HPE ProLiant DL580 G7 Power Supplies

Genuine HPE 1200W Common Slot hot-plug power supplies for the HPE ProLiant DL580 G7, new and refurbished. Two facts govern every order on this page: two-processor models ship two supplies and four-processor models ship four, and a 1200W supply only delivers 1200W on a high-line feed.

DL580 G7 Power Supply Specifications

• Format: HPE 1200W Common Slot hot-plug power supplies, the shared form factor used across several ProLiant generations
• Standard count: two hot-plug supplies on two-processor models and four on four-processor models
• Output by input voltage: 1200W at 200 to 240 VAC, 900W at 120 VAC and 800W at 100 VAC
• Mixing: not supported — all supplies in one server should match, and Platinum and Silver units cannot be mixed
• Redundancy reporting: the server inventories its own configuration at power on and reports the redundancy level the fitted supplies support, with an RBSU override available
• Cooling: four hot-plug redundant fans ship as standard in a 3+1 arrangement

A 1200W supply is a 1200W supply only above 200 volts. The same Common Slot unit is rated 900W at 120 VAC and 800W at 100 VAC. Pair that with the processor rule — two supplies on two-processor models, four on four-processor models — and a CPU upgrade on a low-line rack is a bigger power order than it first looks.

What Does a 1200W Supply Actually Deliver?

The figures above are the documented ratings for the 1200W Common Slot Silver supply, and the pattern matters more than the decimals: a supply on a 120V feed gives up three hundred watts against the same unit on 208V. On a four-socket chassis carrying 130W processors and a full memory drawer, that is the difference between a configuration the server reports as redundant and one it does not.

Choosing the Right DL580 G7 Power Supply

• Processor count drives supply count. Going from two processors to four normally means going from two supplies to four, so a CPU upgrade is a power order as well.
• All supplies in a server should match. HPE does not support mixing Platinum and Silver units, so read the label on what is already fitted before ordering the next one.
• High line or lose the rating. The 1200W figure applies from 200 VAC upward; on a 100V feed the same unit is an 800W supply.
• Let the server tell you where you stand. The DL580 G7 checks its own configuration at power on and reports what redundancy the installed supplies actually support, and an RBSU override exists for cases where the Power Advisor disagrees.
• The option kit includes its cables. HPE supplies the power supply with an IEC power cable and PDU IEC cables.

DL580 G7 Power Supplies FAQ

How many power supplies does a DL580 G7 take?
Two ship as standard with two-processor models and four with four-processor models. All of them are hot-plug Common Slot units.

Can I mix power supplies in a DL580 G7?
No. HPE states that all power supplies in a server should match, and specifically that mixing Platinum and Silver units is not supported.

Why does my 1200W supply only deliver 800W?
Because it is on a low-line feed. The 1200W rating applies from 200 VAC upward; at 120 VAC the same unit is rated 900W and at 100 VAC it is rated 800W.

How do I know whether my configuration is redundant?
The server works it out itself. The DL580 G7 inventories its configuration and reports the supported redundancy level during power on, and an RBSU override switch lets you change the base setting if the HPE Power Advisor shows otherwise.

Are DL580 G7 power supplies hot-plug?
Yes. All of the Common Slot supplies are hot-plug, so in a redundant configuration one can be replaced while the server keeps running.

How many fans does a DL580 G7 have?
Four hot-plug redundant fans ship standard on every model, in a 3+1 arrangement.
