Question Anyone have any experience with HDPLEX 500W HiFi DC-ATX? What is the optimal input for that power supply?

[reaper89971]

I just purchased this power supply and do not have it yet. The HDPLEX 500W HiFi DC-ATX.
https://hdplex.com/hdplex-500w-hi-fi-dc-atx-power-supply-12v-48v-wide-range-voltage-input.html

It has a really wide range of input voltage 12v-48v but does not mention amperage,

Wondering what voltage and amperage would make it run optimally?




I need the power supply to give me at least 400 watts on the 12v rail to power my system comfortably or at least that is what is recommended for my system kinda i can't get an exact power supply calculator to tell me how much power i need.

The system i intend on building
Sleeper PC:
Case number 1 problem: Fat Playstation 2 SCPH 30000
Motherboard Asrock mini industrial IMB-1220-D

(10th gen this board is the newest gen board with the power plug on the left side and that is really important when it comes to fitment also its a lga 1200, the lga 1700 is alot bigger harder to fit in there the heat sink i mean)

CPU intel i9-10900 65watt tdp but goes up to 224 watts when boosted
Graphics card the PNY Nvidia T1000 8gb gddr6 single slot supposidly goes up to 50watts maximum current draw
Ram Vengence DDR4 2933 mhz ram 32gb 2 modules
Hard drive Samsung 870evo 4tb
Power supply: not sure yet
Cooling: still figuring that out. I might do several 35mm fans that will have there own power
Heat sink: ID cooling 30mm

The second problem is Power I found a pico power supply 600 watts but it is from china and is unbranded witch means it could be great or it could be horrible Unbranded is a little risky in my opinion. Or i go with the above power supply witch has a brand and is only 31mm high and should fit in the case.

Are you trying to use this for a camper/car/boat type application?

I may not be understanding the assignment, but it would seem to me to consider your build from a traditional point of view insofar as even using a regular 120VAC power supply in it. Run calculations out of a wall socket with a tool to read draw and then select a DC to AC converter of the proper output.
Most often, the type you are wanting will be drawing directly from the battery itself so Amp draw on that side won't be any concern at all. Typically these will come with a 15A fuse link on the output side, so pretty much like a standard wall plug in a home (United States).

edit- and just as an aside, if this is running directly from a battery be sure to install a proper sized fusible link inline in case of a short or whatnot

I was going to run it using some type of power supply not a battery.
Im going to build a computer inside of a playstation 2 case and was going to cram that power supply into the case.

I just don't know what amperage would make the power supply run optimally? I know the voltage input but not the amperage

Ok, so what is being used to supply the power to the power supply?

15amp 110v from my wall outlet in the united states

I found a medical AC DC adapter 24v 250 watt by Delta Electronics
MEA-250A24C H-A 24v 10.42amp
Type the name of the power supply above into the website below and then you can download the Data Sheet and Manual
https://www.deltapsu.com/en/product-documents

The MEA-250A24C uses a 6 pin connector but the HDPLEX 500W HiFi DC-ATX has a 8 pin DC input Connector.

Can i use a regular ATX 6pin to 8 pin connector? Or would the current and voltage be 2 strong for a regular adapter cable?

Is there a heavy duty 6pin to 8 pin Connector for medical purposes?

I got the power supply for 25$ when it is normally 240$ so i found a deal on it that is why i wanted to use it. Will this Medical Power supply work?

The largest reason to be concerned about the MEA adapter is not the plug or voltage. It is only rated for 250 watts. That means even though you hook it to a 500 watt power supply you still can only use 250 watts and that assumes you can actually get the 250 watts in the first place.

So power is kinda simple when you talk dc. watts is voltage x current. So 24 volts at 21 amps and 12 volts at 42 amps are both around 500 watts. The key difference is wire size is based on amps. You need smaller wires for 24 volts or you can run with less larger wires than 12 volts. You would really only need a 2 pin connector if the wires were large enough. They use 8 because it is easier to use more small wires than fewer large ones.

This brings me back to my first question what voltage and amperage would make that power supply run optimally?

They don't list amperage on there website but give you a wide range of input voltage witch suggest you have to do your own math on power. They don't list a input current max even. Unless i am mistaken.

They reccomend a ACDC adapter that is 19.5v at 330 watts Dell model la330pm160, I will probably just use that to be safe assuming that will give me enough power to get that power supply running optimally.

Problem is there are a bunch of generic and unbranded and fakes of that power supply. Hard to find Dell and it is expensive.

If it does not run optimally i will have problems. I really don't want to short my expensive computer parts.

Very hard to say on what is "optimal". Since the vast majority of the power you are actually going to use is 12 volts you would think that would be the best input. Modern power has gotten much better at converting from one voltage to another. Used to be a lot of that extra voltage would be lost to heat. Likely there is still some but how much is hard to say.

Laptop power I am unsure why they run the voltages they do. The main motherboard mostly runs on 12 volts. I suspect it might be the display that like higher voltages.

Just be aware 330 watts is still less than 500. If the computer where to attempt to pull more than 330 the power supply would have no issue but it could damage the ac adapter. Just be very sure you are not pulling more than 330 watts.

Part of the difficulty is a lot of computer things, video cards in particular, can spike their power draw. A 4090 for example does not draw 450 watts constantly but it will spike to value and higher on models that are overclocked.

I did some searching around and then went to the mean well website and found 2 power supplies that would be able to power the HDPLEX 500W HiFi DC-ATX up to 500 watts at whatever voltage it would accept.

EPP-500

LOP-500

I called the maker of the power supply and you get nothing but an answering machine. I left a message not sure were they are located. With the hurricane Milton and Halene maybe they are evacuated. Or maybe they will return my call.

With such a wide voltage range there has to be one that runs better than others. I wouldn't want to give it the max or the least so i was going to just go in the middle at 27volts and hope for the best.

With LOP-500-27 it has a peak wattage of 750 watts not sure if that is a problem. So if the power supply peaks for some reason it will blow the other board up.

Why would a power supply peak? I need the power supply to never peak out for any reason.

 

[bill001g]

...so I started a response and I will call the device like lop-500 "power adapter" and the hdplex device "power supply" even though both are technically power supplies.

That is kinda tricky. It would be better to say the power adapter can PROVIDE 750 watts peak power. It does not randomly just put out power it. It is more the device connected to it that will "request?/draw" the watts. Now I guess if computer somehow requests the power supply give it 750 watts and the power supply then got that much power from the adapter something is going to likely be blown out. That should never happen. Your pc does not seem to need anywhere even close to the 500 watts the power supply can handle and that is even less than the 750 the adapter can provide.

It should be fine having too much capacity is always better than having not enough.

I have not looked at the pricing but it almost seems you could get a physically small computer power supply and put it in a external box and accomplish the same thing. Real pc power supplies have all kinds of extra circuits in them to protect the power supply and the computer from damage due to shorts and temporary excessive power draws. If for example you had a very high power video card connected to low watt power supply if the video card would spike the power requirement the protection circuits in the power supply will shut the power supply and the computer down before any damage occurs. Very cheap power supplies have simple fuses but most more main line computer power supplies reset themselves if you unplug them. This is part of the reason a computer supply is rather expensive compared to the type of devices you are looking at.
