Is this a good psu for asus sli?

[nitro28]

Is this a good psu for an asus sli with 2 bfg 6800gt's. I am trying to stay at about $100 for the psu. Also do I have to buy a psu with pci-e connectors?

Why on God's green earth you would need 560watts, I don't know, but yes, I have a similiar model with lower wattage. They seem to work perfectly, and are fairly quiet.

You could definately do better.
22amps on the +12V is really low for a 580 watt power supply.

If you're going to spend $100 you're probably much better off getting an Antec, OCZ, or Enermax.

 

[nitro28]

what amp rating should I look for?

 

[slpaulson]

I would consider this power supply.

It has a total of 33amps on the 12V line.
For running an SLI setup I'd want around 30amps.

I'd also consider this.

A good PSU can last you through one (two if your lucky) upgrades, so why not go for a big dog, that way in the future when we're all running double, dual core cpus, and three vid cards (*wallet yells "please nooo!!!"*) nitro will still be livin' large on his 560! :laugh:

You might to consider looking at power supplies from Antec, Enermax, or UltraProducts. The thermaltake you are looking at has only 22A on the +12v rail which is very important for power hungry Nforce 4 Sli boards. All the manufactures listed above offer power supplies for about the same price with better +12V ratings. If i had to recommend one I would say the Antec True550 is a great choice for $100. It has 30A on the +12V rail. Newegg lists it as 24A on the +12V, it's a typo, check here. (Also, I own one)

Excellent point joelslaw. I bow to your wisdom and forsight...:roll:

 

[joelslaw]

The latest ultras havent been fairing so well, I'd go with one of the others.

Check the fortron blue storm 500 watt. Stronger on the 12v(where the SLI cards will draw).

100 bux if I recall correctly.

[MisterChief]

Thank you very much!

 

[nitro28]

the fortron blue 500 watt says its 15amps on each rail right, isn't that lower than you guys just said?

 

[nitro28]

here is the forton forton blue

it is a version 2 so it has pci-e plugs but is 15 amps seem low?

It has two 15amp rails.
So there's a total of 30amps.

It's probably 15 for the cpu, and 15 for the rest.

So the fortron blue should be pretty good for $100 and it has pci-e plugs and nice sheaths.
