Which PSU to choose??

Post your entire configuration so we can see what we are working with. Are they compatible well that is why there is a specfication after all ;)

Now do they play nice? Well the Blue Storm does but I don't know about the ePower off the top of my head.....but ti should. Might want to look over at DFI street.
 
The TG-480 is a great little power supply if you don't want something with dual 12V rail (for whatever reason that may be.)
 
Here is my setup going to be:

AMD 64 3000 VENICE
LEADTEK 6600 GT PCI EXPRESS GDDR3
DFI SLI DR
PQI TURBO 512 MB RAM DUAL CHANNEL.

Hardrives? Optical drives? Fan's? Cooling?

Hey guys. I am having a difficult time for which PSU to choose:

ePOWER Tagan TG-480 ATX 480W Power Supply http://www.newegg.com/Product/Product.asp?Item=N82E16817101509

or

FSP Group (Fortron Source) AX500-A ATX12V 500W Power Supply http://www.newegg.com/Product/Product.asp?item=N82E16817104934

thanks for ur help. also r both of these PSU compatible with the DFI SLI DR??

Either is fine for non-SLI, neither has enough for highend SLI.

YourCPU isn't going ask for more than 89W and the 6600 isn't going to need more than 80W on the 12V rail. That's only 14A or 21A if you're going to run those 6600's in SLI. Give yourself another 8 to 10A for other cards, drives, fans, etc. and you're at 30A or so. Now mind you, that's going to be a max load, which is also very unlikely (all your drives will be spinning up and both of your video cards and CPU under full strain all at the same time.) but it's still good to have that "buffer" in there.

The ePower is cutting close. One 6600GT? No problem. Two? I don't think so much.

My problem with using the FSP is the balance of the two rails. That and the max capability of the two rails combined is only 21A. That's not much.

FSP should have at least used voltage regulators for the 12V rails that could do 18A each. But then there's still the problem of the max capability of both rails combined. You really should look at a dual rail PSU with at least a combined 12V rail capability of 372W or better (31A and up. And you DO NOT get that by adding 12V1 and 12V2!)

Dave's suggestion is based on DFI recommendation. Since you're planning on using a DFI board, you may want to follow those to a tee. Sure, they're overkill (IMHO), but DFI will totally ignore any support requests you may have if you don't use every single component they suggest. Essentially, you'll have an expensive PC where the only cheap component is the motherboard... but at least it should work flawlessly and you can get support if you need it. :D

Do you have newer data that I don't have? :confused:

We were able to get about +12V@26A combined from the Fortron Blue Storm 500W awhile back.

Thanks,
Dave
 
I'm sorry. I meant to type 24A, not 21A.

Still not as much as it should be to be considered for any kind of "power rig."

I'm sure you did have one up to 26A. But they have to pull that off for at least an hour before the PSU company can make that claim.

I actually had the 13A rated 12V1 of that Silverstone up to 22A last night when I was playing with it for you. Never even hiccuped. I wanted to see where they had the overload set. It's set to 22A, BTW. Over 22A the PSU cut off.

What's funny is the documentation says that it's set to 20A which is what Intel suggests the automatic overload protection be set at in order to meet Intel ATX12V2.2 specs.

But yeah.. I miss typed. 24A is the max combined 12V rail.
