power supply heat

i have a sager np9262 and a e8600 cpu, one 9800m gtx and one hdd..


my problem is that my psu is really warming and even though that's fine right now, i am going to start upgrading it and i am worried it might fail. i am going to sli it, put a q9650 and two more hdd in it and i am wondering what should i do.


i had a whitebook before almost maxed out but with a t9400. my psu was always cold even at full load. but then i dropped in a qx9300 and then it got so hot. but now it's as hot as my whitebook without the gpu's.

any ideas.

 

Is it too hot to hold? Also, is it making any noises?

 

well i'm using it in a cool room and it hot enough to make me think it's at its limits.

and all it does it whine. start up is the worst. and full loud whins also.

 

later tonight i am going to call sager and see what's up. i don't have the notebook with me so i can't really do much.



i hope they are willing to ship me one overnight with oit the hassle of me sending it to them first. if they do then i'll be a happy customer, i'll repost back what happens.

 

My power supply is really hot and it is also making a "noise".

 

This is a typical case of the piezoelectric effect. All power supplies and motherboards have DC-DC voltage regulators. They consist of resistors, a diode, a current converter, and copper or tungsten coils around magnetic bars, better known as ferrite cores. The ferrite cores wills begin to vibrate and resonate due to magnetic forces and rub against the coils surrounding it at a rapid rate, which causes the sound that you hear. However, this is normal for all electronic devices, though only audible to the human ear in power supplies, motherboards, and very rarely some low voltage CPU's, GPU's, etc. It is primarily dependent on the voltage running through the component as each one has it's own "sweet spot" for resonating.

As long as you put your power supply on a flat surface, it's not going to explode on you. Power supplies are one of the most durable components of a notebook and they are supposed to get hot, even to the touch. A 220W power supply is enough to power a fully loaded D901C so don't worry about it.

 

ok so you think it's just normal then. i'm just worried it's gonna get real hot and fail when i put my other components in there.

 

I have a m570ETU my psu gets really warm and even has a warning "Be careful! May become hot."

 

I'm going to say no, it's not normal, just so you can feel paranoid during the whole process.

 

i know it will get hot. there's no doubt about that. and with my current config now, i not to worried about it. but when i add about 100w more to it what will happen(quad (about 30w more)and sli(about 75w)) do you think my power supply will fail.

 

Lol. i'll wait it out and see what happens then. i'm going to see when the warrenty is up. this way i can get a psu before it ends.

 

Although my NP8662 power supply doesn't get major hot, I still place it on a NEWLink Laptop Cooling Mat during use. You can feel how much heat the mat draws away from the power supply and it appears to keep it cooler.

 

Here's mine. A Li Shin 120W power supply coupled with an APC Notebook SurgeArrest. At home, my power supply sits on an old Logisys hard drive silencer that I pulled from a client's desktop.

 

sager may ship you a new one in advance but you will have to provide a credit card and they will do a hold of funds on it till they get the other one back. if you dont have a credit card they will not do it

 

Mine gets untouchable hot when I plug it into a surge protector with more than one appliance connected to it. When I plug directly into the wall or a surge protector with only my laptop on it, the power supply only gets warm.

 

I am running dual video cards, 3 hard drives and a C2D 8650 (about to be swapped out for a Q9650) with no problems. It gets very hot but has been running fine for well over a year now with no problems. If it is making any noises, they are not heard over the fans of the lappy.

 

ok well i may just get a new one just to be on the safe side. i am relieved that i am not the only one that has this issue and everyone is running fine.


i always have mines into a surge protector. i will try a wall and see what happens.

 

It was never an issue to begin with. You have always been on the safe side this whole time. I doubt that you will ever get to use your second string power supply.

 

Now that is catering to the customer's demands - give 'em what you know they really want!

 

The power supplies do get pretty hot, yes. However there is nothing to worry about. Notebook power supplies are extremely sturdy, and designed to shut themselves down if they get overloaded.

I once overloaded my power supply, and it shut itself down. It wouldn't work for another ten minutes also, in order to cool down properly.

As I said, almost idiot proof design. No need to worry. It won't blow up.
