Tul, the parent company of PowerColor, currently has two external graphics (eGFX) boxes for high-end graphics cards, as well as low-power miniature eGFX solutions. Both sides of the coin have allowed the company to gain a lot of experience when it comes to external Thunderbolt 3 graphics. At this year's Computex, the company demonstrated its upcoming enclosure for high-performance customers that will offer even more advantages over their previous-gen chassis.

The TBX-750FA eGFX box is equipped with a 750 W power supply, which allows it to deliver up to 500 W of power to a graphics card as well as up to 100 W of power to its host laptop via USB-PD. With 500 W of power available to a video card, the chassis will be compatible even with the highest-performing video card, with a good bit of headroom to spare for overclocking. Furthermore, the box will be able to power high-end 15.6-inch laptops.

Traditionally for Tul, and PowerColor, the TBX-750FA eGFX box supports loads of additional capabilities. In particular, the unit has a 2.5-inch SATA bay, a GbE port, an SD 4.0 card reader, as well as five-port USB 3.0 hub.

The TBX-750FA can house a 2.5-slot wide graphics card and integrates a standard power supply along with multiple additional components, which makes the chassis rather bulky.

At Computex, Tul demonstrated its TBX-750FA eGFX enclosure under its own brand, which means that the chassis will be available not only to PowerColor, but to other suppliers of eGFX products too. It is hard to say when this product is set to be available from any brand, but at Computex the company demonstrated a pre-production sample.

    Interesting. Silverstone has multiple 300W options at Gold or better.

    Well, the key is to be above 20%. The difference between 20% and 100% rarely varies by more than 2% efficiency.

    On the one hand, I appreciate the fact that the only speciality components inside seem to be the motherboard and the front USB board, which means this will *hopefully* be priced decently.

    On the other hand, they could've at least used a modular PSU so there aren't useless Molex connector cables floating around! Even better, an SFX PSU, because the one they've got in there is blocking the single SATA port.

    Sell it in two configurations - one with a PSU bundled, one with no PSU so users can (re-)use their own - and we'll see.

    I can feel this will be reasonably priced unlike existing ones.

    Did anyone else read the headline and immediately think "That's silly. Why would you build a 750W box and only deliver 100W to it?"

    You're right, that IS what it looks like.
    *insert rant about USB-C here*

    That's a bulky case. I get that it almost has to be in order to handle the PSU and GPU, but considering the end goal (typically just playing a few video games on a computer that otherwise doesn't have a powerful enough GPU) it seems like a lot of additional footprint and mobility compromise compared to just picking things your computer can run well on its existing graphics hardware.

    It is ridiculously large, and I feel like they're solving the wrong problem here.

    "If we use a standard ATX power supply, there's a whole bunch of dead space in the box because the card is way longer than the supply, but super-skinny. I guess we'll throw a hard drive mount and a USB hub in that extra space!"

    I mean, I get why they aren't making their own custom power supply. It isn't easy to do it well, and then you have a bunch of boring safety reviews. You can avoid both issues by using someone else's closed box power supply. But a full ATX supply, sourcing the better part of a kilowatt?

    Come on, guys! Get a 400-watt SFX supply.
    Or use a 12V supply in a long, narrow case. Some regulators on the board can generate 3.3v, you don't need a multi-voltage supply.
    You could make this thing so much smaller than an ENTIRE ITX SYSTEM.
