Hi, first ty all for your work in this forum 😀, this is my first post but i have read quite a bit in this days, also sorry for my bad english, i hope to not make your eyes bleed ! 😅
I got interested in this little machines and ordered an hp 600 G4 SFF that should arrive in the next weeks.
Initialy supposed to be a simple office pc, inspired by some post like the one from NonSequitur777, now i would like to make it a little media device with a little gaming capability.
The first step would be to add a dedicated gpu and my choice was a cheap RX 6400 as around internet everyone seems to be able to make it works with a base 180w psu, like the one that my pc should arrive with.
However reading posts in this community seems that some people have trouble with this kind of machine and that gpu (or more in general gpu that are not on the spec sheet).
The prime suspect seems always be the psu followed by the supposed 35w pcie x16 limitation slot.

Also i don't want be on the wattage edge so i would like to upgrade the psu.

Looking on spec sheet and HP partsurfer seems that all 600 G4 SFF come with the psu with part number "L29203-001" that is the only one aviable for this machine (at least in the manual).

Doing a bit of research i learned that a lot of the hp pc come with a proprietary psu that make use of 3 connector: P1 -P2 -P3: 2x standard 4pin and a  non atx compatible 7 pin that go in the pwrcmod port.

I'm not an expert but seems that the 7 pins are:

- Black: RTN2 --> GND
- Purple: METER
- Gray: PSU_ID
- Green: PS_DN
- Black: RTN2
- White: TAC1
- Red: FAN_CMD

Now, ignoring that the wires can be orderded different, the psu can have from 3 to 7 wires.

For example, looking at some disassembly of the 600 G4 SFF, the psu seems to have the 7 pin connector with 5 wires, BUT, the psu in the hp partsurfer ("L29203-001") should have only 2 to 4 wires (this is base on the image on ebay, aliexpress, and some disassembly on youtbe).

Of this wires the first black (should be ground) and the green one (power one) are alway present (maybe the gray power good too).

If there are no mistake on partsurfer, i see that the prodesk 600 G5 SFF use the same 180w psu (even if in this case the manual says that there are 3 different psu aviable).
What i want to know if i can assume that both pc use/can use the same psu, this because i could use the 310w of this machine. On reddit (and yt) there are some people that pgrade theri 600 g5 sff 180 psu with the one with part number: Part Number: L33619-002 (Model: D18-310P1A).

A quick search (i don't know if i can link store that are not hp) on ebay/aliexpress reeal that not only the psu is a perfect fit ( 20x8.5x 5.4 cm) bt that come with the benefit of a rare 8 (6+2) pin to power dedicated gpu and possibly overcome the 35w limitation.

I ask for your help to:

1) Confirm/deny psu compatibility between hp 600 SFF G4 and G5

2)Confirm if the psu with part number L33619-002 will work with my 600 G4 SFF (and i mean at 100% not with fan error/problem like here and here)

 3) in case both 1 & 2 are yes, will drill a bit the pcie x4 slot make an Asus Dual Mini RTX 3060 12Gb work ?

@Red_J,

 

Welcome to our HP Community forum!

 

Yes, the 310-watt power supply you referenced for an HP ProDesk 600 G4 SFF is indeed a fit.  Mind you, not all 310-watt power supplies are equipped with a 6+2-pin PCIe power cable, but that is the one you want if you are interested in upgrading your power supply.

 

Here is an eBay Seller who sells the 310-watt variant you want: For HP 310W Desktop Power Supply Model: D18-310P1A Part Number: L33619-002 | eBay.

 

Mind you, an HP ProDesk 600 G4 SFF does not provide a lot of space for a graphics card, especially not for cards that requires a 6-pin or 8-pin PCIe power cable:

As far as I know, the most powerful graphics card that would be able to be powered by your PC and actually fits inside your case, is the Radeon Pro W6400 4GB GDDR6: https://www.techpowerup.com/gpu-specs/radeon-pro-w6400.c3873.

Thanks for your answer, i feel like i had done homework right  😀!

About the space my idea was to put the gpu in the upper slot in a way similar to this video.

I see that the one in the video is a prodesk MT, but in theory should work the same trimming part of the hd cage.
However i don't want to lose the dvd-drive as i think is still usefull for old pc game/emulation.
Probably the best thing i can do is wait for the actual pc to arrive and then take real measure.
Thank you for your fast answer !

