Can you use a power supply with more amps and not fry the unit?

you will need to be allot more specific on what you are trying to do here.
what is the difference in amps.
what is the device
Generally speaking it is good practice to only use the power supply that the device is rated for.
the biggest issue you will have is this
Power = voltage * current (simple version)
if the power supply you had was 12v at 1 amps then you ca supply 12Watts of power
if the power supply you had was 12v at 10 amps then you can supply 120Watts of power
Just because you can supply 10 amps, and all you need is one, means your power supply is bigger than it needs to be. The device will draw what it is intended to draw. Just make sure the voltage matches.

What is a volt-ampere the product of?
A volt - ampere is the unit for the product of voltage and current. This is power. Power = voltage x current. The unit of power is more usually called the watt. Volts x amps = watts.
What is the unit of measure for reactive power?
Volt Amps [volts times amps] is used for reactive and apparent power. Watts (dimensionally the same as volt amps) is used to indicate real power.AnswerReactive power is measured in reactive volt amperes (var).
What is the relationship between voltage power and current?
The unit of power is watts, the unit of current is amps, and the unit of voltage it volts. Power = Voltage X Current Voltage = Power / Current Current = Power / Voltage In electricity, power is symbolized with a P, current with an I, and voltage with a V. The real formula looks like: P = V x I V = P / I I = P / V
Is power factor defined as volt amps divided by apparent power?
No. The volt ampere (V.A) is the unit of measurement of apparent power. Power factor is true power (expressed in watts) divided by apparent power (expressed in volt amperes).
What is the difference between watt and KVA?
VA or volt-amps is also volts times amps, the concept however has been extended to AC power. For DC current:VA = Watts (DC current). In AC if the volts and amps are in phase (for example at a resistive load) then the equation is also:VA=Watts (resistive load)where V is the RMS voltage and A is the RMS amperage.
What size fuse should be used for 2 amp power supply?
If the 2 amps is the output amperage of the power supply, the maximum that should be drawn from the unit is 2 amps. The load amperage that is connected to the power supply should govern the amperage of the fuse used. There is not much range there, the fusing could go from .25 to 2 amps. If the input amperage is 2 amps then the input and output voltage of the power supply should be stated.
Can you use a 9V 850MA power supply on a unit requiring 9V 2100MA?
No. A device that requires 2100 ma or 2.1 amps can not receive enough amperage from a power supply that will only deliver 850 ma or .85 amps.
How much amp for 65w mains charger power supply unit?
To answer this question a voltage is needed. Amps = Watts/Volts.
What is a volt-ampere the product of?
A volt - ampere is the unit for the product of voltage and current. This is power. Power = voltage x current. The unit of power is more usually called the watt. Volts x amps = watts.
Is 8 amps equals 1.5hp?
You can't compare that. Ampere is a unit of electrical current; horse power is a unit of power.
What hardware unit contains the power supply?
The hardware unit that contains the CPU, the RAM, a hard disk, and a power supply is called the "motherboard."
What is the computers power suply called?
it can simply be called a "power supply" or a PSU (power supply unit)
Why does the power supply unit have a fan built?
To keep the power supply cool. If there were no fan the power supply would overheat and fail.
How are amps different from watts and volts?
Amps is an electric current unit and watt is an electric power unit.
What unit of measure is used to measure current?
Ampere is the unit used to measure the current.
What is a measure of the electric power of a appliance?
The watt is the unit of power. For electricity, watts = volts x amps.
How can a power supply be repaired?
A computer's (PC's) power supply is a sealed unit and should be replaced as a whole - It is dangerous to try and repair the inside of that sealed unit (that is why it is sealed).
