Do people have any knowledge about using this power supply, and what should be the best input setting?
I just bought this power supply but haven’t received it yet:
HDPLEX 500W HiFi DC-ATX
.
https://hdplex.com/hdplex-500w-hi-fi-dc-...input.html
It offers a broad input voltage range from 12v to 48v, but it doesn’t specify the amperage. I’m curious about the ideal voltage and current settings for optimal performance.
I need this power supply to deliver at least 400 watts on the 12v rail to comfortably run my system. Since I can’t find an exact power calculator, I’m trying to estimate what’s needed.
The project I plan to build includes:
Sleeper PC:
Case number 1 issue:
Fat Playstation 2 SCPH 30000
Motherboard Asrock mini industrial IMB-1220-D
(10th gen – this board has the power plug on the left side, which is crucial for fitting. It’s also an LGA 1200, and the LGA 1700 is much larger and harder to fit, especially with the heat sink.)
CPU intel i9-10900 – 65W TDP, but up to 224W under boost.
Graphics card: PNY Nvidia T1000 8GB GDDR6, single slot, max draw around 50W.
RAM: Vengeance DDR4 2933 MHz, 32GB, two modules.
Hard drive: Samsung 870Evo 4TB.
Power supply: still uncertain.
Cooling: I’m still deciding. I might use several 35mm fans that will require their own power.
Heat sink: ID cooling, 30mm size.
The second concern is a Pico power supply rated at 600W, but it’s from China and unbranded – it could be excellent or problematic. Unbranded models are a bit risky in my view. Alternatively, I could stick with the branded one, which is only 31mm tall and should fit in the case.
Is this intended for a camper/car/boat project?
I might not fully grasp the requirements, but it seems reasonable to evaluate your design from a conventional perspective, especially when using a standard 120VAC power source. Perform calculations using a wall socket tool to determine the draw, then choose an appropriate DC to AC converter.
More commonly, these systems will draw directly from the battery, so the current drawn from that side shouldn’t be an issue. Usually they include a 15A fuse on the output side, similar to a typical household wall outlet in the U.S.
Also, just a note—if power is coming straight from the battery, make sure to add a correctly sized fusible link for safety.
I planned to use a different kind of power source instead of a battery.
I intend to construct a computer inside a PlayStation 2 enclosure and fit the power supply into it.
I’m unsure about the correct amperage needed for optimal performance; I only have the voltage information.
I located a medical AC DC adapter 24v 250 watt by Delta Electronics.
MEA-250A24C features a 6 pin connector whereas the HDPLEX 500W HiFi DC-ATX requires an 8 pin DC input connector.
Can I switch to a standard ATX 6pin to 8pin connector? Would the current and voltage be sufficient for a regular adapter cable?
Is there a robust 6pin to 8pin connector suitable for medical applications?
I purchased this power supply for 25 dollars, which is typically 240 dollars; I discovered a discount and wanted to take advantage of it. Will this medical power supply function correctly?
The main concern about the MEA adapter isn't the plug or voltage, but its power rating of 250 watts. Even with a 500 watt supply, you're limited to 250 watts, which depends on whether you can actually obtain that amount. Power dynamics become clearer when considering direct current: watts equal voltage multiplied by current. For example, 24 volts at 21 amps or 12 volts at 42 amps both approximate 500 watts. The main factor is wire size, which relates to the current capacity. You'll need thinner wires for 24 volts or you can use smaller wires than those for 12 volts. A two-pin connector would suffice if the wires are adequately sized. They choose eight pins because it simplifies wiring with more individual wires rather than fewer larger ones.
Thank you for your reply. This reminds me of my initial inquiry about the optimal voltage and amperage for that power supply. They don't provide amperage details or a clear input current limit, which makes it necessary to calculate based on your own calculations. If I'm not wrong. They suggest using an ACDC adapter rated at 19.5v for the Dell model la330pm160, and I think that would be a safe choice to ensure proper performance. The main concern is dealing with many generic or fake versions, which are hard to find and can be costly. If it doesn't work well, I'll face issues and might have to risk damaging my expensive components.
It's tough to determine what's truly optimal. Given that most of the power you'll actually use is 12 volts, that seems like a reasonable starting point. Over time, power systems have improved in their ability to change voltage levels efficiently. Previously, much of the extra voltage would dissipate as heat, but the exact amount remains uncertain.
I'm not sure why laptops operate at these specific voltages. The main motherboard typically runs on 12 volts, which might explain why displays prefer higher voltages. Just keep in mind that exceeding 330 watts could strain the power supply, though it shouldn't damage the adapter if you're careful.
The challenge lies in the many components of a computer, especially video cards, which can significantly increase power consumption. For instance, a 4090 graphics card doesn't maintain a steady 450 watts but can surge to much higher levels when overclocked.
You searched online and found two power supplies suitable for the HDPLEX 500W HiFi DC-ATX. You considered options like EPP-500 and LOP-500, but when contacting the manufacturer you received no response. You’re concerned about the wide voltage range and want to ensure the supply handles it well without risking damage.
