So I touched my laptop's charger, and holy ****, it's hot as hell. o_O; I mean, I can still touch it without getting burns, but it's really damn hot. :S Is this normal?

Yes it's normal. When I got mine I was worry about the same thing, but the vendor told me it's normal and you will see that it will get hotter when playing games.

Mmmm, that's probably why - I was playing Civilization V and it started heating up. Speaking of which, I was wondering if I was the only one who was having a bit of a performance issue with that game. :S According to my laptop's specs (check my signature), I should be able to run Civ V without any problems.

@AdelaisAer for performance issues You should look at any of these 2 threads as it is probably throttling, as soon as I installed ThrottleStop all went smooth under heavy usage while playing WoW.

For the overheating issue, you should check this post from Chastity@ASUS in case you want to get for a bigger charger.

If I use throttlestop will my G74 get damaged quickly/ overheat or do I have nothing to worry about?

Yes. You are advised to upgrade to a 180W AC adapter. Iunno if 120W will work as well. :S All I know is that 180W is the recommended one. I am having trouble finding a universal one that'll work on G74SX *AND* is sold within Canada, Amazon/eBay/Tigerdirect included.

Unless you don't use your G74 at high loads, I would not use a 120W power supply on the G74. A quick survey of G74 component power ratings shows the minimum wattage that the G74 needs at "full throttle":

Core i7 2630QM/2670QM Processor TDP (max)= 45W
NVIDIA GTX 560M (max) = 75W
Chimei Innolux 17.3 LED (N173HGE-L11/L21) = 9.3W
Seagate Momentus 7200.4 500GB 7200RPM (x 2) = 3.1W each x 2 = 6.2W
Intel HM65 Chipset TDP = 3.9W

Total ~ 140W. This doesn't even account for the power required by the motherboard! In desktops you always bank on another 75W for just the motherboard (when you're buying a PSU for example), but since the G74's is smaller it'll probably be closer to half that, say 35W. So thats 175 watts right there, that you're already trying to pull from the stock 150W supply. It gets very hot because 1) you're pulling near its maximum capacity, and 2) the low and high end of a power supply's capacity is where efficiency is smallest, and therefore more wattage from the wall is converted into heat.

Go with a 180W unless you travel: stick with the 150W then. A 120W supply would be run over-capacity by alot, it would fail faster, plus it would be horribly inefficient and make more heat than even your 150W!

Exactly. The AC Adapter that comes standard with the G74SX is definitely less than that. I can't tell how many Watts it is because mine doesn't say. :S Just says volts and amps, but not Watts. But regardless, I can tell that I need to upgrade to the 180.

I like playing games (duh, it's a gaming laptop) and I really need to get a 180W AC Adapter. But I can't find any that are sold within Canada, or on Amazon Canada or whatever. :S And the only 180W that the Asus eStore has is not compatible with the G74SX (FOR WHATEVER REASON).

What about this PSU... I think this PSU has enough Power to drive even a G55sx.

AdelaisAer check the link, I'm not from Canada but I checked on Amazon CA and found the one that Chastity recommends.

btw.

I ordered a Lite-On PSU for my VX7SX and today i did following modification. I used a Papst Fan with 24 volt. I also had to drill 4 hole an each side of Case in oder to feed the Fan. I also drilled the metal (CoolingPlate) inside the case.

I tried Battlefield 3 around 3 Hours and the Psu got warm, but not so insane hot as before.

Have a nice Day
Stefan

i forgot. the next days a have to do a litte modification to make the Fan quieter.

Hmm, I see. It doesn't say that it officially supports G74SX, but I guess if Chastity uses it, then I guess it still works, right?

... but i think if you want a longlasting PSU you had to do that. I believe even getting a PSU with 180, 240 or 330 Watt will not eliminate the Heat these PSU produce. These devices will produce less heat than a 150 Watt unit.... but enough to be sceptical.

They have AC adapters for laptops that can go 330W? o_O; Is that even safe for a laptop?

I am not sure... a higher rated PSU (180, 240, 330) is saver than a uncooled 150 Watt unit.... i Hope :o)

i bought 2 240w units today... at ebay. for only 50 Euro each. Second hand.

until these arrive I use my cooled version...


btw. i owe 2 additional Lite-On PSU.... these two died because of overheating ( I think with these exteme temperatures the components of a PSU will solder out themselfs.. and therefore cause many problems)

I see. Because the stock one that comes with the G74SX is 150W (I THINK...), but either way, it's unsafe supposedly, so I wanted to upgrade to the 180W one and then use ThrottleStop in order to use my CPU and whatnot to its full potential (because of certain games and the G74SX's CPU being idiotic).

this is what i think too. I don`t understand why asus is supplying such underated PSU with their flagships.

Good night. :o)

Well, I'll go with the 180W one, since apparently that's more than good enough, and a higher rating isn't really needed. :S

Are u sure that will support the g74? Seems kinda crazy a 330w PSU!!!

That definitely won't fit the G74SX...unless it has the same dimensions port as that of the Alienware. :S But, 330W is a bit over the top. I think 180 should be enough.

Power Supply 101...
First, Watts=VoltsxAmps. If the PS is rated at 200, 300, 500 or even 1000W but has only 19V of "push" it will work 100% fine with any laptop needing 19V. Period. The laptop may only draw say 19Vx10Amps=190Watts from the thing, but thats all its asks for...a higher wattage PS will not "push" more energy into the device than it needs, its the device that places the load on the PS and draws current only for what its rated for. So you could run the G74 with a 100W PS but since it can pull 8 Amps when its working really hard, your PS would have to deliver 19Vx8Amps=~150 Watts, which a 100W could not do without a serious voltage drop, or it might do until something inside it popped! Moral: too much wattage is not a bad thing.
Never plug an adaptor in to your notebook unless it has the same voltage rating that the notebook is rated for. An overvolt will kill your power circuitry in the mainboard. Dead. An undervolt will run your notebook unstably, or not at all (i.e. it may not even turn on).
That Dell 330W doesn't specify the voltage so I would be wary of it.

I have a 180w charging adapter for the G75v and it still seems to get hot. Is that normal?

150 watts for G53JW and much cooler than tiny 90 watt ones used of less powerful notebooks. Because it's really gigatic thus passive cooling seems in action.

All power supplies get warm because the switching mode from AC to DC power is less than 100% efficient. E.g. while your laptop may need 120W from the power supply to play games at full load, etc, what you will be drawing from the wall will be typically 20-30% more (150-170W). This excess power gets turned into heat by the less-than-ideal characteristics of the electronics inside the power supply. So they get warm.

A power supply is most efficient when it is supplying ~50% of its rated max. So, if you want the coolest power supply for your G75, buy a 200W or more adaptor (the G75 will still only draw the 120W it needs, and never 200W!).
