Corsair took a plunge into the world of high-end SFF gaming PC builds, with the SF line of fully-modular PSUs, built in the SFX form-factor. The company showed off its 600-Watt variant, which offers enough juice and straws for an SFF build with a high-end graphics card. It may use a tiny 80 mm fan to keep itself cool, but features a Zero-Noise mode that keeps it off under a load threshold. Corsair plans to launch a broader lineup of SF Series PSUs in 2016.

By looking at the image. SF600 looks long and half width of an SFX SPU.

If you want a small space, this defeats purpose of using SFX?



Then you can get the Silverstone SX600-G or slightly larger SX500-LG Posted on Jan 7th 2016, 19:09 Reply

The box image is deceiving, here is a better shot. It is the standard dimensions of a SFX PSU. Posted on Jan 7th 2016, 19:13 Reply

Any word on who the OEM is? Likely to be substantially more reliable than the SX600s? Posted on Jan 7th 2016, 21:46 Reply

GhostRyder About time we got more name brands of sfx psus. The choices were very limited before. Sure more choices are always good but already there is a pretty decent selection of SFX power supplies from Silverstone, Seasonic, FSP, and Enhance. Now I hope Antec and Coolermaster also start offering SFX PSU which will make selection choices even better.

Does it even matter what OEM it us underneath these days? All custom designs, regardless of OEM's tend to be superior to what OEM does for their own brand if they have any for the retail itself.



If custom design dictates what kind of components they have to use, it means even shitty OEM's can produce high quality PSU's. Because the vendor ordering this custom design wants such components. In the end, only manufacturing process dictates quality differences (like soldering quality/precision). Posted on Jan 8th 2016, 2:34 Reply

Corsair is gonna use all Japanese capacitors in these psu's. By that alone these corsair sfx offerings will be better than Silverstone's equivalent wattage offerings. I'm currently using a 450 watt Silverstone sfx and will be upgrading to this 600watt unit from corsair when it starts selling. Posted on Jan 8th 2016, 2:43 Reply

Frick This is also something that has changed. The Japanese cap thing is mostly for marketing. The capacitor plague is long behind us. I would never use a PSU with Chinese caps, Teapo (as Taiwanese) is slightly passable but I prefer 100% japcap PSUs. With high price comes high quality, and if PSU costs 100 euros or more, 100% japcap PSU is the only way to go (excluding polymers on modular connectors board, Chinese on those are passable).

Are Chinese capacitors really that worse? I'm pretty sure Chinese have a company that makes high end caps as well. Unless if they are like with cars. They just can't be bothered to make quality products. Posted on Jan 8th 2016, 5:53 Reply

RejZoR Are Chinese capacitors really that worse? I'm pretty sure Chinese have a company that makes high end caps as well. Unless if they are like with cars. They just can't be bothered to make quality products. 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.



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.



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? Teapo is "Chinese" in some respects but it's in Taiwan.

They just can't be bothered to make quality products. It's pretty hard to tell the quality of caps early on. The main reason for the entire mentality is the capacitor plauge, but again that was years ago now. There are crap caps sure, but chinese =! crap these days. One of looking at it is would PSU makers use them if they were prone to failure? No, at least not in products with a +5 year warranty. That would be just daft.

Semi-Retired Folder alucasa Hah, fire whoever came up with that awkwardly modelled PSU on the box! I don't think it is the fault of the box. It is just extremely hard to tell the scale of something when there is no reference point. Also there is the fact that the PSU is at an angle on the box, and then the picture of the box(which is clearly taken at CES and not a press shot) is also at a different angle. It just throws the perspective right out the window. I bet if you actually looked at the box straight on it would be fine. I don't think it is the fault of the box.

In the end, I buy quality PSU because life of all components depends on it and because it's not something I replace often. So it has to be reliable. I had Corsair HX750 (Silver rating) which was at the time of purchase top of the line model. There were models with higher wattage, but it was the highest end at the time (there were no AX models back then yet). Afaik.



Now I'm using Be Quiet Dark Power 11 Pro 750W (Platinum rating), again top of the line model with very reputable scores and incredible construction.



I had LCPower GP550W in the past and I was quite happy with it, but I didn't know better back then so I'm forgiven ;) Posted on Jan 8th 2016, 11:11 Reply

RejZoR Are Chinese capacitors really that worse? I'm pretty sure Chinese have a company that makes high end caps as well. Unless if they are like with cars. They just can't be bothered to make quality products. Of course they are not...



But you have to look at the datasheet and see how it is compared to the japanese one.

That a cap rated for 10000h should last longer than one rated for 2000h should be pretty obvious...



And japanese caps also fail, sooner or later. Seen some badly failed japanese caps (Nichicon or Rubycon) on badcaps a couple of days ago., SO even they fail...



Buttom line:

To say japanese caps are soo much better is just bullshitting!



Because the enviroment in wich the cap work is far more important than the quality of the cap!

If you design a product well, you don't need those 10k life caps...



Also the reputable Taiwanese and chinese Capmakers have also some long life series with 10kh lifetime.

Teapo has 4:

TA, TB, TC and (you guessed it) ST...

But you always have to look up the datasheet.



And the worst of all:

If a cap failed, you have to use your brain.

And think about WHY that cap failed.

Was it bad quality?

Or was it misused?!



Most of the time the caps were pretty much 'abused' and used in a high temperature enviroment, maybe high ripple also and to make it worse, they most of the time use the cheapest caps they can find from that company.

For Teapo that's clearly the SC series. It's the worst Teapo has...

And of course they fail earlier than a NCC KY - because the KY series has 5times the lifetime of a Teapo SC.
