should i use the psu included in the case?

[TechSwag]

So, im go build myself a gaming pc for a very low budget, i already have all the part, but im a little over budget, which is fine, but i cant go any higher. im using pcpartspicker for a little help, because it is my first build, and im having a little trouble finding a case and psu for under 50. I found a nice, cheap case with a 300 watt psu included. The estimated wattage tool on the site tells
me 249 watts, and someone else told me that the estimated wattage is calculated for best efficiency. im wondering if the psu is gonna be enough, and if it is a reliable psu, thats not gonna ruin my entire build, or make me buy another psu. any suggestions?

What make is the psu?

What parts do you have?

A lot of Mid/High end gpu's for example ask for atleast a 500-550 watt PSU

The Antec Sonata series is the ONLY set of cases that uses half way decent PSUs in them, the Sonata series has Antec Earthwatts PSUs in them. Meanwhile most brand *cough*coolermaster...*cough* are shoving unit thats are too awful to sell on their own so they throw them in cases. 99% of the PSUs that ship with the case are dangerous to use with a midpower gaming PC and will die fantastically with a high power PC.

Which case in particular are you looking at?

If its an Apex case they come with either a unit with an 8A and a 13A rail or a unit with a single 15A rail.... none of these are sufficient for a modern system with any GPU in them since a modern system pulls 80-90% of its power from the 12V rail...
