UD-9 PSU

[alainneedle1]

Hi! is there an certified PSU for the UD-9?  If not what will be the best one for it (3 GTX 480).

Thank you.

Certified here for SLi

Antec TPQ-1200 1200W  is the cheapest I would recommend.
Another that is not listed is:
Cooler master Silent Pro Gold Series 1200W

Thank you, I'm looking for a PSU with two 8-pin CPU power headers and 3 card SLI......look here

Its ok you don't need two and really it shouldn’t need two one 8 pin for one CPU is enough but heres what the manual says.
“Use of a power supply providing a 2x4 12V power connector is recommended by the CPU manufacturer when using an Intel Extreme Edition CPU (130W).”

Both Antec TPQ-1200 1200W & Cooler master Silent Pro Gold Series 1200W have 2x 8pin any way and many other will likely have too.

I know I don't realy need to 8 pin for the CPU but I will try to overclock my 980x as much as I can (4.5GHz with the NH-D14) so I want to be sure I have enough power to be as stable as possible.....

There is the Silverstone Strider 1500W or the Thermaltake Toughpower 1500W. Both are more than ample to run the UD9 and will run at their optimum power output for efficiency for what you intend to use them for.

Thermaltake does not have the 1500W   http://www.thermaltakeusa.com/Category.aspx?C=1245  they have a 1350W maybe that's good enough....

Newegg does not have it either   http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007657%2050001379%20600014027&IsNodeId=1&name=1101W%20-%201500W

Do you know where I can find the Thermaltake 1500W?

Thank you.

EDIT: Is the Silverstone a good brand? Any reviews on it?

I take it that if you can't buy the Thermaltake 1500W then you are in the USofA? Can you update your profile to show your location please as this is the type of problem we get when we don't know where someone is.

Sorry about that...here is the new profile.

Yes that's what I thought. For some reason it is not allowed to be sold in the States because it is too powerful. First time for everything I suppose Shame because it would have suited you perfectly. The 1350 would probably be your next best.

Toughpower Cable Management
Proper airflow within computer system plays an extremely important role in making sure CPU, Graphic Card(s), Hard Drives and other critical components are getting adequate cooling. Thermaltake Cable Management Technology allows users to only use the cables needed from the power supply that reduces amount of cable clutter within the computer to improve cooling and reduce system noise.

I have just been doing a little more checking and Corsair have a new model that would probably suit you, it's the AX1200 model and comes with a 7 year warranty. The Corsair range is excellent and I run a HX850 myself. They have the added bonus of a single 12v rail which is more stable and can supply huge starting current.

The Silverstone is also good but I haven't had any personal experience with it. I think that you might need an adapter  for the third 480 8 pin though as I think it only comes with 2 and four 6 pin.

You don't need 1500W a 1200W PSU is more then enough for 3 GTX 480 and a 980X with a half a dozen HDD/SSD.

The only reason you can't use you ABS 1300W is it don't have enough connectors on it.

It is not just a case of the minimum rating that you can get away with though. It is also about the fact that PSUs run at their most efficient at around 50 - 60% of capacity so it pays to have a larger output model than you physically require.

This is no longer a big problem any more with 80Plus Gold PSU giving 86%+ Efficiency at 115V/60Hz on a 100% load.

I know the theory but if you look at the graphs you will still see that they are more efficient at a lower output even though they maintain a high degree of efficiency up until nearly full power.

[Peteruk]

You don't need more then 1200W for that setup more efficiency with more watts is pointless for a little more efficiency at high load because at idle, browsing or working the CPU at 100% without the GPU's running up the efficiency drops the other way when the GPU's are idle so theirs really no point in getting a more powerful PSU.
