    I read about this (USNA 120 - Cooler Master - Leading Provider of Computer Case | Cooler | Power Supply) late last year, but I haven't seen it widely available.

    Does anyone know what happened to it? I bought the USNA 95 for my girlfriend, and it seems to work admirably--though hers is just a Sager NP5160 and nothing incredibly power-hungry.

    Also, does anyone know comparable notebook AC adapters? As silly as it might look, I wouldn't mind a 150W AC adapter the size of a sheet of paper (But thicker, obviously.), as long as it fit nicely inside a bag instead of sticking out like a... brick.

    I read for it long time ago as well, but it wasn't available until couple of months ago. Got it, looks good, it's pretty cool while doing its job and it's half as thick as the OEM Acer that I bought and used like 2 hours then forgot about.

    this is very interesting. the specs say it provides [18 - 20Vdc / 19Vdc 5.79A], so i'm assuming its output power is 19V*5.79A=110W. (plus, 5V*2A=10W for its two USB ports leads to the total output power of 120W.) however, my SONY adapter has to output a 19.5V signal to the laptop's motherboard. and my question is whether this adapter is able to provide a constant 19.5V signal to my laptop (considering that a 19.5V signal lies in the range 18V-20V mentioned above)? the web page also says "it delivers output power at 19Vdc", which makes me worried that it's really designed to output a constant 19V signal and not a 19.5V signal. any tips?

    Sorry I can't help you with this one. BTW the USBs have different output - USB1 - 2,1A and USB2 - 1A.

    Well, compare its specifications to the one on your current AC adapter. My current one only says 19V. I actually have a few AC adapters available that I could look at when I get back home after the weekend. My house has a few Sager and ASUS laptops, and we can all use each others' AP adapters interchangeably, aside from one 90W adapter.

    I'll tell you what voltage ranges mine are, and maybe that'll help clarify.

    ^ thanks :)
    yeah, that's what i did. my current SONY adapter says it provides a 19.5V output. the CoolerMaster adapter, however, says its output voltage range is 18V-20V (so my 19.5V definitely lies in there). i just wanted to confirm that it can actually output a constant 19.5V.

    (PS: and how does it know how to output such a signal, btw?)

    well, the picture below (right) shows that the output voltage is 19V for USNA 120. i guess it's not compatible with my laptop then.