Small edit: Of course gpu must be a x8 lane or performance loss will be too much in x4 slot

Almost forgot, another option for the pcie slot x16 for every sff is the Dell AMD Radeon RX 6500 4GB GDDR6 50 watt ( around 20% faster then rx 6400).

Is an oem card but can be found used on ebay for almost the same price of the rx 6400

@Red_J,

 

I salute you: that is a really outstanding slim-sized and low-profile find, a Dell AMD Radeon RX 6500 4GB, one of the most powerful low-profile, slim-lined and low-power (40-watt TDP!) graphics cards available on the market today:

Hi, sorry for the late reply, but my pc arrived much later then announced (was lost....)

Now that i have it i can tell you that the psu inside is not the one with part number "L29203-001" but the "L084044-001".
This one also appear on partsurfer using the product number on the case "2VG42AV".
This psu use a p1 (4 pin),  p3 (4 pin) and a p2 (7 pin) with 5 cable: black-violet-gray-green-black 
while the other psu we were talking about "L33619-002", use only 3 cable: black-gray-green (on some photo 4 with violet too).

Right now i was placing an order on ebay, following the link that you give me however in suggested search about "L33619-002 psu" i read a lot of "600G3 400G5 280G3"

I know that you said that should fit, but will it also electricaly fit ?

Sorry if it is a stupid question.

 

Also late happy new year 😄

@Red_J,

 

I stand by my User opinion that the 310-watt power supply with p/n: L33619-002 should be (electrically) compatible with your desktop, but I admit that there is an element of uncertainty involved here: HP is not giving me the tools to adequately ascertain without a shadow of a doubt that the aforementioned power supply is going to work for you.  For example, I couldn't even evaluate the L33619-002 (or -001/-003) part number via HP's PartSurfer:

 

NonSequitur777_0-1735926888341.png

 

Meaning, I would order the power supply from a Seller who allows for returns if the 310-watt power supply doesn't work properly.

 

Sorry, this must be as frustrating to you as it is for me, but this is what we are dealing with.

 

Kind Regards,

Thanks again for your help ! 

More then returning the psu i'm afraid to fry/soft lock with hp sure smart the motherboard.

Other listing reports strange specific generation combination like 400 g4 g5 600 g3 600g5 h280 g3 g4 g5.

Do you happen to know if there are change in how the psu works in this models ? I mean why the 180w psu should work with 600 63-4-5 while the 310w psu should skip 600 gen 4 ?

@Red_J,

 

This power supply will either work, it will not work, OR it will work but comes with an annoying 'POST' message which goes away once you clear it.  Chances that it will fry your motherboard are slim to none, at least in my experience.

 

Buying this power supply via Amazon is a good move: Amazon makes it easy/easier to return the unit and getting your money back.

 

Kind Regards,

Hi again, here for update !
Almost 3 weeks later i got the psu, not from the previous link but was the same part number.

Unfortunately it didn't work, with the new power supply the PC shows no sign of life, no fan spinning, no light turning on.
Given that the 3 cables it has are power good, ground and power on i imagine that the pc should at least do self post when connected to the mains and then turn off or show errors as it did when it had a low bios battery, but as mentioned before, nothing. i'm pretty sure the psu was dead on arrival as this machine have a constant 12v even when powered off. However the seller offered me a refund.

Since I'm now "stuck" with the default 180w PSU I think I should opt for a GPU powered by the PCIe slot only. A real shame because taking two measurements i noticed that it was quite feasible to mount a cheap used gtx 1060 6GB (ITX, lke the zotac) in the hd cage (with the compromise of having to use a USB DVD reader). Be that as it may, my current options are:

 

  • the rx 6400
  • the gtx 1650
  • the rt 3050

Given that the cpu currently installed is an i3-8100, and that the best of the upgrades are the i5-8500, the i7- 8700 (I think it's too much for the psu) and the i5-9500 (if the motherboard reads it), I think I'll buy an rx 6400 which should be fine for an emulation and light gaming PC. Imho the rx 6500 lp have reach almost 200€ on ebay and is not worth so much .

Do you think that the rx 6400 will work ? The suggested w6400 used cost even more than a brand new rx 6400
