Corsair recalls SF series platinum psus over failure problems

Corsair has discovered a potential problem with its SF series of Platinum-certified SFX power supplies that can lead to premature failure when the unit is exposed to high temperatures and high humidity. The problem isn't just limited to units inside U.S. soil as foreign retailers, such as Tiyu, Ask Corporation and Links International, have issued a recall on imported SF units as well.

Quote

Corsair's investigation revealed that SF units with a lot code between 194448xx to 201148xx, manufactured between October 2019 and March 2020, can potentially fail. Customers who purchased their SF power supplies before October shouldn't be impacted.

Quote

Apparently it's a technical issue that can manifest itself either when you turn the power supply on for the first time, or over a period of use. If you own one of Corsair's SF power supplies or just recently purchased one, you should give the packaging or sticker a quick look to make sure you didn't get one from the bad batch.

Fortunately, the defect resides in the primary section of the power supply. Corsair has reassured its customers that the fault isn't in any way related to the DC section of the unit, meaning the power supply might fizzle, but it won't take your components with it.

The problem comes from an impurity in the insulator pads used between the PFC diode and the heatsink. When subjected to moisture (e.g. humidity), the impurties crystallize and once harden again when used in normal humidity environments, causes the insulator to crack and tear. Once the insulator cracks, the diode touches the heatsink and it pops.

Good to see corsair is taking this seriously and defects happen. If you have a SF psu check if its part of the bad batch.

It's almost impossible to buy an SF PSU from Amazon or Newegg at MSRP right now...

That price reminds me of the mining craze where PSUs, GPUs and RAM were as expensive as two kidneys each. I was planning on a 7900x build at the time, and bought the PSU in my current rig then. I paid about 250 USD for it, only to not ever build that x299 system. But at least it came in handy when I built my current setup. Silly me, shoulda waited P:

Corsair will replace the unit free of cost and even take care of the shipping fees.

Solid support.

do you know how huge greatwall is? as they recently got back into production by the looks of it, this shouldn't be a problem for Corsair unless they got too many restrictions on shipping

more than that, even... greatwall just does TXM/SF/CX gray/CSM (eol) for them

 

for the modern line

  • VS/CV: HEC/Compucase
  • CX/CXM/RM/RMx/RMi/HX/HXi: CWT
  • TXM/SF/CX: Greatwall

how so?

 

and if that was true... Greatwall has hunters, HEC has Cougar and Flextronics has their server business. CWT I haven't seen retail of

 

also, this might be very worthy to add, a statement by @jonnyGURU

The problem isn't production capacity.

 

The problem is shipping.

...why?... Because of the Focus models? That's just one platform. SS alongside Delta, Super Flower and others are very good OEMs and, typically, very good places to source a power supply platform.

SS and Superflower along side Delta?!?  LOLOLLOLLOLLL!!!!

 

Anyhoo...  SS and Superflower can't do the power density that Great Wall can.  The only one that even comes close is Enhance, but the performance isn't as good.

I was under the impression that Delta have some high quality units (at least the server stuff I have access to is pretty solid)

Yes.  Delta does.

 

Delta is a tier one.  That's why you shouldn't put the likes of Seasonic and Superflower, who don't even have their own SMT lines, in the same category.

Lucky me. I have three of them. One 600 gold, which is fine. And two 750 platinum. None is in the lot code.

let alone that Delta employs over 83.000 people in total, while Superflower (only has 1 production line afaik), Seasonic (51-200 according to their linkedin), CWT (18.000) and Greatwall (15.000) combined have less (and technically CWT and GW are possibly higher tiers than Seasonic/SF as well, but I can only confirm of the latter two being "tier 3")

@5x5

I'm pretty sure that Great Wall number is quite low.  The "about me" statement on their website that says "15,000" is from 2009.

 

Delta is so huge because of the multitude of power devices they make.  That 83,000 people includes folks working on adapters, solar panels, power storage systems, fans/cooling, robotics, touch panels, etc.  They're HUGE.

 

Great Wall is in a similar situation.  They make a lot more than just SMPS.

 

The CWT number might be low too.  Their website is current enough to show the Vietnam raw materials factory, but they're now building complete PSUs there too and you don't see that on their website.
