PSU sizing

[trumee]

Hello,

I need a PSU to support my hardware. I ran some numbers based on PSU guidance sticky and came with the following

Code:

X10DRi-T - 25 Watt
2xE5-2620 v3 - 170 Watt
DDR4 (256GB) - 96 Watt
24xHDD (4TB, 25 Watt each) - 600 Watt
5xFans - 10.8 Watt
3xRaid Card - 30 Watt
Total - 930 Watts

I will need to get a 1000watt psu to support this. This assumes that the CPU will be running full steam when disks are spinning up which is probably not accurate.

What do you think about these numbers and the PSU wattage for this hardware.

Thanks

I think you'll be safe with a 1000watt supply. Anything more than that would likely be overkill.

How about if I go lower say 750/850 watts?

Best looking at a PSU calculator. A quick Google search revealed this one, people seem to like it:http://outervision.com/power-supply-calculator

I get 750 watts psu recommendation using that calculator. http://outervision.com/b/kE8ZON

In a similar situation, I went with a 1000w Corsair RMx. Has good rating for low usage efficiency. Fan only spins at spin up.

Supermicro gives you a 1200w psu in the chassis that supports that kind of hardware. I would stick with 1000w.
