## Description

As a leading brand in small form factor (SFF) case design and power supply miniaturization, SilverStone launched its second Flex ATX power supply, the FX500-G, to further widen the scope of SFF design possibilities and to serve upgrade needs of embedded systems or 1U rackmount server applications. It has features that enthusiasts demand such as all black exterior coating, sleeved cables and support for PCIe 8pin and 6pin connectors. In addition to 80 PLUS Gold level efficiency, the FX500-G features powerful single +12V rail and 24/7 40℃ continuous 500W output capability to provide reliable and high-performing system operation.

Review: Es una buena fuente, pero bastante ruidosa.
Review: 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.
