How to add more SATA slots (power and data) to i5-4590 ?

looks like only three on the original psu

HP ProDesk 400 G2 MT original Desktop-PC power supply 300 Watt - sparepartworld.com


I think it is standard ATX. If so any reasonable standard atx power supply will fit and have mutiple sata connectors.

That is probably easiest.

I think it was later than the prodesk 400 G2 that the proprietary disease took over.

If you click on the link for the power supply the specs say "4x SATA" connections.

Why don't you just add one HDD or SSD with capacity equal to the two drives you want to add? Wouldn't that be a lot simpler?

BTW, since the motherboard has 4 SATA data ports doesn't the power supply already have 4 SATA power connectors? Two are already used for the DVD and hard drive with two unused. I assume the SATA power cable is already using splitters like most power supplies do.

I want to avoid buying new HDD, but yes that would be the best solution.
I don't know about the 4th sata (data) port, I remember I used it once with the splitters, the HDD was not recognized (not even in BIOS).

If you dont want to use a splitter you will have to use an additional power supply. Or use the one from the dvd.

How does it work? Sounds messy like 2 power cables for the PC ?
Isn't there some safe sata splitter?

Easiest to replace the psu. Have you got any lying around ?

Yes, just found one "Power Man" MODEL NO IP-S350EQ3-2, with 5 SATA power slots.

But looks a bit rusty on the rear, though. I don't know if it's compatible or even working.
