Will this power supply fit in this case?: http://www.newegg.com/Product/Product.aspx?Item=N82E16811553011 (COUGAR Mini Tower Case)

http://www.youtube.com/watch?v=FrA3GfUJ8pM 2:09 rear PSU base view 2:38 front PSU base view 3:16 back PSU base view 3:25 front PSU base view with PSU mounted

The reason I ask is because I had a 450w modular power supply (http://www.newegg.com/Product/Product.aspx?Item=N82E16817151124) planned to buy but I've found out it is big wattage for my current components wattage. I place parts in pcpartpicker and I get maximum wattage of surprisingly low 124w, and power supply is 450w, so that means that in idle or normal surf will be below 20% of power supply (it is 90w) and some videos talking about power supply says that going below 20% can reduce significantly efficiency, so if 20% is 90 and total wattage getting is 50-60 then it may drop even to 70% or more or less efficiency.

The reason of getting this one is because it's the only one below 400w that is modular (semi and full doesn't matter if it's just motherboard and CPU connector hocked, as it will obviously be used, some do hock unecessary SATA cables or such, but that's not the case with the 450w psu), and a very well bonus, it is gold rated, same as the 450w one.

Thanks for reply and recommendation, I saw it but the problem is: it's not modular. It might make a total mess because I only need few cables, I will only be using 1 HDD, 4 x SATA so 3 SATA lying around, wont use dedicated card so 1 x 6pin PCI-E lying around, dont use floppy, or if use, with adapter (fan) so 1 x Floppy lying around, dont know about 3 x Peripheral but, with 5 cables I think it's a total mess as this is small Mini case and it has no holes for cable management, and I dont think the 5.25 space will store it all, or if do, with mess :( with small space as shown in video I think it might even block other cables and stuff lol

Well the PSU that the OP is linking to will not work in that case. The case uses a standard ATX.

Really the Seasonic you linked should work just fine for you. It is not so over powered to cause any problems and would give you some room to grow if you needed later on.

Then get the Seasonic G-Series 450W (SSR-450RM) that you linked to in your original post. The PSU will not be putting out 450 Watts continuously since the system will not be drawing that much (i.e. most likely less than 100 Watts).

If we use 100 Watts as the system power draw you should be able to measure a power consumption of 112 Watts at the PSU's AC power plug. The SSR-450RM conversion efficiency is around 88.9% at a 100 Watt system power draw so that's where the extra 12 Watts shows up at the power plug and is noticed as the warmth of the PSU's shell.

I said that in description lol, I know it's not 450w continously, but as 90w is 20%, reviews have said that if it's below that (like in idle) it may drop efficiency significantly, and I dont want to be constantly getting more watts just because I dont want efficiency to drop less than 80% lol :/ the reason I say it's because 124w is maximum, so in idle it will be like 20w and in web search like 50-60w, I think it may be lower but a measurement.

Thanks for the reply. It's not that it's overpowered, it is that it's too low watts when in idle or maybe searching web, as 20% is 90w and reviews have said that if it drops below 20% it may drop efficiency a lot, like 70%.

There actually is a adapter bracket which can be used to fit like ATX power supplies, but I thought you guys knew about it. The problem is that I dont know what is that "adapter bracket" as it mentioned in the reviews.

Thanks for the recommendation, although the price is high :/ I seached in pcpartpicker and the ones modular found at 400w are platinum and expensive, and the most smaller wattage of standard size is a 430w one but many reviews says it explode, not only in the moment but can also happens hours, days or even weeks later :O in 450w other happens a lot more rarely, like to 2-4 persons happened when like 5-10+ in 430w one.

What's weird is that it gets no compatibility errors with it, and in description it says ATX Power Supply, and I cant get compatibility to the 300w one, and that is the one that the person reviewed that didn't fit and needed for a adapter bracket, and the thing is that they are both same size. Compatibility could be by area volts, like 3.3v, 12v, etc. and not size. The solution would be to get the adapter bracket which don't know what is, get the 450w one which can drop efficiency significantly but deal with it so have to leave it drop, get the 400w expensive which won't make much difference as 400w 20% is 80w, and 450w is 90w, and last, get more wattage. I want to know how much efficiency I will get with 450w at 10% load which is 45w :/

What I forgot is the case fans (x2, one with blue LED) and usb ports when connected (I usually connect like 2 usb cables, 1 usb for headset and 1 for flash drive). How many watts for 1 usb cable? Getting those connected will get enough wattage for 20% load? I think so but the problem would be when idle.

Ah, even the 350w 20% is 70w, so in idle it will go below 20% anyways, so that means I will have to deal with getting less than 20% load, so ignoring the efficiency drop, right? will 70% efficiency be a problem when the computer is idle? (30w max example, I've read reviews of i3-4130T idle at about 8w so yeah)
