Single rail is theoretically better as it means that you don't have to worry that you are spreading your load evenly over all the rails.

Thanks Dicecca, thats exactly what I wanted to hear.dicecca112 wrote:well http://www.jonnyguru.com/review_details.php?id=135 he's the guru.
From a quick overview, I can see that its not as efficient as the HX520, but the rails are just as stable. remember the High end is the HX, the middle grade is the VX (even though they market it as budget
Either PSU would be fine. You want modular then go HX.
The former models are 12V single rail PSUs.ibleet wrote:With Corsair being such dependable and popular PSU's, I was wondering about the 450VX and the 550VX and how they compare to the current 520HX and 620HX units. I noticed the new ones have a single rail, as opposed to the 3 rails on the former models. I also noticed that the new PC Power & Cooling Turbo-Cool 1200 runs on a single rail.
There's no significant fundamental change in model designs, they are all 12V single rail PSUs.ibleet wrote:Can someone explain the positive and negatives of the different models?

The 550VX design is slightly improved over the 520HX in output efficiency hence the rating change from 520 to 550.ibleet wrote:was thinking the same thing Dan, thanks. But I'm still wondering why! I'm curious that way.
Why would I spend more for the 520HX if there is a possibility that the 550VX is better and cheaper? That is exactly what I am trying to find out. You don't have to sell me on Corsair...I don't even consider other brands.
As mentioned above the HX and VX series both indeed have 1 rail if you get down to it.ibleet wrote:With Corsair being such dependable and popular PSU's, I was wondering about the 450VX and the 550VX and how they compare to the current 520HX and 620HX units.

As to which power supply is better? I'd say the HX520W is better than the VX550W because of the modularity and it is a little bit quieter. The VX550W is nearly 40dBA at full load and the HX520 is nearly 36dBA, so there is a 4dBA difference between the two when they are maxed out. Both use 105C Industrial Capacitors, are rated at 50C and have one rail.ibleet wrote:Can someone explain the positive and negatives of the different models?

and modularity as mentioned. to keep that cable mess clean the modularity is awesome.

(<- Clickable)The main problem with you is that you had no clue to the subject but already are expert at how the subject should be told, and obviously I should be required to do it using your reasonable and believable method.DMB2000uk wrote:Can't you just explain to him why instead of proving why you are right?
There're 3 12V connections from a single 12V power rail. The PSU literate label below showed 520HX with 3 main 12V connections originating from a single 480W 12V(40A) rail. In exactly the same way which 3.3V and 5V are originating from a single 140W rail.DMB2000uk wrote:There are 3 12v rails in the PSU, but their output has been tied together to effectively make them as one rail.

As many already mentioned, it most likely boils down to whether you like modular or not.ibleet wrote:Ok, now I'm totally confused...This is taken directly from Corsair's website: "Triple 12V Rails provide independent reliable power to the CPU, video card and other components with a combined rating of 50A (40A on 520W) maximum! Advanced circuitry design that automatically enables power sharing between the triple +12V rails in an event of overload on any single +12V rail."
Nein claims the HX series has 1 rail and Apop agrees as follows: "As mentioned above the HX and VX series both indeed have 1 rail if you get down to it."
OK so Corsair's site says their HX PSU allows power sharing between the triple +12v rails. So, if any single rail is overloaded, the power can be transferred to one of the other 3 rails.
Now what throws me is the term triple, followed by the word RAILS, with Rail being plural. Not to mention the transference of power between the (3) rails. So...how exactly do you "get down to it"? And why would Corsair market the HX this way if it had only a single rail? Are we just talking semantics here?
I wish we hadn't opened this can of worms, but unfortunately, we did.
I supposed using factual garden-variety PSU common sense for your answers not allowed as it lacked equal entitlement and merit. Only claim, belief, faith, and reasonable/believable permitted?ibeleet wrote:Regardless of what you say, I feel that my questions have merit and I'm entitled to ask them.
