The Differences between All Corsair Power Supply Units

Most Corsair PSUs are made by Seasonic, one of the most reputable power supply unit manufacturers in the PC world. Legend says there is a chance Fitz were using them to power the servers on the Zephyr…

"Most Corsair PSUs are made by Seasonic"

Is this still true?

No. It started out this way, back when Corsair started making (or rather, selling) PSUs- These days they hardly use Seasonic, if at all. Probably too expensive or margins are too low.

 

[AusWolf]

Sounds like a strong recommendation

I would have rather said "hard recommendation" for pun purposes, but "strong" will do, I guess.

"Most Corsair PSUs are made by Seasonic"

Is this still true?

I don't believe so. The popular CX series are built by Great Wall, HXi series were built by CWT (at least were a few years back, blue label HX1200i), the flagship AXi models (1200i, 1500i and 1600i) are Flextronics. They did use Seasonic for the analog AX (non i, AX1000), more recently, though, and those were amazing power supplies. One of the last few Aris reviewed for TPU.

Corsair AX Series 1000 W Review

At $240, the Corsair AX1000 is certainly not cheap, but it is the best PSU we ever tested. Being built on a Seasonic platform, only top-notch components are used, making this one of the most recommended 1000 W PSUs you can get today, if your system needs much power.

www.techpowerup.com

Corsair is a very large vendor, so their products are built by tons of OEMs. Some OEMs have poor manufacturing compared to others, but the input from the vendor is always a consideration, for example, HEC or CWT power supplies aren't necessarily mid, just as Seasonic power supplies aren't necessarily setting a benchmark of excellence. The Seasonic S12 III, for example, is literally group regulated trash built by a Chinese OEM.

I wish Cooler Master would do a rerun of this power supply, I'd certainly purchase one. Perhaps a 2000 W this time around... pretty please?

Cooler Master MasterWatt Maker 1200 MIJ PSU Review

Cooler Master recently introduced the most expensive desktop PSU ever, but is the MasterWatt Maker 1200 MIJ (Made In Japan) really worth $1,000?

www.tomshardware.com

I discarded the Antec , thanks to Geminis for point me the fact that is a PSU SFX-L format , and after reading the specifications the cable are way to short for my current case.

Now I'm between having more spare watts or taking the best option quality wise from what I read at the internet :

• Seasonic Vertex GX-750 (ATX 3.0 / PCIe 5.0) , Price 222 USD
• Cooler Master GX III 850W Gold (ATX 3.0 / PCIe 5.0) , Price 190 USD

About upgrading in the future , I dont know , I just upgraded to this 4070 ti super and I upgraded to the 7800x3d about a year ago , so ,I guess if nothing weird happens , I will just stick to this setup for a few years.

I just wonder if there is that much of quality difference between these two PSU or grabbing any of the two is an excellent option.

The GX III is higher wattage and cheaper. Seems like a no brainer to me, unless Cooler Master has poor RMA in your country.

 

[Waldorf]

@Garra
CM seems to be a solid unit, but crappy fan, and while not bad, trailing others for ripple/transient, 12VHPR plug is good for only 450w, so too expensive.

maybe this as another option
Thermaltake GF3 850W

Any company has poor RMA here in Uruguay , you normally only get the warranty from the vendor itself and thats all. And most of the products have 1 year warranty. Im more inclined to go with the Cooler Master yes but like Waldford mentioned I have seen a few comments about the fans no being that good and making noise on higher loads.

It is not , I only see available de GF2 version of 850w

 

[Waldorf]

as long as you dont care about the fan control being more aggressive (ramps up sooner, so grts louder than it needs to be), its a quality unit as well.

The thing is that I was looking to be ATX 3.0 and PCIe 5.0 compatible , the GF2 is not

"Most Corsair PSUs are made by Seasonic"

Is this still true?

Seasonic mostly made the HX line for them as an OEM but corsair designs their units in house and/or along side their oem partners. They have used CWT from day one along with other partners like great wall, HEC, chicony, flex. Since it's their design they can take units from one OEM to another.

Hi All ,

First of all , my specs are :

-R7 7800x3d

-Ram 32 gb ddr5

- RXT 4070 TI Super

I play at 4k if that helps with power consumption details.

