Is 400w enough for a i3 4130 and a single 750ti? That's the kind of setup that will use under 100w running some games. Reaching the ideal efficiency range for a 400w unit isn't possible because the power draw it too low to be near 50% draw on it
I need some math here. Lets say pc use 100w running games and psu has a 80% efficiency. 100*(80/100)=125w. This means a psu with ~250w is the best option?

I'm not sure where the 250W comes from. Double 125W? If you wanted the PSU at half load, you'd want 200W capacity. (They're rated for output power, as you'd expect, not input power.)
The issue is nobody sells sub-300W power supplies of any quality at retail in most countries, especially the NA market. The main thing is that nobody is interested in buying them, and it doesn't even save much money at all for the manufacturer to spec things for that wattage and not say 400W+ if you're already using an ATX form factor.
And having a larger power supply with slightly lower efficiency in the region only loses you a couple watts anyway, no big deal.

Question:
I started to play bw again and i have non stop lag and lagy fealing when i play.. I watch on youtube game
To see how remember how BW looks i mean works and i see other players have flow of game.. They play normal.. I cant even make drones. Imposibe to play even sending units is hard.
I have 2 pc:
First is on win 7 and i open all ports and instal launcher and same shit again.
Secund pc is on win xp with only sc bw on it and launcher and still same shit.. Imposible to play.
What to do?!? Can someone conntact me?
Thank you.

It's a SFX PSU for a mITX build. I'll go for a 300w one most likely

I don't know if I ever posted this, but I thought some of you might find it interesting.
Out of curiosity, I bought a Kill A Watt the other week and have been running my PC through it. I have a 3770k somewhere in the >1.3V, <1.4V range (I really don't remember) and dual 780s, plus like 8 drives.
At 1440p doing the highest setting Bioshock benchmark run a few times my actual load (from the wall) was only about 350W.

This is probably why the blue people in the thread are skeptical of manufacturer claims that you need something like 650-700w power supplies for mid-range graphic cards.

We've all seen far more data than that, there are charts of actual recorded power consumption everywhere.
Measured power consumption GTX 750 Ti card
System in IDLE = 120 W
System Wattage with GPU in FULL Stress = 202W
Difference (GPU load) = 82W
Add average IDLE wattage ~10W
Subjective obtained GPU power consumption = ~92 Watts
^Solid data.
http://www.guru3d.com/articles_pages/nvidia_geforce_gtx_750_and_750_ti_review,5.html
People quote GPU specs, such as reference 780 saying 42a of 12v (504w) but it's almost completely arbitrary.
Before the NDA on 750/750ti listed, there was a guy on OCN with an i3 and a gtx750, playing a few games and literally showing a power meter saying under 100w drawn from the PSU. That was not full GPU and CPU load simultaneous (games usually max out a CPU core or GPU, rarely using the GPU and all CPU cores near 100% unless you specifically work to split load in that way with stuff like changing render resolution) and stock 750 is lower power consumption, but it's a good example.
As for 350w running bioshock benchmark with that setup.. I'm curious for cpu/gpu load. That just sounds like you're not utilizing hardware, i'd expect it to hit 600w or so with GPU's both at 100% and CPU highly loaded with the game and something like x264 (for background encoding or livestreaming)
..Also, just open cpu-z or bios. It's not very hard to check OC settings, and if you have not checked them, how do you know that your CPU hasn't been at 3ghz or 1.5vcore for months? I check every day and like triple-check after changing stuff, but i AM paranoid because some idiots decided to put input voltage (~1.9v typically) and vcore (~1.3v typically) right next to eachother

After a great deal of consternation*, I was pulling about 450W on Dishonored at 7960x1440 (bezel correction) max settings. I don't know what actual GPU load was -- it felt super smooth so probably wasn't maxed.
[Edit]
Was 50% load and about the same for power consumption
Metro 2034 managed to max out both at 99% usage and about 90-95% total power consumption. Don't think I went over 650W, but came reasonably close.
+ Show Spoiler +*I guess NV Surround realllllllly doesn't like when you cheat and have a 5th monitor on the mobo port. Corrupted the drivers I guess because it BSODed during the switchover (from individual to spanned) and had to be reinstalled. Also Bioshock benchmark wouldn't span to a second monitor and wouldn't send video to the right monitor (but the left and middle was fine). What an effort.

