Question Using a standard ATX PSU with HP Z420 and Z440 motherboards ?

[Fantastical]

Hello
I want to know is it okay to use adapters mentioned below to power up Z420/440 MB with standard ATX PSU ?


first HP Z420 motherboard
I Saw few 24 pin to 18 pin adapter that lets u use standard ATX psu on this motherboard, but another power input is 8 pin and in that can I use standard ATX 8 PIN connector or need some adapter for this too?
this is the adapter https://www.ebay.com/itm/162499760677

2
this is the adapter for Z440 https://www.ebay.com/itm/256261634866
for this motherboard there is two adapter, 1 for 24 to 18 and another 8 to 12, the question is just if it is ok to use those adapters and use this HP MB with standard ATX PSU


And is there anything else special about those motherboard except PSU ? it is not applies to Power Supply section but i will ask it here as the thread is already open,
in this motherboard can i use standard GTX/RTX video card or need something another like quadro or firepro...
i just never had any touch with server/workstation items and all kind of info would be good.
Thanks.

It's the 8pin EPS, you should be good to go. The only thing you need as an adapter is the 24pin to 18pin adapter.

HP Z420 Base Model Workstation PSU

Hi The PSU has failed on the WS and it is no longer supplied by HP and it does not appear to be a standard ATX PSU - all the wire on the main m/b connector are black. The original PSU has the following- DPS 600 UB Spare p/n 632911-001 Can I use a standard PSU as a replacement? Thanks

standard ATX PSU
what is the make and model of this standard ATX PSU you keep referring to?

Just to be clear, which motherboard are you dealing with? A Z440 or a Z420?

Welcome to the forums, newcomer!

Thank you.

So as I understood it is fine for both option to use Standard ATX PSU.

Currently I don't have any.
But I was thinking about Z420 as it only need 1 adapter but if it is all fine I will go with Z440, as I did search ebay Z420 are ddr3 and Z440 ddr4

Power Supply usually I`m using DEEPCOOL, for that build depending on which video card I put in it i will go with
PF600 https://global.deepcool.com/product...lyunits/2021/15138.shtml?status=authorization
or
PF700 https://global.deepcool.com/product...lyunits/2021/15136.shtml?status=authorization

You might want to reconsider buying a refurbished motherboard for a platform that's already EoL(End of Life).

Poor GPU.

combos are cheap

Poor GPU.

why so? 🙁
I had Deepcool DN550 PSU https://www.deepcool.com/products/PowerSupplyUnits/powersupplyunits/2021/11937.shtml
in old PC for more then 2 years with AMD Radeon R9 280x and it was all fine, no problem with video card or psu all was running fine, i was playing games too

"Not being dead" doesn't mean it's running fine. Drunk drivers that make it home safely weren't driving well.

We're talking very cheap group-regulated, double-forward PSUs with mediocre capacitors and so cheaply made they couldn't even bother to give it a full input range. These are bad PSUs and using them with power-hungry GPUs is paying roulette.

We see a ton of cheap PSU disasters here and I can unequivocally say that cheap PSUs are one of the most expensive parts in a PC.

So If Build requires lets say 500w power and I will use 700w psu will not be it fine in that case?
as you mentioned those cant give enough power, that means 500w psu cant handle 500w pc but 700w?
and I told i was using that more then 2 years and that isn't short period, I`m not arguing that it will do better then some high-end psu ( i don't even know which are so good), but If it was all fine in heavy load`s during 2 year, doesn't it means it is good cheap option?

It's not just the wattage number. That's like comparing cars solely by cargo capacity. Yes, you need *enough* cargo capacity for the things you need to transport, but there's a whole lot of other stuff that goes into the quality of a PSU: voltage regulation, ripple mitigation, capacitor quality, topology, protections, efficiency, and on and on.

ok then what is the option? cooler master? thermaltake? or some other brand? (not some extremely high cost like Ferrari )

Depends where you are and what GPUs you're looking at. You don't have to spend an insane amount of money, but we're talking bottomed basement here. The most-used tier list doesn't have this PSU as "Tier E - Avoid" without good reasons.

Generally speaking, the rule of thumb is Tier A for high-end GPUs, Tier B or higher for non high-end GPUs that require supplementary power, Tier C or higher for GPUs that don't require supplementary power, Tier D for grandma's email-and-solitaire rig. Lower than that is for testing water cooling components or fans or a recycling center so they're not e-waste.

I`m in Georgia (not state, but country in EU), and GPU is GTX 980
this will be tier A or B?
and as we move beyond of topic already i will ask what is this ?
multi/single-rail switchable?

No need to worry about multi/single rail, and in any case, the true multirail PSUs will be out of the price conversation.

I'd personally go Tier A, because like old German cars you get cheaply, they're still expensive to maintain. But you can probably get away with a Tier B.

understood, I`ll take a look on them and compare prices and figure out a bit more about them.
Thanks for advice 👍
