I'd get the zippy DBtelos recommended. That's the gaming power series. One of the best psus ever made IMO. Pretty hot price too... will run anything you throw at it other than quad sli and dual x1900xtx.

Zippy's server PSUs are better, but for the general gaming community the gaming series is about as good as it gets :D

The Zippy 500W gaming PSU is liittle different from the server unit internally.

The minumum load on the 5V is 2.5A and it better be present or the 12V suffers.

At mid-output it's only 74% efficient. It's a good unit but the 5V better be loaded.

What are some devices that use the 5v rail? RAM? USB? sound cards? optical drives?

RAM is uaually 3.3.

5V in a current machine is typically for PCI cards, all USB, and the logic boards for all drives, optical and HDD.

So a typical current system would be able to put out 2.5A or so on the 5V rail then, right? Thanks for the link Galvanized.

A gaming system with one optical and one HDD may need a ballast for the 5V line to load it up.

PCP&C offers a resistor in thier accesories section. Look it up, I'm too lazy to link.

the zippy power calculator is a bit outdated. The extreme psu calculator has all the latest components.

Yeah. But it's not broken down by amps per rail and supposedly the calculations are based on the maximum THD of each component.

Well thank you Captain Obvious!!

dBTelos questioned what posed 5V loading on the PSU. THAT'S why I suggested he look at it, because it shows the load on EACH rail.

Are you just neffing acegazda? ;)

NOTE: Takaman's calculator is no longer being up-dated. The Zippy calculator is based on Takaman's very good work. No one is forcing anyone to use it.
