Hi everyone.

I want to upgrade HP Compaq 6000 Pro Microtower PSU which has 320W. I want to upgrade in order to accommodate the right wattage for my MSI GTX650.

The problem is that no standard unit with what looks like HP proprietary P1, P2 & P3 outputs.


Here is the model of my desktop: http://bizsupport1.austin.hp.com/bc/docs/s...0/c01883660.pdf


Can anyone suggest what PSU model is suitable for my dekstop?

Unfortunately, this particular PSU in your HP PC is propriety. The P1 is used to power up the mobo.
Standard PSU bought outside uses 20/24 pin design.

You will need to get back the same PSU from HP.

Is it possible right now to change the current PSU that I have? Or HP does not have any model that powers 400W and above?

I wonder how did u managed to slot in the MSI ? It is Micro Tower no?
Dont think got higher spec psu. u might try shops at low yat plaza.

It is always tricky when you get branded PCs, there will always be something in there that is propriety. And there will always be limitations of the things you could upgrade.

The link to the Illustrated Parts and Service Map to your PC shows only 320W available. Which means no other power supply other than that.

It is a Microtower PC model

yea so how did u managed to slot in the graphic card?

No. I was planning on it. I know it wont fit

Now I'm confused... yu know that it'll not fit but yet you're upgrading to power the GPU?

Hehe...I know it sounds strange to you, but I wanna override the system by sharing the power, using SATA to IDE cable. Fortunately, the GPU fits the slot, just need a little bit adjustment on its socket

Ghetto mounting the hardware? well good luck... Sharing the power from a PSU is no issue if there is enough power, but a 350W OEM PSU for a Gtx650Ti is hardly what I call enough

another option is to determine the wattage those proprietary connectors carry and solder them on a new PSU... if thats even possible

That's a custom/proprietary PSU (possibly OEM is Delta from the label layout), and a standard off-the-shelf ATX PSU will not fit at all. I would suggest dumping the rig, then get new motherboard, new casing and your desired PSU. You can move the processor, RAM, HDD and CD/DVD drive to the new machine...

Yes I know. If my calculation on the wattage is right, I can still utilize that PSU unit. Somehow I will update here whether my experiment is fruitful or not

Yes, that was my first thought but im keen on experimenting this. This thing bothers me, but somehow I will a shot by overiding the system. Will dump it once my experiment isn`t going well

Do you realize that this proprietary PSU only has 12V outputs (including the standby power)? Can see that from the ratings on the label. I don't think any amount of simple rewiring and soldering may get any off-the-shelf standard ATX PSU to work on your machine (can compare the power supply connections and you will see they are vastly different, including the standby power side). If you want to get a off-the-shelf standard ATX PSU to directly replace that proprietary PSU then some electronics knowledge is required (in other words more complex modifications, especially that standby power section). You could use off-the-shelf standard ATX PSU as a secondary PSU though (using a relay to activate power on/off control), though that PSU will be dangling outside the casing. Depending on the PSU design, some may require a minimum load to get the PSU kept switched on as well. The common ground on both PSUs also has to connected.

You are right man. But I managed to wire all these things. I ran a diagnosis for this device (GTX650) and it seemed alright. Later, I tried playing Crysis 2 and set the graphic level at hardcore setting, fortunately it handled very well but only lasted for 2-3 hours, after that it turned to a yellow glitch! Oh yes I wanna dump it or give to my siblings.
