Question 1

I've looked over the pictures for this power supply (SeaSonic SS-1050XP3 1050W), and cannot locate the 120/240vac switch. Is this power supply auto switching or does it have a hard switch? Also, what type of wall connector does it come with?

Accepted Answer

It comes with a 110-120 VAC standard PC type power cord. There is no 120/240vac switch. I wish I could answer the question about whether it will auto switch between the two input voltages, but I am not positive. It is my ASSUMPTION, that it will auto switch, if the power cord is changed, but I cannot find that in any of the reviews or specs.

Question 2

I've looked over the pictures for this power supply (SeaSonic SS-1050XP3 1050W), and cannot locate the 120/240vac switch. Is this power supply auto switching or does it have a hard switch? Also, what type of wall connector does it come with?

Accepted Answer

It's auto switching there is no physical need to change voltage input and it comes with an American 3 prong wall plug.

Question 3

Does this PSU support Crossfire and SLI?

Accepted Answer

Yes - this PSU can support 2/3/4 gfx cards in Crossfire and SLI - that being you have plenty of connectors from a connectivity standpoint.

From a power standpoint: If you are using 2 gfx cards then likely this PSU is way overkill unless you are running a 2 Socket LGA2011 workstation board and CF/SLI.

Only if you are running multiple CPUs and/or 3 or more high draw GPUs (GTX980/TitanX/290X/Etc) would I think this PSU appropriately sized.

Question 4

Is this PSU Haswell Ready? In the Overview picture, I see that it is, and a few reviews that I have read say that it is. However it is not listed as Haswell ready on Newegg or Seasonic's website.

Accepted Answer

Yes it is haswell ready.  I emailed seasonic directly to make sure before i purchased one and they assured me it was.  Best psu i have ever owned.

Question 5

dimensions?

Accepted Answer

L 190mm (7 31/64") x W 150mm (5 29/32") x H 86mm (3 25/64")

Question 6

I see two nearly-identical SeaSonic power supplies - this, and the 1000W "Platinum-1000" for the same price. What is the difference? I'm building a new system using the Asus X99 Deluxe, and need to know which one to order. Thanks.

Accepted Answer

The SS-1050XP3 is the newer model.   XP2 is second generation; XP3 is third generation (in terms of platinum PSUS from Seasonic).
