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.

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.

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.
