Thor. Posted April 12, 2012 Share Posted April 12, 2012 (edited) I just inherited a large sum of Money do to Loss of my Grand parents :sad: my budget i set aside for myself is 2000$, although i could go further then that.In memory i am going to treat myself to something awesome, another 7950 and a 1500watt psu. Also getting another 24inch viewsonic to put in Eyefinity :biggrin: Yup going full out. Any psu recommendations.. Price range is not a issue. I just want to know what is the best you can buy..Let the debate begin. Remember it has to be 1500watts :biggrin: Witch sometimes can be hard to find. I'm not to sure what the best is actually, i usually just stick to what works :tongue: Edited April 12, 2012 by Thor. Link to comment Share on other sites More sharing options...
hoofhearted4 Posted April 13, 2012 Share Posted April 13, 2012 why in the hell do you need a 1500W power supply? dont you already have a 1200W PSU? a 1500W would be like double what youd actually need Link to comment Share on other sites More sharing options...
Thor. Posted April 13, 2012 Author Share Posted April 13, 2012 (edited) No just 1000Watt, and i don't even think its Crossfire ready, i bought it nearly 2 years ago. So i am just playen it safe. I might add 3 way crossfire one of these days. Each card is recommended to have atleast a 500watt psu, 3 cards equals close to 1500watts, but i douubt they use that much.Just need the head room when i do cross that path.

hoofhearted4 Posted April 13, 2012 Share Posted April 13, 2012 (edited) well i messed around with some numbers, and two 7950s with an OCed 3960X CPU (which uses more power then your CPU, which is an 1100T IIRC?) and tons of fans and with everything at 100% max load (which youll probably never do), 100% CPU TDP (which is says youll never reach) several HDDs and SSDs with 32GB RAM and 4 things charging from USB drives, and a fan controller, Cathodes, still only use 829W. with all that on your PC, Tri SLI with 7950s, it predicts 954W and for Quad SLI it predicts 1079W for comparison, i changed it so that it was an 1100T OCed what would be considered a decent amount (4.5GHz) 1 HDD, 5 High Performance Fans (which doesnt make much difference what type you select) recommended Load and CPU TDP settings, no cathodes, but still fan controllers, and the USB charged devices at 4, basically turned it down to what i would suspect would be your average build, 7950s SLI : 608W7950s Tri SLI : 721W 7950s Quad SLI : 833W even if thats under estimating it slightly, thats still well under even a 1000W PSU. test out the numbers yourself :) Edited April 13, 2012 by hoofhearted4 Link to comment Share on other sites More sharing options...
Rennn Posted April 13, 2012 Share Posted April 13, 2012 But you don't want to max out your wattage. Try to keep 200w or so unused. Link to comment Share on other sites More sharing options...
Thor. Posted April 13, 2012 Author Share Posted April 13, 2012 (edited) I have other things like LED fans, hardware. monitors. and so on. Like this calculate everything that uses the psu in general. Remember its not just motherboard, hard drives, its the external stuff aswell, as a whole unit. http://www.thermalta...utervision.com/ I have been working with pc for a good 12 years now, well ever sense my first build back in 2000. I had some builds that wouldn't start at all do to the smallest of things. It could be anything. Edited April 13, 2012 by Thor. Link to comment Share on other sites More sharing options...
hoofhearted4 Posted April 13, 2012 Share Posted April 13, 2012 (edited) I have other things like LED fans,caluculated for that. i said that. LED fans use like 1 or 2 more Watts then a regular fan. and the fans i calculated with were "High Performance" fans, which use more Watts then LED fans, according to that calculator monitors. monitors dont connect to your power supply, i assumed you knew that, Remember its not just motherboard, hard drives, its the external stuff as well, as a whole unit.whatever you think i didnt add, still isnt going to add up to anywhere close to 1000W, considering a Quad SLI Rig was still ~150W+ under your limit. what your going is ~400W under your limit! nvm a 1500W PSU. also, the calc you linked to is the same one i linked to.

Thor. Posted April 13, 2012 Author Share Posted April 13, 2012 (edited) Yes i know that, All i am saying is i rather have more headroom then i need then none at all. thats how i built my last pc. I even saved my psu for atleast 2 builds already. Although this ones getting quite cramped for my liking, well even my case barely has room for a 7950 lol, Downfall with the antec 900 cases is that the psu is at the botton. So you have to stretch the cable across from psu and the gpu and the rest of the hardware. I'm very tempted on getting a new case. Also on the list,I'm might do that.. :biggrin: you can't change me i like overkill, thats why i am very tempted on going triple crossfire, another draw back of the antec 900 series is it only supports sli or crossfire.

Fonger Posted April 13, 2012 Share Posted April 13, 2012 I have other things like LED fans, hardware. monitors. and so on.your monitor(s) runs off of your computer's psu??!!??!! Link to comment Share on other sites More sharing options...
