i like the aspire 500watt ones.

 

[TRDCorolla1]

None of those links work...

 

[kevin o.]

sorry

sorry i couldn't get them to work, so i just listed the parts.

 

[Dishdog]

does your MOBO support DDR2?

 

[kevin o.]

i'm not sure

this will probably sound stupid, but i'm not totally sure what a DDR2 is. In the product description is says: DDR Standard: DDR 400 (PC 3200).
I'm sorry i don't understand everything quite yet. I'm fairly new at computer building. I'll give you a link to the site the MoBo is on.

[Dishdog]

it doesn't support DDR2. the highest RAM it can takes is DDR 400 (PC3200)

 

[kevin o.]

sorry again

is that a bad thing? And do you know if all my parts are compatable? Oh and one more thing do i need a sound card right away, or can that wait?

 

[Kuberr]

That can wait. But yeah, you shouldnt try sticking DDR2 RAM in a DDR motherboard.
