Title: First mining rig psu question
Post by: jackkiej on February 17, 2014, 09:20:01 PM

Hi guys,

I want to build my first mining rig, and I've already bought all the parts I need, but I just want to be sure everything will work fine.
These are the parts I've bought:
- Gygabyte GA-990FXA
- SeaSonic X-1250 PSU (yes 1250W)
- AMD Sempron 145
- 4X Gigabyte R9 280X
- 4 usb powered risers (these (https://ip.bitcointalk.org/?u=http%3A%2F%2Fi.ebayimg.com%2Ft%2FPCI-e-express-1X-to-1X-16x-Riser-Extender-Card-with-extra-power-1M-USB-3-0-Cable-%2F00%2Fs%2FNDQxWDYwMA%3D%3D%2Fz%2FDwMAAMXQdGJRzwCz%2F%24T2eC16JHJHEFFl1d5l%2CJBRzwCzSVzw%7E%7E60_3.JPG&t=537&c=bbGDOUda9yPqYg))
- KINGSTON HyperX blu 2 x 2 GB DDR3-1600

I would like to know if 1250W is enough for this, on the extreme power supply calculator (http://www.extreme.outervision.com/psucalculatorlite.jsp) I came out on 1240W recommended..

Kind regards,

Jack

If you undervolt the 280X you should be able to run it 1-2 years no problem since each card would pull 250W or less leaving 250W for system and component degradation.

1250w should be enough even if you overclock alittle.
