Guys....

For those using M17XR(x) and M18R1/2 and planned to upgrade GPU (single GPU), here's what I've tested today on the power consumption.

Mine is M18XR1 CPU I7-2670QM (45W TDP) with upgraded GPU (From GTX560M (75W TDP) to GTX780M (100W TDP)). Everything else are factory standard except for an additional of SSD.

Here are what I observed:

a. Fully Charged Battery
1. During idle, Power Consumption is ranging around 35W
2. (Only) the CPU Stress test gain the wattage to around 81
3. (Only) the GPU Stress test gain the wattage to around 137W
4. Stress test the CPU + GPU + FPU + System memory = around 178W Spike at 183W)

b. While Charging
1. During idle, Power Consumption was ranging around 110W
2. (Only) the CPU Stress test gain the wattage to 156W
3. (Only) the GPU Stress test gain the wattage to around 211W
4. Stress test the CPU + GPU + FPU + System memory = around 257W (Spike at 261W)

I am using this wattage meter :



The software : AIDA64 - System Stability Test

My conclusion :
1. When battery full (No charging) with a single GPU (100W TDP GPU), I do not see any problem to use the 240W Power Adaptor.
2. When battery is charging, the 240W adapter should be ok for gaming. Sincerely, I haven't found any game that stress out CPU together with GPU to the max. But if there is one, than you might facing throttling issue or some other problem.
3. If you are using CPU which have higher TDP (than mine) and planned for GTX980M (122W TDP) upgrade, you should consider using 330W adapter.
4. The wattage gain as per TDP specs is real. I mean, if your GPU TDP is 100W, when you stress it to the max, it will give you near exact figure.

Hope this could help someone that still wondering whether should or shouldn't he upgrade the power adapter when upgrade GPU or CPU.

Adios...

What..? Seriously the new 17" comes with 180w adapter? Wowww...i couldn't say more. Maybe the new machine using less power a.k.a energy saver. They need to test the wattage just to find it out. But maybe it just enough juice to power up all the components. Like i said, i doubt that you wanna play a game which stress all out the CPU and GPU until mouse movement and typing also lagging....

Intel 4th/5th Gen = 47W TDP
GTX980M = 122W
Full blast on both required 169W. Not including mainboard, screen power consumption...blablabla...& if battery is charging too?
