Im hoping to get an ASUS branded 180w-200w Adapter...I saw one for the G70 but I dont know if its going to be compatible with the G73SW...

If there are no ASUS brandaed what other brands are good that will actualy hold the
180w to 200w output?

why do you want a bigger ac? the 150w that comes with it works flawlessly. the only thing i would change is a L shaped plug

Oh yes it works fine but under realy heavy load specially when playing in stereoscopic 3D...My wattage meter always max's out at 150W and seems like it wants to go higher...but I dont have extra juice...I just want that extra wattage just incase I needed it...

Seems like it wants to go higher? LOL! Oh it will go higher if more current is drawn.

What that does to the power supply is another story, but generally they are made to handle short-term loads above their rated max.

These are load ratings, not output ratings. The machine is going to draw more juice if it needs it. A higher wattage rated power supply will be able to handle that draw, but doesn't provide more juice.

At the very least the larger power supply will run cooler.

I just ordered this, a little higher than Chastity's price, but at least it's brand new.

I might get this too even though I just ordered the L adapter...Playing Games at max setting realy heats up the stock 150w brick...and actualy eating up 150w max most of the time...Id rather have extra headroom...

Question though...

The power brick that came with my ASUS G73SW-3DE is a 19.5 volt 7.7 amps

The ones you guys posted has a 19 volt

I like the extra amps but does going from a 19.5 volt down to a 19 volt be an issue?

Electronics actually have a bit of play in them when it comes to voltage. Reading the output of a 12v line on a PSU for example will show 11.4-12.6v in a healthy desktop PSU. If we assume a similar tolerance of 5% on the original 19.5v then a 19v output within a tolerance of 2.5% will still be within the same range. Basically a *good* 19v PSU should be adequate.

Furthermore, voltage fluctuations are highest when the PSU approaches it's maximum output. Since you are using an over sized PSU the voltage fluctuations should be minimal, hence the voltage will likely be very similar to the OEM PSU under load.

what do you think about these...

180W ASUS

230W ASUS

Do you think they work with the G73SW's?

The electrical characteristics are within range but I've no idea on plug compatibility and there aren't any measurements listed as far as I can see. You'd have to find someone who has a G70 and a G73 to compare the connectors for you unless you're lucky enough that someone here just happens to know.

Yeah i was looking online at the G70 pics and the W90...the port on the laptops look different so i guess ill just stick with the Lite-on or Targus 180w just a safe bet...

Hey just found out the the Targus and Lite-On 180w AC adapter are actualy one and the same...Got the Lite-On one...

Lite-On and Delta are two major, and somewhat decent, OEMs of laptop PSUs, the real names behind a lot of the rebranding :)

So they are not that good? These are the only brands that I could get though...

Every search I do I always just end up with the Targus and Lite-On...which is actualy just the same AC adapter...

Not at all. He's just confirming that yes many of the brands are actually the same.

Just recieved mine yesterday...I noticed my voltages using HWinfo32 dont fluctuate as much anymore as with the Stock AC adapter specialy on load...I did notice something though. The connection to the power port is somewhat loose not necessarily a bad thing...but is this the same for you guys?

It's a little loose with the Yellow plug, but OK with the black one with 1 ring.

Hmm with mine its fine with the yellow plug...but i dont get power...i get power with the black one but its not a snug fit...its kina like how macbooks are...its good to know that it will come of when someone trips...i guess ill just have to get used ti it...

I have a g73jh A-1. My kids broke the original adapter and then I bought a replacement PWR brand off ebay. After a year and a half it has fried. I didn't know they squeaked. I was wondering if this 180W that was linked a few posts up will work for my model as well?
