Problem with Gigabyte ga-78lmt-usb3 v6.0 and AMD FX-8350

I built my system using Gigabyte ga-78lmt-usb3 v6.0 motherboard and AMD FX-8350 processor. I have two 4 GB RAMs connected to it. SMPS is iBall pps 255 which is of 450 Watts. I am getting continuous short beeps on running the system. It automatically crashes after continuous short beeps. On checking the beep codes for award BIOS system I got to know that it indicates Power supply unit failed 2.AMI BIOS. Which SMPS should I buy to resolve this problem? Is there anything else that too may be leading to this problem?

Does not look to be 450 Watts

In reply to: Problem with Gigabyte ga-78lmt-usb3 v6.0 and AMD FX-8350

The side panel has this for Amperes per rail.

3.3 - 15A
5.0 - 15A
12V - 18A

So in round numbers at max this would be 45+75+216 or 336 Watts.

There are thousands of better PSUs and since I can't pick one for you due to the Earth being a big place, come back with what you can buy and we'll pick it over.

Be sure to pick something in the 450+W size with a Single +12V Rail.

I want to know ideal wattage of power supply. The manual of motherboard mentions a minimum supply of 500 Watt. But do this system require more than it for good performance?

Not to upset you

In reply to: Watts

But that's a silly question. Picking a PSU is done by your standards. My standard is to have a PSU rated at double the maximum Amperes I see per rail. Watts is then checked and we want about double the max we see on the Watt meter.

-> It's very technical and you can never choose by Watts alone as the power supplies have rails of 3.3, 5 and 12. You can find a 750 Watt PSU but it's junk with it's quad +12V rails. Find a single rail model and it works. And we can even reduce the total Watts since each rail is ample to a lower than 750 number.

There is no ideal wattage. There are ideal Amperes.

Then how?.....

Just wondering. The AMD CPU doesn't appear to have video out so what is this machine?

It's a working machine

I don't have an external video card. I have used it, it's working. The only problem is the continuous beep after which it crashes.

So it has an internal video card.

To pick out a PSU all the details would be required. Or you just put it on a Watt meter, triple or quadruple the reading and pick up a single rail PSU.

Without details you can't be sure what to replace it with.
