i saw most of the rackmount servers with latest cpu's and lot of ram and hdd require power 450w-800w but most of the colo providers provide 1amp 110v power as default for 15$(average) and maximum of 3amp 110v for 45$ (average) upgrade on single server colo. so how the budget dedicated server providers who have these latest servers provide dedicated servers for a very low price. and how you guys colo your server which needs lot of power when colo providers dont provide that much power. example, E5-1650v2 processor alone eats up upto 150w (as mentioned in intels website).
The offerings could be two-fold. The companies that you're seeing are simply reselling the dedicated server from another provider and don't pay a colocation/amp usage fee. The reason some of the larger providers can charge less is because they don't pay $15-30 per amp because they have large scale operations where they're leasing 1,000's of amps to power all their machines.

The servers probably draw less power than you are calculating. Having an 800w PSU doesn't mean that is how much is actually going to be drawn, especially if mostly idle. Our servers with a newer CPU and 2~4 drives draw less than 1a. Older servers are less power efficient. I think some of our backup servers with 12~16 drives, or some very old dual CPU servers draw about 2.5a.
E3's generally use around 0.5A, whereas dual E5 26xx configurations (aside from higher TDP models) usually use a bit under 1.5A under typical loads for the whole server. The E5 16xx are higher TDP, but probably still easily under 1.5A. The 16xx are less common because they're harder to source, and their high TDP make them unsuitable for 1U use, thus taking up more rack space as well.

Yea most data centers get huge discounts on power and electric because they use a lot of it and pay a lot at the end of the day because all the power they use a truly adds up we just can't calculate it to the point where we will see the fact of how they are able to offer at such prices.
It depends which Datacenter you go with, some are cheaper than others! You also need to remember that the power usage can change depending on how much resources are actually being used.
There are certain regions in the country that can get power at a much lower price. IIRC, Facebook built data centers in the pacific NW based primarily on power costs. They were using mostly coal power, which drew negative attention, but ultimately brought their costs down. So 1) they're getting power for a lower price and 2) they're oversubscribing because customers don't always use all their allocated power.
Verdict? Low end providers are complained about regularly here on WHT. Their business models often demand razor thin margins, and when something goes wrong, it's a disaster because someone's gotta pay for the fixes and no one wants to be that person.
