Can this card run on my Dell Optiplex 745 SFF with a 275w Power Supply?

Yes it will. That is what I installed mine in but running a 300w power supply, which isnt to much of a difference in power. It runs off of the mobo, but it would not hurt to install a bigger power supply.

Yes, just need a sdram upgrade to eliminate tiling or pixelation with heavy software.

You will need to upgrade your power supply to have stable performance with this card. I recommend at least a 500 watt.

I installed this card on couple Dell OptiPlex 3020 SFF PCs without any issues. It's a decent card to support dual LCDs Panel w/Display Port.

I don't have experience with the Dell Optiplex 755. Manual for this PC has table of the compatible ram.

It depends on the other components in your system. I run a 450w power supply with this card and no issues. If your CPU is sucking up more than average watts you may require more , but this card has a very low power requirement considering pretty good performance.

can't be sure w/o your xpress code or svc tag - just look at the different form factors for optiplex 755 - http://www.dell.com/us/dfb/p/optiplex-755/pd that said - if your optiplex is no more than 2-3 years old - 99% yes, b/c it's PCI express ready and low profile (so should fit in small form factor - the worst case in sense of space for ext. card). given that - if I were you, unless you want to share your xpress code so I can actually check what hardware specs you have, then I'd say go for it - worst case return...

Should Work for normal usage, though I doubt the 460W PSU will provide enough juice for the card with intensive graphics use.

My Dells have a 200 watt power supply and have small video cards and they run fine.

This is a really great card. however, your concern is correct. I wouldn't try running it on a power supply that is less then 700w just to be safe. I currently run a 1100w Therm, and have had no problems.

The Dell Optiplex 755 has two expansion ports: one low profile PCI port and one low profile PCIe port. If you can find a low profile PCIe graphics card that will meet your requirements, it should work.

This EVGA GT 610 has a PCI-Express 2.0 x16 connector. If I remember correctly, your Optiplex 745 has one PCI-Express x16 slot, so this video card should work for you.NOTE: you can only hook up one DVI-D monitor (Dual link, which supports Dell's 30" monitor in the max resolution). The other DVI port can only go up to 1080P.

I have a Dell XPS 630i with a 750W PSU. I replaced my old card with my new EVGA GeForce GTX 780 Ti. It came with the cables needed, easy installment directions. It is much more quiet than my old card. Works like a charm.

Depends on what the total system requirement is. 750W is fine for most requirements, way more than needed for most requirements.

Yes the Optiplex 755 should have (check specs) a PCIE slot which this adapter would fit into.

The TDP of the card is advertised as 150W, although it should be a little lower considering it can still be overclocked within it's physical power input restrictions (75W through pci-E slot + 75W from the 6-pin connector). But yeah, 150W is a safe estimate. As to the wattage required to run a system (i.e. power supply requirement) people will throw random numbers at you like 500W PSU or better, but the truth is that it all depends on the hardware you are running. I suggest you do some google search for a power calculator and do your own math and see what kind of PSU you're going to need.

I had to bump up my power supply to a 750, it was a 450w, but you should have no issues. fyi, it consumes 4 power connectors, so you may need adapters if you dont have 4 available.

The instructions say that a 450W power supply is the minimum required. My power supply has 650W, so it's never been an issue.As for compatibility with the Dell motherboard, I would be quite surprised if that was an issue. It fits into a PCI slot, which seems pretty standard these days. It also requires supplementary power from a PCI-E connector, but an adaptor is included that allows you to get that power from standard MOLEX power connectors -- the kind used to power hard drives before SATA came along. By the way, I've been quite happy with this card!
