Riot Games announced on 19 December 2019 that Hong Kong organisation Talon Esports would be one of ten teams participating in the newly created Pacific Championship Series.

[1][2][3] Talon Esports' first player was announced on 1 January, with top laner Su "Hanabi" Chia-hsiang joining from Flash Wolves.

This forced Talon Esports to play in the semifinal match in the losers' bracket for another chance at qualifying for the finals, which they did after narrowly defeating ahq once again.

[11][12] Mid laner Park "Tank" Dan-won was brought in as a substitute for the summer split, but was later promoted to the starting position after the departure of Candy on 9 July 2020.

PSG Talon managed to defeat Machi Esports in a close semifinals rematch, qualifying the team for the summer finals and the 2020 World Championship.

[15] During the 2020 Worlds Group Draw Show, it was revealed that River and Tank would be unable to attend the play-in stage due to delayed visas, and that Hsiao "Kongyue" Jen-tso and Chen "Uniboy" Chang-chu would be loaned from ahq eSports Club to replace them.

[16] The organisation confirmed this in an official announcement the next day, and further stated that Unified would also be unable to participate in the first half of the play-in stage for the same reason.

[18] PSG Talon later topped their group after winning a tiebreaker match against the Unicorns of Love, qualifying the team for the tournament's main event.

Beyond Gaming's owner, Xue "Dinter" Hong-wei, personally reached out to PSG Talon prior to the announcement and offered to loan out his team's bot laner, Chiu "Doggo" Tzu-chuan, for the duration of the tournament.

[26] Repeating their successes in the spring split, PSG Talon placed first in the summer regular season, finishing undefeated, and swept J Team in the second round of the winners' bracket.

[27] After sweeping J Team once again, PSG Talon qualified for the 2021 World Championship and their fourth consecutive PCS finals, where they defeated Beyond Gaming after another close series.

After sweeping newcomers Deep Cross Gaming, PSG Talon advanced to the winners' bracket semifinals, where they lost to CTBC Flying Oyster, which consisted of several ex-Machi and ex-J Team players.

[36] PSG Talon managed to defeat J Team after a close series in the losers' bracket semifinals and advanced to their fifth consecutive PCS finals.

[36] Avoiding the mistakes of their last series against CTBC Flying Oyster, PSG Talon narrowly won the last game to claim their fourth PCS title and qualify for the 2022 Mid-Season Invitational (MSI 2022).

PSG Talon had a strong start to the spring split, and the team's performance improved even further after they signed Yu "Junjia" Chun-chia, a former jungler of the LPL's Edward Gaming.

After narrowly defeating Impunity Esports and CTBC Flying Oyster in the winners' bracket second round and semifinals, respectively, PSG Talon advanced to their sixth PCS finals.

PSG Talon swept Frank Esports to claim their fifth PCS title, as well as a spot in the play-in stage of the 2023 Mid-Season Invitational (MSI 2023).
