Is a 650W PSU able to power 3 internal hard drives

  erkmatrix 14:05 03 May 2010

Hi I've got a 300GB VelociRaptor drive from my old computer and want to use this as a scratch disk for photoshop on my new setup. But I already have a Samsung Spinpoint F3 1TB for storage and a Intel X25-M 80GB SSD for Windows 7 on. Just wanted to know if a Corsair CMPSU-650TX 650W would be able to handle running 3 internal dives and if I'd notice any speed differences at all using such a drive as a scratch disk only.

Any advice would be most welcome.

Others will know better than me, but I don't see any problem at all. Hard drives consume very little power, and a 650 watt PSU is a bit of a monster. From what (little) I know, you generally only really need to think hard about your PSU if you're looking to install a high end graphics card.

Right yeah my graphics card only uses 1 power cable from my PSU and is a Radeon HD Shapphire 5770 Vapor-x so not a high end card.

In that case as AL47 said not a problem
