SKU CH-S1MN-AAR3R

A 290 W internal power cable with 8-pin and 4-pin CPU connectors for OptiPlex 3020, 7020 and 9020 MT systems

  • Delivers 290 W to Dell OptiPlex 3020 7020 9020 MT
  • Active PFC corrects power factor from 100-264 V input
  • 8-pin plus 4-pin CPU connector fits proprietary motherboard layout
  • Non-modular design keeps cabling simple inside large chassis
  • Replaces part numbers 776VT RVTHD XFXKX KPRG9 NOKPM

Direct replacement for OptiPlex MT

This 290 watt internal power cable set provides an 8 pin plus 4 pin CPU connector for Dell OptiPlex 3020, 7020 and 9020 MT systems. It matches part numbers H290AM-00, L290AM-00, AC290AM-00, D290EM-00 and spare numbers RVTHD, 776VT, N0KPM, XFXKX, HYV3H, KPRG9, NOKPM. The non modular design fits the original chassis without adapter cables.

Steady output with active PFC

Active power factor correction maintains stable delivery across the 100 to 264 volt input range during continuous operation. The unit carries an 80 Plus certification tier listed as Other Certification, indicating verified efficiency under sustained load rather than only peak bursts. Zero 12 volt graphics pins mean all rated capacity stays available for the CPU and board components.

Fixed connector limits expansion

The cable harness ends in a single 8 pin and a single 4 pin CPU plug, so builders who need additional PCIe power for a discrete graphics card cannot use this unit. The proprietary pinout matches the OptiPlex MT and T1700 large chassis only; it will not fit standard ATX motherboards or smaller form factor cases. No modular cables are included for reconfiguration.

Questions about this item

How much heat does the 290W unit produce when running continuously?

The 290W rating indicates the maximum power the supply can deliver, not the heat it emits. Actual heat output depends on the load drawn by your OptiPlex 3020, 7020 or 9020 MT components. Active PFC helps maintain efficient conversion across the 100-264V input range.

Does the 8-pin plus 4-pin CPU connector require a specific motherboard header layout?

This cable combines an 8-pin and a 4-pin CPU power connector. It fits Dell OptiPlex 3020, 7020 and 9020 MT boards that use the matching 8+4 pin EPS layout. Verify your motherboard has both headers side by side before installing.

Will this PSU work with the older T1700 chassis I still use?

The supplier lists the T1700 among compatible models alongside the 3020, 7020 and 9020 MT. The 290W unit uses the same 8-pin and 4-pin CPU interface and 100-264V input, so it should power the T1700 without adapter changes.
