Steven Fox, of Hendersonville, Tenn., the 2012 U.S. Amateur champion and Chris Williams, of Moscow, Idaho, No. 1 in the World Amateur Golf Ranking (WAGR), both shot 2-under 69 for the USA. Justin Thomas, of Goshen, Ky., posted a non-counting 1-under 70.
"It has been since 2004 that the trophy has found its way to the USA and it is great to have it coming back to our shores," said USA captain Jim Vernon,a past president of the USGA. "They are three guys who bonded well and played golf as a team."
The previous low total for 54 holes was 407 by the USA in Puerto Rico in the 2004 WATC, which was also played at 54 holes because of weather.
"It's fun to win as an individual," said Williams, a University of Washington senior who won the 2012 Western Amateur. "But to win as a team is awesome and it doesn't get any better than doing it as representative of the USA."
Despite a strong challenge from Mexico, which finished second at 19-under 409, led by Sebastian Vazquez's individual low total of 15-under 199, the USA led from the start to the finish, setting records along the way.
The Mexican team, playing in its 26th WATC, won its first medal.
"We had good expectations this week but this is a dream come true," said Mexican captain Jorge Coughlan. "I played in this a long time ago ) and being captain is very satisfying. This is Sebastian's last amateur tournament and there is no better way to go out than winning the World Amateur. He is going to be a heck of a professional."
The Americans, in winning their 24th medal in the 28 Eisenhower Trophy competitions, broke team marks for lowest 18-, 36- and 54-hole scores.
Four strokes behind Mexico at 15-under-par 413 as three-way bronze medalists are: defending champion France, Germany and the Republic of Korea.
Canada and Norway tied for sixth at 417, with England in eighth at 418, and Japan, Venezuela and Spain tied for ninth at 419.
Australia again improved in round three, moving from overnight 22nd to a share of 15th, all three of the Australian team of Cameron Smith, Daniel Nisbet and Matt Stieger recording final rounds of 68.
Smith finished as the leading Australian in the individual standings when tied for 13th.
New Zealand finished 24th with Vaughn McCall their leading performer when he also finished 13th.
The World Amateur Team Championship is a biennial international amateur competition, begun in 1958. It is conducted by the International Golf Federation (IGF), which comprises national governing bodies of golf in 126 countries and international professional tours. The competition, which is being held for the 28th time, is rotated among three geographic zones: Asia-Pacific, Americas and Europe-Africa.
This year's event is hosted by the Turkish Golf Federation. The teams play for the Eisenhower Trophy. The IGF is the international federation for golf for the International Olympic Committee and will conduct the Olympic golf competition in Rio de Janeiro in 2016.
In each round, the total of the two lowest scores from each team constitutes the team score for the round. The 54-hole total is the team's score for the championship.
Turkey, the host team, finished tied for 36th.
The winning team takes custody of the Eisenhower Trophy for two years and each team member receives a gold medal. The second-place team members receive silver medals and the third-place teams receive bronze medals.
