MSI Z77A-GD80 & R7770 Power Edition Transthermal OC Review

The MSI R7770 Power Edition Transthermal OC arrives in a very distinctively designed box featuring the enhanced PWM design.

Another fancy gatefold design which details the military class components and enhanced PWM design. This card is tied into the Afterburner software which opens up various voltage settings to improve the chances of successful overclocking. They also mention their ‘Dust Removal Technology' along the bottom of the box panel.

The bundle includes a software disc, secondary fan, video and power converter cables and some literature on the product. This is no ordinary video card however so it is worth reading the literature, for a change.

The video card is  built to match the motherboard colour scheme, detailed on the previous pages. The PCB is dark, and the cooler is tough plastic, also black, with a dual blue strip running along the full length. A large fan is placed centrally.

The R7770 is Crossfire capable, but only in a two way configuration. It requires a 6 pin power cable for stable operation.

It includes a DVI, HDMI and DisplayPort connector on the panel, all of which are full size. The MSI logo is cut into the backplate.

The really interesting topic of conversation is the dual fan system. The images above show the secondary blue fan mounted on top of the primary cooler fan. This will take up more room in the chassis however.

On the cooler are two black clips which can be pushed in, so the cooler can be ‘extended' in length.

When the cooler is fully extended, this will leave enough space to mount the other fan above the heatsink, alongside the primary black fan.

The blue fan slots into a plastic section of the cooler and can be then locked into place, with two small screws.

When the secondary fan is installed, the cooling performance should be significantly improved.

The fan plugs into a tiny header on the side of the cooler as shown above.

The image above highlights the video card in two states of operation. The bottom image is the default shipping mode and above, with the extra fan installed alongside the main fan. It adds around 3-4 cm's to the overall length.

The Cooler is easily removed, exposing the single heatpipe copper cooler and aluminum fins.

The CPU Z screenshot highlights the 28nm AMD Cape Verde core, with 1GB of GDDR5 memory connected to a 128 bit memory interface. The HD7770 ships with 16 ROPs with 640 Unified Shaders.

The R7770 Power Edition Transthermal OC has received a significant core clock increase from 1,000mhz to 1,100mhz. The memory speeds are set at 1,125mhz (4.5Gbps effective), which is the same as the reference AMD card.

  1. Dont get it… you either want a single fan card, or a dual fan card…so just buy a single fan card, or a dual fan card- there are better dual fan coolers out there, such as XFXs Brushed Aluminium cooler, looks a thousand times better than the neon blue plastic tat on this card… Its not like your going to put this in your system and suddenly wake up one day and say- ‘i know i fancy two fans today’….

  2. I get your point, although I think its cool you can basically change the noise/cooling balance to suit different environments. size too.

    If it cost £30 more then its pretty pointless, but it seems closely priced to the other HD7770s.

    Still think sapphire HD6850 was the best deal for a while at £90.

  3. Great motherboard but im not sure on the graphics card. its clever, but for the target market im not sure its a buying decision. You either want a smaller card for a media center, or a higher cooled, size card for gaming.

    Gamers wont buy the HD7770 I wouldnt think, so why not just put a larger single fan on the HD7770 in the first place and ditch the extra fan completely?

    Nice idea to be creative like this, but ultimately I think its a bit pointless.

  4. Ok, first thing first. this motherboard is from what I know the same as the GD65 but now has thunderbolt. its a great board. all we need to say (apart from the added price for thunderbolt).

    The graphics card is frigging cool. The shiftable cooler idea is nice. Its maybe only useful for people who change systems regularly. so you could ditch a fan, slot it into a HPTC, then take it out, extend it then add another etc.

    How many people would do that though? Might make more sense on a HD7850 or 7870. HD7770 is more suited just for media duties and low powered use.

  5. please put two hd7770 in crossfire the results will show that they can deliver more fps
    than the high end gtx 670 and hd 7870
    with lots of money left over get that new motherboard
    give it try
