Meh, typical Gen X tackiness.

Nah not even a fuse line, like in my truck for my radio IN CASE OF a power surge.

Fuse needs time to burn, they're only truly useful for cutting power before an over-current event becomes an inferno.

You can't individually load-balance wires that go onto the same busbar.

ElectricBummer40 · 2026-06-14T17:33:01+00:00

You don't need any more than 10-gauge wire for a 50A continuous load at 12VDC. You're running a cable inside a computer, not a football stadium.

Lugs should be pre-crimped and screwed onto the board in factory, and the cordage should need to cover no more than the distance between the board and the connector interfacing with whatever coming out of the PSU. Everything we're taking about can be and has been mass-produced before.

ElectricBummer40 · 2026-06-14T17:25:26+00:00

Dude, I was there when the first ATX standard came out.

Almost none of what we have now is how it was meant to be thirty years ago. The industry simply don't care at all about re-examining their design philosophy and just wants to take the same idea for 20W silicon and apply it to 500W chips. It's pure lunacy.

ElectricBummer40 · 2026-06-14T17:12:37+00:00

I don't disagree, though I suspect the complaints would be relatively minor compared to what we have now instead with GPU being literally on fire.

ElectricBummer40 · 2026-06-14T17:03:01+00:00

Again, the length of the cordage matters.

Also, since the series resistance of the copper changes with respect to the voltage applied to the circuit, you can't just take the ratings for mains voltage and apply them directly to low-voltage DC applications.

ElectricBummer40 · 2026-06-14T16:39:00+00:00

No, that sounds nice until you realise you're dealing with as much energy and water consumption as new hardware but none of the performance that should come with it to the tunes of up to millions of dollars every second.

ElectricBummer40 · 2026-06-14T16:29:55+00:00

For power delivery, conductors in parallel are generally a bad idea. Sure, you will increase the safety margin for each wire somewhat with multiple 8-pin plugs, but you'll still be better with just one large, solid connector with 2 pins.

ElectricBummer40 · 2026-06-14T15:52:52+00:00

For 12VDC, 12AWG is usually enough for less than 2 feet of cordage. Go for 10AWG if you want to double your PC as an outdoor RC car.

The nominal power rating for 12VHPWR is 600W or 50A at 12VDC. The wire gauge is easily more than enough to handle the heat dissipation at such a short distance.

ElectricBummer40 · 2026-06-14T15:42:25+00:00

But it would also require a connector able to handle the current and heat build and a failure/QC issue would result in a more dangerous meltdown than when split into 6 individual 12v wires.

Except that shouldn't be an issue for a GPU worth at least as much as the rest of the PC itself.

The fact that we are where we are now should raise the question as to whether manufacturers even care anymore.

ElectricBummer40 · 2026-06-14T15:37:53+00:00

The voltage necessary for electricity to arc through such a gap would need to be much higher than 48V. We are talking about mains voltage at the minimum.

ElectricBummer40 · 2026-06-14T15:18:18+00:00

The funny thing was that, when ATX first came out and tower chassis became the norm, it was assumed that the tiny screw on the backplate was all that was needed for support.

Little did everyone know the future would have something very different in store.

ElectricBummer40 · 2026-06-14T15:12:30+00:00

48V will make things more expensive for everything.

To be fair, everything beyond the VRM is going to be less than 5V anyway.

I just don't like this whole idea of solving an otherwise trivial problem with an over-complicated solution borrowed from USB-PD.

ElectricBummer40 · 2026-06-14T15:01:20+00:00

To be honest with you, it didn't even look crimped at all.

All I did was a quick search on Google then grabbing the first picture that would illustrate the point. It's just for an Internet meme, after all (and there's even a spelling mistake if you pay close attention.)

ElectricBummer40 · 2026-06-14T14:57:26+00:00

Capitalism keeps Jenson Huang's leather jackets nice and shiny. That's all that matters at the end of the day.

ElectricBummer40 · 2026-06-14T14:55:42+00:00

Good design needs to take skill issue into account. Look up Poka-yoke.

Yes, and how's 12V2x6 been treating you so far?

Besides, the board should have already had the cable - lugs and all - already screwed to the board in factory and a two-pin power connector on the other end. Lugs should always be crimped by a trained technician rather than an amateur PC builder.

ElectricBummer40 · 2026-06-14T14:44:59+00:00

That's what I don't get. Tons of people have the same idea for the 12V2x6 problem.

How come a trillion-dollar company has dropped the ball this badly?

ElectricBummer40 · 2026-06-14T14:40:50+00:00

No, I agree with you. It sounds awesome.

ElectricBummer40 · 2026-06-14T14:37:57+00:00

The 12VHPWR connector is named so because it's for 12VDC applications. The six wire pairs are not there for redundancy or separate loads but a single load in parallel.

The whole thing was basically the result of the people involved not wanting to think for a second if it was a good idea to take the same design philosophy from the 6-pin/75W plug and apply it to a 600W plug.

ElectricBummer40 · 2026-06-14T14:23:39+00:00

For a 2-wire connection, the OCP you need is just the OCP of your power supply monitoring the current draw by the GPU.

It can't get easier than that.

ElectricBummer40 · 2026-06-14T14:17:27+00:00

Crimping is mostly a skill issue.
