Hi

I want to upgrade to 2x 5850 and I am not sure if my Corsair 620W HX(2 years old) can power xfire 2x5850(probably I will OC them).

My system is:

i7 920 4.0GHz
ASUS P6T
OCZ DDR3-1600 6GB
ASUS GTX 295 OC(10%)
Corsair 620W HX
Thermaltake Spedo Advance

As you can see the Corsair 620W is capable of handling a GTX 295 OC(10%) and i7 920 4.0GHz(I have this system for more than a year and it is absolutely fine with this PSU but I don’t know how much power 2x5850 OC will need)
 
The answer to your question is yes! :)

Here are the official power requirements for the new ATI Radeon HD 5850 and HD 5870 video cards.


ATI Radeon™ HD5850 System Requirements:

PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard

500 Watt or greater power supply with two 75 watt, 6-pin, PCI Express® power connectors.

600 Watt or greater power supply with four 75 watt, 6-pin, PCI Express® power connectors for ATI CrossFireX™ technology in dual mode.


ATI Radeon™ HD5870 System Requirements:

PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard.

500 Watt or greater power supply with two, 75 watt, 6-pin, PCI Express® power connectors.

600 Watt or greater power supply with four, 75 watt, 6-pin, PCI Express® connectors for ATI CrossFireX™ technology in dual mode.

The power supply recommendations are for an entire pc system.

The 5000 series cards are actually more power efficient than the 4000s from what I've read, so you should be fine...plus the fact that you invested in a good quality PSU to begin with. I personally don't like taxing my PSU that heavily though as it is more stable the lighter the load on it is and I like to leave a little headroom for more fans, drives, whatever. If I were running your system I'd probably sell the 650 and save a little up for the corsair 750w. That's just me though.

I am using same PSU for crossfire 5870's overclocked and a 860 @ 4,01 ghz and it performs perfectly fine at all the tests ive been torturing it with. Its more than enough :)
