Is the CM mwe bronze V2 known with coil whine?

[hyrix7Q]

so guys I'm planning to get a CM MWE 650W bronze V2 
and I saw some reports that it's known for coil whine!  but most of the reports were talking about the V1 
so is the V2 different  ? 
I already have coil whine on my gpu so I don't want another on my psu too 
what do you think guys because  if it's known for coil whine so I should avoid it ! 

There is no corsair or evga in my country 

specs :
RYZEN 5 2600x
MSI GTX 1660 GAMING X
ASUS B450M-K PRIME

id think if the first had that problem, the v2 would have it fixed.

They're completely different, V1 is older double-forward design, which are known for coil whine, V2 is newer, more advanced design by completely different OEM, with LLC which generally means that it shouldn't have coil whine but since that OEM is fairly inexperienced in PC PSUs this design ended up being flawed, with higher than expected ripple at low load and therefore coil whine (which is nothing more than transformer, inductances and capacitors filtering out ripple and converting it into heat and sound).

TLDR: Yes, both of them, V1 and V2 are known for coil whine.

It is, if cheap enough and you don't have better alternatives.
