Redundant consumer PSU's

[jadams]

I know this question is out there. But are there any redundant power supplies for consumer PCs?

not really. A UPS/battery backup is better protection for a consumer PC than a redundant power supply would be. there are ways to use more than one power supply to power your system if its a capacity issue. however if you are looking for fail-safe in case one dies- there really isnt any reason for a workstation that would justify the cost and comlexity. if your power supply dies, just take half an hour and install a new one. its not a server so there wont be hundreds of angry people emailing you because it goes down. a decent power supply fed with nice clean power from an active UPS should last for a decade or more. my Corsair 750w is approaching 10,000 hours probably.

not to mention almost no consumer cases have a spot for two or more power supplies. i think frozencpu.com had redundant supplies, but all of them that i have seen are rediculously expensive.

My application is very odd. It doesnt really fit your reasoning for not needing a theoretical redundant psu.

It doesnt even really have to be consumer grade, Just something ATX.

turns out this is exactly what i was looking for.

First week of September we will have a review of a PS2 (ATX) formfactor redundant unit that may be of interest.

 

[jadams]

can you provide any info on them?

something like the link i posted above. atx form factor with two real independent power supplies.

Um, ok. Well it would take a long time to link them individually but if you go to;

http://www.newegg.com/Index.aspx?name=Home

http://www.directron.com/powersupplies.html

etc.

Look for mini redundant in the search or product listing and they will be redundant units. Generally, those labeled mini-redundant will be ATX12v/PS2 width and height. The length on the units will vary, so without knowing your application I'll just say check the depth to make sure it will fit. Capacity in these units as well as connectors will be kind of limited, though the one that will come up in Sept is on the large end of the capacity scale.

Thanks.

I looked at newegg initially, but as it turns out their redundant psu's are in their server psu section. I didnt expect ATX psu's to be in the server section so i didnt even look. whoops!

Now that I know they actually exist this is very helpful. I look forward to the review as well.

Thanks again.

Look for Zippy units, pretty expensive but generally the best units in this segment..

How do these work? Do they have spliced wires so if one goes down the other auto picks it up?

A lot more complicated than that. I'm not saying that I'm an expert myself, but there is a controller board that regulates the input source. When it detects a loss of the input source, it switches to the other power supply unit. Well, that's just the basics anyways.
