Power supply for workstation xw4600

[AugustusXie]

Want to upgrade my old workstation xw4600 with a 550w power supply. But can never boot. Heard that the 24pin on the motherboard is different from normal PCs, can anyone provide the definition of this 24pin? Or where can i find a suitable power supply?

the xw4600 is not ATX compatible, the pinout can be found the the HP xw4600 service manual

you can do a xeon  xw3363cpu mod on this system here's a link to a pre modded cpu that does not require the socket to be modded

Hi thanks a lot! Is it possible that there is a ATX-size power supply that support this workstation? Im shifting its motherboard to a new case, and the original one is too large. And those on ebay seems to be the same size as mine. And i cannot find the pin specs on

in regards to the power pinout.........................it's in the service manual (same as xw6600 as i recall)

only 3 pins are different 2/23 and a 3rd i think, personally i strongly recommend you spend the 20.00 for the correct HP unit
