hay guy's im just about to buy another super clocked gtx 460 1gb so go sli for bf3 with a phenom 1090t there will not be any overclocking just stock with a water cooling cpu loop but i have slight worrie about power my current psu is a coolermaster 600w silent pro gold but the psu itself give's you 2x 6pin pci-e and 2x 8pin pci-e so it must be made to run some power hungry gpu's ???
I'm no expert but i think you might be pushing it a little much with the water cooling and 460's in sli.
I am not the man who could give you an answer but http://www.bit-tech.net/hardware/graphics/2010/07/12/nvidia-geforce-gtx-460-graphics-card-review/11 that the power consumption and thermal review from bit tech and for a PSU calc i usually use this
I very rarely say this as a lot of people vastly over inflate their needs when it comes to power requirements, but I'd say that you would be pushing your luck there. If someone was doing a scratch build with 2 x 460 GTXs I'd be insisting on a 700w PSU as a minimum.
depending on psu efficiency, your rig minus the w/c kit is going to pull around 420-470 from the wall with sli 460's...more if oc'ed...with a heavy load on the rig mind you. so figure that is hitting 375-420 out of the psu... i'd say ur psu is fine. unless ur pump and w/e take more than (edit: can't math today)180 watts, you should be good... any higher and you will be running 100% load, and if you do that often enough, well...you know the deal...might want a beefier unit at that point
The following review shows the power consumption of a i7 965 / X58 overclocked to 3.75 GHz with GTX 460's in SLI: http://www.guru3d.com/article/geforce-gtx-460-sli-review/15. It shows 433w under 100% GPU load. As they state at the bottom of the page, add another 100w-150w when the CPU is under 100% load as well. This next review shows the power consumption of an i7 970 rig overclocked to 4.33GHz with GTX 460's in SLI: http://www.kitguru.net/components/graphic-cards/zardon/evga-gtx-460-1gb-superclocked-sli-review/13/. This review doesn't show total system power usage, it shows a single EVGA GTX 460 Superclocked drawing a maximum of 175w under Furmark (less whilst gaming remember) and 348w for two in SLI under Furmark. These results measure the power drain directly from the GPU power inputs. I run 2 Inno3D 768mb GTX 460's in SLI with an Antec TruePower New 650w and an i5 760 @ 4.0GHz. I reckon you will be absolutely fine given the quality of your PSU.
nice find fingers...cant remember the last time i saw a gpu only power consumption... and i'm no w/c kit jedi, but i doubt they use 150+ watts right?
It's a great PSU and it does have all the correct cables. Yes you might be pushing it if you were overclocking but as you aren't you should be okay.
Btw the Silent Pro Gold is a tasty piece of kit. My cousin used one in his build. Fantastic power supply. Good pick.
