In the car industry, there is a large variety of cars to choose from - both the cheap and the expensive will get you from A to B, but in various amounts of luxury, with different engines and features under the hood.  In comparison the motherboard industry, we have nothing like this - products are built to specifications and have to remain price competitive.  Very rarely do we get a price competitive motherboard with a ton of features that also stretches the wallet in the same way a luxury car might do.  For this analogy, we have the P8Z77-V Premium from ASUS to review, which comes in at $450 MSRP, but features Thunderbolt connectivity, dual Intel NIC, an onboard 32GB mSATA SSD, a PLX chip for 4-way PCIe devices, onboard WiFi, Bluetooth, and extra SATA/USB ports. 

ASUS P8Z77-V Premium Overview

For our first PEX 8747 board, heads will turn when the price is mentioned.  The ASUS P8Z77-V Premium comes in at a staggering $450 USD.  That amount of money could pay for an ultra-low end Z77 motherboard and an i7-3770K all on its own!  So why does a board in such a platform cost so much?  If our pockets were this deep, then Sandy Bridge-E is only around the corner and a consideration.

The way ASUS are justifying the cost is through the sheer amount of functionality added to the Premium.  The Premium enjoys the following additions to the basic chipset:

- Dual Intel NIC, one Server Grade (82579V), one normal (82583)
- mSATA port with 32GB LiteOn mSATA SSD
- PLX PEX 8747 for x8/x8/x8/x8 PCIe 3.0 operation
- Trusted Platform Module
- Included Dual Band (2.4 GHz/5 GHz) WiFi and Bluetooth v4.0 module, with antenna
- Thunderbolt Port
- A total of 12 SATA ports, including a SATA 6 Gbps Marvell 9230 controller for four capable ASUS SSD Caching ports
- Included USB 3.0 Front box
- iNetwork Control
- Fan XPert II Sofware
- ASUS Premium Service (for North American customers)

No other Z77 motherboard on the market offers such a package.  We have the option of using IGP or multi-PCIe setups, SSD caching with the 32GB SSD onboard to help, dual Intel grade NICs but also WiFi, Thunderbolt connectivity for displays and storage, as well as extra SATA ports and USB 3.0 front box functionality.  That is a lot of extra, and hence with it comes a lot of price.  Through this review, we will determine just how well these features add up.

In terms of the overview, the ASUS P8Z77-V Premium does come with MultiCore Enhancement by default, which allows the processor to run at the maximum Turbo bin at any load, giving extra MHz under full loading situations (video conversion) and thus better performance.  With IO, the addition of the Thunderbolt port allows any TB device to leave our USB testing suite in the dust, and the standard IO is not too bad either.

Gaming wise was a little different – the inclusion of the PEX 8747 chip means that single GPU performance is slightly down on non-PEX 8747 motherboards due to extra routing, but with four 7970s at 2560x1440 and all the trimmings, we hit 229 FPS in Dirt 3.

Visual Inspection

For a motherboard that has all this functionality, it is a small victory that ASUS have managed to fit it all into a normal ATX sized motherboard rather than the E-ATX form factor.  Our first focus is the socket area, which has on two sides a very substantial pair of heatsinks covering the power delivery.  Compared some other boards at a similar price range, these heatsinks are not connected via a heatpipe to each other, like the P8Z77-V Deluxe.  This could show that ASUS are confident in their cooling solution for their high end channel boards.

The socket area has five 4-pin fan headers nearby for use by CPU coolers – two north of the top heatpipe, two next to the bottom of the IO panel, and another by the 24-pin ATX power connector.  The other 4-pin fan header on board is located on the bottom near the front panel connectors.

The P8Z77-V Premium uses a single 8-pin 12V CPU power connector for CPU power, and also has ASUS’ single ended memory latch design for the DIMMs.  Down the right hand side we have the TPM header, a MemOK button (in case memory settings are too tight), the 24-pin ATX power connector, a USB 3.0 header and a single SATA 3 Gbps port pointing out of the board.  I used this single SATA 3 Gbps (powered from the chipset) for my primary disk, such that I would always know where it was connected.

