I replaced the 250W HP PSU in my Elitedesk 800 G4 with a generic 400W PSU with two 4-pins, two 6+2-pin GPU, and a 7 pin connector with only 3 wires. It worked, but after re-start it seems some BIOS security feature (HP Sure Start?) is detecting non-HP hardware and preventing boot-up. It just hangs at the "Protected by HP Sure Start" screen. Anyone know what I can disable in BIOS to get it to accept non-HP hardware? Or is that what the PSU_ID pin is for maybe?

I have an HP 400 G5 and want to install an ATX power supply, but the motherboard only has 4+4 P2 pins, one for the processor and the other to the motherboard and a black and green cable connector to turn on the power supply. How would someone do it? Can someone help me?

Has anyone had problems with the PSU running power for the PC and its components while the PC is turned off? Say for example, power being fed to the GPU while the computer itself is off? To me it would seem that there is a good chance that if a power surge of somekind happends, the PSU would not be able to save components from frying when the pins:"power on" and "ground" are connected. I might be wrong though any help is appriciated!

Sounds like another youtuber called xpetu. Where is your accent from

Good day everyone. The collar moves up and down to lock the barrel if any key is installed or flat screw driver. The coller will spring up and rotate if incorrect key is used /screw driver(this is a screw driver anti theft protection) When everything is glued together any key screw driver can open that door just try it and see. But great video

I have bmw 116d diesel my car dose same when let over night is same for part my car

Hai risolto il rumore dopo aver cambiato il tenditore superiore ?

incredibly useful video, thank you.

What is this part called lol

My brother has an M01-F1055na with the same(?) 7-pin PWRCMD P2 cable, and wants an upgrade to a new 600W PSU for a 3060 Ti. I think I'm starting to make sense of it, but... from what I can tell you have to wire the P2 cable to a 24-pin ATX cable and plug that into a power supply? I think he's got just 1 4-pin, which starts at 8-pin in the HP PSU. Annoying. I see lots of 24-pin ATX to 6-pin PWRCMD adapters on Amazon, could it be possible to convert a 7-pin to a 6-pin and make that work? Aggravating that it's this ridiculous but here we are I suppose. I have a multimeter (but no idea where to check) so I'm not sure.

Thanks for the info !!!!

Paljonko oli ajettu kun vaihdoit kiristimen? Omalla N47D20C ajettu 360k ja mietin että jos tuon kiristimen vaihtaisi ihan vaan ennaltaehkäisynä. Öljyt vaihtanut 10-15k välein riippuen missä ajanut ja alkuperäinen ketju yms. osat koneessa. Väitän, jos vaihtaa öljyt aiemmin kuin long lifella muka voisi ajaa se suojelee ketjuakin.

Witam w temacie HP400 G4 SFF jeśli ktoś nie posiada wtyczki zasilania do procesora 8 -pin tylko 4 pin może wykorzystać zasilanie +12v oraz GND wychodzące z 24 pin wtyczki ja tak zrobiłem i komputer działa ,problemem jest tylko podłączenie dysków twardych niestety nie można ich podłączać do zasilacza (Corsair VS450 450W) tylko do płyty głównej bo inaczej dyski cały czas chodzą nawet po wyłączeniu płyty przyciskiem "power on " masz może na to jakieś rozwiązanie pozdrawiam

hey man, good video. Im trying to figure out simply how to power an hp prodesk g3 600, without having to use the hardwired button on the mainboard. If you have any idea id appreciate it because i,m stumped! thanks

Thanks. I was gifted a broken 10th gen i7 HP desktop. I got it working, but my investigation showed that the PSU was not adequate to supply the necessary current to the stock configuration under heavy loads. A 180 watt PSU in a system whose CPU can draw 227 watts! The voltage drop was sufficient to destroy several onboard components. I have zero desire to gift HP with the money for an upgraded power supply to fix a problem that they purposely (seemingly) create. I am still looking for an aftermarket supply with the correct pinout, but I would probably be better off following your procedure. At least then, when the computer dies, I might be able to salvage the PSU. Again, thanks.

