PS PS. 1. Short for power supply and sometimes abbreviated as PSU, which is short for Power Supply Unit. A power supply is an internal hardware component that supplies components in a computer with power. The power supply converts a 110-115 or 220-230 volt alternating current (AC) into a steady low-voltage direct current (DC) usable by the computer and rated by the number of watts it generates.

- The PSU represented by the point on the PPF where an efficient economy operates (which is obtained by tangency with the highest individual or social indifference curve, not shown in the graph) presents the priorities or choices of the modeled agent, such as the choice of having more butter produced and fewer guns, or vice versa.

Rack unit A rack unit (abbreviated U or RU) is a unit of measure defined as 1.75 inches (44.45 mm). It is most frequently used as a measurement of the overall height of 19-inch and 23-inch rack frames, as well as the height of equipment that mounts in these frames, whereby the height of the frame or equipment is expressed as multiples of rack units.

How to Buy a Power Supply 1 It's possible for a 500W 'value' PSU to produce less power than a quality PSU sold at 350W. 2  Thus, 'upgrading' a PSU but selecting a low-end model, may actually be a downgrade! 3  Never open a power supply, in spite of information on the internet advising otherwise.

British thermal unit (Btu) A British thermal unit (Btu) is a standard unit of energy that is used in the United States and sometimes in the U.K. It represents the amount of thermal energy necessary to raise the temperature of one pound of pure liquid water by one degree Fahrenheit at the temperature at which water has its greatest density (39 degrees Fahrenheit). The Btu is a measure in the so-called English system of units (the foot-pound-second system). Other countries use the joule, the unit of energy in the International System of Units (SI). A Btu is equivalent to approximately 1055 joules (or 1055 watt-seconds).

PDU and UPS PDU and UPS. I have 6 PDUs connected from a power source dropping from the ceiling. They are proprietery connectors so I cannot do anything else. Right now, my small business enterprise UPS units, (7) are connected among these various PDUs. Now the ups's run 2-3 servers each. I have a new rack that comes with more PDUs.

- Modular Power Supplies. Corsair Modular power supplies have cables that can be attached to the power supply individually. Unlike more basic PSUs, which have permanently attached cables, modular power supplies allow you to use only the cables you need for your particular installation.

Should You Buy a Modular PSU? What is a modular power supply unit? In simple terms, it is a power supply where some or all of its cables and connectors are detachable; This is different from a regular power supply where all its cables are permanently fused to the unit.In the image below, you can see the difference between a modular and non modular PSU.y detaching unused power cables from a modular power supply, you will typically end up having three to four less cables within your computer case. That's at least 1.5 meters (5 feet) less cables snaking inside your case and hiding in your drive bays.

- The Scoville Heat Unit (SHU) is a subjective scale used for measuring the spicy heat of peppers (and other hot foods). It’s a function of capsaicin concentration, though it’s not as accurate as the actual measurement of the capsaicin content of a pepper because it’s assessed empirically by panels of testers. In ascending order, here’s how the hottest peppers in the world rank. (Fyi, we’ve blown right past the rather tame jalapeño.)

Salinity The 'unit' of PSU (denoting practical salinity unit) is sometimes added to PSS-78 measurements, however this is officially discouraged. In 2010 a new standard for the properties of seawater was introduced, the so-called thermodynamic equation of seawater 2010 (TEOS-10).he resulting 'Knudsen salinities' are expressed in units of parts per thousand (ppt or ‰). The use of electrical conductivity measurements to estimate the ionic content of seawater led to the development of the so-called practical salinity scale 1978 (PSS-78).

Colony-forming unit In microbiology, a colony-forming unit (CFU) is a unit used to estimate the number of viable bacteria or fungal cells in a sample.Viable is defined as the ability to multiply via binary fission under the controlled conditions.stimation of microbial numbers by CFU will, in most cases, undercount the number of living cells present in a sample for these reasons. This is because the counting of CFU assumes that every colony is separate and founded by a single viable microbial cell.

How does a Phasor Measurement Unit (PMU) work? A phasor measurement unit (PMU) or synchrophasor is a device which measures the electrical waves on an electricity grid, using a common time source for synchronization. A PMU can measure 50/60 Hz AC waveforms (voltages and currents) typically at a rate of 48 samples per cycle (2880 samples per second for 60Hz systems).

British thermal unit The British thermal unit (BTU or Btu) is a traditional unit of work equal to about 1055 joules. It is the amount of work needed to raise the temperature of one pound of water by one degree Fahrenheit (Physical analogue: one four-inch wooden kitchen match consumed completely generates approximately 1 BTU). BTU is the amount of heat required to raise the temperature of 1 avoirdupois pound of liquid water by 1 degree Fahrenheit at a constant pressure of one atmosphere. calorie, several definitions of the BTU exist, because the temperature response of water to heat energy is non-linear.
