While my PSU is not "SLI or Crossfire Certified", I think it MIGHT Be able to do Crossfire. I want to run 2x HIS IceQ Radeon HD 4670's in Crossfire. As you may know, these cards are about $79, compared to the HD 4850, which is about $200 [and in benchmarking, the two 4670's outperform one HD 4850]. These cards also do not require PCI-e power connectors, indicating they are low on the power supply requirements. Here is my system build:
Processor: Wolfdale E8400 [Not OC'd, don't intend to]
RAM: G-Skill 4GB PC2-6400 DDR2 SDRAM
HDD's: 640GB [7200.11 RPM, in mail] 250 GB [5400.11 RPM I think]
OS: Windows Vista Home Premium 64-bit OEM [in mail]
Graphics card: HIS HD Radeon 4670
Power Supply: Rosewill 550W [Here: http://www.newegg.com/Product/Produc...2E16817182017]
Could probably just upgrade my power supply anyways [afterwards?]. But, then, that'd end up being more expensive than the 4850, but, then again, when I replaced the two Crossfiring cards in the end, I'd have to deal with the Crossfire issue then, so...
Here's the PSU I'm thinking of [I like LED lights, lol]:
Still, will my current Rosewill support two Crossfire'd 4670's without exploding, dying, blowing up, getting eaten by zombies, raped by Renee Zellweger, etc.
