Your competitive HS will be taken into consideration but the reality is that 6 of the 9 UC campuses have average UC GPA’s above a 4.0. Your SAT score is far better than your ACT score, so hopefully you submitted your SAT score. You seem to be very capable student, but unless you have some other extenuating circumstances which impacted your grades, most of the UC’s will be tough admits since they tend to be very GPA focused.
Although your personal insight essays and EC’s will all contribute to your chances, your GPA will tough to overcome.
2018 UC capped weighted GPA averages:

UCR: 63.3%
UCM: 88.7%
High Match: Santa Cruz
Low Reach/Reach: Irvine, Santa Barbara and San Diego
High Reach: UCLA
For Cal Poly SLO, Psychology is a competitive major and again your GPA is well below the averages for the College of Liberal Studies which was a 4.04 last year. SLO will be a Reach school.
The rest of the CSU’s admit by Eligibility index and major, so your EI calculates out to 4246.
SDSU: Match/High Match since Psychology is one of the most popular majors
Cal poly Pomona: Match/Target
Other than SFSU, I see no other safety school. I would add San Jose State and Cal State Long Beach for more Target/Match schools along with UC Riverside which has a very good Psychology program.
Best of luck.
