Server power supplies.. uh oh

[shovenose]

So I needed to assemble some budget servers for a couple clients that wanted to pay less... and to save on cost I'm using random PSUs I already had...
Antec Basiq 500W
Antec True 380W (partially recapped at some point)
LiteOn 250W
Logisys "480W" lol... <-- gutless wonder
HEC Orion "585W" lol... <-- slightly less gutless wonder but absolutely no input filtering


The Logisys was in a friend's server for several months working fine... pulled from a customers old PC. So it's certainly been tested to be functional :P the Orion came from somebody online basically paid nothing for it. Good choices? :P

Re: Server power supplies.. uh oh

The Logisys? In a server? Are you kidding? You should NEVER have used than in ANY computer, let alone a server, regardless of the budget. If it were me, I would have killed it as soon as I got my hands on it, either with the load tester or the sledge hammer.

Logisys? *screams like a girl* no! never!

it works and it's free... These servers aren't going to be stressing it much.

Re: Server power supplies.. uh oh

Even with Logisys, it depends. Some of their "higher end" units are made by Keerda and will probably be okay up to 275W. At least some of those have CLC on each rail. They're still not reliable with crap fans and BH caps but better than their super low end ones with one cap per rail.

The Basiq is an old FSP unit that runs hot and will toast the Teapo caps.

I wouldn't touch the TruePower without a FULL recap, period.

The LiteOn 250W is probably well built but probably also needs some new caps.

That HEC Orion is a mediocre 350W PSU. I'm sure you've seen the one I rebuilt, I have it in a light server But I did a full recap and added an input filter

Would love some pics

Re: Server power supplies.. uh oh

150w-250w max. with 60-70% efficiency.
Usually efficiency is important for dedicated servers... don't you pay for Amps for the rack?

On the contrary, it will be the Deer stressing those systems.

You have been warned, even after others' threads of lousy power supplies- why even do this? Just because "it works and was free?" What does that even mean?

Those scrap POSes that impersonate power supplies are only going to leave you with more scrap metal.

150w-250w max. with 60-70% efficiency.

You're confusing efficiency with power factor. I can connect a big enough cap to the line and draw 30A at 240V, with only a few watts of I2R losses in the wiring connecting said cap. IOW, nearly zero PF, even a x amps.

I can also have a load whose PF is .9 or higher, yet have miserable efficiency.

Power factor has no bearing on efficiency! There was a flamefest a few years ago over this! Superstition never dies!

Stop spreading incorrect information!

That thing (I'm not even going to call it a "power supply"... it looks more like a "fire supply" or a "ripple supply" depending on what goes first) looks only slightly less gutless than "Hercules", whose review ended with "If you have one of these, shut your system down and throw it away. NOW.".

Why look, this thing is supposedly good for servers. Let me ask you this - are you going to put a $20 power supply in a server? If so, come over here so I can smack you. Better yet, wait for the load testing pages so I can show you the consequences of such a deed.

better yet come over here, we will smack the acne off your face! i'll even have my tube radio buddies come along.

I didn't bring the power factor into the equation, you did.

Fact is, with or without the power factor, those power supplies have lousy efficiency.
A datacenter usually quotes a particular value per unit so if shove rents a rack in a datacenter, or space, he's limited by the amps available.

The datacenter I have a few servers at gives 0.5A per 1U (230v input though), or 16 A per 42U rack. I would think he would want higher efficiency.

Junk caps, junk fan, laughable input filtering, tiny heat sinks, all the usual things wrong with a cheap and nasty unit. Working or not, just get that thing out of the computer and sledgehammer it already!

You need to draw the line somewhere... putting junk units inside a customer's server, whether they ask for it or not, is asking for trouble.

I have quite a few old review samples sitting around the house I probably could sell. But I have standards. I won't let something go out the door I wouldn't use personally, because if something leaves this house and then dies in an epic flameout the customer then blames me. "Well, you let me buy it, so it's your fault!"

The only one on the list I'd even consider using is the Basiq.

Okaaaaaay...

Re: Server power supplies.. uh oh

Is this setup going in a shared rack? Will there be concerns when your EMI produced by the filter-free power supply drops the bitrates/packet rates on other racks? Because that will happen on gigabit interfaces. And you will piss everyone else off within five rack units of your server. Oh, and that will be handy in pointing out which server is causing the problem .

Re: Server power supplies.. uh oh

Not only is that Logisys horrible, it also looks like it's already had quite a bit of running time. Who knows when those cheap nicon caps will pop. I'd also be worried about how much oil is left in the bearing of that cheap fan

Okaaaaaay...

Well the 800W in win you sold me? The fan is already going out. and that's supposed to be a good power supply.

The rack is in my room so no other customers will be bothered by it. Network here is a wireless link to two cities away.

This shit can suck in every other way may as well use junk power supplies.
Not sure why I even made this thread lol

Re: Server power supplies.. uh oh

Still why would you risk using that in any server? At least use the Basiq in there after checking to make sure none of the caps are bulging.

um no ALL of these power supplies are being put into production.


If it bothers anybody sure, you can buy me new power supplies.

I'm outta here.

Re: Server power supplies.. uh oh

We're not trying to be mean, just don't want you to fry your server lol

[tom66]

Re: Server power supplies.. uh oh

It's kinda funny I can pick up a decent 300W FSP with Teapos for around £10 here (used price.) They work fine and can do 300W and have line filtering. It's silly to risk hundreds in hardware to save a few bucks, but if you're not going to listen to any advice why did you bother making a post?
