HPE ProLiant SL165s G7 Power Supplies

Genuine HPE Common Slot hot-plug power supplies for the HPE ProLiant SL165s G7, new and refurbished. Read the first line carefully before ordering: this server is a tray, and the power supplies live in the s6500 chassis, not in the tray — every pre-configured model lists its power supply and its fans as chassis items, sold separately, and one set of supplies feeds every node in that chassis.

SL165s G7 Power Supply Specifications

• Format: HPE Common Slot (CS) hot-plug supplies, fitted to the HPE ProLiant s6500 chassis rather than to the server tray
• Outputs stocked: 750W in Platinum and Gold, and 1200W in Platinum and Silver
• Efficiency: the Common Slot range is rated up to 94%; the 750W Platinum unit measures 93.2% at 240V against the Gold unit's 91.5%
• Input: 100 to 240V at 50/60Hz on every unit stocked here
• Redundancy: the supplies are hot plug and redundant, with the redundancy available depending on how the nodes in the chassis are configured
• Chassis fitting: the s6500 configure-to-order chassis ships without power supplies and without fans, so both are chosen and ordered separately
• Kit contents: each option kit contains the power supply, an IEC power cable and PDU IEC cables; SL trays themselves ship with a PDU power cord because they are normally fed from rack PDUs

These supplies go in the s6500 chassis, not in the server. HPE lists power and fans as chassis items on every SL165s G7 model, and one set of supplies feeds every node in the chassis. Size them for the whole chassis, and check the feed voltage first: both 1200W Common Slot units deliver 1200W only from 200V up, 900W at 120V and 800W at 100V.

Which Common Slot supply does your s6500 need?

The 1200W units are the trap on this platform. Both of them deliver their full 1200W only from 200V upward; on a 120V feed they are 900W supplies and on 100V they are 800W supplies, which is less headroom than a chassis sized on the nameplate expects. The 750W units hold 750W across the whole 100 to 240V range. Efficiency grade also counts for more here than on a single server, because one set of supplies carries four trays for years rather than one.

Choosing the Right SL165s G7 Power Supply

• Size for the chassis, not for the tray. Every node in the s6500 draws from these supplies, so the sum of the trays is the number that matters. HPE publishes a Power Advisor for working it out.
• Check the rack feed before buying 1200W. At 100V or 120V a 1200W Common Slot unit gives 800W or 900W, so the high-line feed is part of the specification rather than a detail.
• Read the label on what is already fitted. The installed supply tells you the output and efficiency grade the chassis was built around, which is the quickest route to a correct order.
• A switched PDU is not a way to power one tray down. Cutting AC to the chassis supplies takes down every server in that chassis, because the nodes share them. HPE's SL Advanced Power Manager exists precisely to switch a single node instead.
• Fans are a separate chassis decision. All eight s6500 fan bays must be populated, the kits contain one fan each, and redundant and non-redundant fans cannot be mixed.

Complete Your SL165s G7 Build

Power draw follows the processors and the drive count across the whole chassis — see SL165s G7 processors and hard drives before sizing a supply, and the SL165s G7 parts listing for the s6500 fan kits, node blanks and rail kits. Also available: SL165s G7 memory, storage controllers and networking adapters, or every platform we carry from HPE parts by server model.

SL165s G7 Power Supplies FAQ

Does the SL165s G7 have its own power supply?
No. It is a tray, and HPE lists the power supply and the fans as chassis items sold separately on every pre-configured model. The Common Slot supplies go in the s6500 chassis and feed every node in it.

Which power supplies does the s6500 chassis take?
750W Common Slot Platinum and Gold hot-plug units, and 1200W Common Slot Platinum and Silver units. All four accept 100 to 240V at 50 or 60Hz.

Why is my 1200W power supply only delivering 900W?
Because of the input voltage. Both 1200W Common Slot units are rated at 1200W from 200V upward, 900W at 120V and 800W at 100V. The 750W units hold their full output across the whole range.

Are these power supplies hot-plug and redundant?
Yes. HPE Common Slot supplies are hot plug and redundant, though the redundancy actually available depends on how the nodes in the chassis are configured.

What comes in a Common Slot power supply option kit?
The power supply itself, an IEC power cable and PDU IEC cables. SL trays ship with a PDU power cord as standard because they are normally connected to rack PDUs.

Can I use a switched PDU to power down one SL165s G7?
No. The nodes share the chassis power supplies, so cutting their AC feed drops every server in that chassis. HPE's SL Advanced Power Manager is the tool for switching an individual node.
