yeah, from what ive read i hope its theyre last one left.....
I looked into this. My old man is an electrician. Dual Rails are instantly in-efficient compared to Single Rails. Due to the fact of standard electrics.
If you output two splits from the same supply there is DOUBLE the resistance. Thus obviously proving that Dual Rails can't supply the combined amounts of rail A + rail B. Standard electrics an Intel overlook it. When really it's blatantly obvious.

That jonnyguru guy is making false statements.
Just me quote something he states:
One can NOT make a powersupply that has no ripple.
All PSU's high-end or low-end have a ripple.
It can be very low, but it will be there.
And the statement build like a server PSU but with home user in mind is balony too, server PSU's are build to fit a SPECIFIC case, like 1U, 2U or bigger.
They totaly differ from home systems, as server systems do NOT care about the noise they produce.
However, his tests are better then most, not good enough, but better.
As he fails to put the load up that high that all the lines are being loaded upto their max.
He doesn't check when the PSU is going to shutdown.
Other then that, he's better at it then most others.

Stu, I have a problem with them as they use:
http://www.pcpro.co.uk/custompc/labs/42/high-end-psus/products.html
Sorry, but they just blew it in my opinion.
No way that can be a fair test. I don't trust them anymore.
Then look at what are premium PSU's, just guess.....right Enermax....

It's not blatantly obvious that outputting two splits from the same supply doubles the resistance. Probably because it's not true.AaronYuri said:
The main problem with split-rail PSU's is, as stated above, that it's inflexible and one rail can be overloaded while another is underused.
I believe the reason PC-Power ever went for multirail is cuz untill reasently they couldn't make a single rail strong enough cuz of the 240VA limit, but then I'm no expert so I'm only guessing. But in the end, the importent thing is, they DID drop the multirail crap and now they make the most stable, reliable and unkompromised PSU's in the world, Period....
That sayd, I'd like to recomend what I find to be the best PSU's on the market today, I'd say their 1kW beast if it wasn't for the price cuz 500$ is way to much for a PSU unless you want Quad 8800GTX/Ultra and Quad core CPU or more, then you have no choice
... I just got my new rig up and running smooth now on their Fairly new Silencer750 Quad (Copper), bought it directly from PC-P for 199$ plus shipping to sweden which is just a little more then I'd have to pay for say Antec's flagship, but then the dollar was verry low at the time making it alot cheaper for me.
I had an old PC-Power TorboCool 510 Deluxe without the PCI-X 12V connectors and only 20pin ATX but still 34amps on the 12V rail (Sinlge) and it seemed it couldn't quite power my new 8800GTS card under heavy load, atleast I think that was the problem cuz it kept crashing occationally in some games and windows reported a problem with the grafix driver after reboot.
Now enough of that old problem, the new Silencer750 Quad is working just fine, it's stable and not to mention VERRY Silent, it's Sertified by nVidia to handle two 8800GTX in SLI mode on it's impressive 60amps SINGLE 12V rail and I'd take their word for it, and the price isn't really that high either if your goin for a 8800 SLI/2900 X-Fire config in which case ~35amps wont be enough if you want it stable.

Hope some1 find this usefull when choosing their next PSU

especially when you have the parts like 2x8800 in a system.
Earlier, I stated some things about Q-Tec ...
Well, have a look here, it's a great laugh. Bosskiller found it ...

Or are there people out there looking for a psu-driver? ???

Pumping up the +12 amps and at decent prices. The 450 would be good one for me. Further proof that watt ratings don't mean a thing except advertising hype and leading people into buying inferior PSU's. $25-$50 450W PSU's = +12V~16-18 amp, simple fact more money, more amps and better quality (most of the time).