The SATA ports are color coded – the top four in dark blue come from a Marvell 9230 controller (so SATA 6 Gbps) and are used for the ASUS SSD Caching II.  Underneath this are the two SATA 6 Gbps from the chipset in white, and then two SATA 3 Gbps from the chipset in light blue.  Next to this is the chipset heatsink, which is large to cover the chipset, but also both the Marvell SATA controllers.  It should be noted for the Marvell controller uses an x2 PCIe interconnect rather than an x1 – this allows the use of multiple SSDs to be used in the caching system.  The setup also allows multiple caching scenarios (SSD + mechanical and another SSD + mechanical) and stacked SSD caching, which is something ASUS has implemented due to the request of users.  This is all adjustable via a simple GUI provided as part of AI Suite.

Our mSATA port comes below the chipset heatsink and the SATA ports.  This is a single mSATA 3 Gbps from the chipset to power a 32GB LiteOn SSD.  ASUS calls this their ‘Complete System Boosting Solution’.  While it is nice to have an extra 32GB SSD as part of the system build, ASUS expect the primary focus will be with the SSD caching – users having a mechanical hard drive and using the onboard SSD as a smart cache.  My perception on the other hand is that if a user is laying down $450 for a motherboard, chances are they can buy a fully blown SATA 6 Gbps SSD as an OS drive.  This leaves the 32GB SSD as either storage, somewhere to offload the pagefile, or as an OS drive itself – note that 32GB is below the recommended amount for Windows 7 64-bit.

On the bottom of the board, ASUS have gone for the additional extras rather than the standard swathe of USB 2.0 headers.  While we do get two of the USB 2.0 headers, we also have a 4-pin fan header, a ClearCMOS header, a two-digit debug, TPU and EPU switches, power and reset buttons, and an onboard audio header.  Users deciding to equip the Premium with double-sized GPU at the bottom will come up against one issue, particularly with the USB headers and the front panel:

My two power and reset connectors ended up propping the GPU above the height of the other GPUs, leading to less than ideal contact with the PCIe pins in the bottom fourth slot.

The PCIe layout starts with the PLX PEX 8747 chip hiding behind a small heatsink connected to one of the power delivery heatsinks.  This sends the 32 electrical PCIe 3.0 lanes from the PLX to the blue PCIe slots at 16 a piece.  In getting to these blue slots, the lanes can be switched such that eight of the sixteen go to the white slots, leading to x8/x8/x8/x8 peak bandwidth through each of the slots.  Users of three GPUs can decide to go x8/x8/x16/- or x16/-/x8/x8, depending of if those bottom panel headers are of importance.

Due to a couple of features that ASUS use, the IO panel does not look as substantial as previous iterations – however part of this is due to including a Thunderbolt controller, the WiFi module, and USB BIOS Flashback.  From left to right, we have two USB 3.0 in blue (chipset), two eSATA 6 Gbps (ASMedia), a dual band WiFi and Bluetooth v4.0 module, a Thunderbolt port, HDMI output, DisplayPort output, SPDIF output, dual Intel GbE, two USB 2.0 (black), two USB 3.0 (blue), the USB BIOS Flashback button, and standard audio jacks.

The Thunderbolt port is limited to its current location of the PCB due to the tracing on board, which is limited to less than an inch from the controller, compared to USB tracing which can be longer than 10 inches.  Perhaps ASUS in the future can organize the USB BIOS Flashback button (and perhaps ROG Connect) above this Thunderbolt port in order to increase the available real estate on the back panel.

As specified in the overview, we have a wealth of additional functionality on the P8Z77-V Premium.  Here are my estimates for the BOM costs of individual parts and features:

- Dual Intel NIC ($20 combined)
- 32GB LiteOn mSATA SSD ($60)
- PLX PEX 8747 ($40)
- WiFi and Bluetooth module ($40)
- Thunderbolt ($40)
- Marvell controller for 4 extra SATA ports / SSD Caching ($20)
- Included USB 3.0 Front box ($20)
- iNetwork Control ($15)
- Fan Xpert II Software (comparable $50 controller would not give similar options)
- USB 3.0 Boost + Specific ASMedia controller ($15)
- ASUS Premium Service (for North American customers) (??)

Totaling these up (please note, these are my own interpretations) would come to $320 – a sizable sum which would pay for three low cost Z77 boards by itself!  Removing these would come to $130, or the price of the P8Z77-V LX.  A lot of research and development goes into many of these features (such as the Marvell controllers have x2 PCIe interconnect, or the research/development to put the WiFi module onto the backplane as a card rather than an x1 addition) which we cannot quantify.  This puts the Premium at good value for the features it provides.

