Question Is this possible?

[dellpet310]

I have a dell poweredge T310 from 2008. It has a 400watt psu with a -5v rail and only 2 sata cables, 1 PCIe connector and a 20+4pin atx connector.

I would like to upgrade my psu to one that has 2 PCIe connectors(for gpu's) and more wattage(550 watt). The newer psu's dont have the -5v rail in their atx connectors but they have multiple PCIe connectors.

Is it possible to use a new Corsair RM550x psu in my old poweredge?

You could go for an aftermarket PSU as your board has the necessary connectors though I'm curious to learn why you intend to add a newer PSU...? Want to add a discrete GPU?

I want a new new psu because the only PCIe connecter is used by the raid setup and i only have 2 sata power cables. So i need a new psu if i want to use a good gpu(i don't want to use a 75watt gpu with no PCIe connector).

And i dont fully thust aftermarket psu's.
