to measure the system’s performance and stability.
For CPU performance, we use Cinebench R23, running both single-core and multi-core benchmarks for 10 minutes each. The results from this test are included in the computer’s product description. To test overall thermal and system stability under extreme load, we run Cinebench R23 alongside FurMark and closely monitor temperatures and clock speeds.
To test GPU performance and stability, we use Unigine Heaven 4.0. First, we benchmark the system using moderate settings: DirectX 11, medium quality, normal tessellation, and x2 anti-aliasing. After that, we turn everything up to max: ultra quality, extreme tessellation, and x8 anti-aliasing. We run the benchmark through every video output on the GPU, one full cycle per port, to ensure all outputs function properly.
Once all tests are complete, we perform a final round of checks. We confirm that temperatures are within safe ranges, that all fans and cooling solutions are operating correctly, and that every port on the system—from USB to video—is working as expected. Only after passing every stage of our process do we list a computer for sale.
We take pride in our work, and we want you to feel confident that when you buy from Gattatron Computers, you’re getting a system that’s been tested, fine-tuned, and built to last.
We believe in transparency and want to empower our customers with the same knowledge and tools we use ourselves. One of our goals at Gattatron Computers is to make PC gaming more accessible—not just by offering great systems at fair prices, but also by helping everyday users understand how to properly test and maintain their own PCs. That’s why we’re sharing our entire process publicly. The best part? Every piece of software we use in our testing routine is free to download and use. Whether you’re buying a system from us or just want to stress test your own build, you’ll have access to the same high standards we hold ourselves to.
