Hello Long time lurker first time poster .. I'm thinking of getting 2 gtx 7900 cards and i'm wondering what kind of psu to get? I have an Athlon 64 4800+ CPU 4 ram blocks, and have to be sure they will have enough juice so any suggestions would be greatly appreciated. :speed:
Looking at some power supplys at newegg.... I found this SLI ready 650 Watt powersupply... I'm sure it'll power that beast of a computer, I'd read some reviews on it through this link and see if you like it, $140 too, better then alot i've seen http://www.newegg.com/Product/Product.asp?Item=N82E16817159056
Take a look at this list. Any of those would do, and I would say be VERY careful with PSU's for such high end cards. Even ones rated at up to 600/650 watts by good known brands have recently had problems keeping up with high end SLI rigs. http://www.slizone.com/object/slizone2_build.html#certified_powersupplies BTW, I have a EPSILON FX700-GLN 700W arriving on monday. Just starting to see a few signs of underpower on my Enermax, and for the money thats the best PSU I could find. 4x15amp rails (60amp max) looks tastey
I saw something on newegg saying 1 kilowatt of power! on the right side of newegg on an advertisement.. so I think theres Higher
Hi guys, I didn't want to open a new thread just for one question, and since you're talking here about power supplies... mine is a 430 W and it has +12V 14A and +12V 15A does this mean it has 29 A on the +12V rail? Should this be enough for a 7900 GTX without SLI? I'm using it with a 6800 GS right now and is giving me no problems
well for a 6800GS a 370w doesnt give me problems either. 7900 is a bit step ahead though, so a more powerful PSU will be needed.
you wont need something that meaty, I reckon a Seasonic 600watt unit will be enough to power your beast. and for the third time .... http://extreme.outervision.com/index.jsp enjoy
seasonic is one of the best psu's there are, and that tagan is awesome mike. but why dont you go with a pcp&p?
The PC P&C are great PSU's but way overpriced, im not spending that much on a PSU. My enermax is just starting to show its limits when i overclock with these 7900's, but the FSP 700watt should do me fine. Looks like a very good PSU indeed. Cant moan at 60a at all, and every review ive read has said its one of the best. BTW, Tagan are very good too, i just build a rig around their 480watt one, very nice indeed, but the most powerful one i could see was a 580watt, so not enough for my needs im afraid.
SaintEpsilon, Here’s a link to an interesting article about the ridiculous power requirements with the new video cards- http://www.extremetech.com/article2/0,1697,1932958,00.asp I have actually experienced these problems first hand. After going through an Enermax and a PC Power and Cooling 510/SLI, I finally gave up and bought a PC Power and Cooling 1000Watt for the machine listed below (my two Evga 7900GTX’s Super Clocked should be up and running by Tuesday). I’m also going to be ordering a second 1000Watt for my ATI 1900 series Cross Fire setup. Asus A8N32 Deluxe/BIOS 1103 Athlon64 X2 4800+ Corsair TwinX2048Mb-3500LL Pro 2x e-GeForce 7800 GTX KO ACS3 Edition Sound Blaster X-Fi Fatal1ty FPS 2x WD 74Gb Raptor (RAID 0) 2x Seagate 80Gb (RAID 0) Plextor Premium Plextor PX-716A PC Power and Cooling Turbo-Cool 1KW/1000W Silver Stone TJ03 Windows XP Pro/SP2
repapips2004, My Nvidia setup has been pretty much trouble free. I cannot say the same about my experiences with Cross Fire- http://www.planetamd64.com/index.php?showtopic=19452 Right after I went through with the RMA process to send everything back, Asus released a BIOS on Friday that supposedly fixes the problems. My brand new A8R32-MVP Deluxe, 1900 Cross Fire Edition and 1900XTX should be on my door step in about a week so that I can try this all over again. The case got sent back for good, I cannot believe how poorly the panels fit on that thing. Pretty sad for a $365.00 case.
