Power Supply Test Result Confirmation

[jimmy.goossens.be]

Hello everyone,

I've ran a PSU test and would like to know whether the PSU is faulty or not.

+5V = 5.2
+12V1 = 12.2
+3.3V = 3.4
-12V = 12.1
+12V2 = 12.2
5VSB = 5.2
PG = 380ms

Thats not proper psu test, proper psu test should be under load, under 100% load or 750W (DC) should not be under 12V.Without load its normal that its 200mV above stock voltage or nominal.

Thank you for your reply Robert.

Does this mean the PSU testing device I bought is useless?
Because the testing device offers no options of connecting the cables to my motherboard after connecting them to the testing device,
because of this, I cannot think of a way to produce a 'heavy load'/'full load' test.

Yeah that might be problem, but you can connect traditional light bulb with filament (like in car front lights) , lets say 120W and you connect them on 3V, 5V and 12V and test the drop. Thats how i would do, and there are resistors which you can connect in parallel and drawn them into oil to cool them down (for higher loads), or ceramic 5W. (remember it can cut out if the amperage goes above the limit, P=U*I (power=voltage times amperage) for your example 120W=3V*I, I=40A soo keep in mind that formula, soo you don't pull your hair out whenever it shuts or cuts off if you connect).

I have 2 of these and i tried to hack one but not sucessfull.
But i think the voltage should be good.
You need a RIG for that, good example would be P4 120W one stick of ram and probably dedicated GPU (old one like HD 4890x2) which can up to 300W.

Most of PSU has warranty from 2 years to 5-7years (higher quality, not potato ones).
Usually they start to die after 3-4 years because heat+load on capacitors do its thing and also coils and dust etc.

For that PSU i wouldn't worry, multimeter is advised if you wanna test your pc under load (cheap ones will do also).
