What the Service Includes
The motherboard power delivery repair service includes full diagnostics and restoration of CPU, memory, chipset, and peripheral power elements. Performed: - visual VRM zone inspection: MOSFET overheating, choke scorching, swollen/leaking capacitors, darkened textolite; - voltage measurements with multimeter and oscilloscope: Vcore, VSOC, VDD, VDDQ, VCCSA, 1.8 V, 3.3 V, 5 V, 12 V under load and idle; - MOSFET diagnostics (short, open, failure) in CPU, DRAM, SOC circuits; - choke testing for open circuit and interwinding shorts; - capacitor testing (ESR meter, capacitance mode); - replacement of faulty components: MOSFETs (N/P-channel, 40–100 V, 50–200 A), chokes (0.1–1 µH), polymer/ceramic capacitors (10–470 µF, 2.5–25 V); - trace and solder joint restoration after shorts, multilayer board rework; - flux removal, protective coating on repaired areas; - load testing: AIDA64 System Stability, Prime95 Small FFTs + FurMark, HWiNFO voltage/temp monitoring, stability check at max CPU TDP. In Khmelnytskyi we use original or high-quality equivalent components (Infineon, Vishay, Onsemi MOSFETs, Wurth, Coilcraft chokes), perform repair without textolite damage. The service often combines with PC repair, laptop repair, or CPU replacement.
When the Service is Needed
Motherboard power delivery repair is required for any CPU, memory, or chipset power issues. Main signs: - PC fails to power on or shuts down 1–5 seconds after start; - random reboots under load (games, Cinebench, Prime95); - high VRM temperatures (over 100–120 °C) even at stock clocks; - Vcore voltage droops below 1.0–1.1 V under load (HWiNFO shows); - WHEA_UNCORRECTABLE_ERROR, CLOCK_WATCHDOG_TIMEOUT, BSOD from unstable power; - system cannot sustain overclock or XMP/EXPO memory profiles; - burnt smell, darkening or scorching in VRM zone, swollen capacitors; - after power surge, lightning, failed overclock, or short circuit. Problems most often occur on mid-range and budget boards with weak VRM cooling (4–6 phases without doubling) when using high-end CPUs (i9-13900K/14900K, Ryzen 9 7950X/9950X). In Khmelnytskyi Grade recommends service at first signs of power instability to prevent total board failure or expensive CPU damage.
Work Stages
- Diagnostics: VRM visual inspection, voltage measurements under load, oscilloscope ripple check, MOSFET/capacitor testing.
- Cooler & component disassembly: VRM heatsink removal, power disconnection for access.
- Faulty component replacement: desoldering failed MOSFETs, chokes, capacitors, installing new ones with matching specs.
- Trace restoration: resoldering broken traces, multilayer connection repair.
- Cleaning & coating: flux removal, protective lacquer on repaired areas.
- Reassembly & basic testing: cooler installation, idle voltage check, POST boot.
- Load testing: AIDA64 + Prime95 + FurMark 1–2 hours, HWiNFO monitoring (VRM temps <100 °C, stable voltages).
- Final validation: system stability, max TDP CPU operation, usage recommendations.
Repair uses professional soldering station, oscilloscope, and quality components.
