Small efficient PSU for mobo and 240V plug questions

So I have a HP 750W server psu powering a few gpus. Is there an efficient low watt psu that I could use to power just the motherboard? I have bigger 650w psus, but those wont be near their peak efficiency with such low wattage. Second question. Since the server psu can handle 240v is there any issue with cutting off the nema 5-15 power plug and putting on a 6-15? I'm running it off my solar setup, so it helps to have the load balanced and i've heard the psu is a bit more efficient?
 
Some people use pico PSUs for this purpose (low power output though). I just decided to stop using server PSUs altogether since it's typically close to $100 for a 1200W PSU and break-out board and I usually still need an ATX PSU to go with it a lot of times (or an even more expensive breakout board). I would typically load both PSUs with some GPUs each to keep them around 50% load. The 650-850W ATX PSU would typically power a couple GPUs and the CPU and the rest would go on the server PSU. Just make sure the same PSU powers both the riser and the GPU as a pair or you can damage your GPUs.

Thanks. I saw that breakout board with the atx plug on it. They sure are proud of it. The pico psu looks interesting. I may give one of those a try later, but probably better to stick with what I have. Not like i'd ever recoup the cost in electricity savings.
