Pros: Stable voltages, apparently regulates 5V rail independently, good for boards which depend on that rail. LED on back lets you know when the capacitors have discharged, so you don't start working in the machine while it still has power. Fan seems mild and quiet. I have some adjacent noise sources which keep me from noticing if it's loud or not. I don't hear it anyway. Relatively good capacitors (Teapo). PSU is heavy. Used by major OEMs, which is a good indication that it's reliable enough to withstand a major PC's warranty period. Some are critical of OEM power supplies based on their wattage ratings, but they are better built than most of the junk people buy at retail. If 300W is enough for you, then you can't go wrong with this unit.
Cons: Some things people need to know before buying: - Because it's an OEM design, the extra pins on the 24-pin connector are not detachable. If you have a 20-pin motherboard then you will probably need an adapter. Newegg sells these. Theoretically you can overlap the extra pins but there's almost always something in the way. Even with the price of an adapter this PSU is still a bargain. - There's no switch to cut off the standby power. You have to unplug it. - Newegg now is selling 350W HiPro models for not much more. I'd consider those next time.
Overall Review: This power supply appears to regulate the 5V rail independently, unlike many other PSU's. This makes it work better with boards like the Epox EP-8K7A which have a very biased dependence on the 5V rail. Some 8K7A's still sag the 5V a bit with this PSU, but not enough to cause instability. If you need more juice then I'd check the 350W model newegg is also selling. HiPro has more trustworthy wattage claims than many other brands. I opened my PSU recently and it has Teapo capacitors throughout. Teapos are good enough that they're unlikely to fail, even though there are better brands they could have used. Most power supplies have very cheap caps which will die before these Teapos do.
