The company, which trades as Dixons, Currys, PC World, returned an operating profit of £2.5 million compared to £1.4 million the previous year.
DSG Ireland said sales in newer technology such as MP3 players, iPods and digital cameras, along with flat panel TVs, refrigeration products and washing machines were strong.
The company - which already has 17 outlets in Ireland - said it intends to open four new stores this year, creating 125 new jobs and bring its workforce to 600.
DSG Ireland opened a PC World store at Airside retail and business park, North Dublin, on June 16th.
Another PC World store is scheduled to open at Carrickmines in the south of Dublin in late August.
The UK’s parent company Dixons Group today posted full-year profits in line with market expectations.
It announced £30 million pounds of cost cuts as it grapples with a challenging trading environment.
And with non-UK operations accounting for an ever-increasing proportion of sales and profits, the group will change its name to DSG International in a move it said would reflect its international reach.
The company said pretax profit fell 8 percent to £336.8 million, just pipping analysts' mean forecast of £336 million.
