Thanks for your help
Get some other brand since x-connect is terrible. Browse through his forum for the past week. There are many psu threads discussing the same thing.
Troll,
He didn't ask about an X-Connect. He asked about an X2 550W.
If you have some actual insight you'd like to contribute, please feel free to do so. If you want to regurgitate FUD, you should expect to get callled out.
OP,
The X2 550W PSU will be fine with the one X1900, "even if you overclock" :roll: I had one for a time running a pair of 7800GTX's, but the noise from the PSU fan under load drove me nuts. I now use an external semi-fanless 500W unit.
But if you ever decide to go with a pair of X1900's, the PSU won't handle it. Not enough juice on the 12V rails.
As you can see from
this review the X2's rails dropped below spec when used with a pair of X1900's. And I'm sure the PSU fan was spinning like a tornado too.
There's not a lot of "inexpensive" power supplies out there that can handle X1900 Crossfire. As far as modulars go, the Corsair HX620W should. The Enermax Liberty 620W, as someone has already mentioned, should. If you don't need modular, I suggest the Silverstone ST75ZF if you go Crossfire.
