Third man admits robbery at bank.
Robert Court, 23, made a short appearance at Mold Crown Court and pleaded guilty to the robbery, which took place in May.
He was remanded in custody pending sentence along with two other who have previously pleaded guilty.
The gang got away with pounds 13,000 and 200 euros.
Judge Rhys Rowlands was told that Court, from the Solihull area, had also pleaded guilty to a separate robbery of cash in transit in Stoke Crown Court and was awaiting sentence for that as well.
He was remanded in custody to be sentenced in January.
Micquel Daviel France and Mark Ricardo Lawlor, pleaded guilty to the Machynlleth robbery in September.
Prosecuting barrister John Wyn Williams described it as a pre-planned, sophisticated and professional robbery involving money in transit to a bank.
CCTV showed a G4S van pulling up outside the bank and the guard walking in.
Lawlor was seen running in seconds later, where he pushed him to the floor and snatched the cash box. France, also masked, blocked the door.
They fled into the waiting car where it was alleged that Court was the getaway driver.
