Fans = 100W? are you on weed?
even the extreme 3400-4600RPM 59-65dB Delta eats 30W per fan & no normal person can use such loud fans
normal 60-100CFM fans are 5W max

Thanks for the comment. But I do not dope anymore...! :)

If you would have read my full post, you could comprehend, that I have a slightly above then 'noob' knowledge about PSUs, and component requirements.

You yourself have said that the 'extreme' fans use 30W each. What if he mounts 3 of those..? Ok, we remove the 100W for the 'n' fans, and make it 50W..? His overall total -- and ball park figure still remains within 500-550W. Hope I did not commit any sin by quoting that 100W for 'n' fans..?

I'm sorry :(
 
If this is correct the purpose of the thread has been achieved i guess :). (i don't know if this is correct though)

If you're looking for a PSU with better 3.3/5V rails for your hard disk, dont bother. A hard disk sources its power mainly from the 12V rail. In fact those molex-to-SATA power converters don't even have the 3.3V rail on them, and yet HDDs run fine with them.

Lol marijuana is one of the best stress busters, unfortunately it is hard to find good quality in NCR these days. The problem with most users is that marijuana starts smoking them instead of them smoking it (People never get physiologically dependent on marijuana, its physcological ;))

Weed aka grass aka dope aka marijuana aka mary jane aka 'maal' is the gateway drug. Also it is a criminal offense caught with it..or pushing it.! :)

Gateway drug, wonderful if taken occasionally and has to be good quality ;)

Is this true guys....? Where do the molex puppies get the load from. Cannot the PSU dynamically switch the load on the rails..?

What happened when you tried to run the 7 HDDs in tandem on the VX450..?

Sorry should have posted earlier In the case of 7 HDD the pc boots normally, Windows is loaded and suddenly PC restarts with in 2-5 mins without any message or anything. Tried 3-4 times. All the drives were accessible when the pc is booted. So to check the problem I removed a older drive power connector and the system ran fine with 6 HDDs

Where is the connection? Whether a PSU is jointly or individually regulated, it affects only its cross-loading behaviour.

Just out of curiosity, have you tried running the 10 HDD setup on your CM RP 700W? I still think looking for a controller that supports staggered spin-up might be a bit more fruitful than looking for a big PSU.

I know about the cross-loading behavior, but what will happen when the full current carrying capacity of a single rail is achieved ? Also will try using the CM 700 RP soon since it has a 191 watts on the 3.3 + 5 volts rail.

There is some load on the 5 volts rails of the HDD. If we check the specs of a HDD they are like this...+5 volts 0.272 amps and + 12 volts 0.312 amps so both the rails are loaded. The 12 volt rail is loaded more while the time of spin up after that it reduces.

Here a detailed review on the HDD power consumption on 5 and 12 volts it is old one but serves the purpose.
