Corsair Shows Off SF Line of SFX PSUs

[Diverge]

It's been over 6 months since that jonnygurru thread, is it common to change the OEM from sample period to retail?

I'm just curious if oem then is still the current oem.

Teapo is "Chinese" in some respects but it's in Taiwan. Teapo basically isn't a big deal anymore. The caps coming from the mainland are, unfortunately, as garbage as they were before.

So you're basically saying that all caps used in chinese made components are crap?
Because those caps are made in china due to import tolls...

Teapo is about as low as one might want to go in an SFX PSU. Remember the SX600-G's Suscons? This is a very compact form factor where caps probably have to stand up to a lot of heat with that puny fan.

I disagree
Because Su'scon has some interesting capacitors (those anhydrous ones). Though the ESR value of those is shit.
And that's the 'problem' with those caps:
You can't rate caps by the manufacturer.
You have to take a look at the specification of that particular capacitor...

Chemicons and Rubycons don't make or break a PSU's performance, but when the PSU isn't cheap to begin with, why not have them?

See that Jonnyguru Thread, where I asked if someone would prefer the Nichicon UPS series over Teapo SC.
Both have similar lifetime. But the Teapo SCs have a higher ripple current and about half the ESR of the UPS series...

The capacitor plague was caused by copying down a formula wrong.

That's what's said in the deeps of the interweb.
But I totally disagree with that. IMO that's just bullshit.
The point is just that the water based electrolyte for those low ESR caps was as new as it gets.
And some manufacturers fucked it up more than others...

And here comes the stolen formula into the pictures:
If someone stole that and someone used them (wrongly, of course) than no one is to blame.
And that's all there is to it to this legend.
Would be bad if someone has to say: Sorry guys, but we fucked something miserably up...

OW has only stopped deducting for Teapo caps, because Teapo caps are fine. The likes of Suscon and Fuhjyyu are not off the hook and they really should not be.

Every Su'scon?
Because they have like 8 different low impedance series...
From the lower cost SD series to the little bit better MC series, to the long life series MG and HG.
As well as Those three letter series with the N at the end. Like SDN, HGN....

It's common to just loosely specify the capacitor model and make to not get problems if one of the capacitor manufacturer you specified isn't able to make enough so that you can also get some.

For that case it's not a bad idea to have a second source...

@Stefan Payne

With such a bad reputation as that of Suscon and Fuhjyyu, do you think that OEMs will get around to using their top-of-the-line "anhydrous" caps? Do you really think that they have any obligation to live up to what they "claim"? They aren't North American or European companies.

When OEMs resort to caps like those, they aren't trying to use quality products. They use those brands to save money, and quirky "anhydrous" caps don't save them money. These have 0 marketability.

All this would have been interesting if it made any financial sense. That's like Toyota making a luxury sedan that sells for $100,000 base trim. It doesn't work that way because that's not what most people are looking for from Toyota, and Toyota doesn't make luxury cars; people would buy Lexus for that.

Yeah, Teapo has some great lines and so do Taicon. These two have basically elevated to near-Japanese quality or the same in reviewers' eyes. Third-tier cap companies have yet to prove their worth.

As far as I'm concerned, the biggest possible problem with Corsair's new SFX venture is the semi-fanless mode. They make it sound like 92mm moves something like twice the air of the 80mm; it's still a SFX PSU with all components jam-packed inside on the PCB. The SX600-G was scorned by OW because of the use of crapacitors in addition with the semi-fanless mode.

The OEM for this unit is still Great Wall. The first units will be shipped with the Bulldog program and the retail units (stand alone PSU) will likely be available in certain channels by early March.

Also C(r)apxon is one of the (in)famous cap manufacturers which I don't trust at all. I don't mind if there are som Crapxon polymers in a modular PSU's modular connector board, but electrolytics are absolutely no-no for me.

First, that picture is super misleading. Thank you @newtekie1 .

Second, nice to have more SFX PSUs out there. My SFF cases uses FlexATX from Silverstone. Another standard for SFF enclosures that doesn't get much love, apart from Fortron/FSP and Silverstone.

EVGA Hadron Air uses 1U PSU, which is a variation of FlexATX, but with slight dimensions and mounting holes difference. They have the only gold rated 500W , 1U PSU in the world it seems.

Apparently there isn't a single winner in SFF PSU solutions for now. Intel gave a push to FlexATX in 2007. by legitimizing it as a standard, but apart from HP, Shuttle etc. industrial/ server stuff, it didn't fly much in home PCs.

So glad more options coming to this size range. Still waiting off a bit before I get parts for my Compact Splash case.

Nice Corsair , SFX be the format of the future..

 

[Ferrum Master]

Nichion, Panasonic, Nippon chemi... the only ones I trust and use for electrolythics... all china caps are still crap - case closed, each time I buy them due to emergency shortage of parts and measure, they worse than rated by the datasheet, and they fail faster than the rated times based on the type.

Small supplies are indeed not common. At least some competition.

Wow -It's tiny! And awesome!

I used an SFX psu (silverstone) in a small case (not SFF just a smaller case), and the space it saved makes working with anything inside the case so much easier.
