    Snake oil. If you have line / supply noise issues, get a line conditioner and/or a surge protector. No amount of replacement power cabling will enhance your machine otherwise. If you location has really dodgy power a line conditioner is more beneficial. It can alleviate most noise and voltage fluctuations. More recent tech has the basic functionality built into the power supplies.

    The primary benefit of a fancy/expensive surge protector isn't the actual protection, it's the warranty if something goes wrong.

    Some examples of line conditioners can be found here

    no, usd 56 is way too cheap for a power cord :deep_facepalm:

    nostalgia, a cable is never too thick! its wastefulness, no other harm done.
    a cable thats too thin is a danger, it could heat up, melt the insulation and so on. when in doubt, bigger is better!

    your new cable has an outer diameter of 17 mm, i could imagine some bent strains while routing :)

    Yes, it's possible and no, it won't damage your computer. It only damages your wallet because it's useless.

    @Nostalgia_Rocks

    Yes.

    This does not apply for; 1. AWG is just thickness; 2. the current is determined by your home breaker and has nothing to do with the cable you are using.

    If your issue is with interference, you'll do far better with a Double Conversion, or a line interactive UPS.

    Good luck.

    What you should ask yourself @Nostalgia_Rocks , is what makes an expensive cable worth the money. I can think of a good number of reasons why buy an expensive cable but these DO NOT include power cables. So as anyone else answered here, find some better way to spend your money mate. If you can't, i am all willing to help you. :)
    Cheers

    A few reference sources to help you understand and, make your own determination.

    Computer power cord AWG: Why it matters
    https://dfarq.homeip.net/computer-power-cord-awg-why-it-matters/

    Anything that chokes proper movement of a resource is not good (audio, electricity, water, gas, etc...).
    Using a quality cable that meets or exceeds maximum wattage & current draw with a well designed power supply will not hurt anything. You don't need to spend loads of money to achieve this.

    220V, 230V & 240V PSUs will require a well made cable rated for the maximum draw.

    Theoretically yes, since all cables that fit into the inlet should comply to an IEC standard and are rated for 10 A (equals up to 2500 W). I don't know if you could find some "fake" cables on Amazon, eBay, etc., but there shouldn't be a problem when you check the specs in the description (and later on the cable).

    modern psus are auto-voltage, usable for anything from 100-240 volts. power equals voltage times current, therefore for the same power, less voltage requires more current. the required power will be dictated from the specific computer. a psu on 110 volts means double the current, than on 240 volts! IF you care about the cable's "draw", 110 volts driven psus need the better cable, current-wise!

    Usually recommendations:
    • 18 AWG - 10 amps@125V
    • 16 AWG - 13 amps@125V
    • 14 AWG - 15 amps@250V (also good for 110-120v PSU in system with high GPU, PCIe & CPU draw)

    A 10AWG 2 conductor +G wire can carry 25Amperes at up to 600V, 30degrees C & 15Meters.

    A 800W PSU will draw under 7Amperes @110V and under 4 at 220V.

    It's a bit overkill but it can't hurt anything as current is drawn and not pushed.

    If you have a power-surge in the line it doesn't matter what wire you are using as RMS and thermal load are more important to a wire than a spike in voltage, either wire will be more than adequate to carry a harmful voltage spike.

    Remember that as voltage increases, resistance decreases & potential increases that is why 800W at 220V only needs 3.7Amperes at 15M, while the lower voltage will need almost double the amperes to carry the same Joules/Sec (Watt.)

    If you want to think of your computer as car or a horse [ 1 Watt (J/s)= 1 N*m/s= 1Kg*m^2/s^3 = 0.001341022 Horsepower. ]

    Enough useless information.

    A good quality surge protector or even a better properly wired panel and a switching UPS between the house's electrical circuit and your computer will protect you against surges, the kind of wire you use will make no difference.
