Remember just because it says does not mean it is...research them individually.

I want to change my PSU,because have already 5 years of usage ,and i am not sure my current psu deliver optimal power for my graphic card.My curent PSU is a "no_name brand" and i decide to purchase Corsair or Seasonic PSU.
I found a bunch different model of PSU and i am wondering which PSU have better internal quality and which is better for gaming?I don't know what to choose

1.Corsair RM1000x
2.Seasonic Focus GX, 80+ Gold, 850W
3.Corsair HX1000i

generally speaking.....which brand is better Seasonic or Corsair?

​

Evga Supernova 1000 G3 is good?
Evga 1000 p2 is good?

Evga Supernova 1000 G3 is good?
Evga 1000 p2 is good?

Yes and yes, both are excellent units but I would encourage you to take a look at something in the ATX 3.0/1 platform. Buying an older platform unit will save you money short term but going with a newer platform may avoid the need to buy another PSU down the road.

Seasonic Vertex GX or PX, great (low) ripple on all rails in the reviews ive seen. Amazing warranty, quiet units, 3.0 support, and the new cable design is quite good.

Corsair seems to be on the downward quality trend with all their products (and up with price???).

I've had both, slightly small and bigger units but the G series I've had issues with and I sadly won't recommend them anymore. The P range is better but it'll cost.

I've moved over to Seasonic GX units, I've a PX around here somewhere but only because I was buying it second hand and it was a steal.. Couldn't resist.

No issues at all with the Seasonic stuff so far, been running 4 or 5 of their units for a good 6 to 8 months now, no issues yet GX850 models I've a 1600T2 for my Threadripper and RTX 3090 which has been flawless as well, it just carries on regardless but its only really using half the power capacity currently...
I still have some Corsair AX1200 - not the digital models, I found they sucked and haven't last but the 1200w models I do have still, still going strong and I bought them back in 2010 or 2011 I think. They are in my EVGA X58 Classified builds (I've three of those - 759, 762 and SR-2)

I can honestly say spending a bit more on a PSU is definitely worth it as it could save your hardware and basically last a decent amount of time. I've always stuck with the 'A' list of PSUs but as long as you go for the best you can 'afford', then you are in the right area Spec'ing the right size will also help but not as much as getting the right brand/OEM.

@Phil_Frenchy
except that wasnt your argument early, and still wont change the fact that there are enough crappy units above gold,
that means blindly recommending to go plat/titanium for quality, is still wrong.

again, (you cant) name 3 large website that review and test psu's, that support your claim,
otherwise you would have already.

especially since you had to try and belittle me.
thanks for showing me early, that i need to add you to my ignore list.

@SunRise-
looking at long term use, future upgrades, as others said, your better off with a gold unit of the latest (tech),
than a (previous gen) plat unit..

 

[Solid State Soul ( SSS )]

all of them are good, make sure you buy the ATX 3.0 compliant versions, if all of them do support it, buy the cheaper option, between the seasonic or RMx

 

[67Elco]

Like I alluded to earlier...the terms Bronze, Gold, Platinum, ect. have zero meaning or credibility anymore and would be a poor measurement for selecting any psu.

How can i recognise a psu with ATX 3.0 capabilities?And another question, if ATX 3.0 is compatible with ATX 2.0 ?

Should say in the specs; also will have a 12vhpr connector.

It’s backward compatiable.

Hardwarebusters is a great source for finding solid units if your not sure what to look for.

You can check cybenetics for testing reviews as well.

Cybenetics Labs – PSU Efficiency & Noise Level Certifications

www.cybenetics.com

i thought Titanium efficiency certification is the latest,but i was wrong....Diamond is. lol. i think Diamond have 99.9% efficiency

More likely 97-98 tops... a tiny fan (or very low rpm one) could keep it cool... or be fanless in small wattages (if small units will exist)
For 600W output and 97-98% eff the heat will be like ~15W. (615W on socket)
For a gold that would be around x3.5 more heat.

EDIT:
Oh yeah and the price will probably be a few diamonds also...
