Which one do you think looks the best, and which do you think performs better?

Are there models in this list you would not recommend, and why is that?

The question is your thoughts on looks better and also what you think in just terms of what you think has better performance. :bounce:

"Looks" are the last criterion I have for a PSU. Of those you have listed, I have no doubt that the PC Power and Cooling model is good for every milliamp of its claimed ratings. I'd also trust the Silverstone and OCZ.

Agreed!

Why in the world do you need a 1200watt PSU?

Even sli/crossfire of the most power humgry cards don't need more that the PC P&C silencer 750.

Well I am currently running (2) Radeon 4780 X2 in crossfire,


Also powering (12) 12cm case fans, (3) VelcoRaptors will be 4 shortly (running in RAID 5; soon RAID10), also have 7" LCD display from Thermaltake


Also running power from the PSU that has a SATA Power connection. I have the Thermaltake Mozart case.


I am currently running a ToughPower 1200W, and wanted your opinions about these PSUs. I am running TT V1 cooler atm, but when Thermaltake comes out with the Freon Cooler, I am going to jump on it, and that operates at 60Watts. I also have a LCD display of both my PSU ussage and fan control, and I am utilizing 78% on idle, and upto 82% on full load of the power supply.

My ddr3 choice I got was Patriot Viper DDR3 1600 (PC3 12800) (2) 2GB


And cooler for the RAM "OCZ XTC Cooler"

i love my Silverstone 1200watt. I've never had any problems out of it, and it's an 80% unit good for up to 1000watt output.

Jesus that's one hell of a rig. What do you do with it? That's what I'm dying to know!

You are using 78% of the PSU's capacity on idle? That's scary...

Of those listed, I'd pick the Turbo-Cool. Expensive, but worth it for a rig like yours.

Edit: Just curious: what motherboard did you get, and are you using a RAID card or the onboard RAID?

I always vote for the PCPower and cooling PSU.
That's one hell of a load you have on your system, I hope you live in one of the places where the electricity is cheap.

Toughpower 1200W Power Supply is what I run and it's nearly silent with excellent reviews. It exceeds the efficiency rating according to independent testers. I don't even think many of the others were out when looking.

+1 for PC Power & Cooling. Damn... 78% idle?
September 11, 2008 5:13:07 AM

When Thermaltake comes out with the 2000W PSU I am probably going to consider buying it. I still have thoughts 1200W of power even at 87% efficiency will not be enough power for future upgrades that I have in plan. I don't care if my electricity bill goes up more, not that important to me.



When I do go for freon I am thinking I will also put these on my 2 Radeon 4870 X2 for cooling.
