hi everyone...
this is my first system build.. and im having a problem figuring out what psu i should buy...
and how many watts it should have... could u help a rookie out...

well here are the other parts i got for my homebuild system...(hoping it would be a great gaming pc)

AMD Athlon 64X2 dual core processor 5000+

2048 system memory

500gb hard drive

ECS A780GM-A Motherboard - AMD 780G, Socket AM2+, ATX, Audio, Video, HDMI, PCI Express 2.0, Gigabit LAN, USB 2.0, eSATA, RAID

EVGA GeForce 8800 GTS Video Card - 640MB GDDR3, PCI Express, SLI Ready, (Dual Link) Dual DVI, HDTV, Video Card...

if any of you think that i got incompatible things pls tell....(especially the video card and motherboard...not sure if the video card will fit).. and offcourse dont forget to tell what psu would you recommend for me.. for optimal performance with a good price smwer below $120)

im such a newbie at making systems... thats why i nid your expert help guys.... il be w8n for your replies....

and advanced thank you very much....

A 550 Watt PSU should be fine for that build, although I recommend at least 650 for any new build; it helps upgrade-proof a system.

I have a 450 and stuff runs fine, but I'd get a 650 corsair that is a good unit with room to upgrade, or if you can handle 20 more bucks, the 750, just my 2 cents.

thank you very much... one prblem tho....can u check my mother board and video card and check if they both will fit??

oh yeah... ummm... if the video card memory type is GDDR3.... does it mean you should have a ddr3 memory also... or will my 2048 ddr2 just work fine with my video card...

sori... im really a newbie... but with your help guys... im starting to learn things bit by bit....

long live people who make homebuilt systems...
