Dual PSU System Build

[Geekazoid]

Hi geeks,

Just curious if anyone here has built or is likely to build a PC with 2 PSUs installed. I imagine you'd have to have a tonne of power hungry components to warrant such a build. It'd be interesting to see such a setup with two PSUs in a case that can accommodate them.

Yup, a lot of Quad-SLI builds have two PSUs. Or top-of-the-notch mining rigs. Hell, I think Linus' case can fit two PSUs, although he uses only one.

I think Asus Ares had two 1000W PSUs somewhere in 2009-2010 (model CG6155).

Yeah - redundant PSU's

I think my brain switched itself off . Not quite sure what you mean by that?

2+ PSU's in the event of a failure.

Oh! Gotcha. My bad.

with 1200Watt PSU's out there i cant see a reason for them to exist  unless you also use 2 mobos

I agree, but there is now like 1500w (1600w peak) psu's now: http://www.pccasegear.com/index.php?main_page=product_info&cPath=15_535&products_id=14472

 

Cause its needed.

I've seen a lot of mining rigs with 2 PSUs, but they aren't in your standard case

This is about the only reason I can think of.

 

As others have mentioned, with the PSU watts you can buy nowadays (1500W+ from what I've seen lately) the second is redundant.

Even a Quad-SLI build will take (usually - depending) under 1000W.

Only low end quad SLI setups will consume 1000w or less. Most flagship 4-way setups take a lot more than that.

1000w is not really enough for 4way sli

That and Quad SLI is completely pointless outside of epeen bragging rights.

Yeah, it depends though.

 

And, as Mooshi said... I concur!

Uh? You can't run your cpu of 2 PSU's unless you have 2 CPU power plugs on your board.

Cases that support 2 psu's I know of is the 900D or TJ11/07.

Yes you can, backplaned PSU units. Every server running 2 or more PSU's use them.
