I want to buy a Radeon HD 6950 but I worry if my PSU is good enough. http://www.eclipsecomputers.com/product.aspx?code=PSE-9... this is it. Does it have enough amps on the 12V rail?
Thanks

That's a generic PSU I wouldn't even bother buying that kind of PSU.

Since that 6950 recommended PSU is at least 500watts

I think 900watts are overkill.

I prefer if you will post your specs in here to give you a better advice on what PSU you will be needed.

I already own the Storm 900w though. I know it is generic and not very good but I was wondering if it will have enough amps on the 12V rail for the HD 6950. I know it has enough wattage.

I doubt it will have enough amps, Since its an older model.

That's a generic overrated PSU ...

A 900 watt power supply with 1 PCIe power connector and about 45 amps on the 12 volt rails? What you have there is a 600 watt PSU for all practical purposes.

A 6950 needs about 15 amps at 12 volts and two PCIe power plugs. I think you only have 4 molex connectors and you would need to use two for a molex to PCIe power adapter.

So you have enough power capacity, but you do not have enough cables. And it is a low quality, obsolete design. I say "obsolete" becuase of the power capacity. It has relatively heavy 5 and 3.3 volt rails and relatively light 12 volt rails. Modern systems use 12 volts for all the high powered components (CPU and GPU). A good example is the 850 watt Corsair TX850. It has a 70 amp 12 volt rail.

If i buy the right adaptor cable ( http://www.amazon.co.uk/NEW-PCI-Express-Power-Adapter/d... ) then will the 6950 work fine? Regardless of the fact that the design of my PSU is 'obsolete'? I will upgrade my PSU eventually but I just want to know if for the time being, if I upgrade my graphics card to the HD 6950 will it be able to handle it without damaging my computer in any way.
