Cooler Master Intros USNA95 Notebook and Consumer Electronics Power Supply

[btarunr]

Cooler Master released the USNA95, which stands for universal slim notebook adapter 95W. This is a compact notebook power brick that comes with a wide range of compatibility to most notebooks in the market, packing 9 manufacturer-specific DC connectors. The unit measures 104 x 62 x 17 mm. Apart from running/charging notebooks, USNA95 can also power USB-charged devices such as PMPs, mobile phones, and Sony PSP. Functionality aside, the USNA95 bagged this year's iF product design award. Backed by a 3-year warranty, Cooler Master's USNA95 will be available soon for around 65 EUR.

if i remember correctly....LITE-ON has a similar product to this but their power brick is a little more chunky - asside from it being slimmer then the average power brick. whats so special about it that it deserves an award? they are not the first people to use USB ports on power bricks.

design award!!

I'm going to make a yellow, banana shaped power brick. I'm expecting a design award as well.

design award!!

Design fail i think. Lets face it it has to have some crappy transformer in it looking at the shape of it. But lets face it a lot of people will believe what they are told lol.

For the same kind of price you could get a better FSP one.

first of all a slim notebook powersupply is nice and 95W is good too if it scales well.

i think that with some knowledge here anyone can see that this is not too good at EMI emissions as it fails to have a grounded plug, an absolute must have for me when it comes to high switching power supplys
And yes i know that theres a trick to "create" ground but that doesn't help with emi.

you can safely say that it rectifies the AC and charges a capacitor in its primary part and then uses stepdown regulators with high efficency to create the desired voltage in secondary and even with good input filtering none of that can lower their radiation while switching.(magnet and electric field around).

there is enought space for those "special" 3 plug style laptop cables thus it is more a design fail to go with the current 2 plug only.

i would like to see this in an aluminium case which radiates heat better and with some groundplug it would be versatile as hell...

OT:
Electromagnetic interference or EMI is an electrical disturbance (interference or noise) in a system due to natural phenomena, low-frequency waves from electromechanical devices or high-frequency waves from ICs and other electronic devices.

@Asrock: None of these should have a transformer, todays copper price, performance and weight would be no good. You might confuse it with their little transformers used to filter the ac input which are used more as a coil than a transfomer and size doesn't matter there it is more a way of design and experience as it way complicated.

these design awards must be given away like ugly kittens if they won a design award for something so bloody straight forward n simple as this. like i said. they weren't even the first people to have usb ports on their brick why should they win an award for stealing other peoples ideas?

I bet it don't maintain that 95 amp draw for long before it cooks itself trying to charge big notebook battery's.

Who the hell gives design awards to power bricks anyway if anyone should get one it should be apple with there awesome MagSafe connections at least there's some innovation there, i don't like apple but i cant deny some of there designs are quite good.

First review already posted.

It does what it says and well, not much to go wrong with a power adapter from a well known company like Cooler Master.

>Output range 18-20Vdc

Well, I guess it won't power my laptop.

You guys might want to read up on how the German iF awards work, you have to pay them money when you "apply" to compete for one of their awards and then the iF "grants" one product in each category an award based on some criteria's. So yeah, getting design awards isn't free and it's up to the company that made the product to submit them for judging and as such you can't really have a go at CM for getting an award their competitors didn't supply their products for, right?

 

[FreedomEclipse]

what sort a scam is this?? you have to pay some geeks to 'review' your product, rate & award it if it scores high enough? so the world can see you have a good product?? excuse me while i jump up n down for joy like a crazed lunatic. big f**king whoop. if it is a good product - it wont NEED an award for people to go out n buy it. product awards mean nothing if you have to pay for it.

Could say that they payed out of pocket for it and have to charge more for it too. So in the end you actually get less not more. Little sticker means crap to me well except a price hike.
