55W CPU in Laptop with 90W PSU

Have an Acer 9635G, upgraded cpu from an E7350 to T9600 which is rated at 35W, turns out I was sent a E8235 Instead, which is what imacs use, same spec, but 55W, installed in laptop and works fine, should I keep or change? battery seems ok, temps seem ok.

Anyone be carefull if buying cpu's make sure you don't get sent the wrong one

 

55w sounds like alot for a laptop CPU, are you using HWmonitor? If your temps are fine and battery is fine then you shouldn't worry. My E7500 is 65W but then its a desktop replacement notebook with suitable cooling.

 

55W? That could overheat and lead to severe problems, couldn't it? After all, the highest TDP laptop CPU is just 45W. You should send it back and demand a T9600.

 

You probably don't realize it, but it's likely not an error and they sent it to you knowingly. They probably sent you that one because the other one wasn't available or another reason. Most companies have upgrade or substitution policies that people don't bother to read about online, but they're there and they exist. They generally have language stating that they can substitute an item of equal or more value.

If you think it's of lesser value or capability, then the buyer has the right to return it for a full refund. But companies know that few people ever bother to really check the invoices that comes with a purchase. Being a former government QA Manager, I used to buy some pretty expensive hardware for Uncle Sam, and I've seen this tactic used for years by companies looking to make a quick buck. What they do is advertise something cool at a low price, then substitute it at shipping. If the buyer doesn't return or contest it within a certain period, they're stuck with it. When you should be angry is if you got something that you paid money for that is worth a lot less - that is not "Equal or of More Value". But few people bother to check.

You've probably got a better CPU, albeit one that draws more power. It could have the same capability, but might be an older model. Newer components are generally designed to use less and less power, which is good and bad. Good in that it increases battery life. Bad in that it takes less and less to completely screw them up.

A component's given Wattage rating is the component's RATED overall power value. In cases of a component, the watt rating indicates the amount of overall power (Current times Voltage, Current x Voltage x .60 or .70 for computers) that the component is drawing from the system battery or PSU. In terms of the battery or PSU, the wattage rating is the amount of power it can distribute and make available to components. In all cases, you want your power supply/battery to have a wattage rating equal to or (preferably) higher than the total overall wattage of all your components if they were all on. The CPU and GPU are usually the components with the highest wattage ratings.

However, unless it's drawing a LOT more power than it should, it's not an issue.
Bottom line - don't worry about it.

 

DIdn't check the total wattage before replacing it, what is the best device to use?, i.ee in the UK, can you recommend something that I can plug the laptop charger into and then that device in the mains which will tell me the total power, something that will handle up to 600W so I can use to test other devices

 

A Kill-a-Watt will measure power draw.

 

I would have some serious concerns about thermals with that processor. That dissipates what, ~57% more, heat at top load?

 

By law Intel can market a 25 watt processor in a 55watt TDP
They just cant do it the other way around and state a 55watt TDP cpu in a 25 watt TDP

Technically the 55 watt cpu will work fine. Just note the voltage it is running at through CPU-Z and check temperatures at load under CoreTemp, HW Monitor, Everest, etc

What processer do you have? Laptops dont use E model numbers and i have never heard of a e8235?

 

have you checked the battery and temps when gaming? or doing somthing with a high cpu loads?

 

The iMacs (desktop) use special notebook processors with E designation. They are essentially the same as the T series for notebooks but w/ higher TDP.
