## 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.
