I was wondering if the Corsair HX520W would handle a GTX460 MSI Cyclone OC 1GB on a i7 860, 4GB RAM and 3 SATAII drives.

The PSU has a 3 rail design with 18A per rail. Will that be enough?

I don't know how the 2 PCIe connectors will power the card. Either one could have 18A or both could share the 18A rail. :eek:

Thanks!

ct1615 - very nice chart. I added it to my bookmarks for future reference.

Bibanu - That chart shows system power consumption at idle and maximum during the Furmark stress test. During a gaming session a pc system will typically use less power than that shown for FurMark.

The Corsair HX520 is an older model. Four years ago jonnyguru.com did a technical review:

ct1615 suggested the psu has one large +12 volt rail that was split rather than three separate rails. I'm pretty sure ct1615 is right. The reviewer at jonnyguru.com could not confirm the psu has three separate rails.

btw - The data label on the psu clearly indicates that the maximum wattage for the +12 volt rails is 480 watts. To determine the amperage one divides the the wattage by 12 volts. 480 watts divided by 12 volts = a total of 40 amps on the +12 volt rail(s).
