Your system is not a line item. It is a project we take personally.
We are a small, hands-on operation. The people who answer your questions, select your components, build your system, run every test, and pack the box are the same team from start to finish. There is no handoff, no assembly line, no corner to cut that nobody would notice. Every decision is made by someone whose name is on the invoice.
We choose parts the way you would if you had the time.
Every component in a JET.TECH system is selected for a reason. We do not pick the cheapest option that meets a spec sheet. We pick the one we would put in our own machine.
Power Supplies
We select PSUs based on internal componentry, topology, and warranty length, not brand name. The brands you see on the box often contract the same ODMs, and we know which ones build to a higher standard. PSUs are typically the longest-lasting component in a build outside of the case, and they carry the longest defined warranties. An extra $20 today on a properly engineered unit can easily save you $200 a few years from now.
Memory
Every kit is validated at XMP/EXPO speeds before it goes into your build, not just at stock JEDEC. If a kit can not pass our memory testing, it does not ship.
Cooling & Noise
The human ear responds more to changes in noise than to absolute volume. A system that stays at a consistent, low hum is far less obtrusive than one that is mostly silent but ramps aggressively when the load spikes. We tune fan curves for tonal consistency first, then bring that consistent level as low as possible while maintaining safe temperatures. We also check for harmonic resonance between fans and coil whine. These are problems you would only discover after living with the system.
Storage
NVMe drives are benchmarked individually with CrystalDiskMark. We confirm advertised sequential and random I/O speeds are met before the drive goes into production.
Cases
We choose cases based on build quality, material use, and overall airflow first. From there, we look for enough clearance for longer GPUs, room for additional storage, accessible cable management, and cooling capacity that scales with higher-wattage components. A good case should outlast multiple hardware generations without becoming the bottleneck.
Motherboards
Board selection starts with VRM quality, then the individual featureset the build actually needs. We also check specifics that most builders skip, like which WiFi and Bluetooth controllers are built in. Some integrated wireless cards are notoriously worse than others, and a cheap WiFi chip can quietly undermine an otherwise excellent system.
Built to Upgrade, Not Replace
Because your case, PSU, and cooler were chosen with headroom from the start, upgrading your system means swapping core components, not buying an entirely new machine. A CPU and GPU upgrade into an existing JET.TECH build can save you over a thousand dollars compared to starting from scratch. We will also help improve competitor builds that are almost what you want but are not quite there. The goal is getting you the best system possible, not selling you the most parts.
Every system is validated before it leaves the bench.
We do not run a single benchmark and call it done. Each subsystem is tested individually with tools chosen to expose different categories of failure. A system that passes one stress test can still fail under another, which is why we run several.
24 Passes of Memtest86
12 passes on our test bench to validate the kit itself, at both stock JEDEC and full XMP/EXPO speeds. Then 12 more passes in the completed system at XMP/EXPO, generating comparative data against the test bench results. This validates not just the RAM but the motherboard's memory traces, slot integrity, and signal quality under the specific electrical characteristics of the final build.
Performance, Stability, Thermals
Cinebench confirms expected multi-core performance. OCCT stress-tests stability under sustained mixed loads. Prime95 pushes thermal limits to validate cooling under worst-case conditions. This combination exposes quirks like throttling, voltage instability, and cooler mounting issues that no single tool would catch alone.
Benchmarks & Burn-In
3DMark provides a standardized performance baseline. FurMark runs a thermal stress test at maximum power draw. GPU-accelerated Cinebench validates compute workloads. When a customer has a specific use case, we also test with their actual applications or games when possible.
I/O Validation
Every NVMe and SSD is benchmarked to confirm advertised sequential and random read/write speeds. HWiNFO64 monitors drive health, temperatures, and SMART data throughout testing to flag early signs of failure before the system ships.
Noise & Acoustics
Fan profiles checked at idle and under load. We listen for harmonic resonance between fans, coil whine from the GPU or PSU, and vibration-induced buzz. A system that looks silent on a spec sheet can still be annoying to live with. We catch that before you hear it.
System Telemetry
HWiNFO64 runs throughout every test, logging temperatures, voltages, fan speeds, and clock rates. This confirms that nothing is throttling, overheating, or underperforming under real sustained loads, not just a 30-second burst.
Custom Loop Validation
Every custom loop is tested for leaks under pressure and monitored for coolant temperatures under sustained load. Beyond individual builds, we maintain long-running coolant tests spanning 3+ years of continuous operation to validate quality and longevity across multiple formulations. We also test pumps and components that other builders avoid, generating our own statistical evidence rather than relying on assumptions or secondhand reputation.
Custom Cable Testing
Every custom cable is tested for correct voltage delivery, voltage droop under load, and plug insertion ease. A cable that looks clean but introduces voltage instability or requires excessive force to seat can cause intermittent issues that are extremely difficult to diagnose later. We verify electrical performance and physical fit before any custom cable goes into a build.
Board-Level Validation
Every PCIe slot and M.2 slot on the motherboard is tested individually. We verify that each slot is detecting devices correctly and operating at the expected bandwidth. This catches dead lanes, firmware issues, and manufacturing defects that would only surface after the system is in use.
Port & Peripheral Testing
Every USB port, audio jack, and video output is tested individually. Drive partitions are verified. Networking devices, including WiFi and Bluetooth, are checked for proper detection and connectivity. If a port exists on the system, it gets tested before it ships.
When something goes wrong, you talk to the person who built it.
There is no call center. No ticket queue. No reading from a script. If you have an issue, you reach the people directly involved in the build and assembly of your system.
That means faster diagnosis, fewer unnecessary steps, and solutions that actually fit the problem. We know your build because we built it.
Direct communication. Email or call. We respond personally, usually within one business day.
Flexible resolutions. As a small operation, we are not locked into rigid warranty scripts. If a component fails and a cross-ship makes more sense than waiting for RMA, we can do that. If you were already considering an upgrade to that component, we can provide a credit towards the upgrade instead of forcing a like-for-like replacement.
Upgrade-friendly warranty. If you upgrade your system during the warranty period, we still honor the warranty on the original part, including labor, even if you use it elsewhere. If something is damaged during a self-upgrade, there may be a cost to restore it to working and warrantable condition, but our primary goal is for things to work, not to find reasons to deny a claim.
Component-level knowledge. We track what went into your build. If a part has a known issue or a manufacturer recall, we can proactively reach out before you even notice a problem.
Local service available. In the Raleigh-Durham area, we can coordinate in-person pickup for hands-on diagnosis when remote troubleshooting is not enough.
We are driven to improve every part of this business. Build quality, pricing, warranty terms, tooling, testing methodology, communication, to name only a few. None of it is finished. None of it will ever be finished. That is the point.
