Seasonic vs Corsair PSU

[zeltrabas]

So in September (or when new GPUs release) im building a new pc.

But i dont know what PSU to pick. Im deciding between a Corsair AX 850W Titanium or a Seasonic Prime TX-850.

Is there a big difference between the two? I heard the Corsair one is more silent, so that's my preference, but I still dont know which one to get.

Any recommendations?

[MrBrightSyde]

Why would you need 850w and why would you need Titanium efficiency?  Even with a 10900k and 2080ti OC'd under full load, you wouldn't need more than 650w, unless you are doing something like a dual GPU system.

 

As for the efficiency, let's say you are from the US and power costs 16 cents per kWh (using California's power prices) and you run your PSU at 50% load for 10 hours a day. You would only be saving about $4.50 a year compared to a Platinum rated PSU (only ~$3.50 if power is 12 cents). Cheapest Titanium PSU right now is the 700w Strider Titanium for ~$154 (rounding up for easier math) while the 660w Fractal Design Ion+ Platinum is $121. You would have to use the Strider for about 7 years to make up the difference up in savings (over 10 years if power is 12 cents or cheaper). It just doesn't make sense to get a Titanium PSU unless you are going to re-use it for about a decade or if your system will be running under full load 24/7.

 

Basically, don't buy a Titanium PSU unless you are running a server off of it or mining, or if you are going to use it for over a decade. Also, I'm advocating for the Fractal Design Ion+ Platinum 660w as the PSU for your build as it also operates silently.

I only buy seasonic PSUs now, because they make all of them themlselves.

Also usually their PSUs have a hybrid fan mode that is off until like 50% load or whatever, so 90% of the time it is completely silent.

Plus other great features like all sesonic cables are cross compatible if you ever buy sleeved cables, longer warranties, better voltage regulation, etc.

[SPCFHT]

The OEM of the Corsair PSU is Seasonic

Check the PSU tier list on the forum.

Also to add, the AX is basically the Prime TX, they use the same platform and are both made by Seasonic. So it literally is, "which ever is cheaper"

[5x5]

Considering the AX us made by SeaSonic, I'd say they're pretty equal. I'd personally get a Snow silent from SeaSonic if all you care about is low noise.

Correct.  The Corsair AX850 has a better fan than the Seasonic version.

ah okay thank you, didnt know they were both made by seasonic.

Well this is probably my last build ever, so i am going to use it till it doesnt work anymore i guess. Also i know its pretty stupid but i still live at my parents so i'd rather pay more myself so they can save on the electricity bill

Also when Ryzen 4000 launches im selling my cpu to probably get a 4700x or better.

I really appreciate your math tho

Seasonic doesn't make all of their PSUs themselves, and the other points are not exclusive to them; rather they're common features of high end PSUs. Kinda weird and disadvantageous for you to willingly limit your choices like that.

They're a manufacturer...

They design and build their PSUs, unlike companies like corsair or EVGA that buy PSUs and rebrand them.

 

They also have the longest PSU warranties that exist, and also the best voltage regulation and other specifications, which you can see if you look at reviews.

Kinda weird and disadvantageous that you don't know much about the top quality PSU manufacturer in the world.

I really like my Seasonic GM-650 Semi Modular.  You can find this PSU for $99.

Well, not all of them. The S12III, ECO ST, SS-CT,  and S12II (other than Bronze GB) are manufactured by either RSY or SF.

Well, you could say "those are only budget PSUs" but that's not the point.

Where does it say those power supplies are not made by seasonic? Just curious.

Are they rebranded units or are they still designed by seasonic and had the assembly outsourced? Because those are two very different things.

 

Anyway I don't follow low end PSUs, I know that all of their midrange and high end units are completely designed in house.

This is really nice because it means the modular interface is the same across all of them so you can use the same custom sleeved cables even if you upgrade your PSU.

To be fair, not every company just "buys a PSU from an OEM and slaps a label on it."

 

Some of us have entire R&D and PE teams and have a 1 year dev cycle before putting the product on the market.

 

AX is the exception for Corsair.  Because Seasonic is so damn hard to work with.  The only thing we were able to accomplish with them is the use of our fan and our fan controller.  And even doing that had a good deal of push back from Seasonic.  Seems their engineers only want to work on new projects.  Not try to improve upon existing ones.

All of Corsair's PSUs, regardless of OEM, are the same pinout.

