Is the NVIDIA GTX 1050 compatible with my PC?

Hello,

and welcome to CCM ;)

I find several configurations for the Acer Aspire MC605, with an i5 or with an i7. Is that your PC below?

If yes, you should be able to install a GTX 1050 instead of the GT620; in principle, the motherboard with an 1155 socket (so from 2012) should accept it, as branded PCs are often finicky:
the ideal would be to test it in a specialized shop!

Also pay attention to the width:
the GTX 1050s are dual slots (double thickness):

If your budget goes up to €150, you have the GTX 1050 Ti:

The 200W power supply is really tight!
Even though the GTX 1050 consumes little (about 60W max), it would be good if you could change the power supply too ;)

Basically, it means that the GTX 1050 is not compatible with my PC?

Sure, thank you!

If it doesn't work, could you recommend me some graphics cards that have the same power as the GTX 1050 and are compatible with my PC?

Sure, okay

I found 2 graphics cards that interest me. They are the GTX 650 and the GTX 750, are they good? And are they compatible with my PC?

I would like to play games like Planetside 2 and ASC3 with good FPS.

Who has a website where I can buy the GTX 1050 and return it for a refund if it doesn’t work?

Hello,

all sites accept returns within 14 days, it's the law!

for example:

you can read the return/cancellation conditions at the bottom:

The Nvidia GTX 650 MSI costs 100 euros and the Nvidia 1050 Ti MSI costs 189 euros
Personally, for Christmas, I'm getting the 1050 Ti for 189 euros with double the performance

But the 650 is very good because it consumes almost nothing, but personally I play in HD 1080, so its RAM a bit I need more power X)
