Your old CPU has a TDP of 140W. I forget which model exactly I had |
| 24 |
but I think its TDP was 195W. |
| 25 |
|
| 26 |
Sure, the 1950X is going to pull quite a bit of power, but my 1600 |
| 27 |
only pulls 65W when going full tilt. It is a very noticeable |
| 28 |
difference. I suspect my old CPU probably used a good portion of that |
| 29 |
at idle. |

Seems like eSATA is harder to find these days. USB3 seems to be the |
| 40 |
way things are going. However, that works just fine. |
| 41 |
|
| 42 |
On my motherboard at least the PCI-based NVMe came at the cost of |
| 43 |
disabling one of the x16 slots, and the SATA-based one came at the |
| 44 |
cost of disabling one of the SATA ports. So, no PCI-based NVMe for me |
| 45 |
as I have an 8x card in addition to my graphics card. |
| 46 |
|
| 47 |
They really need to make more flexible slots as I believe that the |
| 48 |
slots themselves are electrically compatible - that is you can shove a |
| 49 |
16x card in a 1x slot as long as you eliminate the plastic that blocks |
| 50 |
this from happening. Granted, I wouldn't want to put my LSI card in a |
| 51 |
1x slot - it would be nicer if they had a 2x or 4x slot in there, but |
| 52 |
I realize that 1x and 16x seems to be where all the demand is. |

Yeah, the best price I could find as $99 for 8GB of DDR4 ECC, and only |
| 60 |
at 2400. Not much of a consumer market for ECC. |
