So I was donated this Dell Optiplex 780 which I intend to use as a server for approximately 6 hours a day on weekdays (12+ on weekends and my holiday periods)

 

I noticed that the power supply has a drop of melted glue hanging from one of the holes in the underside. Then, when I was running CentOS 6.7, I noticed that when the PSU fan starts up it sounds very loud and rattly indeed. This needs replacing doesn't it?

 

If I were to buy a new PSU, it would make more sense to put the new one in my mother's PC so she can use my spare graphics card (her PSU can't handle it currently, and her current GPU isn't really very useful) but I don't know if her PSU would be up to the usage I have in mind for the Optiplex.

 

Server:

Dell Optiplex 780

Intel Core 2 Duo E7500 2.93 GHz

2x2 GB DDR3 RAM

2x 450GB HDDs RAID0

1TB HDD

Dell L305P-03 (305W?) PSU

planned usage: 35 mod Forge Minecraft 1.7.10 server as well as NAS for backups. I also have ideas about using it as a web server. (May share it's load with a virtual server on my main PC if I decide to get into web stuff)

 

My mother's PC:

FSP Group 300W PSU (I've heard it is capable of constant 300W which is apparently a big thing, I can get the model too if you need)

 

My mother is happy to keep her current setup and use mine when she needs to Chromecast something hers can't handle (Different sites seem to have different qualities. I'm very surprised, but the GPU actually makes a difference to the quality) The only reason I thought of this is because I thought if we are buying a new PSU, why not give it to her and therefore decommission the worst PSU?

I don't think that will be necessary. That'd probably power my main PC. I either be getting a new 300+W PSU from probably EVGA, or a 450/500W for my mother's and put the old 300W from her's in the Optiplex.

 

I can choose an individual PSU once I know if the old FSP unit is up to the job of high level use in the Optiplex. (It's about 5/6 years old but has never given any trouble)

 

Or perhaps the PSU currently in the Optiplex is fine and just needs an overhaul.
