The midfielder, who has represented France at under-21 level, completed the move on Tuesday - and Glenn Roeder says he is delighted to have secured his services.
Middlesbrough and another French Premiership side were amongst those looking to sign him, but Glenn says: "He had a day with us last week and he really caught our imagination.
"I first saw him a couple of years ago, and although I wasn't going to watch him, he always caught the eye.
"He is 6'1", has made 120 or so starts for PSG, and has played in the Champions' League and the UEFA Cup."
Explaining why he feels PSG are allowing a player with such obvious talent to go, he says: "The coach Fernandez has a very big squad there, having brought his own players in since he took over, and he probably views it that a lot of players are from previous managers.
"It is quite common in football for a new manager to make changes, and, when you look at it, several players have left PSG such as Laurent Robert last year, Okocha to Bolton this year, Aliou Cisse - who is no relation to Edouard - to Birmingham, and so on."
Glenn has stated in the past that he is not just looking for players with talent, but players who can flourish in the cut and thrust of the Premiership - and he feels France is a good market to go for.
"When you look at it, Arsenal and Liverpool with their French managers have brought in a lot of players from the French league.
"And we have Sebastien Schemmel, who had an excellent season last year, Fredi Kanoute has been terrific, and Laurent Courtois had his moments earlier last season as well."
As well as being impressed with Edouard's physical capabilities, Glenn says he is capable of performing different roles for the club.
"Edouard is a versatile player who can play in the central areas of midfield, and also tucked in from wide positions as well."
The player himself knows he faces stiff competition for a midfield spot - but is not looking to make up the numbers, as Glenn explains: "He comes from a big squad at PSG and he knows the situation - but he is here to play first team football.
"If he really impresses we will give him a permanent deal, and a fee has already been agreed if it comes to that.
"This is the way Fredi came to the club, and we are hoping Edouard will be just as successful.
"We have some excellent midfield players - Joe Cole, Trevor Sinclair, Michael Carrick, Steve Lomas, Don Hutchison, Richard Garcia pushing on and improving, and John Moncur not giving up without a fight in his last season.
"But hopefully Edouard can bring more competition because I want to create a situation where players know they have to perform.
"Last season we were so short that players knew they would play whatever happened, but we were fortunate because they were so motivated and up for it - and that really showed in the last six or seven games when we didn't drop off after reaching 40 points, as so many teams did.
"I wouldn't sign a player that just wants to sit on the bench and, even in the case of Raimond Van der Gouw, although he is an understudy, he still wants to play."
