## Questions & Answers

**Q: What is the current rating for the +12 volt rail?**
A: That is a very good question. Evidently Coolmax isn't very proud of the power supply. They don't list the current rating of any of the DC outputs in their supply. I even checked the Coolmax web site and it doesn't list outputs nor the current rating. That would and does make me very skeptical about using their 500W power supply.

**Q: I was wondering the same as the first question? It says 10pcs. This has got to be wrong?**
A: Yes, they are wrong... I have no idea how they can say "10 pcs bulk" when it's "1 piece by it self".   The unit works well though and I don't think they'll send me 9 others just because they lied.

**Q: Does this have a sata connector for a dvd burner (not full 15-pin size, but half the width)? i don't need molex connectors or pci-e connectors.**
A: It has dvd burner sata connector,not sure about the half width.has a lot of different plugs. You can buy adapter plugs.

**Q: Does it have 4-pin molex connectors that can be adapted to power other SATA devices or just the two drive cables?  I need to have a total of 5 drives.**
A: It has three molex connectors. I'm using two of them with a 2 molex to 6 pin power connector to power my gtx 550 ti, and it works like a charm. I'm pretty sure you can buy a 1 molex to 2 sata connector to power two hard drives and it would work just fine. If it can power my gpu, it should be fine. The short answer is yes, you can, just make sure you buy the right adapters for your configuration. If you want me to link you to some good adapters, I will.