Is it bad to run a low-consumption set up on an overkill PSU? Imagine a capstone powering a 750 ti + i3, is it really bad if the capstone isn't near the 50% load? It should be fine imo..

It's not bad, just inefficient. My PSU is (according to this number anyway, it's somewhere close..) ~88-93-88% efficient at 20-50-100% load. A lot of PSU's cliff in efficiency near or below those lower load levels though.
You have to remember though that idle power can be really low, like in the range of ~30-40 watts entire system for a haswell dual core and one of the little maxwell GPU's. At that point i guess it doesn't really matter how efficient you are, but it can be bad to buy a 1200w PSU just for the sake of having a 1200w PSU when your parts use 400w at load and under 100w at idle

Yeah OK, that makes sense. For sure, it's silly to buy 1200W overkill. I don't think it's even worth having a system that gobbles up that much power.

Some people disagree, also when pushing OC's silly hard on water with a system like 4x 290 and 1x haswell-e 8-core, power usage can be approaching 2kw (i've seen a reported >500w on a single gk110 on water)
|
The PSUs that are overkill can still be pretty efficient at low power consumption. It does not have to be exactly 50% for best efficiency. That area with close to best efficiency can be looking like some sort of plateau if you draw a graph of the efficiency at different loads.
Like Myrmidon said, you just can't find great PSUs at something like 250W. Then when you look at what 500W PSUs there are, you can find something with super great efficiency, and it will always beat a crappy smaller PSU.

If the PCs are in the same game, it will always lag due to NAT being awful. Otherwise, you need to do the following:
Use chaos launcher or some other method to set unique game data ports for each PC (eg PC1 = port 6112, PC2 = port 6113)
Remove all port forwarding (you only need to forward one port, not all of them),
Forward UDP port 6112 to PC1
Forward UDP port 6113 to PC2
This should let both PCs be able to play in separate games.

That's expensive though, it needs two gaming systems and like a $100 capture card so instead of say $400 for a new console or a comparable PC, you're looking at a cost of ~$400+~$400+~$100 if you don't already have that hardware.
Why do I need two gaming systems? That sounds kinda odd. I have the PC to stream it for sure, but that sounds odd that I need two.

Because you need one console and one PC

I have a Lenovo G505s Laptop, and all of a sudden I can't use the integrated mic when I plug in my earbud. Why do I want to plug in my earbud? Because otherwise my voice is very low, despite turning everything up. My audio options says that "Digital Display Audio - (AMD High Definition Audio Device) Not Connected". I reinstalled the driver, I went back in time with Windows but the problem remains. When I try to enter to my microphone properties, it says "your current default speech engine does not support this action at this time". I bought a headset, but the laptop has 1 place where I can plug it, while the headset has two.
Edit2: aaaa, actually mind it, it doesn'T work, I thought I'm editing another post... :D

OOOH. I thought you were saying two PS3s. I was like wtf??
Question now that I see that you are here... I'm looking at this one amazon:
http://www.amazon.com/Elgato-Capture-PlayStation-Definition-Recorder/dp/B00840353W/ref=cm_cr_pr_product_top
I know that is more high end, but this is what you are talking about, correct?

Something like that yea, i've never heard of that one in particular. If whatever you're using has hardware h264 encoding, try to make sure that you can get video passed through losslessly to PC for encoding with x264 using OBS if possible, because the hardware h264 encoders are nowhere near as efficient (they need more bitrate for same quality)

When I plug in headphones into my new windows 8 laptop, no sound comes out. When I plug them in the popup saying that an audio device has been detected appears, but the headphones do not appear on the list of sound devices. I've tried updating/reinstalling the realtek drivers and it still doesnt work. Any solutions?
edit: nvm solved, apparently taking out the battery and holding the power button for 30 seconds does smth to fix it (??)
