I know the 132W is quite close to what I will need, but my current build uses only this much power if I play CS:Go, Doom Eternal and similar FPS games. That's not exactly the intended use for the next project, it should be mainly for media playback and maybe some light emulator gaming. So it might be doable, or I might try to get a 3400GE, there are some to be found at around 200 EUR on Ebay.I see:
I would not use it with my B01T3, as it is drawing around 115W from the wall during bench tests. Much too close to this LED PSU limit.
- Working Temperature -20°C ÷ +45°C
And according to my heat gun, my MW PSU is getting hotter than 50°C with passive heat transfer to the casing only.
All that with ripple at 180mV while ATX specs for 12V is 120mV max.
Could work with less powerful hardware components, but that still looks risky...
Ripple might be an issue, but that also depends on what the power grid spits out, so it might work out too.
That leaves the question of temperature open. I am not really sure how to interpret the values given for this PSU. It is meant to be built into cabinets, so I think the creators must have been aware that airflow might be restricted. The PDF states:
Range: 110°C ± 10°C
Type: shut down output voltage. Re-power on to recovery.
Working Temperature -20°C ÷ +45°C
Working Humidity 45 ÷ 85% RH non-condensing
Storage Temperature and Humidity -30°C ÷ +70°C, 10 ÷ 95% RH non-condensing
So if the PSU itself should not get hotter than 45C, a shutdown at 110C (or between 100C to 120C) wouldn't really make sense. Other websites state the values as environmental temperature max 45C and operating temperature max. 85C. But I have to admit, I have no idea how this PSU will transfer heat, as it obviously has no fan and no metal case to transfer or dissipate heat...
Edit: just noticed that the PDF says: "Cooling by free air convection". Since it will be mounted against the metal front plate, it might be enough to add a small 40x10mm fan to the case...
PS: the MeanWell LSP-160-12T has a ripple of 240, as found in their specs
