M5A99FX Pro Rev 2 + fx 9370

Processor amd fx 9370
Mobo asus M5A99fx pro rev 2
Graphics asus 650ti
Ram 2x4gb corsair 1833 mhz
psu thermaltake 620w 80+
Liquid cooling is zalman dual fan
Bios is updated to the latest version


I can't even go to bios. All I get is a steady cpu red led light in the mobo.
If i will use my old processor amd x4 2.8ghz, everything runs fine using the uefi setup.
With or without the ssd, I can go to bios with my old cpu.
We tried the fx 9370 in my friend's asus sabertooth and it took it without any problem.

Need some some help please.
I am thinking it is just in the bios setup. I goggled it and somehow end up getting confused with bios settings. I even tried the older versions of bios but it did not help.
The bios setup is full of confusing tweaks. Please help me with a step by step guide how to set it up.

Thank you.

  1. Use old CPU and check the BIOS version, need at least 1903 for the 9370. Also if you have a good BIOS, might try it using your friends PSU, the 9370 is a power hungry CPU

    Is this 620 watts psu not enough to go into bios setup?
    All I need to do first is go into bios and this will tell me that it will run. I mean the mobo plus the cpu are communicating and ready to run or boot.

  4. Your choices for the 9000 series:

    Asrock 970 Performance
    ASRock 990FX Extreme9
    ASRock 990FX Extreme6
    Asus Crosshair V Formula-Z
    Asus M5A99FX PRO R2.0
    Asus Sabertooth 990FX R2.0
    Gigabyte GA-990FXA-UD3 R4.0\5.0
    Gigabyte GA-990FXA-UD5
    Gigabyte GA-990FXA-UD7
    MSI 990FXA-GD80V2

    AMD.COM

    Warning: This power draw of this CPU is almost twice that of the average CPU. Due to this, AMD recommends using at minimum a 850W to 1000W power supply. For cooling, AMD recommends using either either closed loop liquid cooling , h100i minimum or full system liquid cooling.

  5. We are saying try with a more powerful PSU - AMD recommended a 1,000 watt psu for these CPUs (9370 and 9590s) when they were released, I've found about 850 (like SR-71 stated) to be about the minimal I'd use

    This is true with fx 9370 plus power hungry graphics doing gaming or may be some heavy video editing but just to go to bios, is this really going to cause the cpu light to go on? Graphics, I think is just using a minimal amount of its power when logging into bios. Please correct me if i am wrong. If it is really the power issue, then it should cause it to reboot just like when you are gaming and you don't have enough power...it will shutdown or reboot. At one point I just let on for like 2 hours, hoping that the red light will go away but it never did....no reboot or shutdown within this period.

    And one more thing. I just finish talking to my friend where I have this fx 9370 tested and he said that his psu is 650 watts and it is not even the 80+.

  9. We are trying to help, we have no idea of what actuial model of PSU you have, (and 80+ has to do with how it takes in power from a source and then uses it), with Thermaltake you are prob somewhere in the %00+ range onm the 12 volt rail. Yes, it could well be something else, but the suggestion to try a bigger PSU with YOUR rig has now been posed by three of us, if you wish to ignore it, that's up to you, but I'm off this thread. Sort of a waste of time to keep repeating ourselves

    He said he bought from ebay for $12 about 4 years ago, straight from china. And the only thing he can read on its markings is "Made in China".
    My psu is thermaltake m2 silent pro. Model rs-620-spm2-e3
