Connacht ran in four tries at the Sportsground, as they cruised past Southern Kings 32-10 to collect their first Pro 14 win under new coach Kieran Keane.
Tom Farrell, Eoghan Masterson, Ultan Dillane and Darragh Leader all went over for the hosts, who ran in three tries before the break, by which time they led 24-5.
Centre Berton Klaasen crossed for the Kings in between tries from Farrell and Masterson. And, after Connacht's Finlay Bealham had been sin-binned, Leader's 69th-minute try secured the bonus point.
Another home player, John Muldoon, also saw yellow with Kings' replacement prop Luvuyo Pupuma claiming the final five points of the evening.
Connacht had to soak up some early Kings pressure, including a strong run from centre Luzuko Vulindlu, before a Jarrad Butler steal on the ground launched the home side forward.
The westerners' first attacking platform saw them penalised for obstruction at a maul, but with Kings winger Sibusiso Sithole sin-binned in the 11th minute for lifting Jack Carty above the horizontal and dropping him, Keane's charges soon took advantage.
Connacht mauled their way into try-scoring range and, after Leader was denied in the right corner, Farrell was fed in midfield before stepping inside an attempted tackle to score under the posts.
Carty converted and then turned a scrum penalty into three points, with Dillane, Matt Healy and returning full-back Tiernan O'Halloran popping up regularly in attack.
However, there was nothing O'Halloran could do when Klaasen finished off a well-worked try in the left corner, following good work from Masixole Banda, and half-backs Kurt Coleman and Godlen Masimla.
Connacht responded quickly from the restart, Farrell getting past two defenders with flanker Masterson eventually crashing over to the left of the posts.
The province's third seven-pointer followed right on half-time, when lock Dillane drove in under the posts to widen the margin to 19 points.
Connacht's scrum remained on top, earning a 47th minute penalty which Carty capitalised on.
The hosts should have made more of a jinking break from scrum-half Marmion, but the Kings held out and Bealham's no-arms tackle on Banda left Connacht a man down once again.
A gilt-edged opportunity was missed when Pupuma marginally lost control of the ball as he lunged for the try-line.
The bonus try arrived after replacement Steve Crosbie's scooped pass led to winger Leader stretching over in the right corner for number four.
The Kings kept their heads up and their persistence was rewarded. Facing 14 men, after Muldoon was called for a shoulder charge on his opposite number Andisa Nstila, the tourists set up Pupuma for a short rumble to the line, three minutes from time.
