can a low quality psu increase temp of pc all parts and gpu?

[pratik2011]

few days ago i run i machine with a low non brand psu due to some reasons... i think that time the temp was little high...
my question is can a low quality psu increase temp of pc all parts and gpu?

Yes, it can although it shouldn't.

If a low quality PSU is not using high quality transformer and capacitors it can result in a bad watts to amps ratio, requiring that the components draw more power to get the amount of amperage it needs. More electrical draw = more heat.

Also, if the PSU is having to work harder to keep up with the system it can be putting hot air into the case.

Yes, if it has bad cooling design.

A low quality psu can do all kinds of things including frying your entire system because it has no protections, meltdown if you try to run it anywhere near the overexaggerated wattage rating, system instability, crashes, and hardware failures.
