    I'm interested in buying a targus 180w universal psu. It is rated at 19v 9.5a, will it work with my laptop that is rated at 20v 6a?

    The reason for me buying it is due to my laptop freezing and screen turning off when running heavy applications such as starcraft 2. I constantly clean out the dust and replace thermal paste often so I don't believe it's an overheat issue.

    No I wouldn't buy it.The voltage has to be exact.The ampere can be more(not less) as the notebook draws only as much as it needs.But the voltage has to be exact.Try to find auniversal adapter that goes up to 20 Volts.

    I'm not sure if my laptop has variable voltage, is there a way to check? Were only talking 1v, I thought laptops can handle that?

    You can't be 100% sure that it will. My Everex XT5000T was the same [email protected] on the original addapter but the Targus 180w worked without a issue. I purchased it knowing I may have an issue but the gamble worked out fine for me.

    So basically there is a possibility of burning out the psu? Would the laptop be in danger or would it just become unstable?

    The possibilities of problems is endless. The only way to be sure is to find a bigger brick for the box you have, such as when there is a version that requires a higher amp draw. From that you are left with the aftermarket and the best you can do is match capacities. Voltage you want spot on as in if it 20 volts you want a 20 volt addapter. Amps can always be a bit higher.

    You dont want to go too high though. The breakdown to core voltage, usb voltage etc, aka rails, is done on the laptop power board side. If you pump too much into the power board it may try and output to add-ons etc more power than the board is truely capable of. This is an invite to a real disaster.

    With the P7805u I am running a X9100 and when I push it too 3.7 GHz and overclock my Video card too I can tell I am really pushing the power board near the edge but the brick is just blowing it off like it is not that demanding. I could easily see accidentally overloading the power board..................
