Your dad is a pretty smart man (even if he is a bit...frugal).
There's a lot of people on this forum with raging boners for high wattage PSU; even when they don't need them for the modest builds I see being posted. I'll probably get hate replies for it, but it's awful true guys (and any gals).
If you read through our past 5 pages of threads...we all more or less are saying that the good PSU's can be calculated based upon the way you are...
And for people like me that use a larger PSU for my ITX rig, I also already put a rationale up (I parted out my main rig for a temp summer rig and used its parts to subsidize the temp rig)
Those questions are kinda offensive and almost snobbish, IMO. But it makes sense and is really funny. Thanks.
At least you got to convince my dad when I read your TL;DR statement. He's gonna buy an Antec 500W PSU now for about $75. Yazen said Antecs work fine, so I'm gonna take his advice. Seasonic just seems too...expensive.
It was meant to be kinda offensive and almost snobbish....because the only thing akin to your father buying a $20 PSU is something like that...sorry :/
$75 500W Antec? Hope it is a Seasonic Rebrand at least and not another generic........ Best to just buy a Seasonic if you are already spending $75
