NP9150 Power Adapter

Hey guys! Would I be able to pull off using a 120w adapter on my 9150 with GTX 670mx and i7 3630qm?
When hooked up to my 180w adapter, Prime95 produced a peak of 160w, but then went down to around 120w.. And that's with everything at full bore.

Basically.. What's the physically smallest adapter I can use for this PC?

 

You may be able to swing it with the 670MX since the NP9130 has the same GPU and uses a 120W. I'd stick with 160W though unless you absolutely have to have a little bit smaller AC Adapter. I'd recommend not doing it as you're introducing risk if you do.

 

What kind of risk are you talking about?
I just hate having to shove this big clunky adapter into my bag

 

Under powering can sometimes be as bad as overpowering. I'll just say, dont do it

 

agree, dont do it. they are that big for a reason.

 

My 150em with 670mx came with Liteon 135w so you might be able to

 

It's almost impossible to get this big brick into my bag! I think I'm going to need to find a smaller adapter..
I've heard it said that they're big for a reason, but seriously, they can't stay that way forever!

 

you shoult get the dual gpu clevo next. its got 2 psu's

 

well, for travelling u could even pull off a 75-90w adapter, but only if u keep both ur cpu and gpu on idle clocks i myself am using a 120w adapter for work and i can use it with my cpu up to 3ghz on all cores while my gpu is manually forced to idle clocks. so its perfect for work tasks while still giving me a way smaller brick to carry around

Generally, you want the surplus watts. If your peak draw goes over the power supply's capabilities, you're gonna have a bad time. If you keep the clocks low as jaybee mentioned, then you're safe.

 

I use the Coolermaster USNA 120watt. And downclocked the Gpu in msi afterburner to the lowest settings. The power draw never went beyond 110watt in BF3 and Starcraft 2. I used a wattage meter to measure it.

 

Where'd you find the USNA?! I looked for one of those everywhere!!

 

Well.. Does anybody have any recommended adapters..? Preferably as small as possible..? I just got this Cooler Master NA120 in the mail today, but some of these posts are making me nervous.. Not sure it's worth the $2500 risk

 

well, as mentioned before,just keep ur wattage low and dont do any benches or gaming while on ur smaller adapter and u should be fine but u cant expect to use ur laptop in high performance mode.

Overpowering? You can hook up an 800W PSU to a 200W system with no issues since it should draw what it needs and no more.

 

Thanks for the help guys, really, really appreciate it.
Any suggestions on a good (smallest form-factor) charger though..?

 

Well a modified Dell alienware 240W slim brick soldered with the correct cable and the type that has no third hole in the PCB for the sensor pin is technically the best....

 

How hard would that be to do..? o_o

 

Very difficult since it requires sourcing a cable (or harvesting it from your current one) and doing some soldering.

 

Soo.. What about just a plain ole 180w adapter..? Any recommendations? I've read on other threads here about modding adapters and such but that's not worth the trouble for me.. I just want a freakin adapter that would fit my freakin laptop.. AHHHH

 

Bump..
Still seeking recommendation on a solid power adapter..

 

Any 5.5*2.5mm tip 180W should be fine from the likes of FSP or delta.

 

Thanks for all the help guys, namely Meaker!
Do you have an opinion on this one..?

AC Power Adapter - Sager 9150, NP9150, P150EM Laptop AC Power Adapter Charger

Looks good, but I don't want to get stuck with a lemon, or one that's twice the size of what I've already got!

 

Well I know RK sell genuine adapters.

 

Sorry.. RK?

 

rkcomputer, the forum rules prevent me from linking people.

 

Got it, thanks man! Appreciate all your help!

 

Not a problem, feel free to shop around however as they are not the cheapest place but I know you will get official supplies.

 

I got tired of the standard heavy brick that came with the P150HM so when it bit the dust via strain relief cracking, I decided to do something based some of the posts in this forum with the Dell PA9E supply:

I really did not like messing with the internals of the power supply so I did an external adapter that also incorporated a makeshift magsafe-like function. Here's a couple of pix:

hmmmmm.....running into issues with uploading pix either locally or via remote url... if anyone can help me sort this out, it'll be greatly appreciated...

