Question about PSU Tester revealing low PG values for several new PSUs.
Question about PSU Tester revealing low PG values for several new PSUs.
The PSU tester indicates low PG values for two new 1000W units, one from Corsair and one from MSI. The device was bought in 2017 and normally gives a range of 180 for a known good Corsair 750W supply. Both tech support from Corsair and MSI suggest returning the units. Should I continue purchasing new power supplies until finding a reliable one? A different tester? Should I buy elsewhere besides Amazon? Any advice is appreciated.
The consequences of PG dropping below 100 at times would need careful evaluation. Trusting a new build with a PSU that passes a no-load test might seem safe, but hidden issues could still exist.
How much did this psu tester cost you?
If it was under $5000 I would apply a discount to the results.
Static testing can verify a dead psu, but it doesn’t indicate how well the unit operates dynamically.
Are you experiencing an issue with a psu?
Could both factors be contributing to the problem?
It’s highly improbable that two high-quality power supplies would fail together.
The testers being used are inexpensive, yet both Corsair and MSI tech support advised returning the units due to low PG values. The power supplies in question are for a new build, and both reported low PG values upon first powerup. It seems unlikely that two high-quality supplies from different makers would fail a basic no-load test.
