750 watts is enough, but it depends on the amperage on the +12V rail.

I might be concerned.
Every quality modern 750w psu will have at least 4 6 pin connectors.
Since you do not, you may have a poor quality psu that can not deliver adequate power.

Look at the data plate and see if it tells you how many amps can be delivered @+12v.
It should be something like 62A.

If you have anything close, then using molex to 6 pin adapters will work.

But from my reading, this looks like a cheap psu that should be replaced.

it cost 50 euro
so it really cheap
but when it deliverd more dan 12v then can my psu handle it?
