Corsair TX850W

I have pondered hard over what PSU to buy and the TX850W seems to keep popping up.

At present my current MB has a single PCIe x16 slot, but I am considering a more expensive board with 2 such slots.

Now my GTX 260 has a pair of 6 pin connectors and I figure SLI with that class of card is a cakewalk.

If I get a dual GPU card, that is one way to more performance in a single slot and I believe the TX850W can do that without even breaking a sweat.

Searching with Google I saw that greedy GTX 580 users tried this model and it did not choke with SLI.

I am more of a 2nd bin user, so the cards I see are pairs of 6-pins so I think the TX850W is suitable.

The 260 needs 2 6-pin connectors with a free 15.2W each. X2 would be a grand total of ~61a... as the TX850 has a single 70a rail you will be fine.

That PSU will run up to 2 GTX 580s in SLI. 2 GTX 260s Draws less power. A quality branded 750W should handle.

even a HD 6990 can run with a 700W PSU.

750W is not underpowered you just have no idea about what each component consume anyway the TX850W is great, you're good to go.

the old HX seem to be respectable and durable, the TX a newer series

I saw one review of the TX850W run it with 2x GTX 580 cards and no problems, they ran the PSU up to nearly 1000W and it did not choke.