 

u dont have enough posts yet to upload pics i guess your solution sounds interesting tho! would like to hear/see more.

let's see if I can post a link to the pix:

Wow, how did you do that..? Is it something I'd be able to do at home?
I'd be very interested in trying that! Or purchasing one from you... hahaha

 

Wow, if you are selling that kind of adapter I believe many of us are willing to purchase one. Super cool !!!

 

may i ask where u got that adapter? as far as i can see, u pretty much just swapped the cable leading from the PSU to the laptop and added an adapter to make it compatible with the DC-jack of ur machine, correct? thats quite brilliant i must say, and SO much less of a hassle than modding the internals

more info please!

 

Not exactly, it is a stock, unmodified Dell PA9E power supply. I actually built 2 adapter cables, I happen to like the right angle one better so I use that the majority of the time.

Here is a pix of the other adapter....
I got most of the parts from Rat Shat and a bit of soldering....



the break-away functionality has save my butt probably 7-8 times in the last 5 months.

The other major reason why I love this power supply is the weight and thinness factor which allows me to mount the PS on the back of my screen lid, saving me much physical space on those tiny cafe tables....



If there is enough of a demand for kits, I can be persuaded to do a run.

 

Count me in!

Lol, I'm no good when it comes to soldering stuff

 

oh hell yeah, i bet ull find lots of VERY interested customers right here on NBR best to open up ur own thread to get the attention this project deserves imho

 

Thanks for your kind words! I'm glad my hack is of interest to my fellow enthusiasts. That being said, I want to make sure reality does not get too distorted or worse yet, the spirit and letter of the rules here in the forums are violated by a previous lurker (that's me!)

Let me think about this. If any moderators or more veteran members want to throw advice my way to keep me on the right path, it would be greatly appreciated!

 

I believe creating a thread in the Market Place is the way to go

 

Not to add on any pressure, but yes, I would DEFINITELY be in! That looks like a very well made mod. Like some others, I'm not great at soldering :\
How many people do you estimate would make it worth it for you to start a build?

 

What gauge of wire are you using in the adapter? Does it heat at all when breaking 200-220W worth of draw?

 

Count me in, awesome little mod.

 

I can't be sure but I'm thinking they're at least a step up from the gauge used in the default Clevo supply (++gauge == thinner wires). I'm still using the 460 and I've gotten the fans at turbo mode when I do sketchup under wine without any noticeable difference in in temps between the main and the adapter wires.

 

There was someone else using an adapter over in the MSI section and it got hotter when going above 200W which is what the larger supplies are all about, did you make the adapter or did you get it from somewhere or a bit of both?

 

a bit of both in the sense that I took the right angled connector from a different, orphaned PS that I had laying around and a female tip that fit the Dell which I then soldered together.

That's why I can't really tell you specifically what gauge of wire it is.

 

I second that. Create a new thread and write a tutorial please

 

What I like about this method is not all Dell PSUs are wired the same internally, some have a weird feedback system and this all gets past that and should just work, a guide would be awesome, if you have the time.

 

The size and weight of your laptop and ac should have been a concern before deciding on buying a powerhouse of a laptop. You need the 180W if you want the system to run the best it can without the screen dimming or it not running as fast as it could.

On such a pricey machine, I wouldn't use anything other than a "Full Range AC-in 100~240V, 50~60Hz, 180W AC Adapter, DC output 19V, 9.47A" - Anything less you will be sacrificing performance taking away from the awesome machine that the NP9150 is.

 

The point is we are modifying or adapting a slim 240W dell that will be more than up to the task

 

I'm in too. This sounds AWESOME! Just create create a signup sheet, and then when you have enough people to do a run, let us know how much it we'll cost, and we'll order via PayPal.

Uh... This powerpack is way more powerful than the one comes with the NP9150...
