frantic_child Posted January 18, 2013 Share Posted January 18, 2013 Hey, Corsair forums. Looking to upgrade my PC in the fairly soon future & need it to be 'fairly' futureproof (i.e. until at least 2015 or 2016). I'll probably be changing out a few components & adding in some, the key bits should look similar to this when it's done: - ASRock Z77 Extreme 4 - i5 3570k - 1tb samsung HDD/250ssd - 8-16-32 gb of RAM, depending on where I get it from & how cheap it is - 2x GTX560 Non-TI SLI However, I'm on the fence about the 2x 560s part. I say this because #1 there's very little material on google relating to the 560SLI on a TX650, it's all the 560Ti & #2 the TX650 doesn't have 4x PCI-E 6+2s, although it does have enough molex connectors to use an adaptor. Would this be considered alright? Would using 2 adaptors (mol->PCIx6) on 4x molex connectors be 'viable' (see: safe)? Thanks for the help in advance.

peanutz94 Posted January 18, 2013 Share Posted January 18, 2013 Well, the 560's may use up t0 150 -190w peak for each card. Then add in the rest of your system components. I would suggest no less than a 750w PSU for that system otherwise the PSU may be running stressed most of the time with just 650w http://www.geeks3d.com/20090618/graphics-cards-thermal-design-power-tdp-database/ Link to comment Share on other sites More sharing options...

Surely that would leave, with a slightly lower end system + more efficient processor (3570k = 77wTDP) + no OCing on the system, about 200w left 'spare' for the PSU? http://www.guru3d.com/articles_pages/geforce_gtx_560_sli_review,14.html What do you think of those findings? Again, thanks for your help so far. Link to comment Share on other sites More sharing options...
peanutz94 Posted January 18, 2013 Share Posted January 18, 2013 Your running a z77 board with SLI which would be considered a high end system. And even they recommend at least a 700w PSu. And 800-1000w if you plan on OC'ing. I guess it's really up to you..But I would suggest no less than 700w too. 200w really isn't that much left over ,especially if you planning on any upgrades in the future.
