Thats why Im trying to convince him to get the Corsair

I made the same mistake last August and Wasted $1800 because of stupidity. Ony until now I was able to recover to get a new computer

What is "multiple +12V rails" really: In most cases, multiple +12V rails are actually a single +12V source just split up into multiple +12V outputs each with a limited output capability. There are a few units that actually have two +12V sources, but these +12V outputs are either combined into one or split into four or more. To be clear: These REAL multiple +12V rail units are very rare and are all 1000W+ units (Enermax Galaxy, Topower/Tagan "Dual Engine", Ultra X3 1600W, etc.)

Do multiple +12V rails give me "better stability", etc: Nope. Not at all. The components that spilt up the +12V into multiple +12V rails doesn't do any kind of regulation, filtering, etc. They just split the source up into two, four, six, whatever +12V circuits and has a logic that "shuts down" the PSU if any of the circuits exceed a particular current.

So why split the +12V rails up?: Well.... 240VA+ is a lot of power. Some shorts aren't always detected by short circuit protection if there's enough resistance in the load. These "slow burn" shorts are enough to melt insulation and cause a small fire.

Why do some people FUD that single is better?: Because a while back, some PSU companies followed EPS12V specifications, which is for servers, not "gamers", for quad +12V rail PSU's and put ALL of the PCIe connectors on one of the +12V rails. The +12V rail was easily overloaded and caused the PSU to shut down. Instead of correcting the problem, they just did away with the splitting of +12V rails altogether. Multiple +12V rail "enthusiast" PSU's today have a +12V rail just for PCIe connectors or may even split four or six PCIe connectors up across two different +12V rails. The rails themselves are capable of far more power output than any PCIe graphics card would ever need.

But some people claim they can overclock better, etc. with a single +12V rail PSU: B.S. It's a placebo effect. The reality is that their previous PSU was defective or just wasn't as good as their current unit. If the old PSU was a Coolmax with four +12V rails and the new one is a PCP&C with one +12V rail, the new one isn't overclocking better because it's a single +12V rail unit. It's overclocking better because the old PSU was crap. It's only coincidental if the old PSU had multiple +12V rails and the current one has just one. The only "problem" with multiple +12V rails is that when they have a +12V rail overloaded, the PSU shuts down. Since there are no "limits" on single +12V rail PSU's, you can not overload the rails and cause them to shut down..... unless you're using a "too-small" PSU in the first place. Single +12V rails do not have better voltage regulation, do not have better ripple filtering, etc. unless the PSU is better to begin with.

Good thread on the matter: http://www.overclock.net/power-suppl...ails-work.html Pay particular attention to DuckieHo's drawings.

The Enermax Galaxy has two +12V sources. One is split into two for the CPU via each of the 4-pins in the 8-pin EPS12V connector. The other is split into three. One powers the +12V on the 24-pin and one of the PCIe. Another powers all of the fixed Molex connectors and a second PCIe. The third supplies power to the modular interface.
Single rail isn't "always" better ... many are just marketing ploys anyway...

Check your sources... they're lying to you.

Although the Corsair is a FANTASTIC power supply, it's not fantastic because it has a single +12V rail.

"Trapped power" is a myth created by marketing types. It doesn't even apply to 90% of the multiple +12V rail PSU's on the market, especially if they're "modern" or Crossfire or SLI certified.

And the Seasonic built Antecs don't even have multiple +12V rails. The label says they do, but they don't. They're single.

No offense (I'm saying this because what I'm going to say is going to sound harsh but I don't know any other way to phrase it) but if you're perpetuating the myth that everyone HAS TO HAVE single +12V rail PSU's and don't even know if the PSU you're suggesting against is actually single or multiple +12V rail in the first place (something that's been disclosed by a number of review sites that took the unit apart and failed to find any OCP sub-circuitry), then maybe you shouldn't be offering suggestions in the first place??? Sorry???

The Corsair is a better over all quality than the Antec, but the Seasonic built Antecs (NeoHE, Trio, EarthWatts) is still a very good power supply. If the Antec is in your budget and finding the extra dough to buy a Corsair is like trying to get blood from a stone, I can't find any legit reason to disuade you from the Antec.

You actually don't need to spend that much to get a decent PSU for your computer.... but it is good nonetheless.
