Wanting to run PSU at 250 Volts

[frowertr]

Got a Seasonic Platinum SS-860SP that will accept 250V AC. I am going to be using it for a LTC mining rig so I want to keep power consumption to a minimum thus the need for a 250v circuit.

My question has to with the power cord. I can make one end of the cord via this however I am not sure what the opposite end is called to wire that appropriately.

Unless there is an easier way to do this and just purchase a 10/15A 250V cord but I haven't seen one around anywhere.

Thoughts?

May have just found it: http://www.amazon.com/6-15P-C13-Powe.../dp/B004WJMDN2

Question #1, is the source even 250V?

I can easily make it 240/250V by adding the appropriate breaker to my panel and running the decidicated circuit to the appropriate location.

I just picked up the same psu a few days ago.
If you do this please let us know how it works for you

I was impressed to discover that the 860 platinum beat my 400 X-series gold in low watt situations (only 120v for me).

IDLE LOAD(GPU) LOAD(GPU+CPU) LOAD(oc+hd)
64 254 284
59 244 267 325

good luck

Yup, I'll post back when I get it done. I already have an unused 240V breaker in the breaker box that I can use for this purpose. Just need to run a dedicated line to the area I want the outlet.

I am not sure this will make a huge difference. But I have done some reading that seems to show that PSU's that are fed 240 are slightly more efficient than those fed 120V. Even if it is only a couple percent I suppose that will add up over time on a mining rig that is running full speed 24x7x365. Plus having a dedicated circuit for it means I don't have to worry about tripping a breaker when I plug anything else in since it will be isolated.

Interesting. Can you point me to something that can keep up with ~900 watts of constant demand? Seems like at night/cloudy day one would need a HUGE battery bank unless it was also tied into the grid.

900 watts is virtually nothing. I'd stay away from grid-tied systems for your application.
Are you technical enough to compile and assemble your own system or would you need a turn key system?

Yeah, I can do it myself. Have a buddy who is also pretty good with electrical wiring so I'm sure we can figure it out. Although, I'd still like to look at ready made stuff anyway...

Thought I'd update this thread in case anyone else wanted to do this. I had an unused 20 amp double pole breaker in my breaker box so I ran some dedicated 12/4 MC cable (already had it on hand) to the place I needed my outlets. Since I needed two 20 amp 240v outlets I ran the MC cable from the breaker into a plastic J box so I could make my outlet connections inside the J box.





Here is what was needing them for:



I'm still waiting on risers for the top mining rig so only one card is currently running on it. Each rig will pull approx 4 amps at 240V so I still have some head room in case I decide to add another rig or two to the circuit.
