It is Mean Well 252W, that comes with 6 pins not like Dell DA-2 220W (8 pin) so we have 32W more + we don't need to add reserved/sense pin like for the Dell PSU:

 Shopping list cables for every GPU:

1 x Barrel 5.5mm x 2.5mm

1 x Startech.com 6 inch PCI Express Power Splitter Cable

1 x 6 pin (F) PCIe to dual 8pin (6+2) (M) cable

As Dell DA-2 220W is not stable for GTX 1080, we have this external PSU with it GTX 1080 will be stable, even in gaming peak, the Mean Well 252W don't have a fan!

Hi, I am putting together a Thunder2 + 1080TI setup. Would this PSU work? Or which PSU should I get instead? 


Seems like Dell isn't good enough for 1080TI

80$? Wow that is expensive. You can get a modular SFX power supply in the 400W range for about the same money. To truly "kill" the DA-2 a power supply not only needs to be slightly more powerful, it also needs to be price-competitive. An 80$ power-brick is not quite that.

Give your Node Pro a second Thunderbolt3 controller for reliable peripherals by re-using a TB3 dock (~50$).

Hi, I agree with Yukikaze. These SFX PSUs, at a comparable price, are smaller and lighter.  I've been using a Corsair SF450, and it works beautifully. I mention it because the Silverstone was at the top of the small SFX PSUs, but it's since been surpassed by the Corsair. It has the same premium features like modularity, but is cheaper, quieter, and performs better.


I do believe that Silverstone has recognized this and is coming out with an update to their competing unit soon.

Hi, I am doing a build with a GTX760 and I would like use the Dell DA-2, is that good enough?
Dell DA-2 says is 220w, and the GTX760 requires 170w. I am not sure if the remaining 50w is good to run the Akitio PCIe card
