Is this backwards compatible with PCI-Express 2.0 slots?

PCI-E 3.0 cards will work in a 2.0 slot, but it will not be able to run at full speed.

I didn't try, should be. Don't recommend this seller. My card works, but have some kind of problem that doesn't allow it to run a full speed. I have to manually downclock to make it work propertly.

Yes, all PCI x slots are compatible with one another. The slot ultimately controls the speed though, so it won't perform as quickly as it could. But honestly, you won't be able to tell the difference. Also, the other commenter may have just had a bad experience. This card is fantastic and I've never had a single issue.

This card is backwards compatible with any pci express x16. So yes it should run fine, but make sure your hardware is not gonna limit the full potential of the card.

Not as far as I know. can use Pcie 1, 2 or 3. Might see performance issues if only 1.0

Yes, it is compatible. Your motherboard supports PCI-E 3.0 and it is backward compatible with 2.0.

Well, according to Tom's Hardware user forum, yes it is: http://www.tomshardware.com/forum/382646-33-pcie-backward-compatible. For the second question, I would suggest you go to the EVGA website and look up the specifics... I put a Corsair 650w in my computer a long time ago, and haven't worried about it too much - thought with all the HD's I've put in recently, I may want to switch to an 850w. Antec and Sesonic make good power supplies also.

Works in the PCI Express 2.0 slot in my HP Pavilion's motherboard. Yes, it is backwards compatible

Yes, PCI-E 2.0 is backward compatible to PCI-E 1.0; however, you will not get full performance from it. With the price point on this the way it is, you reduction in performance is probably not a big deal. I would caution against using modern video cards with older power supplies. Generally, for modern graphics cards a 500W p/s is a minimum starting point--I would not go under 400W.

hello this is what I understandIf the module M.2 PCI Express is installed, the PCIE slot is disableddo not know if it's true I have not proven

Yes. The PCIe 3.0 spec is backwards compatible, however there may be some minimal performance loss over a Gen 3 slot.

Absolutely no problem. However you do need to make sure that you have a motherboard that has this kind of pci-express slot/support though and if so your good to go just find out from the manufacturer if it does and if not then you know to ask what kind of card slot it does have and order one for that slot. I hope this helps you.

yes all PCIe technology is forward and backward compatible to the least common denominator if you put a 3.0 card in a 2.0 slot ir will run as 2.0if you put a 2.0 card in a 2.0 slot ir will run as 2.0if you put a 3.0 card in a 3.0 slot ir will run as 2.0if you put a 3.0 card in a 3.0 slot ir will run as 3.0same true with 2.1, 1.0, and 1.1 cards

Dirk, when I purchased the board last year I may not have acknowledged its PCIe 3.0 expansion slots; but according to ASUS, all 6 slots are PCIe 3.0. Sorry if I provided misinformation, hope it didn't hinder or delay your build.

Yes,with the caveat that you make sure bus (PCI,Ph I Express) matches the card. I am surprised that your computer is running Vista tolerablywith so little RAM,but congratulations.

Only requires PCI-Express 2.0 x1 Slot. But it is compatible with all others. You will NOT see any real speed boost from using a faster slot.

I would &#8730; the XFX manuf. site , but see no reason why not; most cards and modern devices go backwards compatible one step or more ...however, why would one be even using such an older slot? This card would be like a hammer for killing flies on an old mobo, if everything else could even keep up (which I doubt). What are you thinking of using this with/as?

Yes it is compatible. If you would like to know more about the differences, here's a link - http://www.trentonsystems.com/applications/pci-express-interface
