What I am working around is an HP Z400 power supply (475 watts).

It will successfully run two GTX 750 Ti's at once. So I think I can run a single faster card if the power requirements are "low" enough. It looks like a GeForce GTX 1060 (upto 120 watts) may have a low enough power draw to work on my Xeon box.

Are there any better candidates? I am presuming that all the GPU cards that draw (upto) 175 watts are completely out of my league. eg: GTX 1080 etc.

No, I can't upgrade the PS within any reasonable budget (its a proprietary Motherboard/PS setup). It would be less trouble to switch out the whole box (probably more expensive though).

Thank you for your thoughts on this.

The other option then are the 1050Ti's, the modern equivalent of the old 750Ti's.

Cheers.

I can tell you that my 1070 runs 120-125W under Linux which pushes the cards really hard. So one 1070 would be around the 100-120W load under Windows meeting that requirement.

Here's a 750Ti vs 1070 comparison in Linux:

Steven should be able to give you an actual power draw with 1060's.

The 1080 draw is not as high as one might think, my peaks would be at 150W, but 130 is more normal and may work for you as well.

The other option then are the 1050Ti's, the modern equivalent of the old 750Ti's.

Cheers.

. . Although probably lower in individual productivity than Tom was hoping for, a pair of them would probably come close to matching the output of one 1060. Not sure there is any benefit in output/power consumed though. For perspective my HP box only has a 240W PSU and is happily running my GTX1050ti, so his 400W plus PSU should cope easily with two of them. But my 1050ti is drawing about 60W at full crunch and my 1060s are only drawing about 90W also at full crunch. So I would expect he could probably run a brace of 1060s with his PSU if he has 2 suitable PCIe slots. That would give him some serious crunching power.

. . As a baseline my HP has a total power draw of about 110W to 120W with one 1050ti. My clunky old Pentium D with 2 x 1060s has a total draw of a little over 300W. So I feel his setup could support that at a pinch. But again, if he has enough PCIe connectors on his PSU maybe a single 1070 would draw less total power. But I still think 2 x 1060s might give better overall bang for your buck.

Yep.
My GTX 1070s generally sit at around 15-110W, and around 110-120W or so with Arecibo WUs.

Keep in mind that with the release and use of a more optimized application their power usage would increase significantly.