 

You're correct that's not true of everyone.  You have guys like Cooler Master and EVGA and Thermaltake that use "whatever modular interface the OEM has handy" and those will have different pinout from one PSU's OEM to another.

How come they sell different sets of modular cables for the HX series, AX series, etc?

Type 4 gen 4, type 4 gen 3, type 3 gen 2, AX series only, etc etc etc

"Generation" just means the sleeve material.  Also, there's no "gen 4".  You're making stuff up now.

 

Gen 3 is the paracord w/o heatshrink on the ends.   Gen 2 is the standard individual sleeve (nylon material?).  Gen 1 is your standard cable mesh sleeve.

 

Type 3 and Type 4 are the same except the 24-pin has the additional sense wires on it.  CX, CS-M, TX-M, RM, RMx, RMi, AX (Titanium) and AXi all have the same pinout.  HX has a different 24-pin because it's been around for seven years before the sense wires were added.

 

Completely different scenario that what you're trying to imply.

 

When you mention "AX" being different, you must be talking about the old AX and not the current one.  The old AX (Gold) actually used Seasonic's standard pinout at the time.  But if you want to talk ancient history, you can actually go back and find a number of Seasonic PSUs with different pinout.  Like Corsair, only the most current Seasonic have the same pinout across the board.  For example, the current Seasonic PCIe/CPU is an 8-pin.  But it used to be a 12-pin.  And before that, only a 6-pin.  The current Seasonics use a 6-pin for PATA/SATA.  But the M12 and M12II used an inline 5-pin.

Ah... My bad.  I lost track.

 

So Gen 1 is sleeved, Gen 2 is flat ribbon, Gen 3 is individually sleeved and Gen 4 is paracord.

 

Again... has NOTHING to do with pin out.

I guess you didn't make it past the first paragraph of my last post.   Let me copy and paste it here again since you missed it:

The AXi and RM are the older versions that aren't made anymore.  Wherever you saw that, it needs to be updated to specify which versions they are.

 

And the others you mention:  AXi, CX-M, HX, TX-M, goes to what I just said.  The Type 3/Type 4, other than the 24-pin, are the same.  So that line is basically saying, "Yep.  Fits all the Corsair PSUs."

I'll just leave this here :

http://www.orionpsudb.com/

And back to the OP's question.

1) These PSUs are nearly identical because this Corsair PSU is rebranded Seasonic PRIME Titanium. Aside of in-cable capacitors on Corsair so it's even somewhat better in ripple performance, but not enough to pay more for it, get cheapest, if you ever need a Titanium certified PSU in the first place ...

2) The chance that you'll ever need your PSU warranty past 8 years, not to mention 10 years is nearly zero so in this case 2 extra years for Seasonic doesn't change anything.

you're wrong in almost every way here

- Seasonic produces part of their lower end units at RSY, making them what you qualify as "rebranders"

- is Corsair's engineering division a joke to you? CV, CXM, CX, RM, RMx, RMi, HX, HXI(?), AX (kinda) and AXi all have custom platforms or customized parts on it because of them doing their work

- EVGA I'm unaware of if they have a team, but don't take straight platforms off the lines either all the time.

- Seasonic gets beaten out on voltage regulation in many cases because Prime is extremely stable, but at a higher voltage, making it technically worse than let's say an AXi

- Seasonic is a tier 3 manufacturer, someone like Delta, Flextronics, Liteon, TDK or alike would be able to smash them if they want to, and Flextronics has shown this with AXi being way ahead for years now

- warranty time is little relevant if everyone is offering 10+ years these days, with some exceptions

- then again, Jon already did his word with AX here, there's nothing outside of it for me to add

 

but that's just my two cents

Any recommendations?

If you're looking for silent, the Cosair AX unit is pretty much that. Get this one. 

 

Wattage wise, I'm guessing either unit may be way overkill for your system build.

Ever since my AX860i died and fried my PC I moved to Seasonic and I wouldn't change.

Obviously I only keep track of the higher end units, so if they outsource lower end stuff I don't actually care.

 

A customized platform is not the same as actually designing the AC DC convertersion and regulation in-house.

Changing the enclosure and some of the fan control is not the same level of control over the power delivery, if at all.

 

TDK, meanwell, etc. focus on industrial power supplies not consumer.

Even Delta is more OEM than retail.

 

Warranty tells you how confident the engineers are with their design and component selection.

Most manufacturers these days are far less than 10 years, even corsair only offers 10 years on their highest end units, idk why you think "everyone is 10+ years"
