Compatibility Question


Jun 6, 2012
Hello everyone, I'm looking to buy a new PSU & Videocard, but after searching I can't find several key deatails I need to know

How do I know what kind of PCI-e slot I have? I know it's a PCi-express but i can't tell if its x1 x16 2.0x16 2.1x16 ect.

second I can't find information letting me know if the PSU would be compatible

"Acer inc. IPISB-VR" is the text on the motherboard <-- that's my tower, it's the cheapest model

can somebody help me out here
I can't imagine that there is a current motherboard that does not have at least one pcie-x16 graphics slot.

So I did some research, and it will support a high end discrete graphics card.

Pcie 1/2/3 etc is irrelevant, they are forward and backward compatible. And... no card sold today will be impacted much by running on a slower interface anyway.

Your 300w psu should be good enough to run a card as strong as a 7750 that is powered entirely by the pcie slot.
Possibly, the new GTX640 will be ok.

Otherwise, you are looking at a psu upgrade also.
If you are looking at a really strong card, or an older one, check the length of the card, and how much space you have in your case for it. Some can be 11" long.


Given that the system is running a Core I3 2120 processor, I would expect it to have a PCI-Ex16 2.0 (or 2.1) slot. This means it could accept any PCI-Ex16 graphics card, as there are no compatibility issues with this version of PCI Express.

The system has a 300W power supply, and I would expect you could swap that out, easily enough with a better power supply.
