I have an Asus Dseb-Dg motherboard and there is a problem with the PSU

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

The PSU I purchased was a 20 pin but I purchased a 20 pin to 24 pin converter and it still does not work. I read a review about problems with Asus motherboards and they said that it is essential for the 24 pin motherboard to have a 24 pin connector. I am going to buy a new power supply but does the power supply have to be a 24 pin or can it be a 20 + 4 pin. Thanks a lot for anyone's help.

What PSU did you buy? Any modern day PSU should be 20+4 which should work fine. Also, you did connect the 2x CPU power connectors right?

Most if not all PSUs are 20 + 4 for a total of 24 pins (actually 23 pins are used).

The PSU was missing one connector (4 pin). I have a Asus Dseb-Dg motherboard

http://www.newegg.com/Product/Prod [...] 6813131250

I want a redundant power supply because I want a server for websites that need to be up 24/7

I have two 640gb hard drives 3x 120mm fans, 2x 250mm fans for the case, a optical drive and a single xeon 5400 CPU

A member told in this thread (http://www.tomshardware.com/forum/284555-28-will-full-t...) me that this PSU (http://www.newegg.com/Product/Product.aspx?Item=N82E168...) was outdated and should not be used. Which redundant power supply would you recommend for my setup (around or lower than $350)

Thanks a lot

Unfortunately the link to your PSU doesn't work. You want a redundant PSU, but will the disk subsystem also be redundant, i.e, are the hard disks set in a RAID1 configuration? Will the PSU be connected to two separate UPS in case one fails?

I have to hard drives in Raid 1. I don't need anything else right now. I want a redundant power supply so that my computer is up 24/7. I don't have a UPS so that isn't a problem. A member told me that the PSU is bad because

"Is this for an older motherboard with 5V CPU?
That particular PSU isnt a great choice for modern motherboards.
It's an older model with -5V and very low +12V amperage. "

Will you install a GPU that draws a lot of power on your server? Probably not, but there are better single PSUs. Unfortunately the redundant PSU selection is rather limited and they need to be twice as powerful as a single PSU.

I don't understand the redundant PSU requirement, but no UPS requirement. Please explain your reasoning as it doesn't make much sense to me. The likelihood of a power outage is far greater than a PSU going bad. I haven't seen a single quality PSU fail for the last 10 years or more, but I've seen several power outages.

So you think it would be better to get a UPS instead of a redundant PSU? What UPS would you recommend for such a s system? And I don't think I will be installing a GPU. I will have a several videos on my site but nothing major. Thanks

How could a redundant PSU help if there's a power outage? An APC Smart-UPS 1000 or a Smart-UPS 1500 certainly would meet your requirements. I use both and they are excellent UPS. I bought my APC Smart-UPS 1500 used last year for $200. This site sells refurbished units in North America: http://excessups.com/

^ Exactly! A redundant PSU will not help with a power outage, you want a UPS for that.

Anyways, a GOOD high quality PSU, ie PC Power & Cooling 750, Corsair 750TX,etc are a good choice for a server. I used a PC Power on a 2P Nehalem based rendering station built for a neighbor and no problems with it so far running 24/7.

That sure is a high quality PSU. It looks like it has all of the connectors required for your motherboard; you certainly made an excellent choice.
