When a GPU fails or when a motherboard fails, sometimes folks jump to the wrong conclusion and assume a card or board is faulty, when they are really having a problem with POWER! It is possible to test power issues with a multimeter, but this is burdensome, and if you make a mistake, it can cause costly damage to your gear. A quicker, easier way to test power issues is with a Power Supply Tester!

@2:00 The Plus four connecter has to be inserted first before the 20 pin in order to insert it all the way and also prevents it from sliding back out. There is a little tab on it that will prevent you from inserting it all the way in if you put it in last. The same pin prevents it from backing out when inserted in the correct order.

Good review my man. I've seen this same tester sold under 15-different brand names and they are all the same exact tester. The manufacturer is selling them to whoever wants to claim it is theirs, thus the generic name stamp.

I use the pc/sps tester to check the initial voltage without load. It won't tell you if the psu has issues, just if some of the voltage is not in range. Passmark has a physical psu tester that does even more testing than one of these simple testers, and it's in line, so you hook it up to a working system to impose load on the psu and test the voltages. Problem with the Passmark tool is that it doesn't work with server psu's or 12v only psu's (the new standard that has the psu components on the motherboard). In that case you can just populate a test system with gpus, hdds etc and impose a stress on the components to impose a high load on the server psu's. Alternatively there is other testers that are for electrical engineering... These can be a bit expensive and often not worth it unless your a psu manufacturer, and rma facility or something like that.

I been reading a course on PC repair. It tells you when you power on a power supply and test it with a multimeter. Make sure you a load on the power supply

[slybunda]

need to actually put a load on the psu to test it properly.

[tarikcollins]

what does the pg mean ? because i tested mines it was beeping with pg At 130. also let me add i’m testing a corsair Rm850x then i tested my old corsair v850w which tested normal pg and not beeping

[insidethreewide]

Thank you for this video. I just made a purchase via your Amazon link.

Hello Bro! I bought this item just from Amazon. I plugin in my 6 pin PSU power supply for my Goldshell mini doge miner, but it doesn't work. My question is do I need to connect 24pin power supply to work, or something wrong with device? Please any ideals otherwise I want to return it.

[THEONLYETP]

I have a similar unit and the PG is 0! But the PSU is fine and working with no issues. EVGA said the cheap testers do not test PG correctly. How could you get 0 and a unit be fully operational? Also other EVGA PSU test 100 and all of the non- EGVA test lower than they should. These units cannot be trusted to test PG properly. Volts are fine BTW!

[aglandorf]

Got that one today... Its Not turing on... Tomorrow I will get a new PSU...lets see whats going on with the device

[pettitbill]

My small 230W Dell PS doesn't have an off and on switch so when I plug in any cable the tester never comes on so how do I force the PS on to test it?

[luigiprovencher]

I just bought this and received it today.

[ramanmono]

My PG says 180ms but flashing and it gives a beeping sound. The voltages show correctly.

[deadhorse]

Thank you, I bought this same one today, but mine didnt come with instructions, so i plugged everything in, I take it from your video you just want to test one cable at a time?

[mikejohnson]

Excellent review ... but you bridged pin 16 to GND ... not pin 4... right?

[MarcsVlogVids]

Is it safe to test unknown cables on a modular power supply using a tester?

[orestesdd]

Where can I get the 24 pin connector diagram shown in your video? Thank you, and I bought the "tester" using your link.

[noone]

What if the PG is only 130ms like mine? the tester also keeps on beeping, does it mean my psu is defective? all other values are normal.

[acoatl]

I accidently plug the 6P connector (that goes to the graphics card) on the 4p to 8p (that goes motherboards ) and got sparks i already knew that power supply was faulty do you think i damaged the power supply tester? I tested another power supply after that and i it tested good even thought the second power supply did no had 6p for graphics cards.

I built a computer with used parts. On day 1, everything worked fine. On day 2 and 3 the RGB lights on my cheap "Darkflash" branded fans stopped working, but the fans would still spin. Around this time, I learned that the USB ports would only support my mouse and usb flash-drive intermittently. I disassembled the fans and I could see that each LED strip showed exactly 1 burnt out spot on a tiny circuit controller, but the burn marks were in different locations for each fan. I have sharp eyes but was unable to see any signs of burn related to the USB ports. Am I crazy to think the problem with the fans and the USB ports might have come from the power supply? And if so, would this tester help me to confirm the PSU as the source of the problem? PSU is a Corsair GS700. It's old, but I do still hope to use it. Thanks!
