So... if the PSU destroys like for example the motherboard and I still have my warranty, can I get a new one from the motherboard manufacturer?
I'd say no. Few examples as well:
MSI
Warranty Exclusions
The following circumstances excluded from warranty coverage
Product damage caused by catastrophes, thunder stroke, faulty electric power and environmental factors.

When the low quality PSU blows up, it usually sends power surge to anything it's connected to. And it doesn't take much excess voltage to fry MoBo's voltage control unit/chip. E.g +12.6V is still safe but if PSU delivers more than that via +12V rail, e.g +14V, MoBo can't handle that.
Asus
The warranty will not apply to or be valid under conditions including but not limited to the following:
There is damage caused by natural disaster, intentional or unintentional misuse, abuse, neglect, acts of war, improper maintenance, or use under abnormal conditions;
There is damage caused by accidental drops, spills, fire, or power surges.
There is damage from improper installation, improper connection, or use of parts and/or components not manufactured or sold by ASUS;
There is damage from use outside of the operation or storage parameters or environment detailed in the User's Manual or reasonably acceptable for similar product usage models deemed industry standard best practices;

One of the abnormal conditions are the voltages outside of ATX PSU standard. And according to the ATX PSU standard, safe voltage ranges are:
+12V DC rail - tolerance ±5% ; +11.40V to +12.60V
+5V DC rail - tolerance ±5% ; +4.75V to +5.25V
+3.3V DC rail - tolerance ±5% ; +3.14V to +3.47V
-12V DC rail - tolerance ±10% ; -10.80V to -13.20V
+5V SB rail - tolerance ±5% ; +4.75V to +5.25V
Anything lower or higher than that aren't safe for PC components. Lower voltage can cause data corruption while higher voltage can fry components.
It's like when you put cheap, low quality fuel into your car and it ends up seizing your car engine. Is the car manufacturer responsible of your neglect? No, they are not.
You can cheap out on every other component inside the PC except PSU. Since PSU powers everything, it is the most important component inside the PC. Also, while the PSU warranty covers the PSU itself and you can RMA the blown PSU, the PSU warranty doesn't cover any other component the PSU fried.
Most people learn the hard way not to cheap out on a PSU when low quality PSU blows and takes part of the system or the whole system with it. Even entire houses have been burned down because of the fire low quality PSU caused when it blowed up.
Like it or not, if you want your PC to work for years to come without any risk of fire and/or damage to your components, you need to hand out some money for good quality PSU. I'm not talking that you need to go with the best 650W PSU available, e.g Seasonic PRIME 650 Titanium which costs $150+ (and which also powers my Skylake build). Seasonic G-650 (
LINK) costs $79 and is more than enough for your PC, both wattage and build quality wise.
