Would a 195 watt Pico PSU work with an i5 6500 + GTX 1060?

[Elf_Knight]

In the summer I want to do a new small form factor build and make it as power efficient as possible for 1080p. My current set up is an i5 4690k, 8gb ddr3 ram, and a gtx 970 with a 525 crucial ssd, 1tb wd blue hdd, 500 watt evga psu, corsair h100i v2, fractal design nano s and Windows 10 free upgrade from windows 8.

However I want to sell my CPU, Ram, and GPU so I can go more power efficient and use a Pico PSU along with a 195 watt laptop charger thing I found on Amazon that works with the fanless PSU. I will make/mod a custom case so that it is literally just the motherboard, gpu, ram, and an ssd. I will also possibly have an M.2 ssd and I will ditch my hard drive in favour of the m.2 ssd and 525gb ssd. This is to make it as silent as possible without any moving parts. The GTX 1060 will be the Zotac mini model so it is perfect for this build since it is very small and not very hot. Also will be pretty quiet as well.

For the case I am going to make/mod a so it will basically be like the Asrock Desk Mini 110. I will get the HDPlex 300 watt Pico PSU and use it with this laptop charger from Amazon: LEICKE 192W Power Supply PSU Charger.

Specs for the new build:

i5 6500,
16gb ddr4 ram HyperX,
GTX 1060 Zotac 6gb
M.2 525gb Crucial SSD,
525 SATA SSD Crucial
CPU cooler will either be the stock Intel Cooler or the Noctua NHL9i
PSU I have already stated.

I have seen a lot of YouTube videos such as from the channels of Not From Concentrate or YetAnotherTechChannel where they have used these Pico PSU's and have even powered an i7 and a gtx 1070.

Obviously I will not be doing any overclocking. I will be using stock settings and will be using passive exhaust since everything has its own independent cooling and is quite temperature efficient already. I was tempted to get a low profile GTX 1050Ti but I need more FPS since I play a lot of MMO's. I will only be gaming at 1080p possibly light 1440p gaming which the 1060 is perfect for.

So my question is do you have any feedback on this build? Are there any custom cases big enough for this purpose? I just want to install everything on the motherboard and have 1 or 2 SATA SSDs along with my internal M.2 SSD.

Will the 195 Watt Pico PSU be enough to power all of this with the HDPlex 300? Are there any other chargers that are more powerful to use with the HDPlex 300?

Many thanks in advance! Sorry for the long post.

P.S. I have not got any of these parts yet but I will save up for them in the summer so any advice will be greatly appreciated!

why do you want to get more efficient?
If it is for the cost then you'll spend more than you'd save over maybe 5+years.
If it is because you are in a highly power constrained scenario then I think it's too tight peronsally.

It is about the cost and power efficiency. However it is also about size and form factor. I want to cut down on size of the case as much as possible and make it as portable as possible. I already have the Fractal Design Core 500 from a former build but didn't like the way the lid closed cause it was a real pain so I might mod that and make a new lid. Basically I wanted to save room and just have the bare basics of the gaming PC and have the PSU outside like you would with a laptop. Would that PSU be fine for an i5 6500 and a GTX 1050Ti? Are there any higher wattage laptop chargers for the 1060?

From an efficiency point of view I'm not sure you are gaining anything, for a normal PSU you want to be 50-75% loaded for efficiency reasons. and you might hit 90% efficient, I don't see that a power brick + pico PSU would be more efficient, especially as you are going to be running them at the top end of their range. The generate heat so they are not 100% efficient.

Lets be generous and say that combined they are 95% and that this is 5% better than a normal PSU.

Lets say that you are pulling 150W for 5 hours a day 365 days a year. So 5% of 150 = 7.5W less that you are paying for, which means you need to be running at that load for 133 hours before you save a unit of electricity, that'll save you maybe £0.12, or $0.12, so over a year you'll save around 14 units, so that's $1.68 per year saving IF the PSU is more efficient. How much is this going to cost you do? $100? that's a 60 year payback.

If you are thinking of overall 'greenness' you're buying new stuff, that had to be made etc.

So if you are going to spend more for pico with the thought of it saving you something, it won't, if you want to do it for other reasons alone then I still think it is too tight.

I also think passive exhaust on the pico PSU will be a problem, the voltage converters that fit into the 24pin connector will give off some heat, with no forced air movement they could overheat.

Have you considered a bit fenix prodigy? or something that needs a SFF PSU?

The main thing would be to save space on the inside of the case and cut down on cable clutter. Pico PSU's are a lot more space efficient rather than power efficient. With the right specs it is possible but I probably won't do it. Would an Intel Pentium/GTX 1050Ti be okay? They work on any PSU from what I heard. Ah well I will probably look into getting an SFX PSU. Thanks for the advice!
