I want to use this PSU Chieftec GPS-600A8 600W. Is it good enough? Any better for similar price?

I'd like to order now.

Two 6pin connectors....so any 6 pin or 6+2 will work. Also take note that the GPU has a minimum requirement of 25a on the 12v rail and a 500w psu.

As much as I like supporting smaller companies, I believe a PSU is something you must obtain from a good brand such as:
XFX, corsair, seasonic, cooler Master, e.g.

Look at the Corsair GS 600w

It is sufficient. However if XFX Pro series is available for you, check out the 550W or the 650W depending on which one you want. And it would be much better than the chieftec.

What exactly makes it worth paying twice the cost when the only difference I noticed in specs comparison is one less safety feature and blue led lighting inside and one more floppy disk drive cable?

As far as I am aware, the PSU is the only component when faulty and of poor quality, can take the entire system down with it, permanently. Rare but it does happen, also PSU's sometimes don't go out quietly if you know what I mean. I knew a friend who's OCZ PSU essentially blew up.

rvilkman is more aware of PSU's than I am, but I'm sure he can address why a good PSU is very important better than I can.

What I want is: buy a cheap psu until I get better one then I might use two psus at once but if not I'll get at least 1600Watts
but there is no option for Me such as entire system takedown because I will have 6 7950s
I want to use 1 or 2(if possible) 7950s on this cheap psu until that happens though.

Not sure this is possible, you can only attach one PSU to the motherboard and why do you need 1600Watts?

Same question to you: why exactly is it better to pay double the price?

6 OCed 7950s take 1500Watts??? Or am I wrong?

Crossfire and SLI only support 4 cards. So the 6 cards is not possible. And you need X79 platform to support 4 cards, unless you run 2x 7990's. This adds to cost, also running 4 cards does not necessarily increase performance, scaling becomes horrible past 2 cards and you will experience negative scaling in many cases. On top of this crossfire and SLI drivers running 3+ cards becomes a headache.
Also if you run really high resolutions like 4k monitors then the HD 7950 would not be too great because the Memory bus is 380 bit and commands 3GB(Vram does not stack so you will still only have 3GB)
So in theory 2 R9 290x would perform better due to better Vram handling with 500bit bus e.g.

To be honest, if you were seriously considering to purchase 6 GPU's then you are far from read enough on computers.

thx a lot 4 ur gamin advic but Ima gpu mine scryptcoins wiv dis rig so d abov is irrelevant 4 me
I wont be usin crossfire and I only care about the cards.Everything else cheapest
Unless ur sayin that I cant use 6 gpus anyway on a h6del board with celeron 1620 cpu but even 8 gpu rigs exist

So why exactly should I consider according to you that twice as expensive PSU

haha, I have already said this:
A cheap rubbish PSU has a chance of going wrong, blowing up, destroying everything in your computer.

An expensive PSU has a FAR less chance of blowing up, and taking everything down with it.

Remember these situations are rare but they do happen.

haha, I have already already read this :D 
the same question in other words:
Why exactly a cheaper has this chance?
Also there is a warranty?Does it cover that?Does it cover whole system wreck?

This, I cannot answer, sorry.
Also the chances of it wrecking the whole system is VERY rare. It will usually just fail itself.
