Will a 500w or 550w PSU work for this work even though it says minimum 500w? How much power will it use and will 500w also be enough to run my other components?

Such recommendations are for people who don't know how to read numbers and do simple math or don't want to do it. These recommendations don't matter and the wattage of a PSU doesn't matter.
What matters is +12V amperage because this is the power used by CPUs and graphics cards as well as some other components such as hard drives and most fans. Some 350W PSUs can handle a 7850 with a low power CPU suc has an Ivy Bridge i3 or an AMD Trinity quad-core APU with its IGP disabled, some 600W PSUs can't. You have to check the +12V amperage of a PSU and find the +12V consumption of your computer to find out if a PSU is good enough.

out of the 2 PSU which do you think is the better choice?

The Antec has an annoying triple rail setup that is overkill anyway and the Rosewill is also way overkill. I don't like them as a brand much for PSUs either (although I do like numerous Rosewill cases very much), but I admit that that is more subjective.

<<Is sensing someone doesn't know the value in the superflower designed Capstone unit
i mean its like 65$ in the combo technically, so its actually alot more affordable. Unless you are going through with the possible MIR(as corsair is slow to the gun on those) Capstone holds one of the highest price to performance ratios

The problem is that it is far overkill on the +12V rails. You could literally halve it and still be plenty. Way overkill PSUs can be a detriment to a system. I might consider that PSU for a Radeon 7870 Crossfire build, but not for a build with with a 7850, not even with such a fairly high-power CPU as the FX-4170.
EDIT: Also, the Corsair unit is still cheaper.

cheaper by like 3$(13 if you get the rebate(corsair unit has shipping cost)). part of the price also is reflected vs the warranty periods(3 vs 5 years)

if you want a great psu
if you're willing to pay a bit more for a 7870
would also recommend at least paying 5$ more for the extra gb
why is that PSU Discontinued?

Like I said earlier, I think that I could make a better recommendation than any of these.
http://pcpartpicker.com/part/corsair-power-supply-cmpsu...
$25 is about as cheap as it can get and still get such a PSU as this. The Rosewill doesn't come close in value for OP's situation.
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Those two are my recommendations if OP wants a five-year warranty.
I haven't checked yet, but I'll see if a favorable Rosewill model is also available here without a way overkill +12V rail configuration.

I would disagree, the cx unit is far more likely to crash before the capstone unit. albeit old, theres a reason why communities listed the capstone unit a tier higher than the cx unit
for further comparison the capstone performs similar to the corsair tx750m but at a higher efficiency rating, lower cost.

It's a higher quality model than the Corsair CX series, but it is not oriented towards OP's power usage. The 450W Capstone would be better for OP, but it's also still overkill.

I would not think it would underload itself. I mean its similar to people who have SLI/Crossfire builds. When you are not gaming, you turn off sli/crossfire, so where would the rest of the power go. its being unused for a period of time, but the gap in that situation would be significantly bigger gap then a single card build with a slightly larger psu. OP has an FX-4170 with an aftermarket cooler with a tdp of 125w(note that amd builds have a higher power consumption), Most likely with the intention to overclock as well as a 7850, which may as well be overclocked too. the load of the two parts alone should at least strain more than half of the Capstone unit when under load. bringing the build down to a 408w(cx 500w level) is pretty close to the cap alone.

I think that the BP550 Plus is fine,aside from having great reviews,it also has 3x12V rails that sum up to 69 Amps,69 amps has the potential to output 828 watts on the 12V rails alone,whether or not this is possible remains to be seen with the other components the psu is built with but from the amps it seems great.
also anandtech tested the 7850 for it's max power consumption and it,along with the rest of the system drew only 385 watts.so even disregarding that this power supply has the potential to output more than it's rated amount,the psu should be fine.
I'd recommend switching to the samsung f3,it is a great quality hdd.
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
I'd also recommend switching to a phenom x6.
http://www.cpu-world.com/Compare/320/AMD_FX-Series_FX-4...
check the performance tab on there it compares the phenom x6 to the fx 4100,and the phenom wins almost every time.
and the cost is almost the same

multiple rails aren't additive. Antec has the OCP set to 36 amps on the unit. it cannot go past that mark much.

The way that PSUs are rated for wattage also varies from model to model, especially with different brands. Besides that, in gaming, a stock 7850 uses under 130W and even overclocked and overvolted, it rarely breaks 150-160W. The FX-4170 is unlikely to go far past 120-130W. Altogether, OP's build would probably be more like 225-275W on the +12V at stock in gaming and around 250-315W overclocked in gaming from the graphics and CPU. The rest of the system won't load up another 108W or so and the closest that it would get to that would be start-up and stress testing.
At stock, even the CX 430 could handle this system, although I think that that would be pushing it at this point and I'll retract that recommendation. I still recommend my other suggestions.

The FX-4170 beats the Phenom II x6 1100T, the best Phenom II x6 in gaming performance. The 4100 doesn't come close. In gaming, the Phenom II x6 1045T would be crushed and even the FX-4100 would beat it. Don't make gaming recommendations based on non-gaming benchmarks.
Samsung's HDDs aren't great since they sold out to Seagate. Western Digital Caviar Blue is currently better.
