Highest laptop power brick wattage?

My laptop power brick blew today and I need to replace it.

On the manufacturer's forum they say the OEM power supply doesn't provide enough power for demanding tasks.
When I did anything demanding my FPS would drop or the computer would lag, which could be a sign that I am drawing more current then the power supply can produce.

Now I'm looking for a higher wattage power brick to replace my recently deceased brick.

The OEM that died is a 19.5v 6.15amp.

What are the higher wattages that laptop power brick are available in?

You need to list what your laptop is.

The highest existing single laptop brick that I know of is 330W. But it doesn't mean it will fit in your computer.

 

MSI GT80 has a 350W brick.

 

It's actually 330W. Some sites reviewed it.

Unless some people say 350W and others say 330W, and nobody really knows. If it's a 350W, I want it. It has the same connector as mine.

 

It's a Lenovo Y580 and I'm OK with generic brand or universal bricks.
Current one is 120watt.
They mentioned (I think) 150watt was a good upgrade.

But I want to know how the Watt increment go. Like 90watt, 120watt, 150watt, etc.

xNotta, next one is 180W.

 

What could you possibly be doing on your Y580? No way a 3610QM/3630QM and single 660M maxes out a 120W brick.

 

You're probably right as that is what MSI reports. Dunno why some sites said 350W. -_-

We'll know for sure once it's reviewed and we get some pics of the brick's underside.

 

Got me.
The brick has been reaching 200F+ and has been melting plastic around it.
Looked into why it might be getting hot enough to boil water and found people reporting the charger was bring maxed.
It finally died today.

Any suggestions on a 19.5V 150W or 180w 5.5mm*2.5mm power supply?
I'm having a hard time finding one cheap.

The issue isn't one of finding one cheap now, it is finding one quickly.

Do yourself a favor and put your power supply on a notebook cooler before you start running it that hard/hot next time.

 

I just cut out a section of wire that didn't feel smooth and re connected the end to the brick and taped it up.

Multimeter started reading 19.5-19.8v, so now as long as I don't jiggle it too much, the brick works again

I actually had the brick sitting ontop of a fan at the end, tempted to add a fan to the case, but after this death, i think I'm going to be getting a new power supply.

What other laptops would use a 19.5V 150W or 180w 5.5mm*2.5mm?

Is it really not possible for the Y580 to be drawing more than 120W of power?

 

xNotta, ASUS does have 180W 5.5x2.5 PSUs. Make sure they have correct polarity and connector prior to ordering. It newer hurts to get a more powerful PSU than required - one of proper quality, of course - it will produce less heat and end up being more durable.

 

How do you check polarity? Just make sure the plug is a female type?
I know the positive is usually in the center and the negative is the outside of the plug tip, thought most laptops were like that?

Asus ADP-150NB brick seems affordable and matches all requirements at 150w.

 

This is the 120W brick you have right now: Lenovo 120W AC Adapter (19.5V 6.15A) UL | 57Y6549 | Lenovo | US

This is the 170W brick from the Y500/Y510p SLI which also works for the Y580: IdeaPad 170W AC Adapter (UL) | 888014240 | Lenovo | US

These are the safest bets since they are officially compatible with your laptop. You may be able to get them cheaper from elsewhere if you look around.

I don't think it's possible to make the Y580 draw more than 120W short of running FurMark on an absolutely insanely overclocked and overvolted GPU while simultaneously cooking the CPU (with unlocked power limits) using Linpack w/AVX. But by then the entire laptop would've already gone up in a ball of flames.

Just get another 120W brick, same as you had, if I were you. It's obvious your old one was defective. It's not normal for it to get so hot. I have the same 120W brick (in addition to the 170W one) and even when it's being maxed out by my Y500 SLI so that it's actually drawing from battery, it does not get hot enough to melt the plastic.

 

Ok, the brick is now emitting high pitched squeals and no longer works.
Got temp again and was only 120f from just Firefox running.

Will that Asus I posted earlier work?

Would a power short cause similar overheating behavior?
If so, how to be sure the problem is in the power supply, and not something in the laptop, such as an intermittent short in the power connector, or the battery or battery charging circuit?
For the battery, maybe could remove the battery and see if power supply still overheats?
But not all components can be easily removed.

 

to be honest with you i would go with the 170W charger octiceps suggested. i used to have an asus ROG 750JM and the charger was a 180w @9amps, i never noticed it get hot or make any noise but again i would first go with the lenovo charger.

 

I used a multimeter to test the AC cable then the DC end that goes into the laptop.
The laptop plug read 0v when it wasn't working.
When I brought it back earlier it was reading the 19.5v it should have.
The problem seems to be in the brick only.

There is a documented report of the y580 hitting 162w.

So, get a Lenovo 120/130w or the Asus 150w? Both are about equal in price.

The question is how high is your GPU overclocked (his 660M was 1200/6000 @ 1.1V) and are you doing anything remotely as demanding as Prime95 + FurMark. Assuming 85% PSU efficiency, 162W from the wall would be 138W from the brick, so a 150W one is fine. If you're a heavy overclocker who plays games heavy on both CPU and GPU, e.g Crysis 3, I'd get the 170W Lenovo adapter.

 

Only OC I've done was a modded bios that did "1000MHz default 3d clocks" and Lenovo dynamic graphics power profile and unparked cores while gaming.
I reverted bios when heat became an issue.

The 170w is out, too expensive($60).
The Asus 150w and the Lenovo 120w are around $20.
Of those 2, which would be better?

Get the ASUS 150W. Make sure it's the official one and not some cheap knock-off that'll catch on fire or melt (again).

 

Thank you!
Ordered!
Sold by Amazon, so should be authentic or it gets returned.
Thank you again opticeps and everyone else who helped me out.
