Help with picking a low power PC.
« on: October 05, 2015, 09:41:14 am »
I am looking at this device http://www.cclonline.com/product/185758/GB-BXA8G-8890/Barebone-PCs/Gigabyte-BRIX-Gaming-Ultra-Compact-PC-Kit/BRB0409/ for a low powered PC.
But I am unable to work out how much it will cost per year on power.
We pay 0.11p per kW/h but I am unable to work out what it will cost me, the device uses 135W I believe.

Many Thanks

What do you want to do with it? Does it need to run 24/7? A laptop with a low power CPU and graphics card may be a good choice.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

0.135 * 8760 (hours in a year) * 0.11 = 130.086

However, I doubt you'll run it 24/7/365, and even if you did it wouldn't be at full load. Let's pick a more reasonable 80W or so for say, four hours a day, and that's probably excessive (at least on consumption..).

0.08 * 1460 * 0.11 = 12.848

So it will cost £12 if I am reading your method correctly?

If it pulls 80W under gaming load and you use it like that 4 hours per day.. yes.

Whether that's what it will actually pull, and how much you'll use it..

There is a lot of guesswork here. But it's going to cost less than I pay every month for internet.

right, well with your method on 500w it costs £80 p/y to run, but is it worth it lol

I wouldn't get too hung up on just what the 'PC' uses. You have to look at all the other peripherals and devices you are using while you're at your PC. My dual monitors (29" + 24", with brightness set to about 15%), modem/router, 8port ethernet switch and two 20Watt desk lamps account for over 150Watts.

If you really want to save power, you need to look toward a laptop. And sit in the dark.

I would advise against AMD processors and graphics if you care about power consumption and disssipation.
Get something with an Intel and, if neededn an nVidia graphics card. nVidia has released the GTX 750 some time ago, and for $120 and 60W it matches the current consoles in quality and frame rates.

 It's still not up to the expectations of the current PC gamer market but for the p rice and power, it's pretty good. The GTX 950 uses 90W and should be quite good for gaming.

I made this list for you. Building PCs is easy. If you have any questions, just tell me. It's a compact case, a nice system and has lots of room for hard drive expansion. Has built in wifi, a surround sound card and takes 150W, using an efficient power supply. You could downsize he power supply I think. The best thing is that it's upgradable. You can save $60 if you go for the dual core Pentium G3258 gamers like it 'cause it's $60 and can be overclocked like crazy. The downside is that some games are becoming optimized for quad cores (or hyperthreaded dual cores), although this is happening too slowly. Two games refuse to run on dual cores but there are patches out there to fix that.

Not WTF. On a PC you have to rely on drivers, latest videocards, dual/quad cores (see above), etc. On a console you just pop the disc in and play. No dissappointments with unsupported hardware etc. I have seen it with my kids. Sometimes my wife would buy PC games for them but only very few worked for various reasons (needing administrator privileges, new/different directX drivers, etc). Since then the rule is to play games on a console. Nowadays they play several browser based games and steam seems to work OK as well.

Some people really seem to have difficulty using computers.

I buy a game. I install it. I play it. No mucking around. And I get to use real controls.

two 20Watt desk lamps
Perhaps you should fit those with LEDs to save more power.

I remember a time when PC games were difficult to get running, I think it was called the nineties. Funny thing, best I remember personal computers in general had a tendency to be finicky, pain in the ass things back then.

Low power = low spec + low usage.
A low power PC is good at games in 640x480 /256colors, for high spec games in 1080p you need a high power PC

But I am unable to work out how much it will cost per year on power.
We pay 0.11p per kW/h but I am unable to work out what it will cost me, the device uses 135W I believe.
First measure and read used energy for 1hr gaming, multiply with gaming hours/year.

While we are on the subject of  power supplies for computers, a 1200W PSU isn't consuming 1200 watts constantly even though the computer not using the power right?

right. Apart from the efficiency(%) vs load(%) graph (not a single number) every PSU 300W, 2400W consumes the same, given the PC does the same task.

so it's important to look at your personal nominal use, choose a PSU that's higher than max, but has its best efficiency at nominal

Not that it's a bad lifestyle, if done responsibly.


On the power supply question, get a power supply that has at least EPA ratings. It guarantees certain efficiency at certain loads and power factor. The minimum certification is 80% efficiency. These power supplies tend to be built MUCH MUCH better than the generic crap you find in the PC market.

Will WoW run on a NUC with i7-5557U w/integrated GPU? That is a low power solution? If so, go get one.

I use the i5-4250U NUC to serve as a NAS and compiling platform, and it served me for over a year, and is currently running well. Easily saturates GbE bandwidth with AES encrypted file sharing.

Rock solid reliability and stability. Till now, it only unexpectedly shut down for 3 times, both due to mains power loss or severe fluctuation.

Why not have a high-performance games machine for playing games and a regular low power PC/laptop for less demanding applications? I assume you'd spend the bulk of your computer time with the latter.

I just got a Raspberry Pi 2 and I'm impressed with what under 5W of computing power gets you (not that impressed with the on-board audio though). Not saying go to that extreme, but a capable laptop will do fine with a few 10s of watts.

Even the Iris Pro graphics are a bit of a stretch for gaming, they are widely outpowered by even a 60W GTX 750. I don't know about WoW, though, if it's light enough, well, it could run fine.

That's not a bad solution. I'd recommend an HP Stream 11 for a laptop. It's got like a 5W SoC, x64 Atom processor. A Chromebook minus Chrome OS.

I still like the idea of a Mini ITX gaming computer, though. I've toyed with the idea of building one.

Having personally used the HP Stream 11, it's very slow and really doesn't have the power to run Windows.  :scared:
