HPE ProLiant SL335s G7 Power Supplies
Genuine HPE Common Slot hot-plug power supplies for the HPE ProLiant SL335s G7, new and refurbished. Read this before ordering: these supplies live in the s6500 chassis, not in the server — one set feeds up to eight half-width trays, and the chassis ships with neither supplies nor fans.
SL335s G7 Power Supply Specifications
- Format: HPE Common Slot (CS) hot-plug supplies, fitted to the 4U HPE ProLiant s6500 chassis rather than to the individual 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%; at 240V the 750W Platinum measures 93.2% to the Gold unit's 91.5%, and the 1200W Platinum 93% to the Silver unit's 89%
- Input: 100 to 240V at 50/60Hz on every unit stocked here, UL and CE Mark compliant
- Redundancy: the supplies are hot plug and redundant, with the redundancy actually available depending on how the nodes in the chassis are configured
- Cooling: a separate chassis decision — all eight s6500 fan bays must be filled, and the redundant and non-redundant fan kits contain one fan each
- Kit contents: each option kit contains the power supply, an IEC power cable and PDU IEC cables
These supplies go in the s6500 chassis, not in the server. One set of Common Slot units feeds up to eight SL335s G7 nodes, and the configure-to-order chassis ships with neither supplies nor fans. Check the feed voltage before ordering 1200W: both 1200W units deliver 1200W only from 200V up, 900W at 120V and 800W at 100V.
Which Common Slot Supply Does Your s6500 Need?
| Supply | Rated output | Output at 100V / 120V | Efficiency at 240V |
|---|---|---|---|
| 750W Common Slot Platinum | 750W | 750W / 750W | 93.2% |
| 750W Common Slot Gold | 750W | 750W / 750W | 91.5% |
| 1200W Common Slot Platinum | 1200W | 800W / 900W | 93% |
| 1200W Common Slot Silver | 1200W | 800W / 900W | 89% |
The 1200W units are the trap here. Both deliver their full 1200W only from 200V upward; on a 120V feed they are 900W supplies and on 100V they are 800W, well short of what a chassis sized on the nameplate expects. The 750W units hold 750W across the whole range, and efficiency grade counts for more here than on one server, because a single set of supplies carries up to eight trays for years.
Choosing the Right SL335s G7 Power Supply
- Size for the chassis, not for the tray. Every node draws from these supplies, so the total across the chassis is what matters, and 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 footnote.
- Read the label on what is already fitted. The installed supply records the output and efficiency grade the chassis was built around, the quickest route to a correct order.
- A switched PDU is not a way to power down one node. Cutting AC to the chassis supplies takes down every server in it, because the nodes share them. HPE's SL Advanced Power Manager switches a single node instead.
- Do not leave empty bays unblanked. A node blank is needed for every unfilled 1U half-width space, and all eight fan bays have to be populated to cool properly.

SL335s G7 Power Supplies FAQ
Does the SL335s G7 have its own power supply?
No. It is a half-width tray, and the Common Slot supplies go in the 4U HPE ProLiant s6500 chassis. One set feeds up to eight nodes, and the configure-to-order chassis ships without supplies or fans.
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.
Can I use a switched PDU to power down one SL335s 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.
How many fans does the s6500 chassis need?
Eight. Both the redundant and the non-redundant fan kits contain a single fan, and HPE requires the entire chassis to be filled, so eight kits are ordered together.
