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 .

For two of those 4890's, you would need a minimum of an 850 or 900 watt power supply and my choice would be the 1000 watt for two cards like those:

Well, It's a good thing I checked here before ordering , I guess I'll just hold off then and get some use from the PS I just bought, and maybe upgrade in a couple of years...Thanks for your help

I am happy you did also, because running two cards like that with a 700 watt power supply could cause you to burn up good computer components (like PSU, memory, motherboard, video card) from a lack of power. That is one powerful video card and while the 700 will run one of them, you would need at least an 850 for two of them.

One last question, do you think that I have enough power for just the extra Hard drive?

My System


Sure. Hard drives mostly draw power from the +5V rail, and the +12V rail is what we're concerned about. They draw some from the +12V but no more than a couple watts each.
