I know i need to upgrade PSU as my current one is not powerful enough but how many watts psu would i need to if i were to put this GFX card?
And MOBO is Acer AAHD3-VC
Thank you!
 
Solution
Get a 500W power supply of a good brand like Seasonic,Coolermaster or Corsair

Okay thank you very much and also will my mother board support the gfx card i want to get?
I read somewhere that pre built pc motherboards can only support the components they came with...
Mobo model: Acer AAHD3-VC
it has pci x16 2.0
 
For a system using a single Radeon R7 250 graphics card AMD specifies a minimum of a 400 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 20 Amps or greater.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most critical factor.

What is the brand and model number of the 300W PSU? There are some 300W PSUs that wouldn't have any problem powering a system with a Radeon R7 250.
 


Well that Graphics card requires 2 pci x16 3.0 slots (as seen in the link you provided),,,so it would be better if you change the mobo as well.
 

But its still compatible right?
PCI 3.0 is backwards compatible from what i have read
 


Thank you but upgrading mobo is not a option but it says it works with pci 2.0 so it will work with my current mobo.
 


Well then! my mistake,,,anyways glad to help you out :)
 

Okay but the current PSU is only 300 and its from a pre built :/

 


It okay haha
Now to find out this gfx card will fit in my case haha

 


Cross your fingers :)
Best of luck man! Happy Gaming
 


Acer used the FSP Group 300W (FSP300-60THA) PSU and they would be inadequate.
