Replace the 4U server PSU with a desktop PSU

hp-proliantpower supply

I have an HP ML10 v2. It uses a Delta DPS-350AB-20 A 350w mATX PSU. I use this server at home, and the PSU is noisy, so I'm looking to replace it with a Be Quiet! SP10 CM 500w, which is quieter, more efficient and more powerful (I'll eventually be making significant upgrades and I'd like to keep it quiet).

There are two things I can't figure out:

  1. I can turn the server on/off by sending 'power signals' using iLO 4. Does this at all rely on a feature of the PSU, or is it solely the motherboard that manages this?

  2. The SAS cable by Amphenol in the server serves 4 drives, and includes power. It has a 10-pin connector I haven't seen before, that is matched by a connector on the PSU. Is this bespoke, or can I purchase an adaptor for the new, standard PSU?

UPDATE:
Following Sami's advice, I went ahead and replaced the PSU as planned. I bought some cable, 4-pin molex connectors and a 10pin connector as this won't be the only cable I make, otherwise I'd go for a molex splitter, cut the ends off and replace it with a 10pin connector. I already had a crimper.

The PSU sits upside down (fan facing upwards) at the top of the chassis, sitting on a shelf. There's just enough clearance above it for me to be comfortable with the fan there. I'm also using a very efficient, high quality power supply.

The PSU I used has a switch on the back. Because the chassis wasn't built to accommodate any other PSU, there is no space for this switch, so the PSU has to sit slightly recessed into the case – I just bought some longer screws and some nylon spacers, and it's perfectly secure.

Remote on/off works fine, that's totally managed by the chipset.

Best Answer

Usually remote startup/shutdown doesn't require any support from the power supply. The remote controller and motherboard will handle all things needed. Even in a "normal" PC the power supply will only supply power when the motherboard so asks and nothing more.

The connector seems to have the normal red, yellow and black wires on it. That would indicate that it can be connected to regular PSU simply by connecting the same color wires to correct positions. Red is +5V, yellow +12V and black of course is the ground.

So based on the power supply being a regular desktop mATX power supply I would say it is highly likely you can switch it with another one and just wire the connector to the appropriate wires in the new PSU.
