My Avalon Nano 3S Stopped Working! Here’s How I Fixed Them

Replacement Avalon Nano 3S power supplies provided by Altair Tech 👉 Use code RPM for 1% off 🔗 Link for PSU https://altairtech.io/product/nano-3s-psu/aff/6/ My Avalon Nano 3S miners completely stopped working after running 24/7 for over a year. At first, I thought they were dead for good… but it turns out the issue was something way simpler. In this video, I troubleshoot two non-working Avalon Nano 3S units, test the original stock power supplies, and show why they fail over time. I then install brand-new replacement power bricks and bring both Nano 3S miners back to life. I also test USB to Ethernet vs Wi-Fi, compare latency while solo mining Bitcoin Cash on my own local node (Umbrel OS), and measure how hot these power supplies actually get — which may explain why so many Nano 3S PSUs are dying. If your Avalon Nano 3S won’t turn on, this video might save you a lot of time (and money). 🔧 What’s covered in this video: - Avalon Nano 3S not powering on (diagnosis) - Stock Nano 3S power supply failure - Replacing the Avalon Nano 3S PSU - Power supply overheating issues - USB Ethernet vs Wi-Fi latency test - Solo mining Bitcoin Cash on a local node - Cooling recommendations for Nano 3S power bricks ⚠️ Disclaimer Always ensure proper cooling for power supplies running 24/7. Power bars and surge strips are not recommended for continuous high loads. ⛏ Altair Technology https://altairtech.io/aff/6/ use code RPM for 1% OFF on ASIC Mining hardware parts, accessories and ASIC miners! 🚀 Bitaxe Gamma's and other SOLO Bitcoin Miners! https://geni.us/Ddn1Mmz code RPM for 5% off! 💾 Tangem Cold Storage Crypto Wallet https://geni.us/jBDd use code RPM for 10% off! 💻 RTX 5090's https://geni.us/nOmSUfh (PAID LINK) Chapters: 0:00 Avalon Nano 3S Not Turning On – What Happened 0:08 Two Nano3S Miners Dead After 1 Year of 24/7 Use 0:42 Testing the Original Stock Power Supplies 1:52 LED On but Nano3S Won’t Power Up 3:07 Both Stock Power Bricks Appear Dead 3:42 New Avalon Nano3S Power Supplies from Altterate Tech 4:50 Installing the New Power Supply First Test 5:07 Nano3S Powers On PSU Was the Problem 5:25 Solo Mining Bitcoin Cash on My Own Node (Umbrel) 6:08 Power Draw & Initial Ramp-Up 6:15 Testing the Second Nano3S with New PSU 6:59 Second Nano3S Successfully Powers On 7:18 Power Supply Heat Concerns 7:26 Switching from Wi-Fi to USB Ethernet Adapter 8:03 LAN Connection Confirmed (Lower Latency) 8:38 Comparing LAN vs Wi-Fi Mining Latency 9:52 Current Solo Mining Setup Overview 10:14 Measuring Power Supply Temperatures 10:49 Why Stock Power Supplies Fail Over Time 11:01 Cooling Recommendations for Nano3S Power Bricks 11:24 Final Thoughts & Fix Summary 11:39 Where to Buy Replacement Power Supplies 11:50 Back to Solo Mining Bitcoin Cash 🎯 #AvalonNano3S #BitcoinMining #CryptoMining #SoloMining #BitcoinCash #BCHMining #ASICMiner #MiningRig #HomeMining #MiningHardware #ASICRepair #CryptoMiner #Umbrel #BitcoinNode #MiningSetup #PowerSupplyFailure #TechRepair
