Which PSU is better?

[SunRise-]

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?

They both make excellent, Average, and sub par power supplies. You really need to look at a specific model.

I like the RMx line out of the 3 you have chosen if the HXi is about the same price sure otherwise it is not worth more than a 30 usd price premium.

The Focus GX is solid but I would go 1kw assuming they are priced similarly.

Listing your current system specs would be pretty helpful in determining what psu you need going higher in wattage isn't a bad thing but depending on your current system or future plans for upgrades a 1kw psu may not make sense.

 

[R0H1T]

Of the three Hx1000i is the best of the lot but also pricey, depends on where you are though.

What is your budget for this PSU and system spec. To be conservative 1000w is on the safe side if you plan to change hardware in the futur.

Invest in platinum or titanum quality power supply. You don’t want some garbage and searching for coil noise or other problems later in your setup...

 

[Double-Click]

What are your system specs and/or plans for the rig?
850-1000W might be way more than you ever need depending on things.

Both brands can offer a range of quality as said, one difference between them is Seasonic is an actual OEM.
You're not going to go wrong with either really just get something gold rated and with a good warranty.

If you are looking at >=850W PSU, I would safely assume you are using / planning to upgrade to a high-end GPU. Don't forget about ATX3.0 compliance.
IIRC the 3 models OP listed doesn't explicitly state ATX3.0, but all 3 should be fine, and you guys know better.
If you are sure you won't go for high-end GPUs, and you don't use power hog CPUs, 1000W (and probably 850W) doesn't make much sense.

I'm also not going to say you must use Platinum, but don't go anything below Gold. You will struggle to find anything below Gold at that kind of wattage from that kind of brand anyway.
On my side of the world, for 1000W~1300W units Platinum is about 25% more expensive over Gold, and Titanium is 75%~100% over Platinum models. Consider local pricing vs budget, how you value efficiency and noise output.

After you refined your requirements and choices, if you still can't decide on which one you want to buy, you may try your luck leaving a comment on the link @Phil_Frenchy provided. Aris sometimes will check the comments and give answers.

Another thing.Why many new brand of PSU have idle Fan Stop like GPU?Some PSU fans don't start until they reach 65 degrees.I read on their description,and i don't believes my eye.
For now i have an weak PC,but i intended to upgrading in the future.that's why i planning to purchase a better and expansive quality PSU, because I heard that the PSu is the most important part of the PC, and and a high-capacity PSU will not have current losses(bad efficiency) like a small one, and the electric bill will be even lower with a Platinum than a gold or bronze.
For example I heard a strange thing. A 1000w PSU with platinum spec. have much better efficiency and LESS electric bill than a PSU with 650w with gold rated.
That's why i will choose a big capacity wattage PSU even if I don't need it.The electricity bill will also save me

 

[Vya Domus]

If these are your choices I'd pick the RM1000x, HX1000i is extremely overpriced and 850W is not a smart choice given how absurdly power hungry GPUs are getting.

 

[Todestrieb]

idle Fan Stop

As long as they are not too hot, I don't see any issue. Not that 65C is too hot for the components inside.
And it shouldn't be that hard to find a quality PSU that can disable idle fan stop feature.

but i intended to upgrading in the future

How high-end do you intend to upgrade?
For me personally and for current gen, anything below 7800XT / 4080 doesn't warrant a 1000W PSU upgrade. If they are indeed in your upgrade plans then go for it.

For example I heard a strange thing. A 1000w PSU with platinum spec. have much better efficiency and LESS electric bill than a PSU with 650w with gold rated.

(Rated wattage of PSU) =/= (Power draw from wall)
And...
( Sum of power draw of components ) / ( Efficiency of PSU ) = ( Power draw from wall )
( For the sake of simplicity, I skipped the efficiency difference in different voltage rails.)

A PSU in general operates most efficiently at ~50% of it's rated wattage, so, as an example, assuming a PC draws 500W and component quality is the same otherwise, a 1000W gold will be more efficient than a 650W gold.
But, and this is a very BIG BUT, price difference is normally too big for efficiency to actually matter in terms of electricity bills. Unless you want high efficiency for the sake of high efficiency, or you really really really really want the absolute best PSU available, it just doesn't worth pursuing the Titanium rated units and overly highly rated PSUs.
A quality unit, Platinum/Titanium or not, will last a very long time anyway.

@SunRise-

the Hx is overpriced if you consider the difference over the RMx,
unless it includes a feature you absolutely "must" have.

going with 1Kw plat over say 850w gold, is very likely to cost you more at time of purchase,
than what you will ever "save" during the use, unless you pulling +50% load 24/7...

@Phil_Frenchy
the efficiency rating has NOTHING to do with (build) quality.
enough units with gold rating that are utter crap (cant speak for plat/tit, as i havent looked at psus lately),
while some bronze unit are "beating" them.

make a decision based on efficiency, is one of the "worst" advice for buying hw/parts.

