SilverStone Technology FX500-G, 500W Flex ATX 80 Plus Gold Power Supply, SST-FX500-G

This PSU is exactly what the title is, beautiful until you hear her screaming. It's normal from the start but as the load kicks in, it sounds like a maniac!

Es una buena fuente, pero bastante ruidosa.

This is pretty much the only 500w flex psu you’re going to find, so I’m thankful for that. But the fan is unbearably loud with a really high pitch whine to boot. I knew this going into the SFF build I was doing, but it was truly unbearable. I ended up opening the psu and splicing an in-line potentiometer on one of the fan cables that is outside the case, so now I have a knob to manually turn the fan speed down. I looked at replacing the fan with a quieter one, but it’s a 15mm thick high rpm fan. The 20mm will not fit, and the 10mm leave a gap and don’t push enough air. The potentiometer solution works well, but it will likely void your warranty and is somewhat dangerous if you don’t know what your doing. But like I said, it’s pretty much your only option, so proceed with caution.

Putting this next to your desk will give you a new appreciation for your headphones.

Cables are low key too long for SFF, that's okay. Cables are stiff, that happens. What I do not understand is how this fan is so loud. I measured it with Spectroid and it gives off white house from around 700Hz all the way to 7kHz! You see where there entire top spectrum gets quieter about half way through? That is entirely the PSU's fan! I naively thought I could find a way to silence this or maybe get used to it. The only way you can stand this fan is if you're partially deaf. It sounds identical to the fans used in data centers. It isn't just a fan noise, there is also a loud machine signal sound. I like Silverstone as a whole, but this PSU's noise is ridiculous to the point I'm wondering if they even tested this before selling it. I really regret my purchase :| I'm going to have to void my warranty or return this thing. Edit: Decided to try to switch the fan. Oh boy. Just don't buy this. Whoever designed this thing not only added extremely long stiff cables that make it almost impossible to fit it into a small form factor case, PLUS the noisy fan, they even deliberately chose a fan that is hard to switch out, and they added a hidden piece of metal with a hidden screw (literally does nothing except bend if you try to open it). This thing is trash. Does it power on and supply power? Yes. That is where the pros end and everything else is a con. It is even technically bigger than flex spec and it makes everything difficult. Do not be a moron like me, buy something else. I'm at the point where I look forward to this thing dying so I can replace it. Buy literally anything else with decent reviews. You WILL regret it if you buy this.
