The aim of this study is to indentify the relationship between power style, personality dimension and
Leadership style. The sample of this study consists of 300 respondents from six selected company and
were chosen by using simple random sampling. Quantitative method was used in this study and the
data was collected by using questionnaire which consist of the Multifactor Leadership Questionnaire
(MLQx5), Rahim Power Inventory (RLPI) and Big Five Personality Questionnaire (BFPQ). This
questionnaire was used to answer the research questions of leadership style based on leaders’ power
and leaders’ personality among the managers. The reliability of the questionnaire was done by using
Cronbach alpha to find the internal consistency of the questionnaire through pilot study and it shows
that the alpha ranged between 0.71 and 0.874. The result of this study shows that there was a positive
correlation between transformational leadership style and expert and referent powers (r = 0.694 and r =
0.544, respectively), negative correlation between transformational leadership style and legitimate
power, coercive and reward powers (r = -0.428, 0.537, and -0.470 respectively), positive correlation
between transactional leadership style and reward power (r = 0.205). A result also shows that
agreeableness, conscientiousness and openness to experience had a positive correlation with
transformational leadership style (r = 0.268, 0.575 and 0.130, respectively). This study shows that expert
power, conscientiousness and coercive power predicted transformational leadership in the
organization (beta = 0.464, 0.266 and -0.145, respectively). Conversely, reward power predicted to
transactional leadership (beta = 0.205)
