I can not stress enough the importance of buying a quality PSU, because it is such a hard thing to reconize when it is causing trouble. So exspect to spend around $100 on a quality power rig PSU.

A few months ago one of the HW sites (toms? anandtech?) built a test rig and load tested several brands and many failed before they hit thier advertised rating, one even caught fire before it got to it's listed rating. Antec and one other not common around here made it. One of the brands even got past it's rated level before calmly shutting down, to start back up fine when they tried a few minutes later.

I unplugged it and noticed that the connector was hot as hell, and that the plastic around the 5V contacts had been charred from the heat. Apparently, there was some contamination (dust, finger oil or whatever) on the connector that caused an increased contact resistance, which in turn produced enough heat to melt the plastic and obviously produced enough of a voltage drop to crash the PC.

Apart from that, passively cooled PSUs are quite expensive and the lifetime estimates are dubious.

Coupled with perhabs a silent case fan and a silent CPU HSF a mid-range system doesn't have to be very loud. Graphics card cooling sucks, though. You can use 8 and 10 cm fans on mostly everything - case fans can even be 12 cm - but graphics cards and mainboard coolers often are of the 4 to 6 cm variety, which has to spin a lot faster to get equal airflow and as such is very loud.
      Note that although Shuttle PCs often are really loud, their way of cooling is great: the whole system is cooled by one relatively large (8 cm?) fan, including the CPU which has a heat pipe attached to it transferring the heat to the fan.

Now add a load that (extreme example) feeds a switching power supply (CPU regulator for example) that has some failed input filtering. The chopped (by the regulator in switch mode) current has no filtering until it reaches the filtering in the output of the power supply. So in this example, the chopped current draw would have a matching magnetic field (current and magnetic field are directly related). This is the source of the radiated EMI off the DC power leads.

  44. I have one of these... by Cyno01 · · Score: 2, Informative

    Recieved it from FrozenCPU last week, its extremly quiet, and probably cut the noise of my PC in half. Also, the chrome and silver/black connectors look very clean. You can get a 500w power supply for a lot less, but it wont look this nice and probably doesn't have the performance (nobody ever reviews cheap PSUs). Its been running an XP3200+, 2 vid cards, 3 SATA hard drives, 2 optical drives and 3 fans without any hickups. Another review here.

  45. Neopower is QUIET!! by MadRocketScientist · · Score: 1

    Personal experience follows, not a paid solicitation ;) I just bought one in my latest upgrade system, and I'm totally amazed at how quiet it is. I can barely tell my computer is on! The fan is not on the back, it's on the bottom of the PSU, allowing Antec to use a larger fan (meaning it can move more air at lower RPM = quieter operation). I guess the modular connectors are an ok idea, but saved me no space as I needed to connect all of them anyway [4xhdd, 2x(DV-C)D]

      I concur, just put one of these in over the weekend and love it. The reviews mentioned noise levels climbing as fan speed was increased (duh) but it's seriously quiet. 120mm fans in PSUs are well overdue as a standard and you notice the difference immediately, the only trick is encouraging your MB that the fan is MEANT to be running at only 1440rpm :)

    Whenever I find I have 'too many cables' somewhere in my computer, I use it as justification to buy something new to put in the case.

  48. Power Supply: This isn't the first of its kind by Colonel62359 · · Score: 1

    Has anyone here not heard of the PC Power and Cooling Turbo-Cool 510ATX? This is a supply that reaches 500 watts at an ambient temperature of 40 degrees Celsius (that's about 110 Fahrenheit) rather than the typical 20 celsius. This seems to be a forgotten unit, when, IMO, it was the first, not this one. It appears that people don't seem to know anything about that other unit - it peaks at 600 watts, and you would have to have your system in a freezer to get a temperature that would allow such a peak.
