Smaller poweradapter for P150HM?

Hey.

I happen to own a Clevo P150HM/Sager 8150 which we all know, I think, has a massive powersupply to deliver enough power for the demanding hardware. I realize that there's no magic that could just make a smaller powersupply that still could succesfully power the laptop at all times.

But if I keep the power usage low, for example forcing the GPU clock to be low, while I am at school or something like that, isn't it possible to use a weaker, but more compact, powersupply that can keep the computer going?

If this is possible, and if someone has some experience with it, could a specific powersupply perhaps be recommended?

Thanks,

 

So I had a look around.. Found out about this Cooler Master; USNA 120 - Cooler Master

Anyone have experience with it? Is it sufficient?

 

We always recommend using the OEM AC Adapters. However I do recall people saying they have used other ones with success. You may want to check out the owners lounge http://forum.notebookreview.com/sag...-sager-np8150-clevo-p150hm-owners-lounge.html, its pretty lengthy though and may take a while to find what your'e looking for.

Hopefully someone will post one that they have used.

 

contact htwingnut. he sometimes adapts the 240w slim aw power adapter for the sager. it is not necessarily small, but much smaller and more poerful than the stock unit.

 

I had a look around for the 240w power adapter from Dell. I can't really find it sold in my country (europe). And I guess htwingnut is american? Just gaming seems like it can run up in quite some money and time consuming, but the 240w, while being smaller, does seem like a cool power supply.

However, my gaming days are by and large over (atleast on a laptop). Therefore there wont be must intensive action going on, on the laptop, which is where Im thinking that a 120w might be enough? Gonna have to see how much power my p150hm (with a 6970M) consumes, ofcourse.

Thanks for your inputs.

EDIT: Also, what's the worse that can happen if usage goes over 120w? Will it all just fry or will it start draining the battery?

 

You need this: FORTRON 150W/19V NB ADAPTER Зарядни устройства
Its the same size as my OEM 120W adapter, but with 150W output.
Interchangeable tips. EU standart, sold in many shops in my country.

Ive been using it for more than a year now, its rock-solid.
Comes with a carrying pouch.

EDIT: its never a good idea to try and stress the power supply beyond these 150W.
The worst that can happen - the laptop starts using the battery and system slows down accordingly.
This can only happen if you load a heavy game during your "school session".
Same thing as if you are attempting to play StarCraft 2 on battery power - your framerates drop to 30 or less, turbo boost is disabled and your GPU downclocks to a minimum (cause the battery cant output enough power).
Thats what happened on my P150HM years ago when the power in my house shut down - the game became choppy and laggy.

EDIT-2: also, it would stress the power supply and lower its life expectancy if you stress it beyond its wattage limits. Technically, it *could* fail if it overheats beyond a certain point.
Power efficiency also drops the more you stress it. And the current is also harmful for the computer, as its frequency and specifications become unstable.
Just dont play heavy games while on a weaker power supply. Browsing is fine, watching movies is fine, playing solitaire is fine, even StarCraft Brood War is fine.

 

Great reply, thanks.

I had a look at this particular PSU as well, as it was recommended in one of the threads. Couldn't find it in my country but I can give it another go.

You say it's same size as your 120W. How big is that? Do you maybe have the weight of it too? I think the weight of my 180W for my P150HM is a bit above 1kg. The Cooler Master is 250g. That's a huge difference. But if this Fortron does the job better and is quite lighter as well, then I dont see a reason not to get it but I can't really find the specs on it. Maybe I'm just bad at searching...

About power usage. I wouldn't worry too much about it. I'll do alot of GPU clock-managing to keep the clock locked at a certain low, so power usage is minimum, etc, to avoid stressing the PSU.

1,5 lbs, bro.
or 0,68kg

EDIT: btw, thanks for the rep!

 

Thanks for your suggestion and input but I think a PSU like the Cooler Master would fullfill the point more. I mean, I am looking for a smaller PSU (as small as possible preferably) and the 150w one is not much lighter and psychically smaller, it seems.

It's not so much about delivering alot of power, I mean I dont overclock or anything like that...
