[SOLVED] what specifications must a power supply have to keep the other components of the pc healthy?

[Grealish01]

what I mean is what is added by a power supply capable of keeping the PC "healthy" by having more durable and long-lasting components? Is there any particular specific or characteristic that it must have regarding this? In my case I don't care that it has a high failure rate, I care that it makes high components (like CPU and motherboard) last as long as possible. i mean it's okay that in 2/3/4/10 years the power supply breaks, I change it, better this way, but I would like to have a Tagore alime that gives me more safety and longevity on the other more expensive main hardware

Specs?
Buying a non crappy one of sufficient wattage.

ok thanks ...
but I remember that in another discussion you suggested something that had to have a power supply to make the pc last longer

Yes...buy a non-crappy one.

Good quality build psu will have better voltage regulation and less ripple etc. things like these are better for the components in the pc that make use of that same power.

Warranty.

5yrs..good......7yrs...better....10yrs...best.
The longer warranty units are fitting in better parts
You don't want a psu to fail and go down dirty it could wipe out 1/2 the innards of the pc.

Warranty alone is not a total answer just a start.
Read the reviews of your psu pick.
It also does not hurt to oversize a bit.

Not really. Typically it's marketing.

Remember Tommy Boy?

That said, when a "reputable" company only puts a 2 year warranty on a product (looking at you Thermaltake Litepower), you know they have little faith in their product.

That's why you read the reviews.
It's tough to get junk past the reviewers.

Since I left reviewing, I've learned new ways to kill things. 😀

thanks, how do i understand the power supply with the voltages as close as possible to the rated load? how do i calculate the rated load?

hello, thanks for the answer, how much more do you advise me to have as oversizing? (20% okay if you overclock or more?) Else, the more oversizing the better or is it just a safety margin that you don't need to have in abundant quantities? (like more than double more)

Rough estimate.
Take the tdp of the cpu and the gpu and double it.
Now go out to the next size psu.

Ex.....cpu/100w....gpu/200w equals 300w x 2 equals 600w.
Shop for a 650w or bigger psu without going nut-so.

You don't want some off-the-boat psu.
There are also psu calculators which you can plug in stuff and see what they say.

comes back to the answer of "get a good quality psu".

how do i calculate the rated load?

Voltages are ATX spec, 3.3V/5V/12V, the closest they stay at that target the better, again a good psu will do that.

ATX -specs/ Wikipedia, the free encyclopedia
