Yes, you are totally fine. Power Supply Calculator says it uses average of 270 watts.

Its irrelevant if a cheap psu has a low 12v rail. It can still fail no matter the watts.
Risk your £200 board and chip at your peril. Check the ampage and make.

It is all on a sticker on the psu. Look, I am going to spell it out for you kids, its come up all day long.
You need to be putting something like THIS;

In your shop bought pc's before you stuff graphics cards in them, or it will

12 Volt rail output 34 amps. Cost £35.
The psu in a shop bought pc costs about £8 cos there is no power and no protection. When it dies it can destroy your machine. st gen i5 not a new unit, is it? Already tired. Replace or wait for the bang.
