    As the topic
    Is the Akyga model: AK-B1-500 power supply good ??

    Added after 3 [minutes]:

    I am asking because I was going to undress it for a part.

    Added after 6 [minutes]:

    I currently have Logic 400Atx

    Both power supplies are the "bottom". They cannot be included in the recommended power supplies.

    There is nothing to brag about, a blacklisted power supply.
    The first one, didn't you mistake the name, maybe it's AKYGA? Also from this list.

    Logic has a lot of good reviews, I have been using it for a week, pc has been started almost 24/7 and works smoothly and quietly well. I don't know why he was on black and who put it there.

    I don't know, maybe it's a better product than "logic" :P
    As for me, both of these power supplies are suitable for parts.
    But if you want, use it while it works. I will not deny. But things can happen during a breakdown.

    I don't know if it's because of it but I used to be a skayga (whom I am a little afraid to put in) probably set fire to my hard drive "literally burned"

    I had a Logic power supply which spit on the + 12V output over 13V.

    The quality of these power supplies is very low.
    Tacky capacitors, poor stabilization, low efficiency.
    There are many disadvantages.

    Multimeter measurement alone should be sufficient.
    A friend will remove such a "super power supply" from the computer, launch a jumper (green wire in the ATX plug shorted to ground) and then connect a few halogen / car bulbs to the + 12V line.
    Your friend will see how dumb these power supplies are.
    It is possible that you will have to weigh the + 3.3V and + 5V lines because in these power supplies the stabilization consists in measuring the voltages of these lines. Currently, almost all hardware in the computer uses + 12V, + 3.3V / 5V was used intensively somewhere in the early 2000s and earlier. This stabilization method causes that the voltage on the most important + 12V line will sit firmly in most situations.

    The picture clearly shows how these power supplies are made.

    In the first post a colleague wrote that he is going to take it apart.
    This is the best application for this power supply.

    A colleague will have high voltage transistors, a handful of low and high power diodes, integrated circuits (operational amplifiers are added), coils and transformers, and other elements useful in building your own systems.

    Luckily, your colleague will have enough elements to build a simple workshop (linear) power supply.

    Where are you written " skayga "??
    AK-B1-500 is Akyga , which is one of the worst shacks on the power supply blacklist.

Topic summary

✨ The discussion centers around the Akyga AK-B1-500 power supply, with users expressing skepticism about its quality and performance. Many participants categorize both the Akyga AK-B1-500 and the Logic 400ATX power supplies as subpar, often referring to them as "blacklisted" due to their low reliability and potential hazards. Concerns include poor voltage stabilization, low efficiency, and the risk of damaging components, as one user recounted a negative experience with a previous Akyga unit that allegedly caused a hard drive failure. Despite some users defending the Logic model for its quiet operation, the consensus leans towards caution, suggesting that these power supplies are more suitable for disassembly and repurposing rather than reliable use in a computer system.

FAQ

TL;DR: Budget PSUs like Akyga AK-B1-500/Logic can push +12V to 13V; "The quality of these power supplies is very low." Use only for parts or testing. [Elektroda, pawelr98, post #17066567]

Why it matters: This helps PC builders decide whether to trust, test, or replace budget PSUs to avoid hardware damage.

Quick Facts

Is the Akyga AK-B1-500 a good power supply for a PC?

No. Forum experts class Akyga AK-B1-500 among blacklisted, bottom-tier units. It lacks reliable voltage regulation and protective robustness. Using it risks instability and component damage under load. "One of the worst shacks on the power supply blacklist." [Elektroda, Robert B, post #17068754]

Is "Skayga" the same as Akyga AK-B1-500?

Yes. The AK-B1-500 designation belongs to Akyga. The spelling “Skayga” in posts is a mistake. Confirm the label on the nameplate before any testing or use. [Elektroda, Robert B, post #17068754]

Can a cheap PSU like Akyga or Logic damage my components?

Yes. A user reported an Akyga burning a hard drive. Overvoltage and poor regulation can destroy storage and motherboards. Even short use can hide serious faults. Replace the unit promptly to protect data. [Elektroda, Drodzia, post #17066536]

Why are Logic and Akyga considered bottom tier?

Because of observed overvoltage, weak regulation, low efficiency, and cheap capacitors. "The quality of these power supplies is very low." These traits show poor design and inadequate safeguards. Replace such units rather than risk failure. [Elektroda, pawelr98, post #17066567]

Does running 24/7 for a week mean it’s safe?

No. Quiet operation does not prove compliance. Measurements showed +12V exceeding 13V on a Logic unit. That exceeds ATX limits and risks damage. Replace rather than trust short‑term uptime. [Elektroda, pawelr98, post #17066567]

How do I test a budget PSU safely with a multimeter and bulbs?

Follow this quick bench test at your own risk.
  1. Unplug the PSU and short the green ATX wire to ground.
  2. Load the +12V rail with halogen or car bulbs.
  3. Measure +12V; if needed, add loads on +3.3V and +5V to stabilize group‑regulated designs. [Elektroda, pawelr98, post #17066567]

My +12V reads 13.0V. Is that out of spec?

Yes. ATX12V allows ±5% on +12V, or 11.40–12.60V. A 13.0V reading is out of spec. Stop using that PSU and replace it. [ATX12V Power Supply Design Guide]

What is group regulation and why can it be risky in modern PCs?

Group‑regulated PSUs sense 3.3V and 5V for control. Modern PCs load mainly the 12V rail. The result is 12V can sag or overshoot under crossload. That behavior risks GPU and CPU stability. [Elektroda, pawelr98, post #17066567]

Should I keep using Logic 400ATX or Akyga until it dies?

Avoid that plan. You can run it, but failures may be destructive. "Things can happen during a breakdown." Back up data and schedule a replacement immediately. [Elektroda, sylweksylwina, post #17066528]

Is the AK-B1-500 good for parts or DIY projects?

Yes. Salvage high‑voltage transistors, diodes, coils, transformers, and ICs. These parts can build a simple linear bench power supply. The PSU itself should not power valuable PCs. [Elektroda, pawelr98, post #17068528]

What should I look for in a safe replacement PSU?

Choose a unit that meets the ATX12V design guide. Ensure +12V stays within 11.40–12.60V under realistic load. Verify regulation with a multimeter or trusted reviews. [ATX12V Power Supply Design Guide]

Do I need to load the 3.3V and 5V rails when testing?

Often, yes. Group‑regulated units stabilize by sensing +3.3V and +5V rails. Without load there, +12V can drift. Add modest loads on those rails during testing to observe real behavior. [Elektroda, pawelr98, post #17066567]

How can I check if Akyga AK-B1-500 is blacklisted?

Check the community blacklist thread referenced in the discussion. Experts point to blacklisted brands and models there. Use it to avoid risky PSUs. [Elektroda, sylweksylwina, post #17066566]