So as long as the user can use the above options, then this would make the Premium a good buy (assuming all else is equal).  Otherwise, we come up against the luxury car scenario.  Nevertheless, ASUS tell me that during the first three months of the X79 release, the Rampage IV Extreme was their best selling X79 board, despite being the most expensive and having a range of included features that many of the users on the board would not consider using.  Therefore, despite what common sense from a reviewer's perspective may believe, expensive boards can sell well.

One other point to note is the lack of additional PCIe power supplied to the motherboard.  Typically on products using two or more GPUs we see an extra power connector which supplies extra power to the PCIe slots.  Each PCIe slot should get up to 75W from various power sources, which means that ASUS are confident in pulling at least 300W from the 24-pin ATX power connector.  The usual response to having additional power connectors is to help with grounding or in overclocked situations.  However, I feel it would be useful for any 4-GPU configuration.  So it is odd not to have included something like a SATA power connector for more PCIe juice.

    It offers considerably better performance first generation 9128 and 9120 and 9130 were not bad controller just limited in peak throughput but keep in mind the controller was put to market before Intel even had SATA6G PCH. Also keep in mind performance for real world usage ( boot time, application launch performance, copy performance is pretty similar between then it is only in benchmarks you will see a measurable difference. That being noted the x2 interconnect offers twice the throughput for considerably improved performance vs the x1 interconnect 9128 type solutions. This allows newer SATA6G drives to generally perform on about the same level as the Intel PCH ( peak performance being at / near or above 500MBs on fast controllers ). Additionally it has some specific advantages not noted in the review such as stacked SSD caching. This allows up to 3 SSDs to be stacked on a mechanical drive to continue to enhance its performance.

    Hope this clarifies it for you.

    On any top price product certain features are necessary, useful or not, on a "has" basis.
    Minor omissions (in the would be nice category) would be a card reader in the front USB3.0 Device, and a PCIe expansion card with 2 firewire and 2 USB2 or USB3 plugs.

    After all, too much is not enough, $450 should not require further shopping for minor add ins.
    The price, if you have full use for the "package" seems acceptable, not that I'll ever have it.
  • TimoKyyro - Monday, August 13, 2012 - link

    I would have liked to see GPU rendering benchmarks with SmallLuxGPU or Blender. This board would be perfect for animation rendering with 2 x PCIe 3.0 x16 for dual GTX 690 or 4 x PCIe 3.0 x8 for quad GTX 680.

    The price doesn't matter if I get faster GPU rendering and better support for new technologies like PCIe 3.0 and Thunderbolt.
  • IanCutress - Monday, August 13, 2012 - link

    Unfortunately I do not have access to those GPUs.

  • rahvin - Monday, August 13, 2012 - link

    Are the eSATA ports port multiplier capable?
  • mayankleoboy1 - Monday, August 13, 2012 - link

    it would be great to see a PCIE3.0 SSD for tests and if it can take advantage of the extra bandwidth.
  • DigitalFreak - Monday, August 13, 2012 - link

    There is no "extra bandwidth". You're still limited to the x16 connection to the CPU.
  • jwcalla - Monday, August 13, 2012 - link


    If you want to set yourself apart, how about supporting something useful like ECC RAM and 10 GbE?

    Until you can do ethernet over Thunderbolt, I don't really see the point of TB on a motherboard like this.

    And 10+ SATA ports... that would only be used in a file server context. But that requires ECC RAM. So it doesn't add up.

  • jwcalla - Monday, August 13, 2012 - link

    * Ahh yes I forgot that desktop Intel chipsets don't support ECC RAM so they can charge more for their server-based motherboards and processors.

    Even Cortex A-15 supports ECC. *sigh*

    This space needs some serious competition. It's just the same boring features rehashed and multiplied.
  • Kevin G - Monday, August 13, 2012 - link

    There are a few TB -> Ethernet solutions out there, including an adapter from Apple. Though with two NIC's on the board, I'm not really use-case scenario for TB on this particular motherboard. I can only fathom fast external storage and at that point the user would be better off with a solid SAS card with external connectivity.

    As for ECC, Intel does indeed limit their desktop processors. A handful of motherboards will support ECC if a socket 1155 Xeon is utilized. Though if ECC is critical, AMD's FX line supports ECC and up to the motherboard manufacturers to support it.
