1200 W enough for you?
Components are a big part of Computex, which is really just heaven for those who build their own computers. Enermax was there to display its newest power supply units, which all reach the 80 Plus Platinum mark as part of the company's Platimax line.
These PSUs reach an efficiency at half load up to 92 percent. The Platimax will be available in 600, 750, 900 and 1200 watts configurations, with the most powerful model having completely modular cable design.
No pricing yet, but we're told that the high-end models will be available in July, while in more modest versions will follow in subsequent months.

Knowing Enermax's track record quite well, this will probably be yet another absolutely kick ass PSU, albeit very expensive. Technology progresses so quickly. Back when I purchased the Modu87+ I'm currently using, it was pretty much the most efficient PSU on the market, and certainly one of the best designed. And now only about a year later we have 80+ Platinum PSU's coming to market.
do want... if under 150 for the 600/750 model
Knowing Enermax's track record quite well, this will probably be yet another absolutely kick ass PSU, albeit very expensive.
I have a 460w Enermax PSU I bought in 2004 that is still running great. It's outlived all the other components from two different builds. I don't think Enermax prices are that much more than other high-quality brands, but I have seen enough problems caused by bad PSUs that I wouldn't buy anything less.
I'd like to get my hands on a 750-850W version... 1200 is a bit overkill for me! lol
Does 1200watt support tri-SLI 580s or is that enough juice?
Tri SLI 580's puull about 55 amps peaking to about 70 amps, so a 1200 watt PSU will provide more than enough power.
Aren't most household circuits only 15amps? 55-70amps are definitely going to trip a few circuits...
Plus Enermax sometimes under-rates their power supplies (compared to a lot of vendors. If you look at the amp ratings of some of their better 600-650 watt designs they read like a common 900-1000 watt unit.
My first separate PSU I ever bought, for a build back in '01, was a dual Fan 430 Watt Enermax that I powered a Dual XP2000 system with. It was kicking just fine up to the day I stopped using it and sold it in '08. Far as I know it still works. Currently using a 600W Pro87+. Cost of an Enermax is always justified when it's tasked to power components that are each still more expensive than the PSU itself.

Yes they are.
15 Amps of 110Volts AC Supplies up to 1650 Watts (Wall Current).
55 Amps of 12 Volts DC is just 660 Watts (PSU Current).
A system powered by a 1200 Watt PSU won't regularly demand near its rated max most of the time. The Computer and a few LCD monitors should be safe on a single 15 Amp breaker, even while gaming. I admit even I cross my fingers when I send something to my Laser Printer, though. It makes the lights flicker a tad. Hope that clears that up.

i've been using my hx750 for two years, and it reaches 90% efficiency at 50% loads according to the official website

That's why power supplies have those large transformers inside-to step down the voltage and step up the current.
Other than the ridiculous name, the PSU's look good, except it looks as though they may use the same ugly fans that grace the Gold Enermax PSUs. Every review I've read has the testers complaining about the awful, cheesy looking fans..

Not at 12V DC, which is all internal to the computer, the two are seperate. 1200W/120V = 10Amps + whatever the loss is (remember, not 100% efficient)
Huh, no sleeving?
Good PSUs and an interesting point is the 92 percent efficiency when the unit is at half load.
