W760CUH i7 throttling?

I've recently cancelled a Dell Studio 1557 because of the throttling problem those laptops are experiencing. Now I've found another laptop that meets all my requirements, the XXODD XNi760cuh (rebranded Clevo W760CUH).
I was quitte happy until I noticed that it came with a 90w AC adapter (like the Dell).

Specs of the Clevo are:
Core i7-820QM
4GB of DDR3 1333MHz
500GB 7200RPM harddisk
15,6" 1600x900 LED screen
Ati HD4570 with 512MB of GDDR2

Now my question is: will the CPU throttle when I stress it (and the graphic card at the same time)?
I've already called the XXODD tech support and they assured me it shouldn't happen, but I'm a little suspicous because of the whole Dell thing.

All opinions are greatly appreciated

Thanks in advance,

No it shouldn't happen, I was told not on AC or battery, however performance drops heavily when running battery, however this is to be expected of any system.

The only ones I know of throttling were the Dell XPS (CPU), alienware (CPU and GPU)

Asus only on battery.

 

The fact is that the pwr adapter is substandard for the total system components. Particularly if the adapter is also charging the battery at the time that you are stressing the system. In the case of idont's sys.. a 120 watt pwr. adapter should be fine. Asus 73g for example has a 150 watt pwr adapter that matches their 720qm cpu and ATI 5780 GPU just fine. THe 5780 dras an estimated 25 watts while the 280/285 draw about 75 watts - go figure. Sagers's 860 & 870 LT's only have a meager 120 watt PWR adapter and they need at least a 160 to 180 watt unit depending on the CPU used and the load placed on them. Finally, I would like to point out that the specs. of CPU TDP (as well as GPU's to an extent) are misleading as it is the - luck of the draw- as some will throttle down at lower temps, just as some can be over clocked much higher than normal. One can go through the various threads here and view the results of similar config's but with differencing results.

 

And that is why I have started this thread. I too have my doubts the adapter will provide enough power, as the notebook comes with a 90 watt one. Any more opinions about this?

Also thank you too for your input, fluffyuk.

 

I've found a graph that may support the fact that a 90w adapter is enough:

The tested laptop (I7-820QM, GT240M, 4GB DDR3, 16") hits a peak of just 74W under full load. When all four cores are manually throttled to 1,2GHz, the laptop consumes 52W at full load.

Again, all comments are greatly appreciated

 

The thing to remember here is that TDP is _not_ power draw, and, moreover, is a rating of the heat produced when the component is operating at maximum capacity, which should almost never happen in any conventional situation. Additionally, a PSU can usually provide more than it's rated wattage (usually up to about 50% more), albeit usually not for an extended period of time. I don't think any current W860CU or W870CU owners have noticed any throttling with their 120 watt power adaptors unless they were overclocking.

If the OP is really worried, and if the problem is actually one of power supply (it isn't always, take a look at the M15x throttling thread for a situation where throttling was not caused by the power supply, but by a deliberately implemented Dell BIOS), I've heard that all Clevos use the DC input socket, and thus he could probably buy a W860CU power adaptor and use that, if needed.