Well the thing is that I had a Seasonic Focus GX-750 which I bought on 2018, yesterday I suspended my machine and today it didn't power on, no mobo lights ,nothing. After testing with another PSU that I had ( Sentey 600w) , I saw that the mobo turned on its lights , which for me is a good sign that my PSU died.

So , now I'm looking for a new one , at my country (Im not from US) I have 3 valid options around the 200 usd mark :

• Seasonic Vertex GX-750 (ATX 3.0 / PCIe 5.0)
• Cooler Master GX III 850W Gold (ATX 3.0 / PCIe 5.0)
• Seasonic Focus GX-750 (ATX 2.0)

Im having some troubles to choose between these PSU's, I like the FOCUS GX-750 but I read that the others are better because the ATX 3.0 / PCIe 5.0 compatibility .

What do you think ?

Thank you very much in advance"

• Seasonic Vertex GX-750 (ATX 3.0 / PCIe 5.0) - quality unit although a bit pricey for the performance. "Competes" against units like the corsair RMx although it's a bit better
• Cooler Master GX III 850W Gold (ATX 3.0 / PCIe 5.0) - quality units designed by CM w/ excellent efficiency (even better than the Vertex above). Not crazy over the OEM but give credit to the performance, you can argue for the same price it's on par or even better then the Vertex
• Seasonic Focus GX-750 (ATX 2.0) - great unit back in the day (I own one) but if you have a RTX 4070ti then get a ATX 3.X PSU with proper connectors as opposed to using adapters

either the Seasonic vertex or CM, whichever is cheaper would be the one I would get. Skip the older Focus

some of the latest Seasonic are subpar when compared to previous ones

they definately took cost cutting measures on their new focus line, still good but not as good as one would expect

Obviously Seasonic

blind faith towards any brand is never a good thing

Antec is good.

they seem to have back tracked from paying much focus on their PSU line after they were sold, defiantly not the antec of old when they were a major player in quality PSU

No. It started out this way

actually it started out with Seasonic & CWT with CWT making most of their units then as they do today

CM seems to be a solid unit, but crappy fan

is the yate loon fan or the fan controller being too aggressive? I believe other units use that same fan including ones from corsair

My issue with Corsair is that they have way too many product lines. It's hard to keep track of which ones are good and which ones not so much.

Don't look at super flower or Be Quiet than. How many different ways can you repurpose leadex and "Power" across your product lines...

"Most Corsair PSUs are made by Seasonic"

Is this still true?

There should be a law that requires all articles that make statements of fact be timestamped. Shrek's article does not have a timestamp. That could lead to some believing that statement was still true. Fortunately, Shrek's spidey-sense gave him concern.

Scanning through the article's comments, I see the earliest comment is dated 2014, 11 years ago! Back then, it may have been true that Seasonic made most of Corsair supplies. IDK.

But according to this Cybertechnosys article, dated March 2024 ( ), Corsair now (or at least in March of 2024) makes their own.

Are Corsair Psu Made By Seasonic?

Corsair PSUs are not made by Seasonic. Corsair has its own manufacturing facilities and designs its own power supplies.

I sure wish Corsair themselves (all brand makers actually), had something on their website that either said they do design and manufacturer their own supplies in their own factories, or that they partner with this OEM for this, and that OEM for that. But it appears they don't make that public so not sure how any article author can make any such a statement without some sort of authority since it is unlikely they purchased samples of every model Corsair currently make, then sussed that information out.

Thanks for your answer!

The cooler master goes for 30 usd less than the Vertex , in fact I can get for the same price (USD 225) as the vertex the CM GX3 but the 1000w version , the 850w version cost 190 USD. For now , Im almost decided to get the CM because of the good reviews (despite the loudly fan) and also the pickup store is near my home

 

[Shrek]

Nice catch.

 

[dirtyferret]

CM because of the good reviews (despite the loudly fan)

with a RTX 4070ti you are going to be around 350-425w total system power while gaming, that PSU doesn't start to build up noise until you pass 500w (and that still a subjective noise level at that point). If you were going to push that unit, yes the aggressive fan profile would be an issue (and I'm a noise freak so no loud fan noise for me)

 

[Solid State Soul ( SSS )]

The Corsair RMx 2024 is the best gold power supply money can buy today according to hardware busters, Seasonic is fine but overrated and the cooler master is slso fine but not better than the Corsair

Also check super flower leadex vii gold they are great as well

 

[dirtyferret]

But according to this Cybertechnosys article, dated March 2024 ( ), Corsair now (or at least in March of 2024) makes their own.

