Based on AMD 990X /SB950 chipset, ASUS M5A99X EVO ATX motherboard lets you take advantage of the powerful AMD AM3+/AM3 multi-core processors. You’ll enjoy up to 5200MT/s HyperTransport 3.0 (HT 3.0) interface speed, quad USB 3.0 & SATA 6Gb/s and PCI Express 2.0 x16 graphics with support for CrossFireX and SLI technologies.

The M5A99X EVO is equipped with DIGI+ VRM technology in addition to the TPU and EPU processors that offer enhanced performance and power management. DIGI+ VRM power delivery allows a user to precisely adjust and control power settings digitally for precise power control and flexible tuning of their system. Also included is the intuitive and feature laden ASUS UEFI BIOS menu interface allowing users to control and adjust their motherboard settings through the use of a mouse-enabled interface for a superior user-friendly experience that BIOS does not offer.

  • newegg AMD FX /Phenom II /Athlon II /Sempron 100 Series Processors Support This motherboard supports AMD AM3+ multi-core processors with unique L3 cache and current AMD Phenom II /Athlon II /Sempron 100 Series processors. The AMD 990X Chipset is designed to support up to 5200MT/s HyperTransport 3.0 (HT 3.0) interface speed and dual PCI Express 2.0 x16 graphics (1x16 or 2x8).
  • newegg DIGI+ VRM ASUS DIGI+ VRM is an innovative, industry-leading technology that fully integrates Intel VRD12 specifications on a native level, greatly enhancing power to go far beyond the limits of analog designs. ASUS DIGI+ VRM acts as a digital controller to perfectly match digital power signal (SVID) requests from the CPU, eliminating digital-to-analog conversion lag. The exclusive dual driver and MOS design doubles the heat dissipation area with expanded cooling surfaces for improved thermal performance. Spacing components out over a wider area speeds up cooling to enhance reliability and stability. The same exclusive dual driver and MOS design also provides twice the CPU power supply with two complete power stages. This results in far greater phase load tolerances, so the CPU never has to wait for power to arrive, increasing performance and overclocking potential.
  • newegg TPU & EPU The TPU chip offers precise voltage control and advanced monitoring through Auto Tuning and TurboV functions. Auto Tuning offers a user friendly way to automatically optimize the system for fast, yet stable clock speeds, while TurboV enables unlimited freedom to adjust CPU frequencies and ratios for optimized performance in diverse situations. The EPU chip provides a real-time, dynamic power saving by automatically detecting current PC loadings and intelligently moderating power consumption. This also reduces fan noise and extends component longevity!
  • newegg UEFI BIOS The new ASUS UEFI BIOS is an Extensible Firmware Interface that complies with UEFI architecture, offering a user-friendly interface that goes beyond traditional keyboard-only BIOS controls to enable more flexible and convenient mouse input. Users can easily navigate the new UEFI BIOS with the same smoothness as their operating system. The exclusive EZ Mode displays frequently-accessed setup info, while the Advanced Mode is for experienced performance enthusiasts that demand far more intricate system settings. The UEFI BIOS also natively supports hard drives larger than 2.2TB in 64-bit, with full storage space utilization, helping deliver far more exciting computing than traditional BIOS versions!
  • newegg Quad USB 3.0 & 6 x SATA III AMD SB950 Southbridge natively supports next-generation Serial ATA (SATA) storage interface, which delivers up to 6.0 Gb/s data transfer rates. ASUS facilitates strategic USB 3.0 accessibility for both the front and rear panel - 4 USB 3.0 ports in total. Experience the latest plug & play connectivity at speeds up to 10 times faster than USB 2.0.
  • newegg Quad-GPU SLI and Quad-GPU CrossFireX Support The ASUS M5A99X EVO features two PCI-E 2.0 x16 slots (x16 or dual x8) that support Quad-GPU SLI and Quad-GPU CrossFireX, delivering a brand-new gaming style you’ve never experienced before!

5 out of 5 eggsExcellent Quality and performance

Pros: Every bit as good as the Sabertooth board I owned. This mobo OC's easily. Very good board for the money. Runs the 8350 CPU, with the 1708 BIOS update flawlessly.

Cons: None. Owned it over a year with no issues.

Other Thoughts: Also handles the EVGA GTX 770 GPU flawlessly. Windows 7 runs great with it all.

2 out of 5 eggswas good till my warranty was up

Pros: -good OC
- easy Bios
-lots of ports

Cons: - ports stopped working
-drivers weren't working

-asus customer service was terrible

Other Thoughts: called to get my RMA and see if they could help me at all. Guy told me its out of warranty so I could pay to get it fixed or just go buy a new on e 'Its not my problem " he said.

