Alienware M17x R1 PSU Fuse Issue

Hi,

I have recently upgraded my M17x to a QX9300 processor, which I overclock happily to 2.93GHz using throttlestop. However after a period of time whilst gaming I find that the fuse blows on the PSU.

The standard fuse rating is 5A and I guess that now that I am overclocking and also using several usb devices that I am drawing too much power.

My question is whether it would be safe for me to change the fuse for a higher rated one and carry on as usual or should I be investigated something else wrt to how much power I am drawing from the PSU itself.

Any ideas? Has anyone met this before from the M17x R1?

Thanks for any help.

 

Fuse are rated to fail before irreversible damage is done to the equipment/device they are protecting. Personally, i sugest you to stick with the original one or else next time can be the psu to fail.

 

Yeah, that's my worry and what I think might happen. If this is the case would it help to remove some of the devices being powered by the laptop whilst over clocking and gaming? Or do you think this would be immaterial relative to the drain on the psu caused by the by the graphics and cpu?

 

How much higher is the TDP of that cpu vs the old one?

 

Spec max TDP for the current QX9300 is 45W
Spec max TDP for the old T9800 I had was 35W.

Not sure if this matters but the only two times the PSU either shut down or blew its fuse is when I played Starcraft 2 on max settings...this always seems to be a good test of stability no matter what I change in the laptop.

I am not sure what my PSU is rated for but I have quite an early model and I have found mention of an older PSU which only drives up to 11A
Current M17x's are shipped with a PSU rated 240w 19.5V 12.3A, model J211H I think.

 

I replaced my T9600 with a QX9300 that I bought from starmicro a few months ago and I have not had any problems with it. I overclocked mine using the bios, ever since it was installed I have been running at 2.8 with no issues and no difference in temperatures.
Maybe you should use bios to overclock and not throttle stop. To overclock in bios just increase your multiplier.

 

Hrm. Maybe I'll downclock it from where I have been overclocking it so far and see if this stops the PSU turning off.

OOI, what is your PSU rated for? Is it 240w 19.5V 12.3A (or this older one with 11A on it that I seem to have found being mentioned on the internet in a few places...I have yet to be able to check mine at home)

Update: mine is a 240w 19.5V 12.3A after all so this doesn't seem to be the issue. Could it just be on its way out I wonder

 

I have the same PSU as you do the 19.5V 12.3A, It could be the clock settings, I have heard and dont know if there is any truth to it, but.... I have heard that with the qx9300 multiplier set to give you 3GHz its stable all day long, and I havent had any problems with it set for me to have 2.8GHz, but in between and odd frequencies begin to generate excessive power pulls and heat... I dont think there is any truth to it and I havent really played with it all that much, But I would suggest either going higher or lower on your settings to find a stable setting
