The secondary market
runs on blind trust.
We end that.
Assurd Techlabs is an independent forensic certification authority. We do not buy or sell hardware. We subject it to rigorous scientific analysis and issue cryptographically signed Digital Certificates that any buyer can verify, for any unit, at any time.
The Problem
The pre-owned hardware
market is broken.
It operates on blind trust, vague descriptions, and the constant fear of hidden damage — mining abuse, thermal degradation, flashed firmware, dying VRMs. A seller can hand you a passing 3DMark screenshot and a GPU that will fail in 40 minutes under real load.
Buyers take leaps of faith. Honest sellers cannot prove the actual value of their pristine hardware. The information asymmetry destroys value on both sides of the transaction.

What We Are
Four principles that
do not bend.
Independent
We do not buy or sell hardware. We have no financial interest in the outcome of a certification. Our only product is an accurate verdict.
Forensic
Our methods are derived from electrical engineering principles, not marketing benchmarks. Every metric has a physical basis and a documented failure signature.
Cryptographic
Certificates are SHA-256 signed with the extracted ROM hash embedded. They cannot be transferred to a different unit, tampered with, or counterfeited.
Public
Every certificate is published to a searchable public registry. Any buyer can verify any unit before purchase, with no account required.
The Pipeline
Five mandatory phases.
No shortcuts.
Every submitted GPU passes through all five phases in sequence. A failure at any Hard Limit terminates the process. The unit does not proceed.
Physical Forensics
Microscopic PCB inspection, 4-wire Kelvin rail resistance measurement, and power connector assessment before any power is applied. A short on the 12V rail means immediate quarantine.
Silicon DNA Match
We extract the VBIOS binary directly via hardware SPI reader — not software — and SHA-256 hash it against our registry. Spoofed hardware, mining firmware, and board ID fraud are caught here.
1800-Second Thermal Trace
A 30-minute forensic heat soak at 1-second polling intervals. We wait for true thermal equilibrium. The Core-to-Hotspot delta is our primary thermal interface material health diagnostic.
Compute & Gaming Validation
Frametime distributions, not benchmark scores. Tensor core throughput. NVML lifetime ECC error counters. Blender render output hash verification. We test the things sellers cannot fake.
Digital Certificate Issuance
The Rules Engine — not the technician — assigns a Hardware Grade (Platinum, Gold, Silver, Bronze, or Fail). A SHA-256–signed Digital Certificate is issued to the public registry as an immutable Digital Twin of the asset.
Trust, mathematically
proven.
Whether you are a buyer eliminating risk or a seller maximising resale value, an Assurd Certificate is the only proof of hardware health that cannot be faked.
