Ayoze Perez scored his third goal in three games, and at the other end of the spectrum, Fabricio Coloccini scored only his third Premier League goal of his career.
The thing about Newcastle these days is that they have the pace and the endeavour to frighten the life out of opposing defences, and West Brom had no answer for United's strikes on the break.
One moment of magic from ex-Tenerife striker Perez inspired Newcastle to a comfortable win at West Brom, their fifth successive victory in all competitions, but he wouldn't have been in the team if other players were not injured.
OK, it's easy to say Alan Pardew struck lucky with his team selection, but you don't win five games on the bounce due to good fortune or a decent Tarot reading.
This victory was earned, and the team fought to the death to get their rewards.
United's new Spanish striker scored with a back-heeled flick into the far corner past the helpless Ben Foster and it was only what they deserved.
Coloccini's header added the gloss but, make no mistake, United are on the up.
Perez was rewarded with a start while Papiss Cisse, who had been struggling with a knee injury, was on the bench.
With Gabriel Obertan sidelined with a torn thigh muscle and Steven Taylor injured, in came Remy Cabella and Massadio Haidara.
The game initially lacked punch until Sammy Ameobi's curling effort bounced off the top of Foster's crossbar in the 10th minute after Craig Dawson's poor header.
And it took until the 16th minute for the Baggies to conjure their first chance.
A slick move involving Chris Brunt and Anichebe saw the former Everton striker set up Berahino but the striker's shot was pushed over by the stumbling Tim Krul.
There were signs of a blossoming partnership between Berahino and Anichebe and they combined again in the 27th minute to present Anichebe with chance, only for Paul Dummett to thwart him on the edge of the box.
Anichebe was enjoying the physical battle with the Magpies defence but failed to get the better of Coloccini with the game meandering to the break.
But Perez ended the monotony when his wonderful finish fired the visitors ahead just before the break.
Newcastle's quick play caught the Baggies out and, when the excellent Daryl Janmaat crossed low, Perez met it with an expert back-heel to divert the ball into the corner across Foster from 12 yards.
It was a wonderful moment of skill which was so out of keeping with an otherwise scrappy game.
The subdued hosts, with Berahino especially quiet, struggled to respond after the break.
While there was plenty of effort the Baggies lacked quality and Newcastle batted Albion's muted attacks away.
And the Magpies doubled their lead in the 62nd minute when Coloccini crashed in a far-post header after another devastating right-wing cross from Janmaat.
The goal put Newcastle in total control but Andre Wisdom wasted a gift with 11 minutes left when he was left with just Krul to beat after Anichebe pushed the ball into his path.
The on-loan Liverpool defender, though, opted to take a touch before sending a wretched shot wide from just six yards.
With the wasted chance went Albion's final hope, and Foster prevented further misery when he denied Perez a second, superbly tipping over his close-range effort with four minutes left.
