Hard to measure, but based on experience, how long should / will they last? I also think LPS life expectancy is hard to measure, and based on my experience, going with a good reputable company should go a long way. In addition to the better life expectancy from their LPS, these companies normally will offer either warranty to cover early failures or will provide support / service after the warranty period, and in the case of configuration changed in the setup, resell value typically is much better. Companies like Custom HiFi Cable (Sean Jacob's DC3 / DC4), Uptone, Farad...etc., are the ones I recommend, and based on my single data point experience, I have been running their power supplies 24x7 and some were as early as 2015 without issue.

di-fi Posted August 25, 2021 Share Posted August 25, 2021 So LPS can die after 3-4 years or sometimes 6 years. 24x7 that is. I am using Uptone (3 yrs) and Farad (2 yrs) Example of LPS components hard to source or hugely expensive according to my manufacturer (quote) : ''Particularly impossible has been the main FPGA used as well as the 10-per-board opto-isolators. We usually pay xxx for the FPGA. A spot-market source in (edit) just quoted us xxx each! 34x! Impossible and insane.'' That's a huge problem for manufacturers, great warranty or not Link to comment

Yes i agree this thing is quite fragile… but i dont see the real need to incorporate one into a pure audiophile lps….except for some fancy features like thermal monitoring, user selectable voltage settings… these features and the FPGA create interference and noise to the psu output… Builder of Linear Power Supplies Link to comment
Mags Posted August 25, 2021 Share Posted August 25, 2021 IMO, all a LPS needs are a box, transformers, diodes, chokes, capacitors, wires and connectors. All the rest are frills. Link to comment

That's a huge problem for manufacturers, great warranty or not Based on my use experience, I would estimate DC3/4, JS-2 types of LPS that uses quality components could last at least 10 years. Not sure why a quality LPS will need FPGA or opto-isolators, since none of the LPS's I use contain any of these components, but on the other hand, global raw material market is getting harder by the day to source components, so the price for LPS are expected to go up or already gone up, just matter of time.

Although understanding what is inside might help to select an LPS with more durable components. Thats the advice I am looking for. I think 3-4 years is not good enough for a 450$-650$ LPS. Or the other way round, if those last only 3-4 years I might go sooner with Sean Jacobs for example ;-). Where is the break-even point? For example if I paid 150-200$ a year that equals a 1000$ LPS (if it lastst 10 years) I probably get better sound also . So replacing both my broken LPS I will definitely need to evaluate duarbility of components. Link to comment
mikicasellas Posted August 28, 2021 Share Posted August 28, 2021 Hi Guys, Has anyone suffered from this issue before ? I turned on my server (ROG MAXIMUS XIII HERO Z590 with an Intel i7-10700K) a few days back and suddenly a message appeared: "USB Device Over Current Status Detected": So I swapped the JCAT XE USB card which caused the alert and put a Startech PCIE USB card instead without an issue, I also checked all the PCIE slots with the Startech and worked without an issue. I then downgraded the BIOS to see if maybe the problem could have been that way cause a few weeks back I upgraded the BIOS to the last firmware and all was the same. After all this checking and honestly with my limited knowledge on this, I keep wondering if something else could be making this issue or is it for sure that the USB PCIE card is the one that got damaged ? Should i look into someting else perhaps ? Thanks ! Link to comment

Have you tried XE card in all other PCIe slots with same message now? Did you try removing USB cable(s) when XE card show error message? Have you try different USB cable? Link to comment
