Micronics Wizmax G 1000W ATX v3.1 PSU Review

Average Noise

The PSU’s average noise output is low, dropping below 20 dBA at 230V, where the platform is more efficient.

The fan’s stop feature lasts till around 425W at 12V, and is affected by the load on the minor rails. The higher the load at 5V and 3.3V, the less the fan stop feature lasts. Moreover, I noticed three regions at light and moderate loads where the PSU’s fan has to spin at high speeds, to remove the heat, with its noise suddenly increasing above 25 dBA. This can be annoying for users, and this is the reason I prefer the fan to spin constantly under low speeds at light loads. At around 765W, the fan’s speed exceeds 25 dBA, and the 30 dBA mark is surpassed at close to the PSU’s full load output (>975W).

At 230V, at lower loads, during the fan stop feature, there isn’t a period during which the fan starts spinning at above 25 dBA noise levels. Moreover, there is no >30 dBA noise operation.

  1. i was able to get this thermalright TR KG850 on sale for $36, i was wondering how bad it would be if i used a 300W GPU (9070 XT hellhound OC) since the cables are only 18AWG.

    PS: and I’d like to humbly request that someone could test this PSU as I havent found anyone. it came out in 2025, and has a 5 year warranty.

    even more interestingly a better PSU, TR-AG850 has a 10 year warranty which may be a competitor at the high end of PSUs.

      1. thanks! I’ve just emailed Thermalright recommending them to contact you, not sure if that’s how it’s supposed to work but hopefully they follow up.

  2. Thx aris for a review, btw do you have any Cybenetics updates for XPG Pymcore series can’t wait to see the internals ?
