![]() It is hard, I would not do it, especially not 400W. Doing more 200W passive is another topic. Laptop chargers do work fine, ain't it? Now with GaN the bar is higher. There are no problems with loads under ~150W. It takes only one cap near some hot element to make problems, like some additional voltages for logic, then a domino effect can occur due to instability taking out semiconductors. The obvious problem is capacitor lifespan as their aging is also ambient temperature dependent(besides ripple). PSU's usually doesn't have more than two temp probes, you cannot put them everywhere on each component. It spins up like once an hour and then stops. It is not spread evenly.īest of both worlds are hybrid fanless. Funny how this Tacens got fanless mode right in 2007-2008 before first fanless Corsairs lol. Now I use 2 such PSUs in my rigs: New Cooler Master V550 Gold V2 and old Tacens Valeo III 500 W, and haven't had issues since. I actually fanswapped my old LEPA G650-MAS due to this exact issue, and early fanless Corsairs suffered from this as well. There is also some sort of thresholding for that typically, because at voltages close to startup fan might attempt but struggle to run, generating buzzing noise. Typically, there is an NTC thermistor inside, which, when heated high enough, drops resistance low enough, so current passing allows the fan to start. It's usually turned on by internal temperature. Even if you do proper PSU breakdown and find dead component(s), you can only suppose higher operating temperatures accelerated their demise, but again, this is unprovable (and personally I find it doubtful, especially if failure happened within warranty period, as I would expect engineers designing the PSU to spec for such period) We also offer volume and academic licensing, and discounts those who upgrade from Bookdog.You cannot conclusively prove your PSU failure was due to it being fanless.
