When purchasing a new system or cluster, preparing the power requirements is integral. Power draw from the systems is key in addition to ensuring there is enough power available from the power source/circuit to fulfill the wattage needed.
...
Here is a chart of the most common circuits below.
Power that can be provided by each circuit. (Be Aware: there can be multiple outlets for a single circuit)
...
For example, we will examine the power draw for the:

Components that requires power listed below:
| Parts Listing (Spectrum TXN003-0128N , Deep Learning DevBox (64GB DDR4, 4x Titan X Pascal, 256GB SSD, 4TB HDD) | ||
| Description | Quantity | Power Draw |
| X99-E WS Intel X99 Server Workstation Motherboard | 1 | 125W |
| INTEL 6 CORE I7-5930K 3.5GHZ 15M | 1 | 140W |
| CORSAIR Hydro Series H60 | 1 | ~5-10W |
| 16GB DDR4 2133 MHz Desktop Memory Module (64GB system memory) | 4 | ~5-10W per |
| 256GB 2.5 SATA III Internal Solid State Drive (SSD) | 1 | <1W |
| 4TB 7200RPM 64MB CACHE 3.5IN SATA Enterprise Class HDD | 1 | ~5-10W per |
| NVIDIA GeForce Titan X Pascal 12GB GDDR5X | 4 | 1000W |

Cooling
To calculate the appropriate amount of cooling required for a single system or cluster, use the following:
P(BTU/hr) = 3.412141633 × P(W)
So
1W = 3.412141633 BTU/hr
For the Example of the Dev Box above,
P(BTU/hr) = 3.412141633 × 1325W
P(BTU/hr) = 4521.0876 (BTU/hr)
