Okay, let me first preface by saying: I've read tons of guides (on this site, and elsewhere in internet-land), I've crunched numbers at the various power supply calculators, I've debated til kingdom come already in my own head... But now, I'd like to turn to the community for suggestions.
Here is my current system:
CPU - AMD Phenom II x4 960T "Zosma" (I haven't attempted unlocking the extra cores yet, and haven't overclocked anything either)
Mobo - ASUS M5A97 AM3+ 970 chipset
RAM - 2x4GB G.skill DDR3-1600
Optical - ASUS DVD±RW (SATA)
Sound - on-board, TBD if I'm going to invest in a standalone card
Video -- to be upgraded as soon as my IRS refund gets deposited (hopefully later this week)
PSU -- a Thermaltake non-modular 600W model, also to be upgraded with my IRS refund
Now, I'm all but set on the XFX Double D HD-687A-ZDFC... And I know what technical specs I want in a new PSU: modular, 80+ certified (bronze or higher), multi-GPU capable (has to have at least 4x PCI-e power connectors), and Active PFC. Unless someone can suggest a better sub-$175 card that will fit into my Antec 300 Illusion case, I'm going to buy the above-noted XFX Radeon 6870 card soon with plans to expand to Crossfire in... the future (a month, or three). And yes, I'm open to suggestions.
But I'm really looking for input on picking a power supply. It needs to be powerful enough to run a crossfire setup and leave a little wiggle room to make me comfortable. By my calculations ~750W of 12V power should cover that nicely. I've read certain items that make me want to steer away from a single-rail @ 70amp type of model, and other certain items that make me want to steer away from a multiple-rail type of model which each real and/or virtual rail having ~30amps.
The Raidmax RX-850AE caught my eye as meeting all those technical desires and power needs I believe I will have, but after input overload I'm looking for confirmation or a suggestion of a better route to take.
Thanks in advance, everyone!
