Does the ECM8000 mic need a mic preamp to work ?

Yes, the preamp supplies the 48 volt phantom voltage required for the electronics in the mic, and also raises the level of the mic signal to a line level required for use with a soundcard.

I have seen that most preamps recommended for use with ECM8000 are mixers. I wish there was a plain simple and cheap one without all the stuff i don't need.

The Behringer XENYX 802 is quite inexpensive and does the job very well. I find it hard to believe they can sell it for this price. The stuff you don't need is just a bonus..

FYI, here is a circuit I used to make a phantom-power supply for testing ECM8000's for a couple of years before I finally bought a 'real' one. If worked okay and it certainly paid for itself.

Audio Technica make a few single pre's which would be good. Or M-Audio have some USB types that would work too. I don't think a DIY pre is a good idea, unless you have means of checking the specs, as calibrating it would be a hassle.
