Nvidia 8800GT OC on a Akasa 400W PSU?

[Teh GaZa]

Hi guys my friend wants to add an BFG 8800GT to his system which currently has an Akasa 400W.

I am confused on which cable to use to power the card, the 6 pin or use two different molex connectors to 6 pin. As I am not sure the 6 pin will have enough wattage?

Thank You

Either or, it doesn't matter. But I would use the 6pin connecter marked with pci-e.

OK thank you and do you think it will enough power.

The specs are:

Core i3 2120
4GB RAM
Nvidia 8800GT 512mb

Thanks again

Should be enough, so long as you're not running alot of add-ons, sli, raid array, enough fans that your case sounds like a helicopter, lights, etc.

No its a basic PC with 1 PCi-e x1 card and thats about it

It'll be fine then.

I've just noticed that the 8800GT needs 26A on the 12v rail but the PSU has one 15A rail and 14A rail so will it work.

Thanks again

That will not be enough if one rail is used, if you used a Molex to 6 pin PCI-E adapter with both those rails dedicated to the GPU, then it would work. That means you cannot have anything else connected to those rails, the only exceptions are a fan or 2 at most.

Sorry, didn't notice that about the 26A.

Ah even worse all the molex cables, 6 pin and 8 pin are on rail 1 14A and only the CPU 4 pin cables are on Rail 2 15A.

So even using 2 molex to 6 pin would not work :/

But I seen last night someone said that 26A is the full system requirements not just for the GPU itself. And with both rails it is 29A. I dont think a 8800GT will use 26A alone?

You're right, it doesn't.

Man, now I'm totally confused. After doing abit of searching and reading, I've come across it needing anything from 22A to 30A, and needing both a 6pin and 8pin power connection (images I've seen only seem to show 2x6pin connections and your description only suggest 1x6pin connection. Hopefully a power guru can jump in and clear this up.

if you have the psu then just run it and and see , else buy a new one

I may not be a power guru but I am still using an 8800GT and unlike some around here it is not even the first graphic card I have ever used. :lol:

The card has just standard 1x 6-pin plug, its not the GTX+ version. I'll plug it in and find out, Anyway thanks for the help guys.
