Graviton 250W server power supply PC6038 PS-5251-06 TFX0250P5W

SKU CH-GE6V-RX330

250 W server power supply with 24-pin and 4-pin ATX connectors plus three SATA power leads for compatible 220S, 230S and 530S systems

  • 250 W output powers compatible servers and desktops
  • Wide 100-264 V input handles global mains voltages
  • 24-pin and 4-pin ATX connectors fit listed motherboards
  • Three 15-pin SATA connectors supply multiple drives
  • Passive PFC design meets basic power-factor requirements

250W TFX server power supply

This 250W TFX power supply targets administrators maintaining Dell OptiPlex 220S, 230S and 530S small-form-factor servers. It replaces the original PC6038 or PS-5251-06 unit and delivers 250W across 100-264V input. The non-modular cable set includes a 24-pin ATX connector, a 4-pin ATX connector, a 4-pin Berg floppy connector and three 15-pin SATA power leads.

Sustained load behaviour with passive PFC

Passive power-factor correction means the unit draws higher peak current at low line voltage, so sustained 250W output at 100V requires 8A from the mains. At 200-240V the same load draws 4A, reducing stress on upstream distribution. The supply operates across 50-60Hz without manual switching, maintaining regulation during continuous server duty rather than short bursts.

Connector limits for modern builds

Three 15-pin SATA connectors restrict the number of directly powered drives to three. No 12V graphics-card pins are present, so discrete GPU upgrades are not supported. The single 24-pin and 4-pin ATX pair serves mainstream server boards, but boards requiring an 8-pin EPS12V connector cannot be used.

Questions about this item

How much heat and noise does the 250W passive-PFC unit produce when running all day?

The 250W supply uses passive power-factor correction and a non-modular design; expect typical server PSU fan noise and warm exhaust under continuous load.

Which cables or connectors must my system already provide for this PS-5251-06 to work?

Your motherboard needs a 24-pin ATX and a 4-pin ATX socket; drives require three SATA power plugs and the floppy connector uses a 4-pin Berg.

Will the TFX0250P5W fit the 220S, 230S and 530S chassis I still use?

Yes — the part numbers 67P3M, 067P3M and CN-067P3M list 220S, 230S, 530S, 531S, 540S, 545S and 560S as compatible systems.
