Just assembled my new computer and it failed to POST. The CPU error LED was lit up and initially thought it was DOA. However I've since read that this board does not support the fx 9590 (even though it's the same architecture as the fx 8320/8350). However on the ASUS website there is a bios update that says 'support for newer cpu's'. And the board has a feature for updating the bios without having to access the bios settings or OS. Will this help?
Just cleaned out the sockets, reassembled, tried to use the flashback utility with a usb stick containing the latest flash... the led for flaskback didn't show on the mobo. I'm wondering if it needs a working cpu to even work. And i'm wondering if I should buy the cheapest cpu possible that is known to work in this board and try upgrading the flash then and then reinserting the other cpu, or if i'm wasting my time and it won't work with the 9590 anyway.
It's actually the one in the thread title (except i should have wrote 'm5a'). Sorry I didn't make it more clear.
I've asked on the asus website and they say it's not officially supported cpu, it would draw too much power and damage the board. I think the board is a lemon anyway, though.
You will need to update the bios on that board if you want to use a 9590. When I had this board I had to update the bios when I got an 8350. I couldn't manage to get the usb flashback to work either so I ended up having to buy an already updated bios chip from ebay. I'm sure you you can do the same thing or buy a cpu that's supported on the earliest bios and update from there.

I use a M5A99FX pro 2.0 which officially supports FX 9590 chips- I seriously doubt there is any difference between my board and the plain M5A99X r.2.0 in power delivery. If the board is in working condition, getting a proper bios version should allow the 9590 to work just fine. Worst case scenario, undervolt a tiny bit.

Hmm, I'm not sure if you're making assumptions then.
Here's another thread where it says only specific revisions of the gigabyte fx motherboard's have a good enough mofset to handle the 9590's load. I'm not sure if I should trust this motherboard (or the next one I buy) to educated guesses or if I should just spend the extra money on an officially supported board... obviously I don't like spending the extra money though, so if enough people vouch for the weaker unofficial boards I'll take that into account.
Exactly an Asus M5a 99x (not 99fx) rev 2.0

Those "officially" supported boards have no better MOSFETs than the equally-good "unofficial" boards. It's just a BIOS limitation, in most cases.
For example, the LX-V2 version of my board has support for 125TDP chips (including the 8350 and 8370), while mine only supports 95W. There is NO difference, phase-wise. Just a different BIOS.

But is this a universal truth? I've been told that the mofset is what separates enthusiast/overclocking-suited boards from lower end ones. Can I be 100% sure that it's the case with the asus and/or gigabyte boards? Is the asus rep lying through his teeth on that forum just trying to get me to spend more money?
*EDIT Seems I lied, it's not m5a 99x rev 2.0, it's m5a 99x evo rev 2.0.
Seems it is 6+2 phase. Is that the only variable I need to consider?

Oh you have the m5a 99x evo rev 2.0 not the pro. Even if the board can handle it, I dont think you can use a 9590 on it because the website doesnt show that its supported on any of the bios.
So I got myself a sempron 145 to troubleshoot this. The red led for the cpu immediately comes on when I turn the machine on, just as before. I think the board is dead, unless I happened to get two dead cpu's (they were both used).
