High Performance low power PSUs

Will HEC produce Cougar CM PSUs in the 300-400w range?

There are alot of people who are runnig lowpower setups that still wants nice PSUs with modular designs and 80 plus certification for even lower noise.

I also would like to see a little more modern setup on the native connectors on the PSUs. Peripheral connectors are not neccessary at all imho but sata connectors are today. Floppy connectors should also only be available through modular cables.

A 300 watts 80+ modular PSU with a quiet 12 cm fan would be realy nice. I would buy it in a heartbeat.

Hi!

We have.
Have a look on this model: http://www.prisjakt.nu/produkt.php?p=452202
It is the TE-series which is 80 Plus certified.
The actual COUGAR 400-700W series is based on this TE-series but in COUGAR PSU the components are the best possible.
For 400W you can take this one here: http://www.prisjakt.nu/produkt.php?p=451978
That´s the new COUGAR POWER 400, 80Plus Bronze certified, up to 88% efficiency

Maybe there will be a 300W model with 80 Plus Bronze at the end of the year, not sure.

A 300W modular PSU we will not do. Too less connector for such a model. Also the CM module will increase the price and in 300W-400W market every USD counts.

By the way - you like efficinet PSU but not 1kW and more - here is the world first 550W PSU with Silver certifaction. In Germany soon available in around one month in Scandinavia too.

Huh, that´s the first time we announce this, on Monday next week the press release will be out, so far it is not announced officially. hmm, ok, now it is.

We still think that some MOLEX (periphal connectors) are necessary. These connectors are allrounder. You can use them (still) for ODD, HDD, UV-lamps, watercooling parts, fans, etc.
SATA you ONLY use for drives so far.

And - you can use simple MOLEX to SATA Adapter to use the MOLEX ones as SATA ones.
But SATA to MOLEX Adapter is difficult to find.

Our Floppy Connector soon will be taken off from all COUGAR PSU. We will put a MOLEX to Floppy Adapter in the package.

The COUGAR CM 700 already coming with this solution, soon all other models.

Well, I think your marketingpeople are wrong in that assumption.

Make one, send it over to silentpcreview together with a nice (µATX) case and make them build a lowpower setup, for example a AMD 785G based motherboard and 45W cpu and you'll create a market for such a PSU and making Cougar _the_ PSU for a sexy lowpower HTPC. And I'm sure you can make it affordable even with modular design.

Its nice to hear that at least the floppy connectors is to be removed. But atleast on the lower speced PSU, please take away the molex too and have them only modular.

If I want to make a nice fileserver tomorrow I might think about the Cougar S 550 but I still dont have the need for molex then. Please Anyway sounds like a really nice PSU and Im glad you could break the news for us.

Sorry missed out that the Cougar S already had the molex as modular.

That looks like a nice product, except for the color...

I would also like such PSU. However, I've heard that the price of manufacturing such high quality lower power PSU in the 300W range is not much different from a high power version. There is no linear relationship between output power and cost of manufacturing.

The problem with modular connectors are that they usually decrease the efficiency a little bit, which in practice can be the difference between passing as 80 Plus Bronze or 80 Plus Silver (or Silver instead of Gold). I think the SPCR crowd would prefer the Silver certified one over the Bronze, despite the lack of modular cables. But maybe I’m wrong.

I would like to read Compusecase/Christian Verfuerths view on this

Hi!

Well, I think your marketingpeople are wrong in that assumption.

First of all, I am not a marketing manager purely, as Product manager I also work together with our R&D department to develope new products and to make our products better, also in a technically way.

The problems are price and market.
The market would be too small for it because the CM module costs money and the modulare cables are also more expensive.
Then you have for example 8 PSU, all 300W, all 80 Plus Bronze, all with same connectors, all very similar price, also from good brands. let´s say 40 Euro. then we have this model with CM, all the rest the same. But ours costs 45 Euro. Why should they spend 5 Euro more for a PSU with maybe 3x sata, 1x molex, standard 24 pin plus 4+4 pin and one 6 pin connector when they all nearly use all connector for a HTPC?

And what i wrote before in some other thread here again:
"the point is - we are too big to try products for a small market. We have to take care that our production always is 100% economically organized. Producing products in smaller quantity means that we have to stop a production line and change the mouldings, components etc. etc. to start a production of a new product. then we produced 200 pieces in 30 min and then again the production line will stop and we need another 60 min to change the necessary things for the next product. and so on. Then we have only 2 hours production of products in 6 hours of time. Not good."

Modular only makes sense when you have higher output because of lots of possible connections.

PERFECT explanation.
The difference from 300W to 400W when you use same quality components is max. 1 USD. Only because of more connectors and cables the 400W version is more expensive, but the PSU itself is nearly same price.

Also correct. But it will not decrease the efficiency of 1% or something, it is maybe 0.2 to 0.4%. But it can make the difference, yes.
All of our PSU reach higher efficiency as the 80 Plus Logo shows. In some reviews our Bronze CM 700 was more efficient than some other brand model with silver logo.
And . modular cable system are just another connector between the PSU and the component. If you don´t create a 100% perfect system, you will have another point where you will get defective PSU´s back.
the better PSU is the one without CM.

Still think that you underestimate the demand for such a product and the customers willingness to pay an extra 5€ for the ability to have a really clean case. Anyway, many thanks for your response.

That looks like a nice psu, but why only one PCI-e connector? Because i think that PSU without problem could manage a GPU that have the requirements for 2 PCI-e 6pin. (Maybe not the recommended settings but anyway).

@laggarbacken
You are right, only one 6-Pin PCI-E is too less. We will change to two connector ASAP, should be done in around 2 month.
We concentrated so much on the main points, the internal components etc. that we made a small mistake here.
At least, this kind of mistake is easy to repair and no damage will be caused
