Upgrades for my build, Can my build handle it?

[ldshaul01]

This is my current build

-Raidmax Horus Gaming Case - Black
-AMD A10-7700K
-Gigabyte GA-F2A88X-D3H
-8GB DDR3-1866 ADATA XPG V2
-AMD Radeon R9 280 3GB - Single Card
-850W Thermaltake SMART SP-850M - 80 PLUS Bronze
-Processor Cooling AVC Liquid CPU Cooling/ Asetek 510LC (Standard 120mm Fan)
-1 TB HARD DRIVE -- 32M Cache, 7200 RPM, 6.0Gb/s - Single Drive

I want to crossfire my video card with another R9 280 3GB card, but I'm not sure my wattage will handle it. Most of the cards I find on newegg say it requires a minimum of 750W for a single card.

Along with that... I also didn't know if my processor could handle being overclocked. I'm very new to this kind of stuff and this is my first build ever. I also just recently bought two extra 120mm fans that are in the mail now.

If anyone could help that'd be great!

At first glance it has enough amperage and wattage to handle 2x R9 280, however, it is a Tier 4 PSU, not built with quality components so it's unlikely it will be able to sustain such configuration for a prolonged time, and forget about overclocking with it, so, while you should be able to use it for the next months in crossfire I highly recommend you to get a better PSU when your budget allows it.

Any PSU's that you would recommend? I've got a little budget now, I'm not too sure what exactly will fit in my case.

How's this?

I'd say either of the EVGA G1/GS, the Be Quiet Power Zone is a Tier three unit so not as good as those two EVGA despite its higher price.
