High-flying Burton made the most of their limited chances to see off Paolo di Canio's Swindon Town.
The visitors dominated early on with Alan Connell coming closest to scoring but his glancing header just missed.
A Burton breakaway gave them the lead when Justin Richards ran on to a clearance to cross for Billy Kee, who chested the ball over the line.
Albion doubled their lead when keeper Mattia Lanzano's clearance fell to Jacques Maghoma, who side-footed home.
VIEWS FROM THE DRESSING ROOM
Burton boss Paul Peschisolido told BBC Radio Derby:
"It was good to get two consecutive clean sheets and to win back to back games was also nice. I'm pleased with the performance. It wasn't as fluid as we were against Crewe but it was effective.
"We had players making tackles all over the park. You've got your strikers making tackles, you've got your wide men making tackles in your own box and that's still not stopping us creating chances at the other end and scoring goals."
Swindon Town manager Paolo di Canio told BBC Wiltshire:
"Once again we have possesion of the ball but we cant score a goal. This is my frustration, we don't have a centre forward.
"You have to take your chances. Mattia Lanzarno killed the game.
