Product Description

Gen 8 HP 643956-101 CS Platinum 94% 1200 Watt Power Supply

HP 643956-101 Common Slot (CS) Power Supplies share a common electrical and physical design that allows for hot-swap, tool-less installation into HP server and storage solutions. A key part of the HP Thermal Discovery Services, CS Platinum/Platinum Plus Power Supplies provide the IT industry’s highest level of power efficiency (94%), helping customers to reduce power requirements by up to 60W per server and reducing overall data center power requirements by up to 10% (as compared to ProLiant G6 power estimates). CS Platinum/Platinum Plus power supplies also enable HP Power Discovery Services which focus on increasing compute density while reducing data center outages.

For ASIC / GPU Mining:

When paired with one of our high quality breakout boards and PCIE cables, this PSU will  increase the ROI of your mining operations by reducing your overall electric cost. This unit has been rated to operate in a 24/7/365 mining environment and, unlike ATX Desktop power supplies, it will not fail after a few months of use.

With the increased popularity of ASIC and GPU mining many overseas and domestic sellers are taking advantage of the lack of knowledge of some users. We have seen an increase of sellers passing these HP 1200W PSUs as 94% Platinum rated. The only HP platinum 1200W PSU in the market are the ones with the following part numbers:  570451-101, 643956-101, 643956-201, 748283-201, 703247-101 (Certified by HP Directly). If you bought a HP 1200W PSU and it does not have these part numbers, IT IS NOT 94% PLATINUM CERTIFIED.

Got something to discuss?

Hi, is it okay to use a standard 18AWGx3C power cord for these, or do you advise using something like 14AWG?

    hi sir just want to ask first before i buy.
    isn’t it to loud to have a server psu inside a room? wouldn’t it be hard to slreep?

    • Joseph g (store manager)

      Hello Thonz. What is the greatest advantage about server PSU is they can perform at nearly 100% max capacity 24/7 for years. However, if you do run them above 70% capacity the small fan inside will sound like a jet plane! Below 70% it will be acceptable.
