Friends adviced me to buy at least a 600W PSU.

You have a 55 Watt processor and a 75 watt video card. Your whole PC is not using more than 200 watts.

Your system will do fine with good quality 400W PSU. The PSU you currently have is of low quality, hence why it can't handle your components.

Your GPU uses 75W, add the rest of the system at about 150W (usually less) and total would be 225W. 400W PSU is more than enough.
600W range PSU is for high-end system (similar to my Skylake build, full specs in my sig).

Here's PSU Tier list: http://www.tomshardware.co.uk/forum/id-2547993/psu-tier-list.html
Aim for a good quality (Tier two) PSU, preferably great quality (Tier one) PSU if you can afford it.

Here i suggest Seasonic in 400W range.

In the pcpp list you'll find 3 good quality (Tier two) PSUs and 1 great quality (Tier one) PSU.

All my 3 PCs: Skylake, Haswell and AMD are also powered by Seasonic. (Full specs in my sig. Got PRIME series in Skylake, M12II EVO series in Haswell and S12II series in AMD.)
