GTX 560FTW+ SLI

[Crazy_Man]

Hello,

I have a set of GTX 560 FTW+ cards that I would like to run in SLI. However I see quite a few forums around the internet with people having a problem with the 24pin power connector melting after they install SLI. From what I can gather from the topics I've found its due to too much power being drawn thru the PCI-E slots and not having a extra connector on the board either molex or sata to feed extra power to the PCI-E slots? I have a Sabertooth 990FX board that does NOT have a extra connector. Should I be worried about the possibility of the 24-pin melting or does this only occur with 480/580s or 3+ cards? Or is somthing else entirely going on?

Thanks for any advice!

I dont think you should worry, the board you have is very good! im sure this "melting" occurred on cheaper boards with sub standard power supplys, the 560sli doesn't draw the same power the 480/580 would need on sli.

i wouldn't worry about it, as long as you have a decent Power Supply you will be fine with that board!

what PSU are you using?

oops just updated my profile to have my current rig on it.

I'm using a Corsair HX-650 but I'm starting to wonder if it will be enough for the 560s and a bulldozer/piledriver chip.

2 gtx560 (not overclocked) = ~ 300w on load (not system, just the 560s), if you overclock them it would probably increase to 400-450w

• On your average system the card requires you to have a 500 Watt power supply unit.

• A second card requires you to add another ~175 Watts. You need a 700+ Watt power supply unit if you use it in a high-end system (800+ to a KiloWatt is recommended if you plan on any overclocking).

i would recommend either the AX750 (minimum and not overclocking) or preferably the AX850 (if you are overclocking) to be on the safe side!

hope this helps
