Title: Is my power supply causing shutdown?
Post by: domo_916 on April 15, 2017, 01:56:34 PM
I upgraded my graphics card from a Amd raedon hd 7770 to a xfx Rx 480. After installing the card and downloading latest drivers I got on Counter-Strike and within 5 minutes my Computer Black screened shutdown like instantly. I thought this was due to overheating so i rebooted and monitered the temps while playing and it turned off again but the temps where way below overheating levels (60c for both cpu and gpu with 35% fan speed). I switched the card back to my old one and it ran perfectly with no shutdowns at all. the only thing i could think of that could be causing this would be my power supply which is a  Viotek Vio60 600 Watt Atx Switching Power Supply. 600w is more than enough to power the Rx 480 so i was wondering is the shutdown being cause by the quality of the power supply? I have attached a picture of the label on the power supply.

I won't say it unequivocally...but that's a garbage PSU...

is that the reason for the shutdowns?

The rx480 has well known power problems, the biggest one in your case would be that the maximum draw of 142W via the PCI-E connector and 155W through  the PCI-E connector come to a total of 297W. The Power supply can only deliver 360W on the 12V Total. What likely happens is the rx480 is spiiking it's power draw and that results in the motherboard power for other components being browned out, resulting in a blank screen.

And that's even assuming the label is accurate.

Yes, that's should do wonderfully.

An idea to try First though, make sure you have the latest drivers. As I recall the initial release was plagued with power draw problems, with the Card drawing more power over PCI-E than the specification allowed. This means that certain motherboards could have problems like you've had; AMD released drivers that "capped" the power draw within spec more recently. Since that costs nothing you might try that first.