I did mine , it fixed the startup rattle but there is a second rattle... sounds bad when you rev from 2000 to 3000 ... rpm .

Thank. This work for my HP 280 G4.

Is the on and off switch absolutely necessary?

Hi my friend thanks alot for the video One question i have an hp 400 g4 MT business pc You know that 180 watt isn't good enough for GPU like gtx 1070 ti The question is can I buy a normal ATX powersupply regarding the space and power up my hp pc or this will make my pc fried? There is an 4pin P1 4pin P3 i guess 7pin p2

will it work on shp 12 gen pwrcmd cable?

What is the name of the connector on pwrcmd? This looks like a JST PH 2.0mm 7 pin female connector? I see adapters to atx power supplies for other HP systems, but it seems no one is making adapters for these hp pavilion pwrcmd pwoer supplies yet, which lots of people seem to need.

Any sodering required? Im not too knowledgeable on all this stuff.

Hi, thank you for good solution. I've run prodesk 600 G3 sff without issues. I have 7 pin with 5 wires where only grey (pwr good) and black (gnd) is necessary to start. As there still no solution to run ATX PSU in regular way (using 5v standby) we need to keep it running (keep connected pwr-on to gnd) before power button on motherboard is pressed. As today mostly all ATX has a switch there is not necessary to add extra one (but it is definitely cool :) ) To make process more convenient i bought special cable "24Pin to 6Pin Connector for HP Elite 8100 8200 8300" from aliexpress. It has 2 connectors: 6pin power and 6 pin data. From 6 pin connector we need to connect only 4 pins (black and yellow). In general it has: 2 yellow (+12v), 2 black(GND), standby +12v and -12v. From data 6pin we need all 4 wires which are: gnd,gnd,pwr-good,pwr-on leaded to 24pin connector. I use jumper wire (like for breadbord ) to connect pwr-on to gnd. But to connect to mobo i had to cut 7 pin from stock PSU and solder grey and black to jumper wires which makes it very convenient to plug them into 6 pin data leads (gnd and pwr-good). P.S. motherboard has non standard holes layout which doesn't fit regular ATX cases. To flip the case it is easier to disassemble stock case and install it's support stamped backplate to regular case using screws or rivets. I also soldered connector to mobo's power button and connected it to the case's power button. P.P.S Case fans will run when PSU is on. To prevent it they need to be connected to sata power on mobo directly or use a relay to commute +12v from PSU to FANs. I use 5v arduino relay module which takes 5v and gnd from CD-rom cable. Here is my solution of standby mode without switch: kzbin.info/www/bejne/bmHRi5R9gZ6fjqssi=duGxxt1yVeJrIpv0

Im trying to swap psus for another 550 watt small form factor itx psu. Is the 7 pin necessary for thr pc to work cause i. Using a hp slimline mo1. Was hoping to use both cpu 4 pin and the other 4 pin and call it a day. Please respond if possible

Amazingly useful thanks. It's ridiculous that HP do this, so anti-consumer.

I just did this on an HP envy desktop! (like literally just now so I guess TBD whether it stays stable...) My HP had a 7-pin PWRCMD plug with only three of the pins in use; green black and grey on the 1st, 3rd, and 4th pins. I assumed that green was pwr on, black was gnd, and grey was pwr good. I hotwired from the ATX motherboard plug on the PSU to connect the PSU pwr on, PSU gnd, and PWRCMD gnd together, then I connected pwr good from the PSU to the pwr good from PWRCMD (just like in the video). I didn't use a switch at all. I just wired those pins to each other, ran power to the two 4-pin 12V CPU connectors on the motherboard from one of the 8-pin PCIe spots on the new PSU, and it all works great! I just turn the PC on and off with the stock power button on the front. It seems to power all the way down and then all the way up again without issue. I do have an external power switch on the PSU if I want it, but so far it seems like I might not need it. I'm using a Corsair 750W SFX PSU. Thanks so much for the info in this video! Fingers crossed my system stays happy!

