Go to SolutionUsing 130W Adapter with Dell Latitude E6430
Hello,
I have a Dell Latitude E6430. Originally, it comes with a 90W adapter, but I’m considering using a Dell 130W adapter instead.
Is it safe to use the 130W adapter with this laptop?
Will it help the CPU to reach higher performance (Turbo Boost), since with a non-original 90W adapter my CPU speed is limited around 2.0 GHz?
I just want to confirm if the official Dell 130W adapter (19.5V, 6.7A) is fully compatible and will not cause any issues for my E6430.
Thank you in advance.
@ejn63 Thank you for your clear explanation. Now I understand that the 130W Dell OEM adapter is safe, but it won’t provide extra performance compared to a 90W OEM adapter. The important point is to use a genuine Dell adapter, not a third-party one. Thanks again for your help.

The system will draw only as much power as it needs, so a 130W Dell OEM adapter will work fine. That said, it will make no performance difference at all, as the system does not need more than a 90W adapter. Being OEM, it will perform better than a third party adapter though - but so would a 90W Dell OEM adapter.
