What power supply can i change inside HP elite system?

[XiLI]

Hello, yesterday i was asking about changing the GPU inside a HP elite system

i got HP Elite 8300 microtower
(this system: http://www8.hp.com/emea_middle_east/en/products/desktops/product-detail.html?oid=5232859#!tab=specs)

i dont know what power supply will fit into this computer since the power settings are bit differant.
what should i buy?

thanks in advance!

It says Mini tower, but im not sure whether its mini-itx or mini atx. I really recommend opening us the case and measuring dimensions, just so the power supply you get doesnt have to be returned if its too small or too big.

its a micro tower. i cant tell you if this is an ATX or Mini-ATX since i just dont know what hp use inside their systems.

edit - this is the PC - sorry about the mistake in the first note:

HP uses standard off the shelf components so any modern PSU will work. Your biggest problem is going to be space inside the case, take off the side panel and get measurements of how large your current PSU is and how much space you have to work with. A standard sized PSU is 5.5" x 5.9" x 3.4", but HPs often place the PSU really close to the drive bay so if it has a larger bundle of cables it may not fit, but without pics of the innards there is no real way to tell.

ok, got the things you need. the dimension of my supply power is 15cm x 15cm x 10cm, which in inch are: 5.9 x 5.9 x 3.9.

Plenty of space! And it takes a standard opening.


Unfortunately it looks like HP has gone back to using non-standard equipment :/ This is extremely disappointing.

Normally the PSU would connect to a 24 pin and a 4/8 pin connector on the motherboard, it looks like yours has a 4 pin, a 5 pin, and 2 6 pin connectors and those are just the ones i can see. That unfortunately means you are stuck with whatever HP will sell you 🙁

That proprietary motherboard uses only +12 Volts and -12V DC power. Even the standby power is +12Vsb.

The power supply only outputs:

+12.1 Vmain @ 16A MAX
+12.1Vcpu @ 14A MAX
-12V @ 0.15A MAX
+12Vsb @ 1.3A MAX

There are no other voltage rails.

its seems like the guy from upper comment is right. there is no 5 pin nor 2 6 pin in this case

i did extra research and unplugged all the power cables from the mobo and checked them one by one. here you can see all the power cables this PSU gives:

the only problemtic cable i find is this one - seems like some kind of low voltage cable, with 4 fibers that connected into plug of 6. this is wierd, i never seen one like this before:

last one is the power supply text, maybe it would help you figure out more:

any ideas?

As I've already said, that PSU only outputs +12V and -12V and nothing else.

It is not an ATX12V spec PSU. It is totally proprietary.

so what should i do? am i stuck with this one?

You're learning what others have experienced when trying to upgrade the PSU in their HP Elite 8300.

Proprietary means no upgrade path.

If you're knowledgeable about electronics and have the tools you can modify an ATX12V PSU to work with the HP Elite 8300 but it's not worth it.

alright, got it. thanks for the help.

This is a bit late for this thread but in case anyone else is looking for this solution.

It is possible to construct an adapter to use a standard ATX power supply with these PCs but it does have a piece of active electronics in it. The connector that looks like a pcie connector has 12V, GND, 12VSB, and -12V. The other connector is NC, GND, PSON, PSOK, TAC, FanCtl

I connected all of the wires to their corresponding connection on the 24pin ATX Connector with the exception of the 12VSB which uses a DC Boost Regulator Module to boost the 5VSB to 12V.

on the 6 pin fan header connection only 3 wires are needed, the PSON, PSOK, and the TAC, the TAC can get wired to the tach lead on the CPU Fan to disable the PS Fan FAIL message in the Bios.

the CPU power connector is a standard P4 power connection.

The above being said, the construction and use of the above adapter is at your own risk.

I used an mt3608 boost regulator module vin+ to ATX 5VSB, vin- to ATX GND Vout+ to 12VSB.
