I am not sure what to do. I've got this PSU in my Pc an FSP with a max of 336 WATT. I also have a AMD APU A10-7800 processor in it. I want to add a RAdeon HD 6850 to it and change the APU cable from my psu to it.

The question is. Will my PSU and motherboard survive this adventure?

Thank you.

Is that 336W(28A) just on the 12v rail or total wattage ? Any idea what the specific model is ?

If it's 336W/28A on the 12v rail it may work, but you'd be cutting it very close.

It's an FSP350-40EMDN. Those other things I'm not sure of. But if you want I could send a picture of the specific information.

That would help, but only if it states what the combined 12v rail output is. Also bare in mind that age can effect PSU's output with capacitor ageing, so if it's a good many years old it's best replacing it anyway.

Note, the 6850's do need a supplemenatry 6 pin power connector, so if you don't have one, you'd need to check if the PSU has 2x molex connectors for a dual molex to 6 pin adapter.

Bottom line, if you don't want to replace the PSU, get a GTX 750 (60W). Or upgrade to a 450W PSU to be sure e.g Antec VP-450 or Corsair CX 430W.

The PSU is like never used before and bought 1 month ago with the computer or less than a month. And how do I add pictures here?
About the 6 pin. I think there is already one that's connected to the motherboard. Do I just use that one for my GPU then?

FSP are a good manufacturer, so i doubt anything catastrophic would happen if they're wasn't enough power. Your welcome to try it, but at your own risk.

No, if the PSU doesn't have a PCI-E 6 pin (designed for graphics card) wired in into it like this:

Then you'd have to rely on a dual molex to 6pin adapter (the card should come with one) like this:

In which case your PSU needs to have two molex connectors available to plug into it, that look like this:

I think it has the PCI-E thing right now but it might be plugged into the APU processor could that be possible ?
And also maybe it could be useful to send you a picture of it?Just to be sure of it?

DON'T UNPLUG THAT

What your describing sounds like the 12v 8/4 pin CPU power plug that goes into the motherboard near the CPU socket to power the CPU. It's there to power the processor & the APU (intergrated graphics) built into the processor, so it powers both. If you unplug that your CPU wont work.

If you have the cables i described & pictured above you can try using the 6850. If not, get a new PSU.

Yeah but there is one at the VGA output of the motherboard and one next to the CPU.
