Common symptoms include no power, random shutdowns, unexpected restarts, burning smells, clicking noises, or a computer that only starts intermittently. Professional diagnostics confirm whether the PSU is actually responsible.

Expert PC Power Supply Repair Las Vegas Service Available
A desktop computer that freezes, won't boot, randomly restarts, or performs far slower than expected doesn't always need a new motherboard. At EZ Laptop Repair, we diagnose processor failures, CPU socket damage, BIOS compatibility issues,A faulty PSU can affect far more than startup. Unstable voltage, failing 12V rails, damaged PCIe or ATX/EPS connectors, and inadequate power capacity can disrupt the CPU, GPU, motherboard, storage, and overall system stability. Our technicians check the power delivery requirements of your desktop before recommending the right solution. When replacement is needed, we match the power supply to your system's wattage demands, form factor, connector configuration, and hardware load rather than installing a one-size-fits-all unit. EZ Laptop Repair provides reliable PC power supply service in Las Vegas, with same day service available for replacements when a compatible PSU is in stock.

Top Power Supply Issues We Diagnose and Resolve
Power related PC failures appear in several different ways. Some computers won't power on at all. Others restart randomly, freeze during applications, or suddenly lose power without warning. Our Comp TIA A+ technicians diagnose the PC power delivery system to determine exactly where the problem begins.
Estimated 1 - 3 days
PC Won’t Power On
A dead desktop may include the AC input, PSU, power switch, ATX connector, or motherboard power circuit. We track the startup path to determine where power stops reaching the system. This helps distinguish a failed power supply from a motherboard or connection fault.
Estimated 1 - 3 days
Random Shutdowns During Use
Unexpected shutdowns can occur when voltage regulation becomes unstable as the CPU or GPU increases its power demand. Usually, gaming PCs shut down during heavy workloads. We review PSU output, system load, thermal conditions, and motherboard power delivery together.
Estimated 1 - 3 days
Insufficient PSU Wattage
A PSU needs enough capacity to handle the combined CPU, GPU, storage, cooling, and motherboard power requirements. EZ experts evaluate the system's estimated power consumption, PSU wattage, efficiency rating, and available headroom.
Estimated 1 - 3 days
GPU Power & PCIe Problems
Modern graphics cards rely on dedicated PCIe power connections and adequate PSU capacity during high performance workloads. Damaged cables, loose connectors, inadequate power, or an unsuitable PSU can contribute to graphics instability. We fix these as well.
Estimated 1 - 3 days
Burning Smells & Electrical Noise
A burning odor, clicking, buzzing, or abnormal fan noise indicates overheating or a failing PSU. Our techs check for electrical/heat damage and deteriorated connections to determine whether additional repairs are necessary beyond replacing the power supply or not.
Estimated 1 - 3 days
PSU Replacement for ATX, Modular & Non-Modular
If the power supply has failed, we install a PSU matched to your PC power requirements. We replace modular, semi-modular, and traditional ATX power supplies while ensuring compatibility with your CPU, graphics card, storage devices, and future upgrade requirements.
Top Signs Your PC Power Supply May Be Failing
Your gaming PC uses maximum power when the CPU and GPU are under heavy load. A PSU that is poorly matched to the system can contribute to crashes, shutdowns, and instability, even when the computer starts normally. Early PSU failing warning signs include:
- Random shutdowns during gaming or heavy workloads.
- A computer that powers on briefly before shutting off.
- Unexpected restarts without warning.
- Clicking or buzzing noises coming from the power supply.
- Burning smells near the rear of the computer case.
- The system only starts after several attempts.
- No power at all despite a working wall outlet.
Recognizing these symptoms early can prevent additional damage to expensive components such as the motherboard, graphics card, or storage drives.
How Our Power Supply Repair Process Works
Every computer follows the same structured diagnostic process. We identify the fault first, explain our findings, and only then recommend repair or replacement.
Power Diagnostic Check-In
We discuss the symptoms you’ve experienced, perform an initial inspection, and document any previous power failures, electrical events, or intermittent issues before testing begins. All this is FREE for every Las Vegas customer as part of our service.
Voltage & Load Testing
Using professional diagnostic equipment, we measure voltage stability, test load performance, inspect motherboard power delivery, and verify all major power connections. Our PC repair technicians ensure any power error is identified before we recommend a replacement.
Repair or Replacement Recommendation
If testing confirms a failed power supply, we recommend a compatible replacement. If the issue lies elsewhere, such as damaged connectors or motherboard circuitry, we explain the appropriate repair instead at market competitive rates.
Post-Repair Stability Testing
Before returning your computer, we complete burn-in testing to verify reliable startup, stable operation under load, and consistent power delivery. If any power supply part is not working the way it should, we do not return it.
Why Las Vegas Trusts Us for Power Supply Repair
Power supply is more than replacing a box inside the computer. The right service depends on technician experience, hardware knowledge, safe handling, and choosing components that suit the system. That’s what we bring to desktop, gaming PC, and custom-built computer repairs in Las Vegas.

PSU Selection Based on Your Build
A replacement power supply needs to match the computer it is going into. We consider wattage, 80 PLUS efficiency, form factor, PCIe connectors, CPU power requirements, and GPU demands when selecting compatible hardware.
3
Safe Handling of Power Hardware
Power supplies contain components that can hold a dangerous electrical charge even after being disconnected from the wall. Our technicians use appropriate safety procedures when working around the PSU, AC input, motherboard, and internal power connections.

Service Backed by Warranty
We don't consider the service finished simply because a replacement component has been installed. Our completed repairs and PSU replacements are backed by a 3 month warranty, giving you additional confidence after service.

Questions
Frequently Asked Questions
Most failed power supplies are replaced rather than repaired because replacement is generally safer and more reliable. However, damaged connectors or external wiring issues can often be repaired.
If the PSU itself has failed, replacement is typically the recommended solution. If diagnostics identify another component causing the issue, repairing that component may be sufficient.
A computer may fail to start because of a defective power supply, damaged motherboard, faulty power button, loose connector, or another electrical fault. Testing determines the exact cause.
Pricing depends on your system's required wattage, PSU quality, and compatibility requirements. We provide a clear estimate after completing diagnostics. Las Vegas PC power supply repairs are available at EZ Laptop Repair from $75.
