Those minimum psu recommendations are for stupid people who buy ultra budget psu that are peak rated
A psu like the Corsair is rated at 430 watts continuously and wont break a sweat running that computer which is never going to draw more than 200 watts total .
Your RAM needs to be 1.5 volt or less according to intel . Cant see the models spec's , but on Newegg you can filter by voltage too .
You wont have an improvement in frame rates by using 8 gig either so if you need to save money then 2 x2 gig is fine
Alright thanks I'll be getting the 8gb g. skill ram and the cosair. Everything checks out alright though? (ram, power, etc) I just want to make sure before I buy and then have to return to newegg because I'm dumb and didn't double check or something. Having both the i3 and the corsair on sale right now is great.
