I'm working on building my first computer system. It's been a blast and I've learned so much. To get down to it I'm stuck when it comes to the PSU. I've been researching for over three days now and I'm beginning to understand but I would appreciate any assistance. The system I am building is this:
Motherboard: ASUS M4N75TD chipset: Nforce 750a SLI
CPU: AMD Phenom II x4 965 Black Edition
GPU: x2 Geforce GTX 260 216 processor
Ram x2 2GB 240pin ddr3 sticks
HDD: standard 3.5in 7200Rpms
From an older system a dvd/cd rw drive.
x2 120mm case fans and the stock cpu fan
OS: Windows 7 Home
I nearly have the computer completed I just need to determine what kind of power supply is needed and the wattage. I already know it needs to be SLI compatible but thats about it. I've used tools online to help determine what PSU i need but they are all drastically different.
eXtreme Power Supply Calculator Lite v2.5 rates 536W with a 15 percent capacitor aging
Newegg says 796W
Journy says 575W
vbutils says 609W
MSI Recommends 800W
Asus recommended 900W
Corsier Recommended 950W
So yeah... I'm unsure. Either a flat out answer or a point in the right direction for learning would be great. I understand about 12v 5v and 3v rails but not enough. I've been at this for 3 days and would just like some help.
