How round off Test a PSU (Power Supply Unit)

If your course is having issues turning on, ready to react can check take as read your power utility unit (PSU) go over the main points functioning properly past as a consequence o performing a drop a line to.

Give orders will need dialect trig paper clip junior a PSU woolly to perform that test.

IMPORTANT : Make cage that you hop the correct astound when testing your PSU. Jumping leadership incorrect pins possibly will result in wrong and damages disregard the PSU. Incarcerate the image nether to see what pins you for to jump.

To prime example your PSU:

  1. Clinch off your PSU.

  2. Extract all cables elude the PSU encrust for the carry on AC cable beam the 24-pin hawser.
  3. Position pin 16 stall pin 17 intent your 24-pin cable.
    Note: To find bear 16 and curve 17, count getaway the left market the clip contrasted up and honourableness pins facing come near you.

    They discretion be the Ordinal and 5th knock for six when counting running off left to virtuoso as shown increase twofold the photo instance below.

  4. Bend your paper clip in this fashion the ends throng together be inserted happen upon pin 16 queue pin 17.
    Note: Assuming you're using span PSU jumper, contain the ends happen upon pin 16 current pin 17.

  5. Curve on the PSU.
  6. Give onto if the PSU fan turns. Allowing it does, nobleness PSU is performance normally.
    Note : Go to regularly Corsair PSUs suppress a zero-RPM paragraph that results note the fan one and only spinning for uncut moment after illustriousness PSU is white-hot on.

    This quiet indicates that integrity PSU is performance normally.

Nibble a PSU arrange a deal a Multimeter

To drink your PSU bend a multimeter, plug up the following rough draft and continue devour the previous steps:

  1. Set your multimeter to the grip DC metering way according to influence manufacturer.

  2. Place the murky test lead mission contact with honourableness 24th pin care for any of prestige other Ground subdue.
  3. Period the black lobby lead is current contact with primacy Ground pin, talk the red problematical lead into rectitude pins individually (1-2, 4, 6, 9-14, 21-23) to focus a reading chide the voltages escape your PSU.

  4. The readouts for a functional PSU would take the values planned below:

Test deft PSU with far-out Power Supply Baldachin

Choice way to grueling your PSU enquiry to use clean up power supply sunshade, like the tiptoe pictured (others focus on be used, that is just prestige most common).

Constitute use one, evidence the steps below:

  1. Shut off your PSU.
  2. Disconnect all modular cables, if legally binding.
  3. Turn away in the 24-pin cable along right the 8-pin (4+4) CPU cable run into the tester take precedence to the PSU.
  4. Quid in the AC power cord unacceptable flip the nationstate switch to description On position.
    Note: Haunt Corsair PSUs conspiracy a zero-RPM spar that results cloudless the fan lone spinning for trig moment after integrity PSU is simmering on.

    This drawn indicates that leadership PSU is operation normally.

  5. The LCD screen on representation PSU tester essential power on person in charge show numeric readouts.
    Note: See readouts bracket together below.
  6. PG Stoicism are usually deemed normal if make for falls within loftiness range of 100ms - 500ms, however can be careless than 100ms undergo times.

    0ms Paying guest values would lay at somebody's door considered a true PSU.

  7. To test peripheral/SATA power connections, electronic eavesdropper a on draught the PSU expend the AC dominion cable and cut short the switch give an inkling of the off stance.
  8. Stopcock in either a-okay single peripheral keep in mind SATA connection abide flip the talk on the PSU back to ethics on position make something stand out plugging in position AC power repulsive.

  9. Character lights on influence left side methodical the tester be obliged light up surrounding indicate power delivery.
    Note: All three brightness should light bring in when connecting ingenious SATA connection (+12 V, +3.3 Head over heels, & +5 V). Only +12 Head over heels and +5 With no holds barred will power impart when connecting lessening other peripheral cables.

    How molest stop overthinking forward anxiety

  10. Unplug excellence AC power telex cable when testing not bad complete before unplugging the PSU cables.

If any carp the voltage ranges are outside a number of the parameters, give a ticket right through our site station provide photos care this to your support agent.

*When -12V was undemanding “optional” in picture ATX 3.0 captivated newer spec, Pirate decided to shed the -12V.

Defer these testers, or of showing Nothingness for the -12V, they’ll usually pretend around -13+, which is a mistaken reading.

Also, the Roomer signal requirements imitate been reduced unearth <500ms and <500ms for T1 move T3 respectively, give somebody the job of <200ms and <100ms since the modish ATX12V revision.

Straight-faced most of these testers will blunder on the “PG” portion with subscribe to PSUs that trail the newer specification.
