Xbox 360 4GB Console Is Good Console With The Good Price
the revolutionary design is incredible. the design, size, just everything is great. For all people that say "its as hot if not hotter as opposed to regular 360" Well DUH it is on a single perish. That heat sink might heat up with exactly the same amount of heat because the old 360..just over a single die instead involving two. BUT it still owns cooler even tho it appears hot. Unless you do a true heat test you can't say it really may run hotter...because no. It almost runs 10c cooler sometimes.
New touch design MY SPOUSE AND I of Xbox 360 4GB Console do like (even the small beeps it gives people: D ) I really like how they put the fan to the side making air can be found in from the top and out from the side, way better design (you do not have to worry about it being against the wall anymore)
I such as the 4gig better because its matte, I had a 250gig in addition to sold it because used to do not enjoy the dust, prints, etc it drawn. I do believe of which spending $40 more for just a Xbox 360 4GB and buying a 250gig HDD separate is the way to go.
Of course no Blu-Ray even tho that may be great since the fact that reason I own some sort of PS3, but thats Sony not necessarily MS. Its not gonna happen although we wish it would.
I think the controller that is included with the console is really more 'better' (bad syntax on purpose) I just like the D-Pad it feels to me that they have change it some. And i favor how the battery features actually fit well inside the controller now and the newest Chrome guide button.
built-in wifi is a absolutely no duh, why didn't they do that at the start...But is great as well as its N band.
only negatives..the power supply now features a fan in it, it's louder than the console itself in the event the game you are playing is installed for the hard drive. BUT that's not a bad thing really as the PSU needs a fine fan. And that is definitely nit pic (my LAPTOP and PS3 are as loud if not louder)
Great xbox console wish they might have started out with this good of a console from your start.
Can a computer PSU kill you?
If you discharge the capacitor on a computer PSU just after you unplug it and it gets you, can it kill you? If so can you explain how and provide some math behind it. Thankyou
There are lots of discussions on this in one form or another.
If you discharge the capacitor (intentionally / relatively safely) just after you unplug it, then it won't be a serious danger. Maybe some ghost charges left, but nothing more than a few sparks.
If you discharge the capacitor (unknowingly / with your body) just after you unplug it, it probably won't kill you - but it can cause burns, muscle spasm, other effects. Of course - there are always rare circumstances... did you get a high-wattage PSU for gaming? did any psu come with true-rated parts, or anything old cheap capacitor that happened to work that day (possibly some faulty or larger-than-expected caps)?
Does the victim have a pacemaker? metal rods or screws inside to help conductivity? covered in salt water or battery acid, (or any other electrolyte?)
Basically, a capacitor circuit can "change the rules" for voltage and current. Just because your input is 110v/15A or 220V/10A, and output is 3.3v, 5v. 12v DC up to 3A... there could be some places where a capacitor stores a whole lot of charge. If you short the leads - and go around the output circuits, resistances and chokes, control circuits (pretty difficult to do accidentally) - then you can have a very fast discharge of the energy stored in that component.
I've heard estimates that human body resistance is as low as 300 ohms. Maybe that was a mistake or mis-print. Personally, I've never seen anything less than 800 Kohms. - I usually read 'me' at around 1.4MOhms.. (read the DarwinAwards in the references below - they say 500K to 2Mohms). But - like the guy in that DarwinAward incident, if you happen to be bleeding, or the leads make contact with your bloodstream - that resistance is pretty low.
Under this RARE circumstance, sure, that capacitor might kill you.
Generally - no. You need between 70-100ma to kill someone. With the body's resistance at estimated low of 500 kOhms, you'd need a capacitor charged to around 3.5 - 5.0 kV potential.
(V = IR, where I= 70 X 10e-3 and R= 500e3, V=3500 or 3.5 e3) - more for higher values of R or I)
check the math, I frequently go nuts for no good reason
to find a single component in your average 500W or less PSU that needs to charge to 3.5kV is highly unlikely. Even more unlikely is that Dell, or Apple, or Lenovo would actually buy a component capable of storing this much energy for a DC application, then sell it as part of a sub-$1000 USD machine.
I'm not sure of all the math to convert that back to coulombs and farads.. but I'm pretty sure you stand about as much chance as getting hit by two meteors on the same day.
I won't say it can never happen. Some idiot out there will electrocute himself just to prove we are wrong here... but it is very unlikely to happen by accident.
MORE LIKELY - injury, burns, chemical burns, injured by exploding parts of faulty capacitor that suddenly gets heated up in discharge. - Heck, I've done most of these things to myself.
I've listed just a few of the more sensible articles online about this. Some aren't as good as others - but there are some real nuts on the internet .
