TX650 vs HX620 for Crossfire?

[fsh42na]

Which of these power supplies would you recommend for Crossfire using:

(1) HD 4850 x 2
(2) HD 4870 x 2

I also have a TX 750 coming in that is already Crossfire ready (4 x 6pin pci-e cables)
Corsair is sending me a couple of extra 6 pin pci-e cables to use with my HX620.
The TX 650 has about 52amps on a single +12v line
I"ve heard that the HX620 is actually has a single +12v line also, but I couldn't find any info on amps for it


Thanks

The HX620 has 50A available on the +12V rail. The TX650 has 52A but is not modular.

To be honest, they're basically the same PSU, one modular and one not.

For 4850s in Crossfire, you could use either of them

For 4870s in Crossfire, I'd recommend the TX750.

if you dont need modular then go for the 750TX you can pick it up for around 100 bux.

Redbeard,

Thanks for the quick reply! Corsair customer service is the best. Your power supplies are all I use
