- interiot, on 10/12/2007, -1/+8Everything about >ATX< power supplies. While it's a good article, it doesn't cover buck-boost power supplies or ensuring your control loop is stable.
- repruhsent, on 10/12/2007, -2/+8Thank you for posting this - I always wondered why my box was big and black.
- ochito, on 10/12/2007, -0/+5All black wires are ground, so any of them will do
- Peptis, on 10/12/2007, -1/+6Big black boxes are essential if you ever go down. For disaster recovery, of course :p
- ronjohnson, on 10/12/2007, -0/+4Tom Hardware had a great review of 21 power supplies titled
Inadequate and Deceptive Product Labeling: Comparison of 21 Power Supplies

http://www.tomshardware.com/2004/01/22/getting_the_right_power/ - ThankTheCheese, on 10/12/2007, -3/+7I already knew everything I wanted to know about power supplies...nothing ;)
- redneckblues, on 10/12/2007, -2/+6Don't wanna throw a hotdog down a hallway, now do we?
- r3zonance, on 10/12/2007, -4/+8Well, I didn't want to know anything about power supplies.
- Phaid, on 10/12/2007, -0/+3Great article. Even though it could probably elaborate more in some areas, it points out the major things to look for.
"we still see people swap out every part except their power supply in an effort to troubleshoot a mysterious problem."
Most definitely true. It's so sad to read hardware forums and see people complain of lockups on PCs they've just built, and watch them go through tons of driver revisions and reinstalls and all sorts of gymnastics, and they won't even list the PSU they're using in their specs. And then when they finally do, they're trying to use a totally underpowered PSU for the hardware they've put together.
If more people read the current specs on their PSUs they would know to avoid horrors like the Antec "green power" power supplies, which are only "green" to the extent that they supply less current than they need to, and so basically can't handle configurations that most other similarly rated PSUs can. - dralezero, on 10/12/2007, -0/+3It says to connect the green and black wire but there is like 7 black wires in that picture. Is it always that 3rd connection from the green or what. How do you know?
- inactive, on 10/12/2007, -2/+4Ling Ling knows the safest place to be in an airplane crash is inside the black box!
I'm digging this story just for the hysterical leader line. - Abenzio, on 10/12/2007, -0/+2Good read!
- r3zonance, on 10/12/2007, -1/+3Kind of "fizzy" on the tongue. :P~
- madmanguruman, on 10/12/2007, -0/+2The 240VA limitation has less to do with Intel's wishes, as the article implies, but because the total 12V energy would be classified as "hazardous energy" by various safety agencies (UL, etc.) which would greatly complicate things (such as limiting sale or installation of the supplies to licensed personnel, etc.) ...
- Ryaaan, on 10/12/2007, -0/+2Keep high CFM fans away from the power supply. I've seen examples of fans mounted just below the power supply's 120MM fan that were of a higher CFM then the power supply's fan. The resulting venturi effect actually created a vacuum in the power supply housing!
I have actually seen this happen. Vacuum effects overtake a case and components start to fail. All because of poor fan placement and unbalanced CFM. Good article. Really enjoyed it. - zcreem, on 10/12/2007, -1/+3Females have sockets, not plugs.
If you don't believe me take a look. - doolittle, on 10/12/2007, -0/+2LoL - luckily there is only one green for ps_on and any of the black grounds *should* work to fire it up. I have always used the adjcent one for convenience...
A more detailed guide to powering on AT and ATX PSUs standalone:
http://www.directron.com/2powersupplies.html - silentdud, on 10/12/2007, -1/+3I actually read this entire article.
- DWatch, on 10/12/2007, -0/+2So are most of the power supplies sitting on store shelves right now. Online shops might have more updated models, but a lot of stock on shelves is years old... thus the articles are still valid today.
- calpaully, on 10/12/2007, -0/+1The guy in the article referred to "watts, amps, [and] volts" as "buzzwords". I'm no electrical engineer, but I'm pretty sure those terms are historically documented and here to stay! Once they start rating power supplies in Watts 2.0, you can start calling it a buzzword.

True all those are commonly used terms by Electrical engineers
AMPS= Current
Volts= Voltage also known as Electrom Magnetic Force
Watts= Power = Current * Voltage
Anyways i thought the article was pretty good but i disagree with the guy complaining that his voltmeter is precise only up to 1 percent, which is actually fine because powersupplies are rated good as long as voltages are within +-5 percent. - reefinyateef, on 10/12/2007, -0/+1This is a great article! I recently had a computer problem where I swapped out everything, cleared CMOS, blah blah blah, and the problem ended up being the power supply.
- kualla, on 10/12/2007, -0/+1thats first thing I thought when I opened the site... at least have a printer friendly version even if text only!!!
- wthulhu, on 08/29/2009, -1/+2I've often wondered what they tasted like...
- TechScribe, on 10/12/2007, -0/+1I'd like a printer-frienlkdy or PDF version of the article.
- EiderDuck, on 10/12/2007, -0/+1Agreed. That article was way too many small pages.
- bradproctor, on 10/12/2007, -0/+1Been using the paperclip trick for years.....Paperclips, a must have in any toolkit!
Hint: If you notice your computer will not cut on at all try disconnecting the ATX connector (if you have a 4-pin 12 volt connector disconnect that also) from the mobo and perform the amazing paperclip trick. Have seen many power supplies considered dead until the paperclip revives them. - Jozer99, on 10/12/2007, -0/+1Good article, but the number of adds was actually quite impressive. It makes engadget look like Google's homepage.
- magicaltrevor, on 10/12/2007, -1/+1Digg effect :(
- im12env, on 10/12/2007, -3/+3Yeh they have a real Zap to them... Quite shocking realy....
- Jayeugene, on 10/12/2007, -0/+0@st3ady:
Ive had that happen to a cheap power supply before, i think you will be fine since there is voltage regulators in most power supplies that don't let a shock current get through to the motherboard. What you should do is take the power supply out of the computer and look and at it and smell for burning plastic. it would probably be a good idea to check your computer case for broken shard of metal at all behind the mobo and then replace the power supply with a good quality one. - phatvolvo, on 10/12/2007, -1/+1trial and error?
- zafw05, on 10/12/2007, -2/+1Article was a goood review about a PSU. While it's an article to just simply understand the basics, there is still much more that needs to be covered or at least mentioned.
- inactive, on 10/12/2007, -2/+1those articles are over 2 and a half years old
- MichelKuik, on 10/12/2007, -1/+0Why's this in Design?
- st3ady, on 10/12/2007, -2/+0last night there was a big thunderstorm here and during the night the power went out. When I woke up the power was back on, and my computer was off. I hit the power button and nothing happened. I hit it again, nothing. Then I hit it again and about 3 seconds later I saw a small circular flash behind the tower near where the Power Supply is and a loud pop. I am scared :( Do you think all I need to do is replace the power supply and everything will be fine? Or do you think the whole computer is fried and all my files on my hard drives are gone forever? :( :( :(
- morgdx, on 10/12/2007, -2/+0I'm commenting on an article about power supplies. I need to get out more.
- dralezero, on 10/12/2007, -4/+1@phatvolvo
lol - intricate, on 10/12/2007, -8/+4My female plug is very big.
- ochito, on 10/12/2007, -5/+1@Peptis
You DO of course know that big black boxes for when you go down are actually orange, right? - DangerMouse9, on 10/12/2007, -7/+1repruhsent: "Thank you for posting this - I always wondered why my box was big and black."
Maybe because you're a big, black woman.
