help with choosing the right psu for new build

[kaos]

hi,

 

so ive done alot of research into building a descent pc. im not into pc gaming its more to be used for all other aspects like internet browsing and also watching hd movies stored on it etc.

 

i have decided on the Gigabyte GA-B75M-D3H mobo with the intel core 3450 3.1ghz cpu and 8gb ram.

 

the case i would like is the fractal design define mini and i have a hdd and dvd writer sorted.

 

the only thing i cannot decide on is the psu!

as i said im not into high end gaming so wont have a huge graphics card. i have a nvidia 440gt and a nvidia 9500gt which i can use and will be surfficent for me.

 

there are so many psu's to choose from and even then i cannot decide. i know a few things that i want from a psu but cant seem to find one i am confident enough to buy to make sure it does everything i need.

 

i know i need:

a 24 pin main power connector for the mobo

80+ certified

sata power connectors for hdd's and dvd

 

some things i am not sure about are:

 

cpu power?? which connector is needed for this mobo?

what is a com connector?? this mobo has one

what is the significance of a 20+4 pin connector? does that mean i can plug the 20pin and the 4 pin into my 24pin main power connector :confused:

 

could you recommend a couple good psu's? i think id like in the region of between 500w and 750w incase of future expansion, but also its important that it is certified for efficiency and that i will have all the connectors i need.

 

my head hurts when i try to decide!

 

thanks in advance :)

 

this mobo has only 1 system fan header. does that mean i can only run 1 fan for cooling? can i get an adapter to run maybe 3 fans from that header?

750 Watt

As your not a gamer, 550 watt is more than enough for you.

The CPU power is a 4 (or 4+4) pin power connector (not linked with the 24) that connects above the CPU location

I'm not sure about the COM output, my motherboard doesn't have one, someone else may know.

24 pin connector is standard now, it used to be less along time ago (I think......), so when they state 20+4, it is 24 for the motherboard.

 

I wouldn't recommend splitting a header 3 ways. You can get an adapter to split it into 2, which is fine. As your not a gamer, or a "hard core user" your PC isn't going to let off much heat, so cooling wont be much of an issue.

Your motherboard comes with monitoring, so you can keep an eye on temperatures.
