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

There is no need whatsoever to change the motherboard.

There's no need to get a 500W PSU either.

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