Thermaltake TR2 RX 850watts for my rig?

Hey guys, I have my eye on this PSU:
http://www.thermaltakeusa.com/Prod [...] =1830#Tab0

I Plan to SLI GTX 285's, i'm really concern that the quad rails won't beable support 2x gtx285's. The card seems to need 46amps per card (2 cards = 92amps?), and the PSU can only support 60amp total. Will the thermaltake TR2 RX 850 work, theres not too much reviews on this PSU. Also, the PSU only has 2x 6pins pcie and 8-6pin adapter, and the card itself had 4-6pin adapter. Each card requires 2x 6pins, will i beable to even power these cards? Or, will i beable to use the 4-6pin/8-6pin to make this set up work. Will this PSU even have enough watts for my setup? Heres my current rig:

Vista home premium 32bit SP1 (waiting on windows 7 for 64bit)
Q6600 overclocked (3.0ghtz x9 @ 333, 1.375vcore)
4GB Corsair XMS3 DDR3@1600
EVGA 790i Ultra mobo
xfx GTX 285 (OC 700/1594/1380), another one incoming soon
4HDD:
2x 74gb raptors in raid 0
1x maxtor 320gb
1x 35gb raptor
Coolermaster Cosmos S case.
700watt Rockfish PSU atm... (needs to be replaced)

Any suggestions will help, this is my 3rd pc i built and i really want an SLI setup for my gaming needs. The main reason i'm leaning towards this PSU is because of the discount i get from work. for $120 its a really good value for me compared the other 850wat PSU i can order online.

46A is a recommendation for the entire system, not just the video card.

Under "System Requirements" find:

POWER SUPPLY ADVISORY

NVIDIA MINIMUM POWER SUPPLY REQUIREMENTS

* Minimum 550W or greater system power supply (with a 12V current rating of 46A)
* Two 6-pin PCI Express supplementary power connectors


TheAnimal appears to be correct: 46 amps are the systemwide current load:
the manufacturer's website above does not state the amp load for the card, by itself.

Check this out:

four +12V rails @ 18 amps each


I wouldn't recommend that Tt PSU for 2 x GTX 285s in SLI:

you might be saving money on a PSU that won't work with 2 of those cards!


Go Corsair 1000W (or comparable PSU e.g. PC Power & Cooling).

850 is plenty of power for that set up and i just purchased the TR2 RX-85 for my upcoming build.

This thread was finished in February.

As was already mentioned in your other thread, this is not an 850W PSU. All you need to do is look at the label.
