Perhaps I can add some important information to this discussion.
A quick search shows that your CPU is one originally built for laptops! It does have integrated graphics, so as someone mentioned earlier, make certain whatever cable you are running to your display is plugged into the video card, not the VGA or DVI output from your motherboard - those will be located with all the other I/O at the top back of the case.
Also, re. power. The recommended power supply for a COMPUTER running the 1050 card is 300watts: However, that is not how much power your 1050 will ever draw. Your video card is rated at 75W. IF your card has the auxiliary power connection mentioned by Flaming then that does need to be plugged in and your PSU probably doesn't have a proper connector to use. HOWEVER there is the possibility that your card is a standard 1050 and will not have such auxiliary connection.
And a final thought: Your processor is rated as using a maximum of
15 watts! If you have a 240watt psu you are probably o.k. without replacing the PSU .
ALL OF THE ABOVE makes the assumption that your PSU is in excellent condition as well as all the other parts of the PC.
Below are links to your processor information and to Tom's Video hierarchy chart.

UPDATE: Just looked at the Dell Service Manual for the 3656. That PC has a proprietary PSU and proprietary motherboard !! You cannot use generic, off-the-shelf parts to repair or upgrade. Your PSU will NOT have an auxiliary power connector for the video card. Here's the link for the manual:

You might be better off going back to your R9 360 or look for one of these: evga 1050 SC or any brand 1050 that doesn't require the extra power.
