Branded machines such as HP/Dell/E machines/Acer
Etc., are built to a tight specification to do a set
of tasks- attempting to 'improve' then in anyway will almost certainly lead to a loop of expenditure and frustration, of adding components to a basic machine not designed for them.
Indeed some[Dell] are designed with custom parts that can be virtually -unchangeable.[no ports available]

You may be better advised to work out exactly what you want a machine to do - and seek out a selection of components from the likes of click here
or buy a copy of MicroMart[comes out weekly on a Thursday] and start from the bottom up.

click here and see if that model has more than one PSU Listed for it and you will get a part number and a price from HP,

Just looked at the specs sheet for your pc and it looks like a pretty standard ATX desktop. I suspect as long as it uses standard connectors you could put a more powerful ATX psu in there without problem. The psu itelf won't add to the heat in the case, it's own cooling fan simply exhausts from the back of the case. If you're worried about cooling, when choosing a graphics card it would be best to go for a dual slot model which actively pushes the hot air out of the case rather than blowing it around inside.

thank you, i just wanted to have a more powerful graphics card at the end of the day cause the one inside is 256 and uses onboard memory to bump upto 1.2 gb