You will encounter more Good build quality units with a higher efficency rating than the reverse...

another question.For hungry graphic card is better to choose PSU with one 12v single ray or with 2 rails 12v?

 

[kapone32]

The only reason the get the HX1000I over 1000M is if you want to have HWinfo show your PSU data. Those I class PSUs come with a USB connector for the MB. If you want to change the fan profile you must install Icue software though.

 

[Waldorf]

@Phil_Frenchy
the facts dont change, just because we dont like them.
"most" doesnt mean ALL (units), and completely ignores the fact that not every market/country/shop has the same brands/units,
so ppl could still pick a unit (by chance), you wouldnt want to even plug in (outlet), so there is no way to know what ppl might end up with.

referencing psu tier list from a different site:
-possibly dangerous : 7 brands (out of 14) includes ALL their units, no matter output and/or rating.
-units only recommended for i-gpu/cheap stuff incl a titanium/plat unit.
-tier for cheap/low end incl almost 10 plat units.
-and even mid range still has 4 plat/titanium units (i wouldnt buy),
all while 15 GOLD units are rated "best" tier (1-3 tiers ABOVE some platinum/titanium)


feel free to support your claim with psu lists from more than 3 larger sites testing them, and i will gladly change my view.
until then:
efficiency rating is for RATING EFFICENCY, not (guaranteed) build quality,
and even then, its not automatically the better deal, as wasting another 50$ for higher rating (than gold)
to save 10$ (over its life) in energy cost, doesnt make much sense.


@SunRise-
depends, higher output a dual is fine, if you want to split "loads" (e.g. goin gofr biggest cpu/gpu chip wise).

i would rather look for transient loads coming from gpu (reviews),
sometimes can be a (possible) issue, ppl overlook.

 

[Zach_01]

I dont really know if HX1000i is related directly to the HX750i(blue) that I have...



...but this thing is a little beast

92% rated platinum efficiency, 750W max output and it keeps growing efficiency (93+%) even at 600W (80% load)
The stop fan function is really nice one as the PSU can take up to 350-400W (sustained and not peak) without the fan working if cooled air is feed to it.
And keeps it dust free longer
Remember that platinum efficiency is not only meaning just 2-3% less power losses but also (in reverse) 20-30% less heat dissipation from losses compared to a Gold one (losses of 7-8% vs ~10%)

Here you can see the fan still spinning cause its right after 2hrs of gaming session. It stops in a few mins.

That is what the I has stood for. There was a digital model that did not need the USB cable but that only had one release years ago.

Yes I know what the (i) stands for, its digital, but Ive seen some (i)s with different color (black/gray and not black/blue) and I cant vouch that they are the same quality wise.

I had a 1200! for about 8 years and loved it. When I got my 6800XT it started to give me black screens. I refused to believe for several posts until I got a Deepcool 1000 and it has been smooth sailing once again. I was going to get the I but the price was more than I was willing to pay for the Corsair tax. I used to be more into HWinfo but I spend most of time Gaming on this machine now. TPU is just a break. I have a new Mod Map for TWWH3 that makes the map look like Pangea. It will probably take me a year to complete.

 

[Zach_01]

There is an option to custom curve in iCUE but you loose the stop fan function which I find stupid.
Goes minimum at 700rpm constantly when custom, and its default minimum is 500rpm when it starts or before stops.
The fan was never spinning when I had R5 3600 and a 220-230W 5700XT on the system... and I loved it.
Not a single grain of dust in it, and temp was like 45C under load.

 

[Waldorf]

thats the main reason i like Seasonic (and others) using a physical switch,
to change psu (fan) behavior, as my rig (as well as me), seem to experience an allergic reaction, when installing icue

Yeah, has its issues for sure, but the default curve with stop fan is working pretty well.
I just like to try custom curves, thats all, but loosing the stop fan is a no go for me as you cant clean PSUs from dust easily like other parts.

 

[Waldorf]

@Zach_01
you have a fully modular unit,
remove it, and any paint shop near you, will have no problem using an air gun to blow it clean.
6-pack of some form of drink (they prefer), works good as a tip.

(i dont recommend because of possible static destroying stuff, but my leaf blower was better than nothing,
as its residential area only, and takes min of 20min of driving (one way).

Can't argue with all that. Not all golds or platinums are created equally.
And GPU transients sometimes can total PSU responsiveness on loads

 

[Deleted member 237269]

@Waldorf And the fact that OFFICIAL knowns brands with recents Higher Efficiency Titanium products have better builds quality in general doesn’t change. You can argue all you want with your little muppet lungs.
I linked an excellent Thread to op with every PSU stress tested under every ways.
@SunRise- it’s now in your hands, good luck buddy. Don’t cheap out on PSU all i will say.
