- Zero RPM fan mode enables silent low-load operation
- Resonant LLC topology with DC-to-DC for clean power
- TFX form factor fits compact 500 W builds
Compact TFX design for slim builds
This 500 W TFX power supply fits small-form-factor cases that require the thinner profile. It delivers Modern Standby compatibility for extremely fast wake-from-sleep times and better low-load efficiency. The unit suits builders upgrading branded desktops or assembling custom compact systems.
80 PLUS Gold efficiency with semi-passive cooling
Gold certification means high efficiency operation for lower power consumption, less noise, and cooler temperatures. A Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion provides clean power, reduces coil whine, and supports more energy efficient sleep states.
Broad model compatibility for replacement scenarios
The supplier title lists compatibility with TFX 310, 410, 510, 610, 700, 710 and 10-pin units such as PA-2181-2, PCG010, PCH015 and PCJ007. Builders needing higher wattage or a standard ATX footprint should look elsewhere. No modular cables or RGB lighting are included.

Questions about this item
How do I install the 10-pin connector on this TFX power supply, and what step is often missed?
Align the 10-pin plug with the motherboard header and press until it clicks; the step often missed is seating the locking tab fully so the connector cannot pull loose under vibration.
What maintenance or replacement will this 500W TFX unit need later?
The Zero RPM fan mode reduces bearing wear, but after several years the 80 PLUS Gold efficiency may drift; plan to replace the unit if voltages fall outside ATX limits or fan noise returns at low load.
What limit appears first on this FSP500-20TGBAB during sustained full-load use?
The 500 W continuous rating is the first ceiling; the resonant LLC topology with DC-to-DC conversion maintains regulation up to that point, but prolonged operation at the maximum will trigger over-temperature protection before any other limit.
