Xilence PSU really are quite poor quality.
16 Apr
So today I went out and purchased a couple of Xilence PSU (XP500), specifically because they were rated at 30.0A at 3V3.
We needed a fairly strong 3V3 supply rail to feed a couple of maxim buck converters down to 0.98v for an FPGA project.
You would think that 3V3@30A would be able to handle such a simple situation.
Well you would be dead wrong..
After loading the PSU upto 6A the supply rail dropped to 3v1 we then added another 6A load and the rail hit 2V98 Also the 12V rail began to sag down to 11v8 volts and the 5V rail hit 4V8, even with no loading applied to anything other than the 3V3 rail.
Considering these supplies are rated at 3V3@30A, we should not see such poor power degradation with what is basically a 12A loading on the 3V3 rail.
By the time we were at 18A@3v3 the 3v3 rail was below 2v9 and the 12V rail was also in decline.
Furthermore the power supply started to make a sound as if there was a screw loose in the cooling fan, removal of the load caused the sound to disappear.
I’m of the mind that something was breaking down inside the PSU whenever the 3V3 supply was loaded.
OK fine let us contact their support…
After finally getting their support system to accept the email request and supplying the PSU serial number
I STILL have NOT had a reply after 7 Days….
Is the quality of the Xilence PSU bad or is the application unsuitable?
Well, to put this in perspective, I also purchased a really shitty Chinese made ATX-320T PSU that claims it can supply 3v3@14A, this thing cost less than $11USD(I kid you not)
After 4 months at an overload of 18A@3v3 the supply rail on the Chinese PSU has dipped down to 3V2 the 12V rail is at 12V2 and the thing is still as quiet as a whisper, plus no magic blue smoke daemon has appeared.
Recommendation
Do not EVER buy Xilence PSU’s, it may even be better to purchase that shittly little Chinese brand after all.
Conclusion
Xilence PSU’s appear to suck ass so badly that you would NOT want one inside your computer.
By the way their internal build quality on the PSU is basically ‘Fucking abysmal’, parts of the inline filter are ‘flapping about’ in the air as if it was an afterthought needed to pass the EMI standards.
Whilst there may be many Xilence the market, such poor power regulation can only lead to seriously stressed computer parts and early failure of equipment.
Time to return this Xilence crap to the shop and save some serious money.
