Is it OK if a newly purchased electrolytic capacitor is supplying higher capacitance?
Power supply electrolytic capacitors often have a tolerance of +/-20% or even -20/+50% (I've seen -20/+80%). Usually a larger capacitance does no harm (as you might guess from the way the tolerances are specified). 

Your capacitor measures +25% (assuming the meter is measuring it accurately), which may or may not be within tolerance, but normally a larger capacitance does no harm, within reason. A much smaller capacitance than nominal would be a much larger cause for concern.
