2 out of 5 eggsDisappointed

Pros: Was and worked as advertised for a little less than a year.

Cons: Very delicate and thin. Components are of low quality

Other Thoughts: I owned this a little less than a year and was very satisfied with it until recently. I recently upgraded my GPU. I always take all the precautions when working with hardware. Simply removing my old card gently caused the PCIe 3.0 slot to stop functioning. I have been trying to email Biostar support but they are very slow replying.

3 out of 5 eggsboth bad and good.

Pros: good quality
handles itself well under a load
pretty decent for a budget mobo.

Cons: overclock is somewhat complicated

Other Thoughts: i had one of this previously in a rig that i bought from a friend, i really liked the setup and was pleased with the mobo easy to use and boot up. this time around, i wanted to build a new rig and decided i would go with the same mobo. however, as soon as i installed it failed to post. i revised all other cables and wiring to make sure everything was properly connected and everything else was fine, but again, no post, no display no nothing. It was somewhat upsetting but none the less, i submitted an RMA and it was handled in a prompt manner, i got my refund and i orderd a TZ77A this time instead.

to sum it up; i received a bad product sent it back and am in the process of getting a new one; all done hassle free.

1 out of 5 eggsCustomer support

Pros: Lots of PCI ports. Cheap Z77 that allowed Crossfire.

Cons: One of the Sata 6gb ports didn't work. USB ports stopped operating after a couple months of usage. Didn't care about it too much until it happened more and more often. Motherboard just died recently. Front audio USB didn't work.

Other Thoughts: I have contacted the RMA service about the 5 year limited warranty multiple times but still have not even gotten an automated return message.

Manufacturer Response:

Sorry to hear of your troubles, please see RMA Request form Link for warranty service.

3 out of 5 eggsDoes not help make a clean build.

Pros: * Z77 for a moderate price.
* everything is unlocked (VCore+Multiplier). So, you can do your own CPU/memory overclocking comfortably.

Cons: * Some of the connectors are placed in such an awkward place that it does not help you with the cable management. Look at the picture and notice the red front audio connector right behind the built-in 3.5mm jacks.
**The IO connectors are usually placed to the back of the case and the front audio is in the front side of the your cable will extend over the width of the motherboard..which is not nice.
**Likewise with the front USB 3.0 connector (the blue one just north of the red PCI-e slot).
**Gigabyte does better with the SATA connectors. The SATA connectors in a gigabyte mobo face sideways.

*The BIOS interface is so retro. Other mobos have 3D bios interface.

Other Thoughts: Sorry newegg!....this the only item from the build I bought from another company.

4 out of 5 eggsSound issues

Pros: Overall, this motherboard is good for overclocking and has a decent amount of I/O

Cons: Every time I put my computer in 'Sleep' mode, the sound out of the audio jack doesn't work until I go to the Realtek sound manager GUI and switch it from "Mute rear device..." to "Make front and rear output devices playback..." or vice versa. Not a huge issue, but it can be a nuisance to some.

Oh, I sent a rebate for this board, and it never came back. :,(

4 out of 5 eggsDoes what it needs to do on the cheap

Pros: It's a pretty decent basic on-the-cheap mobo that seems to be capable of some basic overclocking (although that's not my thing).

Cons: Not the greatest layout, SATA plugs are in a bit of a weird spot and could use some more fan headers. Not enough for my Antec case. Doesn't recognize XMP profile for my Mushkin RAM modules and I can't figure out how to set the timings right since it's a faster-than-usual speed. Sometimes boots into code 99 which isn't explained anywhere and requires a hard reset before POST.

Other Thoughts: It does what it has to do and hasn't failed on me... yet. Have had it just over a year.