I don't think that's accurate. Corsair designs their units in house but they don't manufacture them in their own plants. Typically PSU manufacturing is such a large scale project you need to also make them for other brands (like Super flower, FSP, etc.,). I think Silverstone may have been the last brand that I recall had their own plant (not even 100% sure on that) and they stopped that.

I sure wish Corsair themselves (all brand makers actually), had something on their website that either said they do design and manufacturer their own supplies in their own factories, or that they partner with this OEM for this, and that OEM for that. But it appears they don't make that public so not sure how any article author can make any such a statement without some sort of authority since it is unlikely they purchased samples of every model Corsair currently make, then sussed that information out.

Thing is does it really make a difference to the Joe consumer (for the more passionate people yes it's fun to talk about)? Honestly most of these OEMs are really ODMs. It's their design, the brand just gives them a budget. A true OEM is using the brand's design and builds to that brands standards. On our products, we have the patent and we can take it from OEM to OEM (and in china they can take it behind out backs) but if it's an ODM product you are basically stuck with the manufacture. Corsair and CM have excellent in house design teams but that doesn't mean a brand like Phanteks using Seasonic as a ODM can't have excellent units as well. My point, not to de-rail the topic too much, is that each brand-OEM/ODM relationship is different so saying CM using Lite-ON sucks because another brand used them as an ODM isn't really apples to apples. Also, even OEM/ODM like SF & Seasonic will use outside manufactiers for certain lines and large runs.

Corsair RMx 2024

RMx 3.1 line, sometimes the year thing can be difficult to understand for some people as there are RMx 3.0 reviews from 2024

@Shrek this line from that article...

However, it is possible that Corsair may use Seasonic components in some of its own power supplies.

 

[Bill_Bright]

I don't think that's accurate. Corsair designs their units in house but they don't manufacture them in their own plants.

Based on what? A hunch? Got a link to support your claim? I am NOT saying you are wrong - but who's to say you are right? Where's your supporting evidence?

Corsair is a HUGE $billion corporation. According to Wikipedia, they lease a big production facility in Taiwan. They also have manufacturing operations in Atlanta, GA, USA.

Just because they "lease" the facility vs "own" is immaterial. I worked for Northrop Grumman IT (NGIT) for many years. We had a huge facility with 400 developers and 10 hardware techs (I was one of the techs) supporting those developers. It says "Northrop Grumman Information Technologies" on the building. But does "NGIT" own the building? No! Why? Because Northrop Grumman is not in the real estate business.

There is a HUGE bakery about a mile away from here. This bakery does NOT produce their own brand breads. Instead, the major bread brands (Wonder, Sara Lee, Pepperidge Farm, Great Value/Walmart, Kroger and others) contract with this bakery to make their breads. Wonder and Sara Lee and the others provide the recipes and ingredients, the bakery bakes them according to the brand's directions. The loaf of Wonder bread is still Wonder bread, not this bakery.

Is Wikipedia the Gospel truth? Of course not. But what says dirtyferret is?

To be clear, the difference I am pointing out is, from the supporting evidence I have provided, Corsair is NOT buying supplies from Seasonic or another OEM, then rebranding them with their own brand name - as so many hardware "makers" do.

Instead, according to corroborating evidence I provided, Corsair is designing their own supplies AND manufacturing them in their own facilities - the fact the building they manufacture those products in may be own by someone else does not matter. Corsair, or their designated contractor, is running the manufacturing process.

 

[Waldorf]

@dirtyferret
at least from what reviews i read, it wasnt about the noise, but quality of the fan (CM), only the Tt was noisy, but more because of the controller.

i dont care to swap fans on a unit of everything else is great, but even at the cheapest you could get the CM anywhere, i would expect them to spend more money on a fan, not like its going to be more than 10$.

like giving up 10ft before the finish line...

 

[Bill_Bright]

not like its going to be more than 10$.

Considering they must buy 100s of 1000s per order, I would suspect closer to $1 than $10. It is not like they are proprietary either. They typically are of a standard size and operating voltage too.

like giving up 10ft before the finish line...

