Manufacturer description

The Fuhengli PC Power Supply Tester turns a guessing game into a two-minute diagnostic. Plug your ATX PSU into the 20-pin or 24-pin header and the 1.8-inch LCD reports +3.3V, +5V, +12V1, -12V, 5VSB, and the PG (power-good) signal at a glance, so you can tell a genuinely dead supply from a dead motherboard before you order a replacement part. Eight connector types are covered: 20-pin ATX, 24-pin ATX, HDD/IDE, 4-pin floppy, PCI-e 6-pin, 4-pin, EPS 8-pin, and SATA. IDE, floppy, and SATA rails report through the LED row on the left edge rather than the screen, while PCI-e, 4-pin, and EPS…

SpecPicks Verdict

SpecPicks scored Fuhengli Computer PC Power Supply Tester using a rating × review-volume × price-fit model applied to published specs and reviews across the power supplies category. Fuhengli's power supplies lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for power supplies of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions

Does this tester work with PCI-e 8-pin GPU power connectors?

No. The manufacturer states it does not fit PCI-e 8-pin. It covers PCI-e 6-pin, EPS 8-pin, 4-pin, 20-pin ATX, 24-pin ATX, IDE/HDD, floppy 4-pin, and SATA.

What voltages does the LCD screen actually display?

From the 20-pin or 24-pin connector the 1.8-inch LCD shows +3.3V, +12V1, +5V, -12V, 5VSB, and PG. It does not display +12V2 from those headers. PCI-e 6-pin, 4-pin, and EPS 8-pin readings appear as +12V2.

How do I read SATA and IDE results?

Those are indicated by the LED lights on the left side, not the screen. A healthy 5-wire SATA connector lights +12V, +5V, and +3.3V; a 4-wire SATA lights only +12V and +5V. IDE/HDD and floppy each light +12V and +5V.

Why does the screen look scratched out of the box?

It is a protective film, not damage. The manufacturer applies it because the screen scratches easily, and notes you can peel it off yourself if you prefer the bare screen.

Is this a reliable buy for the price?

It is a low-cost first step before replacing a suspect supply. Check the product listing for current warranty terms.
