Now, my question is will a crossfire of HD 4850 work with this power supply. and I do not want to do Overclocking

No you need atleast a 650 W Power Supply or more so that it would be quiet
Go with the Corsair TX - 650W. It has 5 years warranty. It gives a TX 650W silent power supply with its fan 12 cm, but also economically active PFC with a 0.99 and an efficiency close to 85%. Connectivity is no exception, with 8 S-ATA and PCI-Express 2.

At least 650-700W you need. It runs well, it looks after such other opinions on other brands

Even a Corsair HX 520 would suffice No need for a small 700w CrossFire. It is not SLI or consumes much. The CrossFire take in less than 300w load. It is still not bad for the rest of the system

The problem is that the 500W power supply will always be in charge and almost always be limited. Even with a very good gear it will break its days. So better opt for 650W to be not at a risky level.

4GB 1066 OCZ fatality (upgrading to 8GB)
2.7 AMD 7750+
Crap Mobo (going to get Foxconn A7DA-S)
1x4850 sapphire 1GB OCD( have two but need answers)

also have a SS-650HT (seasonic)

I just wanted to know if this powersupply will be able to handle running two brand new 4850's it is kinda old still 650 but should i get a new one
