what PSU would I need?

[kidlat020]

Hello peeps. first time here (or second? whatever). please pick me a power supply.

 

I am a cyber cafe owner running diskless environment. to explain with a little trivia, diskless means no disk. the client is instead booting from LAN and a server with bootable OS (and games) will be on standby to provide said boot. pretty neat when you're managing something like 50+ computer clients, all sharing a single OS image. even more amazing is that the OS image is read only (requires a password to be read and write). meaning zero headaches for viruses.

 

back on my query. my specs are as follows

 

A6 5400k

motherboard

4g ram

 

... and that's it. according to my wattmeter, one unit is consuming 50-55 watts in-game. what's the best PSU pick for this build? something cheap, but 85% efficient

 

and for my diskless server (the one giving the boot OS to clients), its specs are

 

intel g1840

motherboard

8g ram

2x WD blue 1tb

1x plextor SSD 128gb

nvidia gt730 (because I also play in the server)

 

...what's the best PSU for this little server? hoping 90% efficiency as the server is running 17 hours a day.

This PSU will be good for both types of computers. It's a 430W from EVGA with a basic 80+ rating. It comes in at $25 after rebates.

pretty tempting for its price despite being only 80% efficient.

 

is 430 watts really the lowest? and here I thought I could easily steal an 85% PSU as long as its low watts.

Both of these are good quality 80+ Bronze PSUs choose which one you like the 500w would be better for the host pc while the 430w would be perfect for the clients: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026

Your not really gonna find anything in the 400-500w range that is 80+ Gold and low priced.

It is the lowest common one from quality brands, yes. And actually the really efficient PSUs are the ones pushing high wattages, as there's always a little overhead to keep the electronics inside them alive.

I guess I'm stuck at 82% efficiency if I want to be a bit cheaper.
