Need help finding PSU (Power Supply Unit) for HP z400

[xthatonenamex]

Hi, I'm looking for a better PSU for my z400 workstation. According to the spare part website for this machine, there are two that work. I want the 600w PSU. The problem is I cannot find it anywhere! except some fishy out of the country places that are overpricing the unit. I know the manufacturer no longer makes this. I tried looking on the HP spare part website. It exists but I can not buy it from there. If someone could link me to a website to it that would be amazing. Thanks!

I can't seem to find a good priced one either, but did manage to find a normal PSU adapter that will take the 24-pin ATX from a standard PSU and conver to the non-standard HP motherword 24-pin input.

Thanks for the link. But this isn't going to work. The Z400 is one of those desktops that are not standard ATX. Therefore being that any ATX PSU will not likely fit the z400 case. The wires may be too short to long may not work etc. I did look at the adapter. It's just not what I'm hoping to find. Thanks for responding.

The HP Z400 uses a 4 pin CPU connector instead of an 8 pin which is OK except to get the extra power they added 2- 12V. wires to the 24 pin connector.
If you get the pinout you can take the extra 2-12V. wires from the extra cpu connector and add them to the 24 pin.
You might try here.

I didn't find the PSU I was hoping to find on the link you sent me. Thanks for responding

Here's the deal with that.

You can use an ATX PSU with the adapter, or you can add 12V. to pin 12, and pin 23 yourself.

OK, gotcha. Just to clarify sorry for my stupidity. So I can use ANY ATX PSU I want as long as I have that adapter, correct?

would this one work?

I haven't done that mod myself but that's how the HP workstation modders do it.
You can ask in the TPU Dell Workstation forum. There are a couple guys with HP Z400 there.

I thought you said that ATX PSU wouldn't fit?

You told me I could get an adapter for a PSU. You didn't state which one I could use the adapter on. So I assumed you met a standard ATX PSU.

The posts I've seen were for using a standard ATX PSU. I'm personally into modding Dells and the Dell PSUs are all slightly bigger than ATX so it's a 1 way swap ATX fits Dell but Dell doesn't fit ATX. ATX PSUs are all the same height and width but the depth varies with power rating. Measure yours and make sure you get one that fits. But a Z400 should have pretty big PSU. Z400 is actually much closer to ATX layout than the Dell T3500.

OK, so I measured the PSU. The measurements are kinda close. But the width (If I measured correctly) is off

ATX width: 5.91 inch
Z400 width 4.5 (give or take a few decimals.)

The one you have in your link is a standard ATX PSU. You're right, I meant a standard ATX PSU. I'm just a little confused when you said that an ATX PSU won't work, then ask if an ATX PSU will work or not.

Sorry about that. It should work but the dimensions of the ATX PSU are off. And I'm worried it might not fit. The width length of the atx is longer than the one in my z400 right now.

You could try a SFX power supply such as some of the ones on this page:
https://www.amazon.com/Corsair-SF600-Certified-Modular-Supply/dp/B01CGI5M24

They have the same capabilities and ports as normal ATX PSUs but come in a smaller form factor.

OK so I did more measuring and everything should fit. But the width of that SFX wow. 2.5 inches mine is 4.5. But that shouldn't be a problem. I'm going to look for more SFX PSU and see if I can find any better ones.

Seasonic, Silverstone, and FSP are the other brands I would be looking at. There is a lot of junk out there so be careful.

OK, I order an SFX PSU and the adapter. I'll respond once again when they both arrive and keep you guys updated on the progress.

Ok, the adapter is arriving today. I just took out the main PSU from the Z400 and put it up to the SFX. And I was like “wow”. I knew this fax was small but. Not that small! Geez lol. I’ll post when it’s in the z400
