B2600 Power Supply Form Factor

My B2600 has the Delta Power Supply DPS320EB installed. Delta has refused to give me the voltages used on the 24-pin and 8-pin motherboard connectors so that I may troubleshoot the power supply output. I contacted HP and they will ask Delta to supply me with the pin-outs if I open up a $39.95 trouble ticket. To that I say bull$h*t! I don't want to just throw parts at my workstation and I especially won't throw $39.95 towards getting a simple answer to the question . . . "Does HP adhere to the ATX12V 2.01 Form Factor" for its power supplies and why are only 6-pins used on its 8-pin motherboard connector and what are the pin-outs?

Forgot to mention that I've got MAINBOARD: A6070-66510 REV A2
...and here is the form factor (if I can get it to post)

Re: B2600 Power Supply Form Factor

Thanks for the input. This type manual is what I'm looking for. I know they are similar (B2000 and B2600) but do you know where I can find the actual manual for the B2600 to download?

Re: B2600 Power Supply Form Factor

Upon further review, I need a more detailed diagram of the power supply pin designations for troubleshooting. While the suggested manual is fine for Field Replacemant Units, I need more detail.
Thanks

Re: B2600 Power Supply Form Factor

hi,

hp doesnt normally divulge such information and keeps most technical specifications to themselves. Its a case of trying to work the finer details out?

you may find some useful info in the tech ref manual

http://h20000.www2.hp.com/bc/docs/support/SupportManual/lpv38329/lpv38329.pdf

all manuals for the b2600 are here

http://h20000.www2.hp.com/bizsupport/TechSupport/DocumentIndex.jsp?〈=en&cc=us&contentType=SupportManual&docIndexId=179166&prodTypeId=12454&prodSeriesId=75759〈=en&cc=us

Failing that you may be better trying to source a used replacement PSU from a hp reseller

Re: B2600 Power Supply Form Factor

Good stuff Andy, thanks. Will add to my library.
Today I'm running fine (knocks on wood) but as a former tech, these intermittent faults drive me nuts. Haven't had to refrigerate my PSU at all today. Perhaps someday I'll run across the voltages and perhaps they are ATX12V compliant and I'll share it with the world. Again, Delta Electronics will tell me for $39.95
Cheers!

Re: B2600 Power Supply Form Factor

SUCCESS!!!
(well partially,excuse my enthusiasm)
While checking out my PSU fan motor connections I took the motherboard connector labels off the PSU PWB and kinda answered my own question . . . the B2600 Delta Power supply DOES NOT adhere to the ATX12V 2.01 Form Factor for the motherboard connectors. All the output voltages appear to be identical but the pins have been arranged in a different order. So now, wondering minds need to know, is having the pins rearranged constitute proprietary product coverage or was I being dealt the run-around card by Delta Electronics and the $39.95 charge for having them "tell" me the pinouts?

Re: B2600 Power Supply Form Factor

Okay guys, I've been on a mission and here are the steps in making any ATX12 Form Factor PSU work in a 785/B2600. I won't even charge $39.95 for the info. No mods were required to the B2600 chassis metal. My new, not used, PSU has a 120mm cooling fan versus the 80mm for the stock DPS-320EB.

First, stub off and cap all PSU outputs that don't go to the 24pin or 6 pin Molex motherboard connectors.
(all these extra unused 12V, 3.3V, and common, wires just interfere with air flow)
Move Pin1 to Pin13
No Changes Pin2
Move Pin3 to Pin4 (Connect any spare capped-off Orange +3.3VDC from PSU to Pin3)
Move Pin4 to Pin12
No Changes Pin5
No Changes Pin6
Move Pin7 to Pin8
Move Pin8 to Pin11
Move Pin9 to Pin7
Move Pin10 to Pin21
Move Pin11 to Pin22
Move Pin12 to Pin14
Move Pin13 to Pin1 (provides 2 separate conductors to Pin1)
Move Pin14 to Pin20
No Changes Pin15
Move Pin16 to Pin23
Move Pin17 to Pin16
Pin18 (Connect any spare capped-off Red +5VDC from PSU)
Pin19 (Connect any spare capped-off Red +5VDC from PSU)
Pin20 (N/C in ATX12, now gets ATX12 Pin14)
Pin21 (Gets ATX12 Pin10)
Pin22 (Gets ATX12 Pin11)
Pin23 (Gets ATX12 Pin16)
Pin24 (Gets 3rd wire, fan sensor, from PSU fan, wired directly)
Enjoy!

Re: B2600 Power Supply Form Factor

Forgot to add that the following pins are now vacant and need:
Pin9 (Connect any spare COM black)
Pin10 (Connect any spare COM black)
Pin17 (Connect any spare +5V Red)
Pin18 (Connect any spare +5V Red)
Pin19 (Connect any spare +5V Red)

(Sorry, now all 24 pins are accounted for on the left side and right side of my previous list)

Re: B2600 Power Supply Form Factor

hi coopers,

have you try power up the B2600 with the modified ATX12? the current rating for DPS-320EB are much hight than the ATX12.

Do you have to swap the pins on the 8-pins connector? they are the +12v and GND.

Re: B2600 Power Supply Form Factor

Haven't been on this board in a while . . . sorry . . . but the modified power supply has been running for almost 6 years now.

Where does time go???

And to answer the question on the 8 -pin connector . . . no mods were needed.

Cheers!
