Ruth's sister H240AS-02 internal power cable

SKU CH-R8ZT-YF1AZ

240 W non-modular server power supply with 8-pin and 4-pin SFF connectors for 3040, 3650, 3656, 5040 and 7040 SFF systems

  • 240W output powers compatible Dell SFF servers
  • 100-264V input suits global mains supplies
  • Passive PFC keeps internal design simple
  • 4-pin CPU plus 8-pin SFF connectors included
  • Fits part numbers THRJK H62JR and 4GTN5

240 W SFF Server Power Supply

This 240 W server power supply fits small-form-factor systems including the 3040, 3650, 3656, 5040 and 7040 models. It delivers up to 240 W from a 100–264 V AC input and uses passive power-factor correction. The non-modular unit provides one 8-pin SFF power connector and one 4-pin SFF power connector.

Sustained Load Behaviour

Under continuous operation the unit maintains its rated 240 W output without a modular cable interface to add resistance. Passive PFC means the power factor varies with load, so the supply draws higher apparent current at full load than an active-PFC design would. The fixed 8-pin and 4-pin SFF cables keep voltage drop consistent across the harness.

Compatibility Deciding Factor

The supply is mechanically and electrically keyed for the listed SFF chassis and matches part numbers such as THRJK, H62JR and 4GTN5. Builders using a different form factor or a motherboard that requires a 24-pin ATX connector cannot use this unit. No PCIe power connectors are present, so discrete graphics cards requiring supplemental power are not supported.

Questions about this item

How much heat or noise does the 240 W PSU produce when running continuously in a small-form-factor chassis?

The unit uses passive PFC and a non-modular design rated for 240 W maximum output; actual heat and acoustic levels depend on the host system's airflow and load.

What existing connectors must my motherboard provide for the H240AS-02 to function?

Your board needs one 8-pin SFF power connector and one 4-pin SFF power connector, plus a 4-pin CPU power header.

Will this PSU work with a Dell OptiPlex 3040 SFF that currently uses a THRJK unit?

Yes — the H240AS-02 lists the 3040 SFF and part number THRJK among its compatible models and part numbers.
