Did you read what size OP’s psu was. Notice how it deviates from the standard? With different height, length and width. That is why I said it is uncommon, because as you say it’s usually just the length that changes in the ATX form factor.
OP's blown PSU is "Apevia 450W Power Supply" and that unit is crap quality. It's so bad of an unit that it's dimensions even doesn't match to the dimensions of ATX PSU standard,

Never said there weren’t...
And I don’t believe those primes are 140mm: https://www.kitguru.net/components/power-supplies/zardon/seasonic-prime-850w-gold-psu-review/all/1/
Sure you did. Also, you need to get your facts straight. What you linked is PRIME 850 80+ Gold and that unit has 170mm depth. In fact all PRIME 80+ Gold units have 170mm depth,

What i suggested above is PRIME
Ultra 80+ Gold series which is completely different PSU line from Seasonic. And as i said above, PRIME Ultra 80+ Gold 550, 650 and 750 units do have depth of 140mm.

You’re joking right? Did you somehow miss my last sentence? Without full system specs or budget it is quite impossible to know which unit will be “enough”.
The list of PSUs I suggested all are at least DCDC, so filters out a lot of the garbage on the market.
I don't need to know the full system specs and budget to suggest which units are good build quality and safe to use in a system. Full system specs are only needed to calculate PSU's wattage and budget defines if OP is able to go with expensive, great quality PSU (e.g Seasonic PRIME Ultra) or more wallet friendly, good quality PSU (e.g Seasonic Focus+ 80+ Gold).
Clearly you don't know the build quality differences between those units you suggested. For example, Corsair VS series is the worst offered by Corsair and it's a low quality unit. I wouldn't use it to power even an office PC that doesn't have dedicated GPU in it and where PSU never sees any high loads, let alone powering a gaming PC with it.
When you're in the hole, stop digging.
Also, why to give OP a link to the Netherlands site? Just because you can speak Dutch doesn't mean OP can. That, and also if OP were to use your site to buy his new PSU, all the links there link to the local Netherlands stores. For all you know, OP can be from the States with different currency in use (USD vs EUR) and a pond (Atlantic ocean) separating the store and OP's location.

And you never know if Seasonic will last that long. There were many PSU brands that were doing successful 10 years ago, but not at all now. Warranty is just overrated/marketing at this point.
Seasonic isn't just some obscure PSU brand that can go under in 10 years. In fact, Seasonic is one of the oldest PSU OEMs in the world and they have been in business for over 40 years (founded in 1975).
Besides releasing PSUs under their own name, Seasonic also makes PSUs to other popular brands. To name the few: Corsair AX series, EVGA Supernova GS series, XFX TS series, NZXT Hale82 series.
Also, Seasonic hasn't never made a bad quality PSU in their time (unless you count some noisy fans in their older models). PSU build quality wise, Seasonic is the leading OEM in the world. And depending on who you ask, either Seasonic or Super Flower is considered the best PSU OEM in the world.
You have a lot to learn when it comes to the PSUs and i suggest that you do learn more about PSUs if you want to give good advice to others, without saying vague things like: "... that should all be at least decent quality.".
