As explained in the answer by DhruvJoshi, the collation is forced on both the sides.

To work around this problem, you could create a function (that performs the collation) which takes the 'string to be collated' as argument and returns collated string.

You could then call the function on one side of the check condition.

The function may look something like this:

create function dbo.convert_ascii(@input nvarchar(500))
returns varchar(500)
as
begin
declare @collatedstring varchar(500)
set @collatedstring = CAST(@input AS varchar(100)) 
COLLATE SQL_Latin1_General_CP1253_CI_AI
return collatedstring 
end

And you could invoke it this way:

if 'ÄÊÍABCDE' = dbo.convert_ascii('ÄÊÍABCDE')
print 'same' 
else 
print 'not same'

This should work.
