content: what you think,should eu and amercika should start forcing manufacturers making all psu cables be universal?with this i mean that you can swap cables between any brand psu u own and not risking blowing pc up.it will be forced on all manufacturers,if someone refuses to do it,then their prodcuts are not allowed to sell in eu/usa stores.

content: You mean computer power supplies, yes?Pretty sure they are (mostly? completely?) standardized as it is.

content: Quote from: Analog Kid on January 20, 2025, 03:13:06 amI think he means the DC end of modular PSUs. As far as I know, there is no standard when it comes to the bit that connects to the PSU end. They are manufacturer-specific, and even in some cases, model specific.

content: My knowledge must be out of date.I previously had only seen standardized PC power-supply connectors (the DC end) and thought they were all like that.What happened to that? Theyshouldbe standardized, yes?

content: I suppose they strictly talk about laptops. In which case, although the standard 5.5mm barrel jack is not uncommon, many manufacturers have tended to have their own proprietary connector.This is becoming kind of a moot point as progressively all manufacturers are switching to USB-C for power/charge.

content: Quote from: Analog Kid on January 20, 2025, 05:34:09 amThe DC end that connects to devices like the mainboard, hard drives, etc... those are all standard. But the other end of that cable, for PSUs that are modular (i.e., not hard wired to the PSU) are different.

content: Ridiculous, if someone wants nice circular connectors with shielded cables or whatever for their graphics card, let them have itI always thought of this modhttp://www.vlf.it/noisesuppressor/PCnoisesuppressor.htmlAnd you have some whacky stuff, that might actually have a use for RF lolhttps://hdplex.com/hdplex-fanless-500w-atx-linear-power-supply-with-modular-atx-output.htmlI think its meant for audiphiles, but its none the less interesting

content: Quote from: Analog Kid on January 20, 2025, 05:34:09 amI think Halcyon means the "power-supply end of the DC cables". Modular ATX power supplies look like this:They are the same MOLEX mini fit as used for ATX22+4 connectors on motherboards, but not standardised. PSU makers strongly warn against using cables from other PSUs.

Miniscule, even, and i expect it to continue to shrink further.
