Accuracy in power adapter to harddrive 0.05A difference

I opened an external harddrive.

The drive inside had

5VDC - 0.7A

12VDC - 0.5A

The drive I want to replace it with has:

5VDC - 0.60A

12VDC - 0.45A

Can I replace the drive without any problem or will it break down due to the extra Amp pushed into it?

Answer this question I have this problem too

Is this a good question?

@junounchanged you are fine with that drive. The difference that small in amperage is negligible.

Hi, To add to OT03's answer, as long as the voltage is the same the device will only draw the current that it needs. The only way to get more current to flow is to increase the voltage supply. (Ohm's Law)
