Summary: Would always recommend the Semi-Modular version, something I did not do. However, it is still possible to get by without this, however it just makes the build a little bit more of a mess to view. No problems, very quiet (my fans in the case are louder). Will run any mid-range pc build with ease, although it might be worth to go bigger to prepare for any further upgrades.
Summary: Great little PSU. Cables fantastic quality. Sadly doesnt fit in my old case as the fan is on the top (or bottom depending on which way up you fit it) instead of at the back. But I have ordered a new case now! It powers my R9 270X completely fine and has the proper connectors so I didnt need to use molex adaptors. Just make sure you only need 500W, they do make bigger ones (600, 700, etc). Quiet as a mouse aswell.
Summary: I have an XPS8100 which came with a 350W power supply. Over the years I've added a second SATA board which allowed me to add 2 big SATA 3 Disks Recently the machine started randomly switching off and after much fruitless diagnostics, I came to the conclusion that the power supply was the most likely culprit.
Summary: Can't really give a review based on the reliability of the psu as of yet, as i have just received this item. However, there are plenty of cables to attach your required hard ware to, and there is adequate cable length with each wire also. I cannot even hear the fan inside the PSU itself, and the actual front and rear fans of my case (Bitfenix Prodigy mini-ITX) are somewhat louder.
Summary: Got this to replace a cheapo PSU on an I7 setup brought of eBay, the original PSU supplied sounded like a small turbine at full throttle and was really annoying. after reading some of the reviews purchased this. Upon fitting found it was missing a 12 volt 4 pin connector, but have used a 6 pin connector instead but just haven't used the tow "outer" pins. This unit is incredibly quiet and seems very well built. good purchase !
