Will Radeon HD 7770 be fine with this motherboard/power supply?

I need to upgraded graphics for an animation software. According to the manufacturer AMD 7770 will work fine.

The motherboard in this computer is an AMD Athlon II X4 635 2.91Ghz DX10.1 with an integrated Radeon HD 4250.

Power Supply is a WT575i, total power 425w max output 575w.

Can I plug a dedicated Radeon HD 7770 into this configuration without the need to change anything? User may want double screens, and I'm not sure if the 7770 allows that, so if not, a like recommendation would be helpful. Also, will the dedicated card completely take over graphical duties, or will the integrated card fight it.

Thanks for any responses.

I would not recommend a 7770 with that power supply. The most i would recommend is a 7750. Which can also support dual monitors.

Let me rephrase that, the 7770 will most likely run off that PSU, you do have a 12v rail with 25 amps. But...after reading horrible reviews on that power supply i just would not recommend it. If you were to get it i would put in a Corsair CX 430 power supply.

Hi,

As far as PSU you should upgrade. Corsair CX430 is cheap and enough upgrade for your rig as stated.

7770 can manage multiple monitors (to weak for multi monitor gaming) and it will not have any conflicts with integrated video.

Best regards :)

you can see if your power is enough for your components here:

but i think it will work just fine, the thing is the psu fan will speed up like a plane turbine.
ps - sorry for my bad english.

This is not proper way to determine which power supply to buy.

Altough this power supply has 22A at 12V rail (264) it does not mean it can deliver that. Some unbranded supplies tend to burn even if you get at 60% of their rated 12V output. If it is older one then it's even more probable to fail when you load it. It will probably run for some time but risk of failing and damaging your components is to great. Those PSU's should not be considered to put in your PC.
I would not recomend going with that PSU.
