Scenario:
Just picked up PNY's new 9800GT 512MB "Energy Efficient Edition" GPU (http://www3.pny.com/9800-GT-512MB-PCIe-P2814C331.aspx) today for $84.99 after rebate at Fry's, and I'm trying to decide whether to keep it.
My system is an OEM HP Pavilion Elite m9252p (http://h10025.www1.hp.com/ewfrf/wc/...78&lc=en&dlc=en&cc=us&product=3688705&lang=en) that came with a custom Asus-built 8500GT. All in all, a relative power house with the potential to be a decent gaming rig except that HP skimped on the PSU (http://itwinkle.stores.yahoo.net/hp35posu51.html). I'm not too keen on shelling out another $50+ or so for a new PSU at the moment.
Nvidia seems to have come out with a new lower-energy-consumption version of the venerable 9800GT. The specs are slightly gimped, though probably unnoticeable in practice, compared to the conventional version, and it promises up to 30% less energy use and does not require a supplementary PCI-E power connector.
So far I've come across PNY's version and BFG's (http://www.bfgtech.com/bfgr98512gtge.aspx). Examination of the system requirements for each reveals that the PNY demands "[a] minimum 400W or greater system power supply (with a minimum 12V current rating of 26A)," while the BFG demands a "350W PCI Express®-compliant system power supply with a combined 12V current rating of 22A or more."
Otherwise, the two appear to have identical specs except that the PNY offers more out-of-the-box I/O options including a built-in S-Video connection along with DVI-VGA and DVI-HDMI adapters and an internal HDMI audio cable. The PNY seems instantly ready to hook up to an HDMI monitor or HDTV whereas the BFG requires additional adapters and cables. Between the two, I'm leaning towards the PNY mainly because of the included I/O options (I have an HDMI monitor and HDTV I plan to hook the system to), not to mention the great deal I got. But the BFG does claim to require only a 350W PSU whereas the PNY claims to require 400W.
Some web searching has revealed some folks who've supposedly been able to run the PNY card on 380W (http://www.tigerdirect.com/applicat....asp?EdpNo=4588152&csid=ITD&body=REVIEWS#tabs) and even 300W (http://www.newegg.com/Product/ProductReview.aspx?Item=N82E16814133279) PSUs (see GodBunny's 6/3/2009 6:51:33 PM review), but of course all systems are different.
Given my system specs (i.e., Asus IPIBL-LB, Intel Core 2 Quad Q6700 (an energy hog?), 4GB RAM, 750 SATA HD, running Windows Vista Home Premium with Windows Media Center 64-bit edition), would it be wise to push the envelope and attempt to run the "400W minimum" PNY on my modest 350W "maximum continuous output" PSU? Does my PSU have sufficient amperage: DC Output +3.3V 15A, +5V 13A, +12V1 18A, +12V2 18A, -12V 0.8A, +5VSB 2.0A? Where the BFG requires "a combined 12V current rating of 22A or more," does that mean one adds the amperages of all 12V rails (in my case, 18A + 18A = 36A)? And more importantly, even if I can run the PNY, what is the likelihood I will be overtaxing the PSU, shortening its lifespan, and even risking catastrophic power failure that could damage other components? All your words of wisdom are appreciated. Thanks!
