Hi wonder if you could help me?

I have the following system and needed a DX11 gpu so purchased an MSI R7770 GhZ Edition GPU 1024mb GDDR5 to replace my Radeon HD 4850 

MS-7504VP-PV (CPU 1) motherboard
Intel Core2 Quad CPU Q8200 @ 2.33GHz
Dynex 400w PSU
Windows 7

After installing the card i can hear the fans whirring but no display on the monitor- checked and reseated the GPU - still not working

Refitted the Radeon HD4850 - Computer back to normal!

A lot of posts on other forums point to the PSU needing to be minimum 500w but there are conflicting posts that state that a 400w psu is adequate.

Can anyone help please-any advice/guidance greatly appreciated.

Could be a faulty card, even considering your psu is not great, it will power the 4850 which draws 30 watts more then the 7770.

Yes  i double checked and it was a straightforward 6 pin like for like.

 

Should the card be OK with the motherboard as it's a few years old now?

Did you try to update the mb bios to the latest, just read another forum where a 7850 on the same mb ran fine after a bios update.

Thanks will check that out.

 

Is BIOS update easy for a relative novice?

Please make sure the 4/6pins for video power connector is also connected on the mobo as well.

 

400W power supply seems a little inadequate. stated 400w most of time is only 300+w only.

For large gaming, the peak voltage comsumption may not enough.

 

Hope this helps.
