I have a eMachines W5243 sitting around pretty long with a Dead/burnt capacity on motherboard and am going to replace with a LGA 775 motherboard w/Q9550 CPU with 4GB RAM BUT IDK if the 300watts PSU can help it... Ganna add a 240GB HDD with a GT 220... I'll be doing this probably in a month or so since my bro haven't move his stuff in his closet for me to get the motherboard and cpu... Just want to know if the PSU of the eMachines W5243 can handle it, might buy a new one if it can't handle it... I used a Intel's power thing to calculate it and it uses just just under 300 watts or almost 290watts...