I have asus everything and cant afford another mobo atm but I thought this would last more than a year. might have to go to another company :/

Manufacturer Response:

4 out of 5 eggsGood MB

Pros: This was a nice up grade for me. I'm running an old Phenom 955 BE and upgraded the motherboard and added a SSD. I'm still using an old Radeon 5770 video card. But the performance jump was wonderful. Loving the 6Gb lanes!

Cons: Sleep issues that others have mentioned. Bios needs tweaking and takes some learning - but why else does would I buy a new MB if I didn't want the fun of tweaking.

Other Thoughts: Overclocked and running fast for a year now.

1 out of 5 eggsNice when it works

Pros: FIne when it works

Cons: Have returned it for a second time. First two USB ports were not working. After repairs it worked a bit and now no USB ports work and sound is dead.
Also over time I have had other problems that seem likelyto be MB related, but are difficult to be definitive about.
* Repeated video driver crashes (with two different video cards).
* RAM (4 x 4 GB) that worked when first installed (acording to memtest), but after about 6 months memtest reproted errors. Interestingly when I tested the RAM sticks individually or in pairs they all worked fine, it was just all 4 together that gave errors.
* Finally although the MB supposedly has a UEFI BIOS, neither WIndows 7 or 8 recognized it as UEFI.

Other Thoughts: Given my experience with this and other ASUS products I struggle to understand why their products get such high ratings.

Manufacturer Response:

Dear Valued Customer,

I am sorry your motherboard is not working. If I may, I would like to help.

If possible, may I have the Windows Dump files please? I would need the error reports when the Bluescreens happened.
Regarding the USB and sound issues, what drivers are currently installed? Also, are the USB ports and sound card being detected in Device Manager?

At you earliest convenience, please contact me through email, and we can discuss this case further. Within the message, please include the serial number of the card and any troubleshooting steps tried. Your reference number for this case is 3104603.

5 out of 5 eggsIn love

Pros: Going from a micro ATX to this was amazing. Fit perfectly with my case (Rosewill Blackhawk ATX mid tower), very reliable, I love the BIOS set up, easy to flash.

Cons: I have honestly had zero issues with this board that are worthy of docking an egg. I do wish that some of the SATA ports didn't need L cables in my case, but that's more of a case issue.

Other Thoughts: I use my computer mainly for gaming, and honestly I'm very pleased with this motherboard. She's holding out steady, looks great, easy to use. I am not the type of gamer who needs 500 slots for GPU's and other card accessories, yet it has enough for a crossfire, which I eventually plan on using.

5 out of 5 eggsGreat boards

Pros: Great board little to no problems installing or getting setup.

Cons: Non

Other Thoughts: Used this board for both mine and my fathers PC and they have been flawless to date. I hate to see them get a bad rap but then my boards are a bit older maybe somethings changed in process.

1 out of 5 eggsDied a little after a year

Pros: ASUS is a great manufacturer of motherboards and other computer components and I hold them in high standards. I build computers and work for an IT company and usually purchase motherboards from ASUS.

Cons: My personal computer has this board in it and unfortunately, the board died little after one year of moderate use.
This is unacceptable for such a (usually) great board manufacturer.

Other Thoughts: I am seeking a simple replacement.

1 out of 5 eggsTerrible Product

Pros: worked for a week

Cons: after about a week of owning this board it my rig began to shut off randomly didnt matter what i was doing...so i went thru the basics memtest swapped psu swapped ram swapped gpu swapped cpu redid heatsink new thermal paste the whole nine yards after about a week of slaving over it the problem seemed to solve itself so i thought eveything was fine....about six months later it began again so it took it out of my rig and saw a somewhat large burn on the backside of the mobo behind the usb 2.0 headers so i rma it back to asus assuming i would receive a refurb just have them send the old one back in the same condition...me assuming that it would work put it back in my case to find to no avail the problem persist so i contacted asus again and the first support tech i spoke to told me to buy a new board :( i hung up called back and spoke to a dif tech who told me if i had a credit card or a bank i could have them put a hold for the value of the board they would send me a new and i had to return the old one but i do not have a cc or suffient funds to do either so now im stuck without a pc going on 6 weeks now and prob wont have $ for a new one for at least another month....i would highly advise against buying this product for i wish this head ache on know one :(

Other Thoughts: it was great while it worked!

Manufacturer Response:

Dear Valued Customer,

Sorry to hear that the RMA board didn't work. What we can do is send you a return label so you won't have to pay for shipping.

Please provide me with your RMA number and serial number so I can look at your previous case. You said you are unable to use your board for 6 weeks. So the board isn't being used so you will be able to send it in for service.

If you have any questions or comments you can email me again at cl-jeffrey@asus.com which I reside in the U.S

ASUS strives to meet and exceeds our customer expectations within our warranty policy.

Regards,

Jeffrey
