Review: Died within two weeks of install - HDPLEX worked in my SFF for two weeks before dying. It was a simple setup with low power draw, about 125W max, so I am disappointed.
Review: great job, hdplex team! - i think this little thing is amazing. i paired it with an OEM PA-9E AC-DC converter to have a powerful and compact power delivery system. i've previously used picoPSUs and struggled mightily with full-size ATX PSUs in cramped mini-itx chassis. this power supply hits a sweet spot right in the middle that lets you run the powerful haswell-e and skylake CPUs in a small case along with a decent GPU and other necessary components. Keep in mind the combined wattage requirement of the CPU and PCIE GPU means you may need to sacrifice some on one side or the other to stay safely under the 250(ish) watts this provides. it's extraordinarily well-made and the components are top-notch. it's not obvious in the photos, but the entire back side of the PCB is covered with a thick sheet of aluminum heat sink coupled to the PCB using heat tape between standoffs. the supplied cable set is also well-made. the cables are not sleeved or twisted but rather are left loose. the main motherboard cable seems excessively long, with the other cables in lengths more suited to small cases. even so, the loose cable is fairly easy to tuck out of the way. no instructions are provided, but the board itself is well-labeled, so it is easy to figure out where to plug things in. it comes with 4 small black screws that fit into holes tapped into the bottom heatsink. there are also 4 mounting holes that go through the top of the circuit board and through corresponding (unthreaded) holes in the bottom heatsink. a 6-32 screw won't fit through these holes, so a thinner, longer screw is needed. mounting options depend on figuring out how to best use these holes in your case. at about 2" x 6" the module itself should be easy to position in just about any case.

## Questions & Answers

**Q: Where do I buy the power brick?**
A: i bought mine from ebay. you can also buy one from Amazon. Just search for "DA330PM111" in Amazon or Ebay. The search will show you the power brick. It is rated 330W but when used with the HDPLEX 300W, it can support a gaming system with a GPU with TDP up to 150W such as GTX1070. I paired the Dell power brick 330W with my HDPLEX 250W (older version of HDPLEX 300W) on a system that has i7 6700 and GTX 1070. The system runs perfectly fine.

**Q: Please provide 12v, 5v, 3.3v and -12v output current ratings.  where can i purchase internal ac/dc adapter?**
A: HD-plex publishes the current rating for each voltage.http://www.hd-plex.com/HDPLEX-250W-Hi-Fi-DC-ATX-Power-Supply-16V-24V-Wide-Range-Voltage-Input.htmlAbout AD/DC adapter, I prefer an external one but HD-Plex also offers an 80W that can be installed internally.

**Q: What cables are included? If none, is there an option to buy them in a kit?**
A: Complete ATX cable set are included.  Those includes 24PIN, 8PIN EPS CPU, DUAL 6+2 PIN PCIEXPRESS, SATA CABLE. Please see this page for details  http://www.hd-plex.com/product/300W.DC-ATX.PSU/en/fanlesspcpackagecontent.html

**Q: will this work with the dell pa-7e 210W adapter?**
A: Yes since Dell PA-7E also use 7.4*5.0 DC connector.

### ⭐⭐⭐⭐ So close to perfect.
*by X***K on January 31, 2016*

Great PSU. Very stable voltages even when pushed hard. Very solid, well built board. only con is the included cable quality. It doesn't match the quality of the board at all. 2 of the retention clips arrived broken, and 2 more are very weak and ready to break. several of the wires on the ATX con are badly crimped, like they got crimped in a drawer or slammed in a door. still recommend it the PSU , but they really should find a better quality source of cables.
