That’s great because there will be some strong low profile GPUs coming both from nVidia and AMD (Hopefully with reasonable price tags). Another fact is that despite there are great PSUs, they are either from USA or Asia which makes European customers deal with shipping costs, time and customs taxes. Would be great to have an alternative to HDplex in Europe If you would consider to sell them through a European reseller or yourself.

As promised, I tested the j-hack plugin-160 again to make sure the unit was not defect. This time I tested all rails combined at 20°C ambient (last time ambient was 36°C, so output power was derated). Below you can see the results at what wattage the board shuts down.

Don't get me wrong here, from my point of view the plugin-160 is a great choice for a 160W build and has some overhead but according to my tests I respectfully doubt that it can handle 16A output on the 12V rail.

I'm not sure how that proves that the unit "isn't defective." Just because it's not a critical failure, doesn't mean it's not defective. This post really leaves a bad taste in my mouth as if I'm designing products that don't meet the specs I put out.

Here is my set up: 1050 ti, Ryzen 1600, Asrock
Software: Prime 95 and Unigine Valley running
Ambient, 24 C.

Guestimate 12V rail consumption: 11.5A.

SOC+CPU consumption: 75-80W (all 12V rail). You can see it avg 80W in third picture.
GPU: 70W (mostly all 12V)


I'll refrain from further posting in this thread, as it'll just cause a distraction and takes away from my credibility as if I'm attacking third party testers.

Where did I mention that your product doesn't meet the specs you put out? You are selling it as 160W and it clearly meets these specs. I even gave a recommendation for your product and didn't leave a bad word.

Don't get me wrong here, from my point of view the plugin-160 is a great choice for a 160W build and has some overhead
What I said was that I couldn't get 16A from the 12V rail during my tests. And that is actually totally in line with some external reviews of the pico-box 200 plugin which is a good 200W board and gives you max 12A on the 12V rail. Even the HDPlex 200 only states 15A cont. on the 12V rail.

Again, for a 160W plugin its a great product and since you are not officially advertising it as 200W or 300W I can clearly recommend it.

I guess my issue was that yours topped out at 8.5A on the 12V rail.

Compared to my setup, that would be impossible if your the CPU/SOC is 80W and you have a 1050 ti. A regular computer runs very little on the 5/3.3V, pretty much its all on the 12V rail.

Taken at face value, your test results means it doesn't meet the specs, as the computer uses mostly 12V.

What likely is happening is one of the mosfet is not being driven. It has been a long time since I worked on the project but I believe it uses two mosfets for the 12v. All J-HACK Plugin units are rated off the 12v rail, as it is the only rail that matters.

Note, picobox is a different, but similar design. Picobox uses p channel mosfet. Plugin series uses n-channels.

Edit: thank you for your recommendation, but I wanted it to be clear that this is not the norm.

We could easily find out if you or someone has a >125W CPU and 75W GPU powered by your 160 plugin board. If that setup would work under full load testing we have proven that my test sample is indeed defect.

Again, I don't want to talk your product bad or something. I'm just trying to find options for people who need a >300W plugin solution for their build.

Edit: no problem. We both just want to provide the community with good products for their projects. I see no competition here and I'm also open to work on something together to achieve better MOQs and prices for the customers.

Pls, black PCB and more better heatsink (also black), notebook power in (like HDPLEX 200w). And I will insta get it.

Then I would recommend the G-unique Archdemon for you. It's black and you can ask him to customize everything for you.
I'm trying to make only one standard version and hopefully still can get the price down by that.

Talking about price/cost and personal preferences I would like to come back to the actual project:
  • Do you prefer to have sleeved cables?
  • How long shall the different cables be?
  • For the DC input cables, would you prefer cable lugs or some other connectors?

I had one more idea concerning the DC input to power the board. What do you think?

Option A: Screw terminals on the PCB to connect your AC-DC power source? (I would provide loose cables and cable lugs for you so you can modify the length DIY)



Option B: Pre-configured with cable lugs. Cable length 300mm.

Option B, but keep the cable lugs separate so we can get our exact length. Also white and black cables instead of that red and black!

Unfortunately I didn't find any good white cables with 8 or 16 AWG yet. But you could just put a sleeve on. I can also include some shrink tubes and I have white silicone sleeves available.

  • 350mm DC-IN with cable lugs (other length upon request)
  • Output: up to 360W on the 12V rail, up to 100W for combined 5V, 3.3V, SB, etc...
  • Input: 12V DC, max. 40A (480W)

Recommended AC-DC power supplies:
  • internal: MEANWELL RPS or EPP-400 // RPS or EPP-500 (12V output)
  • external: MEANWELL HVG(C) Series (12V output) // DELL Power Brick with 12V output

Example: 105W CPU + 175W GPU --> minimum recommended AC-DC power supply: 350W @ 12V


"Founders Edition" price
to Europe: EUR 55,-
to the U.S.: USD 60,-

Lead time depends on pre-orders. I'll start shipping with 10 pre orders. If you are interested, just send me a message.

@ oOflyeyesOo: I've finished the custom version for your MID1 build.

For the normal version I'll probably go with 4x2.5mm DC-IN cables. The 2x8AWG are too thick and stiff so it might not fit in some smaller cases with less space around the mobo.

so... I was thinking to make the DC-input modular. This would allow to offer different pre-configured cable length ...but this would block headers on some motherboards... 👍 👎 ?



Does someone here have experience with the G-Unique Archdemon and HDplex 200? Are you still able to use all the connectors on your motherboard, e.g. SATA and front USB header?

On some pictures I found, it looks these plug-in PSUs are also blocking access to some of the MOBO headers, either on the left or right side?

May be better off having the connectors on a short pigtail instead? I dunno, I don't think that part needs to be modular since you have to use the power to use the board. SATA maybe could be modular

Yeah, I'll probably have to go with pigtail for better compatibility. The main reason I wanted to put the connectors on the pcb is that these are easier to solder compared to the thick cables you'll need for 35A. Maybe I'll go with solid coper wires and then the connectors.

Yes, Sata is modular. CPU and PCIe soldered.
