Alienware x51 R2 Upgrade to GTX 1070?

[calmmade]

Hello guys,
Im looking forward to upgrade my Computer, especially the GPU.
I got the Alienware x51 R2 with those specs:

Windows® 10, 64Bit, German


4th Generation Intel® Core™ i5-4460 Processor (6MB Cache, up to 3.4GHz)

NVIDIA® GeForce® GTX 745 with 4GB DDR3

8GB Dual Channel DDR3 at 1600Mhz
-> Upgraded to 16GB Dual CHannel DDR3 at 1600Mhz

1TB SATA 6Gb/s (7,200RPM) 64MB Cache
-> Upgraded to a Samsung 850 EVO 500gb SSD (replaced the hdd)

and my question was if its possible to upgrade my pc with the upcoming gtx 1070 because im a bit afraid because of my PSU and stuff like that, thanks for your help

sincerely calm

If you have 330w PSU, it will work.
If you have 240w (standard), it will not work and your best bet is RX460 or RX470 (or any if and when upcoming GTX 1060/1050) card with ~100w TDP.

The PSU (black block with cord between your computer and the wall socket ) should have a label that describes the input (110-240v and amperes) and output in either watts or voltages and amperes. The later would be something like Output 19.5V - 16A