Thank you for the video! Please tell me, is it necessary to connect Power good and Ground to P2 motherboard to turn ON the motherboard? Maybe P2 can not be connected at all?

There's one piece missing which holds the cog wheel together and place firmly in barrel. It's a kind of washer or "plug" type that slides in middle "metal part" of the wheel. Also this thing is the one that need to take out first and the whole wheel part comes out. I've the opposite issue ie key won't rotate.

Note for anyone reading this. Standard ATX PSU dimensions do not fit inside all HP cases.

I am doing some designing for my own machine. I think we can solve the 12V standby by using a step-up converter to the ATX 5V output, and then connect it to the 4pin 12V pins with diodes just as a precaution to not let power get from the main 12V back to the standby circuits. We just have to increase the step-up V for the diode drop voltage, and make sure the converter and diodes are rated high enough to handle the current. I am also not sure why the psu was cycling when you connected the power-on wire directly to the motherboard. Was it doing the 5sec force-shutdown thing? Or was it releasing the pin from ground after a while?

I have the same problem with my Audi A3 8P, I will try I hope it's gonna work. Thanks

Hello, i want to try your method, can i email you to help me to setup on how ?

I'm planning to upgrade an HP office PC with a fully modular Small Form factor PSU do I need an adapter for those or will it work just fine?

Did this method will work with HP Elitedesk 800 G4 SFF? I planned to transfer whole motherboard from it's original SFF case to regular PC case, and then I wanna try replacing it's original 250W PSU with regular ATX PSU with larger wattage. I really don't have enough budget to build another PC from scratch😢 Oh and my original 250W PSU have 7 wires on them, different than yours in the video.

the power connector I have says p1, p2 and p3

I'm sort of in a jam with my HPZ 230 as the PSU died and I want to install a non HP ATX PSU but am told it will be a hassle because of the 18 pin power connection on the MB, and even though there are adapters available, there is something about the OE PSU requiring a higher 11v stand by voltage? then the 5v most non HP PSU's produce. Some say that after such a swap they must use the new ATX on/off switch instead of the computers original on/off button.Others said the swap didn't work as expected. So I'm trying to find info on my situation if anyone can help, thank you.

I get 3 red beeps and 4 short white with a black screen any solution? thanks

This is a gem video.

@fixandtech I get 3 red beeps and 4 short white with a black screen. Any help would be appreciated

Is there any difference between 12v stand-by and regular 12v when on in terms of signal? Thanks a lot for this tutorial btw. I was thinking of doing this but I wasn't keen on being the first guinea pig to try.

Hi, if you turn on the psu switch which will supply 12v while the pc is off, it won't damage the system? Or the motherboard draws only whenever it's needed?

I had just attempted this on my HP Envy desktop with the same exact PSU, and I could not thank you enough for testing/documenting this! Instead of mounting a switch to the front of the case, I opted to bridge the power on and ground directly, which hasn't left any issues. Also, did you end up having to add more fans to the case? Still, couldn't thank you enough!

Where can I contact you I need some help

hey

Hi. thanks for the infos you gave! Worked perfect for me. I changed a little bit and added a Relais on the 5V ATX Standby line to do the power good signal (grey cable at the ATX connector). So I do not need the second switch.

I was looking for these and couldn't find any help online and there are no adapters or custom wires for 7+4+4 pin conf. Thank you. Just wondering, is your method better than just using a second PSU for the GPU using add2psu board?

Have you found any way to get the standby to work without needing to use any physical switches or is the "ground" to "power on" cable still the only solution?

thanks man! Got same problem on 2003 Seat leon. gonna try to fix it
