For The Price 390 From Coolermaster is a Steal ,I Will Post You The Amp Rating Of all the different Voltages Tommorow

216W on the 12V rail = 18A total.

The Corsair has 30A in contrast; plus its rated at 40 deg C vs the 25 deg C on the CoolerMaster.

beg to differ.

400 - 130 - 25 = 245/20 = ~20.5A *cough* *cough*

Paying 3.3K for a PSU with 21A on 12V is absurd :S I'd rather buy a VIP 500 or a 600 for much cheaper prices.

could you enlighten us lesser mortals on how exactly you arrived at those figures? :ashamed:
 
OMG sidhu you cannot do basic maths :| you really think you can load that corsaid with 30A on 12V and still expect for the comp to run? hilarious :P:P:P

400 ( peak power ) - 130 (peak 3.3+5) - 25 ( -12V and 5VSB ) = 245.

@sidhu

390 - 160 - 22 = 208/12= 17.4 :)
 
its a typo :P its 12 not 20. anyways I'd hope you figure it out when you see 245/20 != 12.something
 
I will not debate on how much 3.3 and 5V is used since it varies from system to system. that is my benchmark and how i judge power outputs :)
 
CM 390W - 160 + 216 + 12 + 10 = 398W

Corsair 400W - 130 + 360 + 9.6 + 12.5 = 512W

Can any1 explain why Corsair is advertising 512W unit as 400W ? Sunny ?
 
lol max the PSU can deliver is only 400 not more. its more like permutation n combination, combination of all those rails added together will never exceed 400.

^^ not really. Most good SMPS can supply more power than what they are rated for. Of course, only occasional (read if there is a sudden spurt in power demand) and not on 24X7 basis.

while I am not too sure that you are wrong in your assumptions, I have a question. why have you assumed that CX400 can only supply around 240W on 12V rails because 3.3V and 5V will always be used to their full capacity?

Almost all PSUs are made with an assumption that rated 12V load will be reached ONLY if their are rails are not under their full load. This is how HX620 is rated for 600W on +12V rails. The assumption is that modern systems don't require much from 3.3V and 5V rails. Hell, they don't even require this much from +12rails but the extra juice is there just as cushion.
 
and pay monthly installments of high electricity bills, un-explained hdd crashes and system unstability :cool2: :P :(

actually the corsair 450 vx can handle more than 620 w peak power, so its fair to say that the 400 vx will easily supply 500+ watts.But they should price it at atleast in the 2.6k range
