Ok so you have a SATA hard drive (seagate aswell good make).

So you need to select SATA 1 HDD.

now I get 446W, that sound about right?

Ye sounds about right i would get about a 550 watt power supply. And make sure it is a reputable brand like enermax, seasonic, corsair, antec, thermaltake and hiper.

This one is nice btw HIPER HPU-4K580-MS 580W Power Supply - Retail at Newegg.com and has modular cabling which means you only plug in the power supply cables you need increasing airflow and tidiness!

ok then cool, thanks for your help hommie

marked as answered. Hope you have fun with your new gpu!

Hey I just did something. I decided to open up the PC and looked at the Power Supply. It is a "Delta Electronics INC." Model "DPS-400LB" and on OutPut it says 364.7W MAX. Is that a problem? Do I defenitly need a new Power Supply? If so do I need 1 that is specifically for Sony or do they have the same connectios? Also I was looking at some Power Supply prices and they go all over the place. There are the 580W for like $40 and there are the 580W for like $100. What are the things I should be looking at, if I do need a new Power Supply? Thanks
