Well I dont have a budget for the power supply but as i noticed on the HP site, you can insert GeForce GT 310 which needs a MINIMUM of 300W power xD, so if i dont change the power supply it wont run at all? because i dont want to go through going getting a new power supply ..
Well if you don't have the money for a new PSU the next best thing would be to get a less powerful card that doesn't require as much power.The best card you can get with that PSU is probably the 6670/5670.
What reosultion is your monitor and what games do you play? I can give you some figures on what type of performance you'll expect with that card.
Yes it does consume less power than your 300 watt but the things with PC vendors like HP is that the PSU's they supply with their PC's aren't that great(bottom of the barrel sort of speak).They may advertise 300 watts but in truth they probably don't even provide over 200watts.
what i meant before is that i dont have limits on the money .. but its just that i need a good power supply and also if i change the power supply myself it would void the warranty from HP as I understand, they have to change the parts on their own inorder to not void it.. xD
what good powersupplies do you recommend?
Your mobo will support any type of PSU as long as it has a 24 pin conntector which all PSU's do.
But what is a cause for concern is the fact that it's a mini-tower case which would restrict the size of the PSU you can fit.I reccomend you measure your current PSU(Height&Length).After you do that measure how much space you have in total for a new PSU.
