Hello. Here are the three websites that I find very useful.
http://scholar.google.co.in/ While this site is not restricted to psychology specifically, it has a wide research database. I have been relying on this website for many years and I always get something useful.
http://www.scirp.org/journal/psych/ This website publishes open access journals. I have come by this website recently. It is especially useful when there is a dearth of access to psychology journals.
https://www.psychologytoday.com/ It is a very interesting collection of articles, easy to read and covering a variety of topics.
