### ⭐⭐⭐⭐⭐ Quiet but smelly?
*by A***L on August 24, 2023*

My computer was shutting down randomly a few months after buying a new graphics card. The PSU was 11 yrs old, so although it was 650w and the minimum suggestion from AMD, I didn't feel it was quite right. I also needed extension/splitter cables to fit the plugs on the new graphics card since the old PSU didn't have 16 pins cords... not a good look. This came with more plugs than I needed (hallelujah for modular designs), and fit my 6700XT perfectly. I used both of the 8pin cables and plugged them both into the 2 PCIE slots on the PSU, instead of using just one wire with the additional 8-pin attachment. (see attached). After giving up on my defective RAM sticks (again), I've since had no BSOD error, or random system crashes / freezes that lose all my hard work throughout the day. The crashes I faced before were almost certainly the fault of my old, failing / struggling PSU, but if I run into them again I'll update this review. Even if I face those issues again, it wouldn't be the fault of this product, but I did want to make note of it because system crashes can be linked to failing PSU's and people need to be assured of that when considering applicable remedies; for me this was a purchase out of necessity, not comfort / preference. The PSU itself is also ultra quiet. For the first couple days, I smelled a factory-like scent. It was a little strong, but it has been a few days now and has gone away. I always thought my graphics card / HDD was making noise--it turns out it was my old PSU, because now I hear ALMOST NOTHING from my tower, and certainly nothing from the PSU. This is a great, great buy.
