KHACHIMO

KHACHIMO 600 G2 800 G2 SFF 200W PS-4201-1HB power supply

SKU CH-GCY5-P7T3H

ATX power supply compatible with HP 600 G2 and 800 G2 SFF desktops, delivering 200 W with 80 PLUS Gold efficiency and a Zero RPM fan mode for silent low-load operation

  • TypeATX
  • Modern Standby compatible for near-instant wake from sleep
  • 80 PLUS Gold certified for high efficiency and lower heat
  • Zero RPM fan mode keeps the unit silent at low loads
  • Resonant LLC topology with DC-to-DC conversion delivers clean, stable power
  • 200 W ATX power supply fits HP 600 G2 and 800 G2 SFF systems

Target System Compatibility

This power supply is built for HP EliteDesk 600 G2 and 800 G2 small-form-factor desktops. It replaces the original 200 W unit using the proprietary PS-4201-1HB connector layout. Off-the-shelf ATX units will not fit these chassis, so this model is the direct replacement for owners of those specific PCs.

Proprietary Form Factor

The single specification that determines fit is the custom SFF housing and pin-out identified by part numbers 796420-001 and 796350-001. Standard ATX dimensions and main-power connectors are incompatible with the 600 G2 and 800 G2 cases. Verify the HP part number on your existing unit before ordering.

200 W Continuous Output

The 200 W rating supports the factory CPU, integrated graphics, a single SSD and typical office peripherals. Adding a discrete graphics card, multiple spinning drives or high-wattage processors will exceed the available headroom. Systems that require more power need a different chassis and a standard ATX power supply.

Questions about this item

What does the 200W rating mean for a small-form-factor desktop?

It supplies up to 200 watts to the motherboard, CPU and drives in an SFF chassis, matching the original HP 600 G2 and 800 G2 power budgets.

How does the ATX type affect compatibility with the target HP models?

The unit uses the standard ATX electrical specification but is built to the reduced depth and connector layout required by the 600 G2 and 800 G2 SFF cases.

What mounting points and dimensions does the PSU need to fit the SFF case?

It aligns with the proprietary screw pattern and short chassis depth of the HP 600 G2 and 800 G2 small-form-factor enclosures.
