Invoke an exe from PowerShell and get feedback on success or failure

.\YOUREXE.exe
if($LASTEXITCODE -eq 0)
{
    Write-Host "The last PS command executed successfully"
} 
else 
{
    Write-Host "The last PS command failed"
}

Have you tried using the $LASTEXITCODE variable? It will contain the exit code of the last .exe that was invoked.
