Default Concerning the Corsair HX620

Okay, so I understand this PSU is a beast, but I have to ask about what I've been hearing, people saying they can run GTX 280s in SLI off of it. I know I'm not the most informed person when it comes to PSUs, but should I believe that it can do so?

I never really intended my new rig to go SLI when I bought the components (the PSU being the HX620 at hand), but I ended up under budget, so the thought had passed my mind but my first thought was "Darn, can't really do that anyways, since in only have 620W..."

but now I'm hearing this and it has aroused my curiosity...

so does anyone know if people are just blowing hot air? anyone here running high end graphics cards in SLI or CrossFire off of their HX620?

Not really a huge issue for me if it can't, but it would be cool
Current Rig:
ASUS Striker Extreme \\ E6850 @ 3.0GHz \\ 8800GT \\ 2GB \\ WD 750GB \\ BFG 800W \\ NZXT Apollo

Soon up and running:
ASUS Rampage II Gene \\ Intel i7 920 \\ EVGA GTX 275 \\ Corsair 6GB 1600MHz 7-7-7-20 \\ WD Caviar Black 640GB \\ Blu Ray Drive \\ Corsair HX620W \\ NZXT Rogue

My System Specs


For one thing, it only has 2 native PCI-E 6+2 cables. You can use the molex to PCI-E adapters but I recommend not to do that (just because I like cables meant for their job). I've heard that it is possible, but you'd be pushing it to its limits. Having a PSU operating at 80-100% load for long duration periods (such as folding and gaming for long periods) would decrease the life expectancy of the capacitors in the PSU.

If you do plan on using SLI, you may want to switch to the TX750 or HX750 if you really want to go modular. Those are both outstanding PSUs. Both of those have 4 PCI-E 6+2 power cables, so providing power to your two GTX 280s would be much more reliable than using the adapters.
