320W PSU for HP Micro Towers
This 320-watt power supply replaces original units in HP 6000, 6200, 6300, 8000, 8200 and 8300 micro-tower desktops as well as Z200 and Z210 workstations. It accepts 100-240 V input at 50-60 Hz and uses a 6+6+4-pin connector layout. The unit is new and tested before shipment.
Suits owners of listed HP MT and Z200 models
It fits the exact part numbers 503377-001, 503378-001, 702306-002, 702454-001, 508154-001, 611483-001, 613746-001 and 611484-001. Builders working with other chassis form factors or proprietary pin-outs should verify compatibility before ordering.
6+6+4-pin connector configuration
This single connector arrangement determines whether the PSU mates with the motherboard and drive backplane in the target HP systems. Confirm the pin-out matches the original unit before installation.

Questions about this item
Will the fan or capacitors in this 320W unit need replacement after long-term use?
The PSU is tested before shipment and uses standard electrolytic capacitors and a sleeve-bearing fan; typical service life is several years under normal loads, and the fan can be swapped with a same-size 12 V unit if it becomes noisy.
What limits continuous output when the supply runs at full 320 W for hours?
The 320 W rating is the maximum combined output across all rails; sustained loads at that level are constrained by the 4 A input current limit at 100 V and the thermal capacity of the heatsinks inside the micro-tower chassis.
How much heat and noise does the PSU produce when powering a workstation all day?
At typical loads the 320 W unit draws up to 4 A at 100–240 V, exhausting warm air through the rear grille; fan noise is audible but comparable to the original HP micro-tower supply and stays within the chassis thermal design.
