Server PSU for legacy 20-pin builds

The Sparkle FSP300-601U is a 300W single power supply built to the ATX and ATX12V standard. It uses a 20-pin main connector and delivers +3.3V at 20A, +5V at 25A and +12V at 16A. The unit accepts 90-264V input at 47-63Hz for worldwide rack deployment.

Sustained load behaviour with dual fans

Two internal fans run under thermal speed control to keep noise low while the supply operates at full load up to 40°C. Efficiency is rated at 68% under maximum output with active power factor correction meeting EN61000-3-2. MTBF reaches 100000 hours at 25°C and hold-up time is 17ms minimum.

Replaces older 20-pin ATX units

This supply fits servers and workstations that still require a 20-pin main connector rather than the newer 24-pin design. The jump is worth it when the original unit has failed or when ripple and noise have risen beyond spec. It does not suit builds needing redundant power or 24-pin motherboards.

Perguntas sobre este artigo

How loud is the dual-fan cooling at full 300 W load?

Two internal 12 V DC fans run under thermal speed control; the Noise Killer function slows them when temperatures allow, keeping acoustic output low during continuous operation.

Which motherboard power connector does the 20-pin main lead fit?

The supply terminates in a 20-pin ATX main connector, so the host board must provide a matching 20-pin socket or a 24-pin socket that accepts the 20-pin plug.

Will the 90–264 V auto-range input work with my existing 230 V rack PDU?

Yes — the unit accepts 90 to 264 V at 47–63 Hz and draws 3 A at 230 V, so it connects directly to standard 230 V rack power distribution without a selector switch.
