Tom's wiki rates this as a Tier 2 power supply. Right now newegg is selling them for $55 after MIR. I though this was a great buy, but then I started reading all the reviews on newegg and I am not sure.
Listen to the Tier rating and not the newegg customers. Half of them have no idea what they are talking about. One person destroyed his PSU because he failed to ground himself and static shocked his unit. He said he would never buy that unit again and blamed the manu for his own error even after they replaced the unit for free. (yes he admitted to the static shock)
I've built three systems with Antec supplies this year. So far no problems. I've used two EarthWatt models (380 & 430) which are supposed to be similar to the Neo model and I've used one Neo 550. My experience has been that they are a quality power supplies at a bargain price. SilentPCReview, also thinks well of them. On the other hand, SeaSonic and Corsair have sweet power supplies.
Yeah, I was just throwing the names out there. Looks like I'm going to be building another system. After all my positive experiences with Antec (cases and power supplies), I've got no justification to spend another fifty dollars or so on a Corsair power supply. So, I will be ordering a Neo 550 this week. I like quiet cases, I like quiet power supplies.
