I just recently built my first PC, I usually buy pre-built PCs ( Dell )...but I was told building them yourself was the way to go, so I gave it a shot, and after a bit of frustration I managed to get everything together and working great. Now I know a little more about building PCs, I'm never buying pre-built again. Anyway on to my question....Here's what I have already.
MSI 790FX-GD70 AM3 AMD 790FX ATX AMD Motherboard
AMD Phenom II X4 965 Black Edition Deneb 3.4GHz Socket AM3 140W Quad-Core Processor
MSI R4890 Cyclone OC Radeon HD 4890 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card
Crucial 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600) Dual Channel Kit Desktop Memory...8GB total.
Western Digital Caviar Black WD1001FALS 1TB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive
SAMSUNG DVD Burner Black SATA Model SH-S223L LightScribe Support
COOLER MASTER UCP RS700-AAAAA3 700W ATX12V / EPS12V SLI Certified CrossFire Ready 80 PLUS SILVER Certified Power Supply
What I wanted to know is if my power supply can handle another graphics card and hard drive like the ones I already have ( My tower case also has 2 fans ). It says crossfire ready, but I just want to be sure before I buy them. I know I'm new to this, but it seems like a lot for a 700w power supply, and the graphics card requires no less than 550w PS, so with 2 of them plus another HD I'm not sure. Thanks for your time
