Server PSU
 

Who on the forums was converting and selling these? Are they safe? I race with an 8 year old. I have seen a few that were shrink wrapped, does this cause heating issues? I currently have a protek 20amp that works fine, but I actually need around 30amps to do what I want. Dont really need more.

If your worried about 'safe' you probably don't need a larger power supply...


That being said:

They are as safe as any other power supply out there. Most have an overcurrent/short/etc protection on them that is a little trigger happy.

I have to plug in my chargers before I turn the PSU on otherwise it detects a short...

I just did a conversion on a 500A Corsair PC PSU (bought new) today, puts out 38A on the 12V line. Took me about an hour to convert. Total of $45 spent.

PM and Ill send you a link to a great site with all the info.

I wouldn't be concerned about the electrical safety of single server supplies, as mentioned they are pretty good. Physically though they don't have nice finished chassis, they may have some sharper edges than a more finished case consumer supply.

Many of the ones ran in series for 24V violate proper grounding practice, in the event of some component failures they risk the case going live. Why some enclose them in a non conductive case of some sort.

I think Dave H covered most of the points. I have been using a 12V, 800W one, but don't actually use it above 20A (I just have no need). The shrink wrap is usually to cover the ugly case and manufacturer's sticker, and also as Dave pointed out, to cover the sharp edges from punching the case metal out during manufacturing.

There is a large thread on RCgroups which covers it
