Compact LCD power supply tester with 20+4 pin connector and SATA ports

SMUGDESK

SMUGDESK 20+4Pin LCD Power Supply Tester SATA

SKU CH-XXSK-5FD7Q

Tests ATX, ITX and BTX power supplies via 20+4pin, PCIe and SATA connectors with real-time LCD voltage readout

  • Tests 20+4pin ATX, ITX, BTX PSUs
  • LCD shows realtime voltage for quick health check
  • Checks PCIE, SATA, HDD power rails
  • Plugandplay, no software or drivers needed
  • Compact build for PC building and repair

Portable PSU Diagnostic Tool

This compact LCD tester connects directly to 20pin and 24pin motherboard power connectors on ATX, ITX and BTX power supplies. It also accepts PCIE, SATA and HDD power plugs so technicians can verify multiple rails with one handheld device. No software or drivers are required, making it ready for immediate use on the bench or at a customer site.

Single-Rail Readout Limitation

The built-in LCD displays realtime voltage values for each connected connector, yet it cannot apply a load or measure ripple, noise or transient response. Intermittent faults that appear only under load may therefore go undetected. Users who need full stress validation will require a separate load tester or oscilloscope.

Basic Voltage Verification Coverage

The unit comfortably handles quick go/no-go checks on mainboard, graphics, SATA and HDD power outputs before a PSU is installed in a chassis. It runs out when deeper analysis such as efficiency curves, cross-load regulation or hold-up time is needed, as those measurements fall outside its passive monitoring design.

Questions about this item

Should I pick the 20pin or 24pin connector for my motherboard?

The tester includes a combined 20+4pin plug that fits both legacy 20pin and modern 24pin motherboard sockets.

What does the LCD voltage reading tell me about my power supply?

The screen shows realtime voltage on each rail so you can spot overvoltage, undervoltage or unstable output before it damages components.

Does the SATA connector test the same rails as the main 24pin?

The SATA and PCIE connectors let you check the peripheral power rails separately from the motherboard main power rails.
