The FlashArray//X70 (R2/R3) and FlashArray//X90 (R2/R3) require 1600W Power Supply Units (PSUs) .
Pure Storage equips its FlashArray//X chassis with different power supply capacities based on the compute load of the installed controllers:
* Performance Tier (X70/X90): These models utilize high-core-count Intel Xeon processors and support the maximum density of NVMe DirectFlash Modules. To support the peak power draw of these components while maintaining N+1 redundancy (where one PSU can support the entire load), the
1600W units are mandatory.
* Entry/Mid Tier (X10/X20/X50): Lower-end models often ship with 1000W or 1200W PSUs (though X50 often uses 1600W in later revisions or specific configs).
* Identification: Implementation Engineers can identify these PSUs by the label on the rear handle (often color-coded or explicitly marked "1600W"). Installing an X90 controller into a chassis with older
1200W PSUs (e.g., during an improper upgrade attempt) would likely trigger a hardware alert or prevent the controllers from booting due to insufficient power budget.
