post #1 of 8
Thread Starter 
Hello, if i get second Asus GTX 560 card will my Antec HCG 620W be enough for those in SLI? I would possibly get that card in pretty good price, that is why i am thinking about this. It is normal 560 and not ti model and my build is not overclocked. Thanks.

My specs are:
Intel i5 2500K
8GB DDR3 RAM
Asus GTX 560
Asus P8P67 EVO
Antec HCG 620W
3x WD HDD

While your PSU does have enough power, I'm not sure about it's quality.
As long as the fan isn't on max all the time or you get infrequent crashes I would say it's enough.

The Antec HCG 620W is a Seasonic OEM PSU. It has incredibly low ripple/noise, and is a VERY good PSU. It would EASILY power two GTX 560s without even blinking.

^Review if you'd like to read it.

Next thing is that my PSU only has 2 PCIe cables that already go to my first GTX 560. I happen to have two 2x molex to PCIe adapters. PSU has 2 cables that have 3 molex connectors on each so can i connect these adapters on any of those molex connectors? Is it safe to use these adapters?

I see. Using adapters seems to be the only way with this PSU? Do i get any performance or safety issues when using adapters? I can also think about new PSU with 4 PCIe cables if there is any suggestions.
