See the connector in the first pic? Well, that fucker is the main source of damage to working desktops. The problem is that it is located on the upper left part of the mobo, quite far from the other power connectors, meaning that with the usual placement of the psu in an atx case (both above and below the mobo) the cable will lightly but constantly tug the thing towards the right side. After a period of time that typically goes from 1 to 3 years, depending on factors like the weight of the cable and other material qualities, the connection will become loose. As the crappy second pic shows the connector is still making contact but with a significantly reduced area and as expected, this causes an increase in the resistance proportional to the decrease of said area. High end cpus are known to melt the connector when this happens but even the ones with the lowest power requirements are affected. The reason is that the system will compensate the increase in resistance by ramping up the voltage supplied, effectively getting all the downsides of a very heavy overclocking with none of the benefits. Stuff like a general increase in temperature of the system, sluggish performance, tripping the overvoltage protection on a stock cpu at idle and making the computer unbootable in a hard reset loop are common if the problem goes unchecked, because it worsens as the connector keeps getting looser with time.

This is a problem tied to the design of the connector itself and affects every system that makes use of it, regardless of manufacturer. The issue already existed when it was only 4 pins but it was minor. Now with 8 pins for moar power and fatter cables you have to rig something out on your own to hold the connector in place, as using it as intended out of the box may damage your system and it will atleast cause it to degrade at an accelerated rate. This can also happen to other power supply connectors but in those cases it is usually either bad cable management or defects from poor quality manufacturing.

Finding a solution is easy when you know the problem. But how many people thinks about buying that when they expect the psu and mobo to have everything needed?

I routed my ATX cable around the back panel. These 4/8 pin connectors are always by the CPU. I'm sure it's done this way for a reason.

Becuase its hella dumb to route long, high current traces. Thats just asking for all sorts of problems.

I wouldn't call a 750w evga supernova powering one of the more expensive gb ultra durable mobos (the op pic is from google) with a single gpu 'mid range'. The thing with high quality components is that they can take a lot of punishment, which is precisely why there are tutorials for users on how to replace the melted connector and can continue using both the psu and the mobo. The most annoying thing about a loose atx connector is that unless you actually need all the power it can provide it is entirely possible for the system to work without apparent issue for quite a while after the connector bends, with your only warning being a slow but steady increase in temps that can be easily confused with dust buildup or the computer "getting old". An extreme example is am3+ users who, while having a functioning fx-8350 setup, decide to try the fx-9000 series, only to instantly melt the connector on first or second try. This is something that can be actually tested, provided that your computer is old enough to be affected.

First take note of the temps as they are now. Next try to gently push the plug to the left. Don't try to force it, if it doesn't go easily it is probably okay and you want to keep it that way. If it does move even a couple of degrees (it is usually the upper group of 4 pins), then find a way to keep it that way without danger to yourself and then note the temps. The drop for a functioning computer goes from 2 to 10 C.

There exists no reason at all to put the computer under the strain of a bad atx connector, particularly given how easy and cheap the solution is. Expecting the manufacturers to fix an issue that is difficult to notice and that mostly kicks in after the warranty has expired might be wishful thinking.

>>818607

The issue is that the connector deviates slightly from the perpendicular. It usually doesn't come out any easier and it may get more difficult to pull out.

>>818551

That is correct, but if you need to place a connector in a difficult place you need to take into account the additional mechanical stress it can cause.

For what it's worth, my company has been shipping embedded boards with standard ATX connectors like that for a decade and I've not heard of a single RMA due to an issue with the plug. So I'm calling bullshit on it being a problem other than build cost/space (we can't afford building our own hardware like Apple). Violent shipping has literally snapped the hooks off of several heatsinks (shipping to Africa or the UAE I think involves dropping the packages from orbit) but the cables were fine.

Gigabyte is on par with MSI, and in a different world than ASRock. I don't even know why ASRock gets mentioned. They are absolute garbage.

The evga supernova is a rebranded super flower that is available in places where the other might not be but the point isn't the brand. There are plenty of examples from asus and it affects both amd and intel. Here are some cases:

That is because the issue isn't obvious. Everyone assumes that it is a bad psu/mobo/cpu and the problem typically shows up only as a burnt connector/boot loop without beeps or even damage to the aforementioned parts which are all pretty generic symptoms. I mean why would anyone think that a plug that is very slightly bent to the side could cause so much trouble.
