Hello MattSid, Are you advising that each card requires a 400 watt power supply? If so, you would be talking 800 watts in a system designed for 180 watts.

If you managed to install two of these in this case, you most likely would not have the available power connectors for the higher performing cards.

I almost have my doubts that just one of these cards would work in the system even if you could manage to upgrade the power supply. The 180 watt power supply would be very small, and a 400 or 800 watt power supply would just be too large to fit in the case.

I just checked the specifictions for your system and it does not have even on PCIe x16 video card slot.

Here  is the link for the specifications for your system.

If you need a higher performing system, I would suggest purchasing a new system that meets your requirements.

No, i will only be fitting one card so only 400 watts. And would i be able to install a 400 watt power supply to replace my last power supply?

Hello MattSid, Take a look at the specifications for the motherboard in your system.

Here  is a link that shows the motherboard. It does not have a PCIe x16 video slot.

It does show 2 PCIe x1 slots to be used for additional hardware devices, but not video cards.

Hans,

I found a reference to what is being asked. It is a PCIEx1 garphics card, requiring 400W PSU.

That said, he is going to need to get the model # off the old PSU, and measure it. It's not easy to find cross-references.

Hello wb2001, Thanks for that information and link. That appears to be a nice card, and the reviews were very good.

I looked at the specifications for the model he listed and it shows the motherboard does not even have a PCIe x16 video slot.

He may have given me the wrong Model number, or I may have looked upo the wrong Model number.

But the one I looked up has only two PCIe x1 slots. But you know how blind I am.....

Hi,

It appears that the H-Aira-RS780L-uATX (Aira-GL8) motherboard in your PC has been functionally stripped. A couple of memory dimm slots and the PCI-E x16 slot have been removed.  Even if you could find and get a PCI-E 1x video card to work it most likely would be a poor performer.
