Is My PSU Powerful Enought For This?

*waits for people to actually READ that review*

Sounds like even jonnyguru not 100% sure....LOL

This demonstrates that if the two rails are in fact separate, there is no OCP (over current protection) on each rail. Outside of a few traces zig zagging across PCB, I couldn't find how even 12V1 and 12V2 are separate, but I'm going to give Seasonic (the OEM for the Corsair units) the benefit of the doubt and say that we seem to have two 12V rails here, neither with any kind of "limit" on them.

ok, the facts. the 3 separate 'rails' draw there power from only two points on the circuit board of the psu - 12v1 and 12v2.

FACT - there can not be 3 rails where there are only two contact points. that means right then that there are either two bigger rails or those two separate points on the board aren't separate at all and its actually one big rail.

now think about it. given that johnnyguru was able to put a 40amp load on a single rail of the 620w psu (50amp max 'combined') and its the same basic design as the 520w, whats the most likely answer?

a) that there are 3 separate rails capable of 18amps each as it says on the psu itself? no way, he wouldnt be able to load it that high on one rail. if it had over-current protection, it would shut down. if it didnt, it would go bang.

b) there are only two separate rails. possible, but still....40amp load on a rail that *should* only hand 25a (on the 620w psu)?

c) there is one single large rail capable of 40a on the 520w psu and 50a on the 620w version. there is no over-current protection on each 'rail', which would be exactly why he could pus such a huge load on one of them.




which is it?

Sounds like even jonnyguru not 100% sure....LOL

The only thing he's not sure on is whether its 1 rail or 2. and i already quoted that text from the review, which actually proves its not 3 rails. aren't you reading my posts either?


now, if speculation inst enough, ask the people who really took the psu apart: http://www.hardwaresecrets.com/article/371/5

What immediately caught our eye were the three separated +12 V lines listed on the label (see Figure 17). As it happens to all high-power units nowadays, Corsair uses a “virtual rail” concept, where they label their power supplies as having separated +12 V rails but inside the unit they are all connected together to a single +12 V rail on the power supply printed circuit board. Unfortunately all manufacturers seem to be doing like this to match the ATX12V 2.x and EPS12V specifications, which require the power supply to have separated +12V rails.

Inside this power supply, however, the wires are separated into only two virtual rails, and not three, see Figures 18 and 19. These two virtual rails are connected the single +12 V power supply rail, as shown on Figure 19 (the red lines are jumpers, i.e. wires). Two groups of wire are connected to +12V1 and three groups of wire are connected to +12V2 (see Figure 18).

No....I was reading the review

Right then..... So Some Say It Will Run And Some Say It Will Be Close.

Im Now Confused As I Still Dont Know If It Will Run Or Not...

HELP!!!!!!

Thanks Again Guys

P.S I Only Ever Burn 2 Dvds At Once Usually And I Use The Other One As A Reader.... I Dont Know If That Makes Any Difference...

P.P.S. I Was Only Going To Buy The 2900 As I Wanted Something That Would Be More Futureproof...

It will run it, not even close. It will not even stretch the legs of that Corsair 520W.

There isnt such a thing as a futureproof pc component. because in 6 months time there will be something bigger and better.

Take my e6400 cpu, i have had it for 4 months and its been replaced already with the e6420 and its £30 less than what i paid.

As others have already said why not get a cheaper cooler quieter 8800gts that will play your games the same.
