Where can I buy a 100W or more Magsafe?
I got 1 SSD in my primary Hard Drive spot and 1 HDD in my optical bay and when my mac Use a lot of GPU and CPU, the 85W MagSafe cannot support it and turn Off..
So does anyone know where can i buy a Mag safe with more then 85W, or how can I modified mine ?
i have not heard of this before, i suspect you might have some other type of problem.
The 85W adapter provides 4.6amp as i remember @ 85W. which should be plenty for what you are describing.....
I would remove your 2nd hard drive and run a stress test on your mac ( a program designed to push it to the max for an extended period of time..... you should have something built into OSX to do this..... or just render something.....o
Then if no problems, put your 2nd hard drive back in, and do it again. If your 2nd hard drive caddy or power connector however it is hooked up may be to blame, which is a wild guess on my part...... It may also just be getting quite hot with the 2nd drive installed, if too hot the computer will turn it's self off. (your question didn't say if it powered shutdown or just off....... like turning off a light in a room).
Someone else might be able to provide more information as i have not had to deal with this exact issue before.
You can build a DC inverter..... i have one...... i can power car lights or something as small as router with it. However it is quite large since it was built before i was born and designed to power multiple things at once with various options for how much power it produces...so handled without care it would easily blow something up........... so making something to do what your asking would be a fairly large device and quite an undertaking since the power adapter for your mac does more then just produce the power needed for the computer. ( some kind of homemade thing or modification of your current power supply may blow up your computer).
I have a similar problem
I have a 2.5 i7 with a internal 7200 rpm drive and when I'm using the !$%@ ut of it my battery stops charging my fan run at max speed and stat shows all the cores at 70%
so i did some searching and found this firmware update
its not compatible with my mac but I think it works with yours
hope it helps
and if you find a 100w magsafe adaptor let me know I want one too
