Should i buy GTX 750 Ti with my 290W psu?

I an planning to buy GTX 750 Ti for my Dell Optiplex 3020MT. However there are 3 things i'm worrying:
1. Minimum PSU for GTX 750 Ti is 300W but mine has only 290W. And its +12V too. I never bought a GPU before so i won't sure if this PSU can handle it. Here is it: http://i.imgur.com/CInuQzB.jpg
2. Will my mobo fit it? Here is the mobo: http://i.imgur.com/1W0ghzO.jpg
3. Can it play Hitman (2015)?

GTX 750 Ti would do fine on that; however that is the max it could go.

Make sure it does not require any extra PCI-E power connectors (like the one below) as you won't be able to have access to those with those Dell Power Supplies.

GTX 750 Ti is 60W card despite some vendors slapping 450W PSU recommendations on it to cover their behind for all kind of configurations.
If you get non-overclocked card that doesnt need extra power cables then it should be fine.
Cant really swap the power supply anyway with this motherboard, modern ATX power supplies have 20+4 pin or 24 pin main motherboard connector that your motherboard doesnt have.

Ok but about the +12V, is it compatible?

Your motherboard has the PCI-E slot, all you need to do is pop the card in there and done, it takes all the power from motherboard slot.

Oh ok thanks

U can't

That Dell takes a certain kind; and it's not ATX

You can see this in OP's linked picture for motherboard.
Notice the green and white 8-pin; that is the main power. Then on top of that the SATA power is coming off the board via another special connector.

You are right. The PSU use a different kind of connector (and so does the mobo).

A PCI-E slot is supposed to provide 75 watts and the GTX 750 Ti only uses 60 watts max (hardware limited by a regulator). If any of them have an external power connector it may only be to give it insignificantly more power for fan(s).

The only other thing that might trip you up is some newer cards expecting your PC to do UEFI (which Win8 uses). I heard of someone with EVGA GTX 750 Ti that was not compatible with their BIOS. I have a 5 year old PC without UEFI, but my MSI GTX 750 Ti has a dip switch for hybrid UEFI/BIOS or regular old BIOS and I have not even tried the hybrid UEFI/BIOS setting to see if that works, I just leave it on the BIOS setting.

My Dell XPS 8100 (from 2010) with i5 650 3.2 GHz, 8 GB RAM, and MSI Twin Frozr Gaming GTX 750 Ti OC only uses 150 watts max AC input (Kill A Watt meter) when doing graphic benchmarks even if I overclock it even more (due to the card limiting itself to 60 watt). HP has been know to overrate PSU's (I had one from 2004 that could not handle half of its watt rating), but Dell seems to have conservatively rated PSU's, so I do not think that power should be a problem for a GTX 750 Ti. Older slower cards used as much or more power than this new efficient one (my GTX 550 Ti used almost twice as much power, 116w vs. 60w).

i dont see any choke coils around the cpu, must be a very low power cpu
and only 3 near the 8pin main power plug (with green remote on)

the boards onboard regulated power draw is around 60-75w (assume 20-25w per choke)

the 290w psu will be more than enough for that

My processor is i5-4570 with TDP around 84
