Why is this power supply so good?

PC Power and Cooling 510 SLI

I saw one on FS/FT and posters were very excited it was going for $140. So what makes this power supply so good (and expensive)? I'm not doubting it is, but I'd like to know why it's better than say, this Ultra PSU.

I saw that the max output on the Ultra was 550 as opposed to a 650 on the PC power and cooling and the +12v's were alot higher on the P&C. How else could I differentiate the two by looking at their stats?

www.badcaps.net is a good forum for getting info on the various PSU builders. They have interal pictures of a lot of power supplies.

Why is the PCP&C better?

Most likely: Better heatsink, better layout, better components (caps, wire guage, etc). Not overrated on any rails, etc.

PCP&C is generally thought to be the most reliable of all the psu brands. Personally I think they are somewhat overpriced, as they cost about twice as much as comparable good-quality psus.

Correct as far as retail non-commercial units go. Zippy and a few others can still put one in their place, but the price on some of those is breathtaking.

Ultra PSUs are never good, unreliable, all commercial and embellished ratings, rails, voltages, you get the idea. PC P&C is the opposite, yet still a little over priced.

The PCP&C is a higher quality server grade unit. It has better hold up time & warranty, tighter regulation, is rated at higher temp., & doesn't go by peak output for it's rating to name some of the reasons.

What makes it better? The individual components. Their rated wattage is the wattage it can sustain in real world conditions (not conditions in a lab @ freezing, as most other companies have it deceptively).

As far as server PSU's, I'm not sure PCP makes them to large OEM's. I know eMacs (Zippy) is a large supplier of server PSU's.
