Power supply for my gaming pc?

[sahilchauhandd]

I'm using a Dell Optiplex with Intel i5-3470, 8GB DDR3 Ram, 500GB HDD and a DVD+/- RW Drive at a 250 W PSU. I wanted to add a GTX 1050 2GB for gaming. So what PSU should I upgrade to? When I checked at Cooler Master PSU Calculator it showed me my Load Wattage at 225 W (without the GPU). Please Help!!

This one for example will work:

I would recommend everything from this list:

You need to provide case size and model number for your Optiplex. But the truth is the GTX1050 2GB doesn't need a PSU upgrade. It can run off of the PCIe slot. Be sure and get one w/o the 6 pin PCIe cable.
77W CPU, and 75W GPU= 152W.
Basically Dell sizes their PSUs to safely and reliably power all the slots and bays and CPUs the computer comes with. On an office machine like the Optiplex this can result in a seemingly small rating. But it's actually a quality part, and unless you have the MT size case your options will be very limited.

It is Dell Optiplex 9010 - Small Form Factor (11.4 x 3.7 x 12.3) / (29.0 x 9.3 x 31.2).

The Dell PSU is as good as it gets for that, and since it requires a low profile GPU the 1050 series is what you want.