Just to save a couple pennies.

 

[dirtyferret]

Based on what? A hunch? Got a link to support your claim? I am NOT saying you are wrong - but who's to say you are right? Where's your supporting evidence?

I've never scene an in-house manufactured review of a Corsair PSU. They were all built in other factories even when designed by Corsair themselves but perhaps things have changed and @jonnyGURU can enlightened us if corsair now owns their own PSU manufacturing facility. They have to be cranking out some serious number of units if that's a feasible option.

wasnt about the noise, but quality of the fan (CM), only the Tt was noisy, but more because of the controller.

interesting, I don't recall hearing other reviews complain about that fan (I'm not doubting you) but Bill's right those fans don't cost much.

 

[freeagent]

Corsair does not actually build anything afaik, they design locally, and farm the work out to factories in Asia

 

[Frick]

Corsair is a HUGE $billion corporation. According to Wikipedia, they lease a big production facility in Taiwan. They also have manufacturing operations in Atlanta, GA, USA.

I'd think if Corsair is making their stuff in-house we'd know about it by now. Also please for the love of [insert whatever you like], do consider what the words "I think" mean.

Instead, according to corroborating evidence I provided, Corsair is designing their own supplies AND manufacturing them in their own facilities - the fact the building they manufacture those products in may be own by someone else does not matter. Corsair, or their designated contractor, is running the manufacturing process.

So following the source link and doing a word search we get this:
"Production and Operations:
We believe we have developed a global and scalable production and operations infrastructure that allows us to deliver our products promptly and cost-effectively. We operate a facility in Taiwan where we assemble, test, package and ultimately supply nearly all of our DRAM modules and a significant portion of our customized gaming controllers, liquid cooling products and prebuilt gaming systems. We also assemble, test, package and ultimately supply our custom-built PCs and our customized gaming controllers and fully built PCs from our U.S. facility in Atlanta, Georgia. All of the other products we sell are produced at factories operated by third parties located in Asia. In addition, we outsource storage and shipping to several third-party logistics providers around the world which allows us to reduce order fulfillment time, reduce shipping costs and improve inventory flexibility."

 

[Waldorf]

unless its for the past few years, never seen anyone with knowledge about these things state corsair made them (factory, not just design).
especially when i remember not just "one guy" opening them up, to compare build/components, with some units being very similar to other units when it comes to components,
making it more likely to be made by oem, that has more than one brand made in the plant.

 

[Bill_Bright]

I'd think if Corsair is making their stuff in-house we'd know about it by now.

So do you believe if a company is manufacturing products of their own design, but doing so in a facility they don't own, but only lease that is not considered in house?

Intel, for example, does NOT own all the foundries their products are manufactured. The products are made to Intel design and specs, and production is overseen by them. So does that mean it is not in-house?

Once again I say,

To be clear, the difference I am pointing out is, from the supporting evidence I have provided, Corsair is NOT buying supplies from Seasonic or another OEM, then rebranding them with their own brand name - as so many hardware "makers" do.

for the love of [insert whatever you like], do consider what...

...what I said too.

 

[dirtyferret]

But does "NGIT" own the building? No! Why? Because Northrop Grumman is not in the real estate business.

just FYI, really has nothing to do with being an OEM or ODM

There is a HUGE bakery about a mile away from here. This bakery does NOT produce their own brand breads. Instead, the major bread brands (Wonder, Sara Lee, Pepperidge Farm, Great Value/Walmart, Kroger and others) contract with this bakery to make their breads. Wonder and Sara Lee and the others provide the recipes and ingredients, the bakery bakes them according to the brand's directions. The loaf of Wonder bread is still Wonder bread, not this bakery.

this would be a more apt example; Wonder, Sara Lee, P-Farm, etc., would be the brands. The bakery the "OEM" since they are following the brands recipe and part selection. If the brands simply went to the bakery and said, hey make us a loaf of bread for $1 each loaf that we can sell, than the bakery would be the "ODM" since it's the bakeries recipe. If the brands made the bread in house (like P-farm used to but now outsources) than it would be made in their own facility regardless if they owned or rented the bakery building itself.

So do you believe if a company is manufacturing products of their own design, but doing so in a facility they don't own, but only lease that is not considered in house?
