Whatsminer M50S+ Repair — Professional ASIC Repair by D-Central
The MicroBT Whatsminer M50S+ is the enhanced variant of the M50 series, pushing hashrate to 140–146 TH/s while improving efficiency to approximately 24 J/TH. Built on the same Samsung 5nm ASIC platform as the M50S but with binned, higher-performing chips, the M50S+ delivers more hashrate per watt — making it a popular choice for miners optimizing their power-to-hashrate ratio. With power consumption around 3,312–3,408W across three hashboards, this machine packs serious performance into the standard Whatsminer form factor.
D-Central Technologies has been repairing ASIC miners since 2016. As Canada’s leading Bitcoin mining repair shop — the original Bitcoin Mining Hackers — we have extensive experience with the entire Whatsminer M50 family. The M50S+ shares the same board layout, chip architecture, and integrated PSU design as the M50S, but the higher operating frequencies and tighter voltage margins mean that failure modes can be more aggressive. Our technicians have the test fixtures, diagnostic tools, and component inventory to handle every M50S+ issue efficiently.

Common Whatsminer M50S+ Issues and Symptoms
The M50S+ is essentially a higher-clocked M50S, which means it inherits the same failure modes but with tighter margins. The chips run hotter and the voltage regulation works harder. Here are the issues we see most often:
Hashboard Failures
The most frequent M50S+ repair. The higher-binned chips in the M50S+ run at elevated frequencies, which increases thermal stress on the solder joints and chip packaging. Symptoms include missing hashboards, reduced chip counts in diagnostic reports, and abnormally low hashrate. Root causes include ASIC chip failures, broken signal traces in the serial communication chain, voltage regulator faults, and temperature sensor failures. A single dead chip can break the downstream signal chain, making the entire board report as failed when only one component needs replacement.
Overheating and Thermal Throttling
The M50S+ generates more heat per board than the base M50S due to higher clock speeds. This makes the thermal management system even more critical. Degraded thermal paste, dusty heatsinks, operating above 35°C ambient, or fans running below full speed can all push chip temperatures past the safety threshold, triggering automatic shutdowns or hashrate throttling. The tighter thermal margins of the M50S+ mean that issues which might cause minor performance drops on an M50S can cause complete shutdowns on the M50S+.
Fan Failures and Error Codes
Fan-related errors are common across the M50 family and the M50S+ is no exception. The dual-fan cooling system must operate at peak efficiency to keep the higher-performance chips within safe temperature ranges. Worn bearings, damaged connectors, and fan controller faults all trigger error codes and protective shutdowns.
Integrated PSU Failures
The M50S+ draws slightly more power than the M50S, which puts additional stress on the integrated power supply. Capacitor degradation, MOSFET failures, and rectifier circuit issues can cause the unit to fail to power on, operate unstably under load, or trip breakers. Input voltage instability on the AC line accelerates these failures.
Control Board and Firmware Issues
Firmware corruption, NAND flash degradation, and control board communication failures present the same way as on the M50S — boot failures, hashboard detection errors, network connectivity loss, and erratic behavior. The WhatsMiner Tool handles many firmware issues, but hardware-level control board faults require physical diagnosis and repair.
Our Repair Process
Every Whatsminer M50S+ that arrives at our Laval, Quebec facility goes through a systematic repair workflow designed to maximize uptime and minimize cost:
1. Intake and Visual Inspection
We log your unit, photograph its condition, and perform a thorough visual inspection for obvious damage — burnt components, corroded connectors, physical impact marks, dust accumulation, and heatsink condition.
2. Full Diagnostic Testing
We power up the unit on our test bench with calibrated power and run complete diagnostics using the WhatsMiner diagnostic firmware and test fixtures: chip enumeration on each hashboard, voltage domain measurements, temperature sensor validation, fan speed testing, control board communication checks, and PSU output verification. This identifies every fault — not just the obvious one.
3. Detailed Quote
You receive a clear breakdown of what is wrong, what needs to be replaced or repaired, the cost, and the estimated turnaround time. No surprises. You approve the repair before we begin any work.
4. Board-Level Repair
Our technicians perform component-level repairs: ASIC chip replacement, voltage regulator repair, signal trace restoration, temperature sensor replacement, thermal paste reapplication, and heatsink reattachment. We use genuine MicroBT components and professional rework stations designed for the M50 series board layout.
5. Post-Repair Testing
Every repaired board is tested on our Whatsminer series test fixtures — first immediately after repair, then again after a cooling cycle — to confirm stable operation. The full unit is then run for an extended burn-in period to verify sustained hashrate, stable temperatures, and correct chip enumeration across all hashboards.
6. Return Shipping
Your repaired Whatsminer M50S+ is securely packaged and shipped back to you with documentation of all work performed.
Repair Pricing
Repair costs vary based on the nature and extent of the fault. A firmware reflash or fan replacement costs significantly less than multi-chip hashboard repair. Typical repairs range from $65 (diagnostics only) to $300 for complex board-level work. We provide exact quotes after diagnostic testing — no guesswork, no hidden fees.

Frequently Asked Questions
What is the typical turnaround time for a Whatsminer M50S+ repair?
Most repairs are completed within 5–10 business days after we receive your unit. Simple issues like fan replacements or firmware reflashes can be done in 1–2 days. Complex multi-chip hashboard repairs may take up to 2 weeks depending on parts availability and repair queue volume. We provide an estimated timeline with your quote.
Do you offer a warranty on Whatsminer M50S+ repairs?
Yes. All repairs include a 3-month warranty covering the specific work performed. If the same fault recurs within the warranty period, we repair it again at no additional cost. The warranty covers our workmanship and the replacement components we install.
How do I ship my Whatsminer M50S+ to D-Central for repair?
Contact us first to initiate a repair request. We will provide shipping instructions and our facility address in Laval, Quebec. Pack your miner securely in its original packaging if possible, or use a sturdy box with ample foam padding. Include a note describing the symptoms you have observed.
How much does a Whatsminer M50S+ repair typically cost?
Costs depend on the diagnosis. A firmware reflash or fan replacement might run $50–$100. Single-chip hashboard repair typically ranges $95–$195. Complex board repairs or PSU rebuilds can reach $300+. We always provide an exact quote after diagnostics — you approve before we proceed. Use our ASIC Repair Cost Estimator for a preliminary estimate.
The Whatsminer M50S+ has an integrated PSU — can you repair it?
Yes. Unlike Antminers that use external power supplies, the Whatsminer M50S+ integrates the PSU into the unit chassis. Our technicians are experienced with the Whatsminer integrated PSU design and can diagnose and repair power delivery issues including failed capacitors, MOSFETs, and rectifier circuits at the component level.
My Whatsminer M50S+ shows fewer chips than expected — is it a chip failure or signal issue?
When the miner reports finding fewer ASIC chips than expected on a hashboard, it can be either a dead chip breaking the serial signal chain or a voltage domain fault. Our diagnostics trace the signal path — RXD and TXD signals at 1.8V, CLK at 0.9V — to pinpoint the exact failure point without replacing chips unnecessarily.
Do you repair individual hashboards, or only full units?
Both. You can send a single hashboard if you have already isolated the faulty board, or send the complete miner and let our diagnostics identify the problem. We also sell replacement hashboards and control boards if you prefer a swap rather than a repair.
