Old vs New PSU

[Soft Wumbo]

Does PSU release date matter?
we know that old gpu and cpu re outdated,
but how about PSU?

Do u know about this site ? https://www.clearesult.com/80plus/

if u do, does it mean if a psu is not listed here is a bad psu?

[humboldt]

psu's work or dont. thats it mainly. in my opinion one just needs to take a look at its possible output(wattage) for a maybe gfx board. electronic parts are made for forever, because no one can say, WHEN an electronic part will be defective. i do know this/i had a job in elctronics.
i dont want to vist the website you posted. i fear virusses.

Depends, If its a name brand, I'd trust them no matter how old really, Im using a 500 watt Seasonic in my dual Xeon server with a Vega 64 I've had for 10 years, still does honestly more than what I expect from it.

I use to have a EVGA Supernova 1300 g2 that was pretty close to 10 years ago, Recently sold it, only reason was because it was out of warranty, and bought a smaller 1000 watt EVGA unit that fits in my case better, plus got another 10 year warranty with it.

So date I wouldn't say matter too much on a good PSU, a cheapo no name brand, probably pop as soon as its powered on if its 10 years old.

Might google this (good read) - PSU Tier List 4.0 rev. 14.8
it s at Linus Tech Tips

If you need a good brand making PSU - Corsair , EVGA , Sea Sonic , Super Flower ,Be Quiet ! But often the cheap ones are with not very high quality i.e. should be avoided .

Depends.

If you are talking about quite old stuff then there's the capacitor plague from ~1999-2007.

What mainboard and gpu do you use? Buy stuff for your current pc or if you are upgrading soon your next pc.

i also dont want to buy no name or a new brand psu, but i always visit that site as my reference, but i cant find an answer in single online forum about it, is that site good as reference.

i did research on linus psu tier, but there are not many psus, so i cant use it as reference.
still wondering about the site that i posted above, is good as reference?

80 PLUS Certification is not any indication of quality, merely how efficient a power supply is. You can use garbage components and get a decent 80+ rating, and many units actually lie about their rating and pretend to be a Gold when it's more likely a Bronze, for example.

If you want to know which ones are good, just look at tier lists, the one on the LTT forums doesn't have units released in 2022 onwards but it's good enough.

If you want a high tier PSU that isn't too expensive, look at:
Corsair: RM/RMe/RMx series (between 2018 and 2023), TX-M Gold
EVGA: SuperNova GT series, GS series
SeaSonic: FOCUS Plus Gold, Focus GX

^ this
80+ does not test for ripple/noise or if its even in the atx spec, just how efficient it is

[Overseer]

Depends on how old. Even specs changed over time as the now really old ones had much stronger 5V rails, whereas todays PSUs shifted towards 12V rails while neglecting 5V.

[Phénomènes Mystiques]

EVGA has to be the best PSU manufacturer with the lowest prices and better warranty.

I haven't checked their prices lately but where I live the prices on Corsair psus have gone up at least 50% since last year.

[Supafly]

Pretty sure any PSU with a long warranty, 10+ years, will be of a high tier when checking PSU Tier Lists

them shall be loud...as far as i know. go for seasonic or the more expensive bequiet ones. i have a noname psu by CSL, germany. it is very well and quiet. maybe one of these?

[A&A]

Still working 2003 seasonic 350W PSU.
Not bad at all!

[Raoul]

Are you actually asking about ATX PSU specifications like new connectors and standards?
https://en.wikipedia.org/wiki/ATX check here scroll about half way to ATX power supply revisions.

Or you just mean life span ratings? https://en.wikipedia.org/wiki/Power_supply_unit_(computer)
Check here near the bottom where it says Life span.

what does speculative position mean on LTT PSU Tier?
last question, so is this nonsense to check psu on https://www.clearesult.com/80plus/ ?

it works and is always a good choice to let a psu calculate. you can do the same on, for example, the bequit website. the theory of calculating a psu is easy and works for sure.
have a nice day.

just go by cpu+gpu wattage and double it, maybe more
most psus are most efficient at around 50%
never good to run at psu at its max, since there are multiple rails each with their own limits

generally
300-400w with no dedicated gpu
600-800+ for gaming build
1000+ for multi gpu build

avoid anything that say 85+, those are not even a spec
