PSU Query

PrOdiGy1 · 29 Dec 2006 at 10:30

Posted this in another thread but i got no response so here it is again....

Just wondering what sort of PSU power i would need to run a system such as:

e6600
256mb x850xt AGP
2gb XMS C2 ram
Sound Blaster X-fi fatality
120gb SATA hd
and 1 or 2 cd drives

i currently have a 380w one and i have a feeling that isnt going to be enough. i have ordered OCZ modstream 450W one though as that is within my budget but it occured to me that i didnt actually check if it was sufficient for me setup.....

The OCZ will most likely be enough. However, if I were buying this system or if I was recommending it to a friend, I'd spec something a little higher. Maybe something over 500w, e.g. Tagan 530W Modular.

If you choose not to change it, I would say that it should work ok. Are you looking to overclock?

bah i knew id make a goof somewhere

and no i dont plan on overclocking tbh as im getting the ASROCK 775DUAL-VSTA board which isnt renowned for its overclocking capabilities

the 450 should be enough to run the system you mentioned.

but if i were to change my graphics card to say an x1950 pro in a few months would i need to change it?

thefishdude · 29 Dec 2006 at 11:14

nope dont think so i have 1950pro based system (see ma sig) and at idle speeds browsing net it only uses 150watts. and i doubt the power usage tripples in games.

ah cheers for that

how do you find out how much power your system is currently using?

mishima · 29 Dec 2006 at 11:16

I would say a 450W+ (don't go for a cheap non branded one!)

If you wana check your system try this PSU Calculator

i have a APC 1500i ups and with the monitoring software installed and it tells me my power consumption. i have a 700psu in mine but thats because i intend to get a large screen and the new ati monster card when it comes out in march time.

cheers for this mate

very nice link although im not so sure if its that accurate or not - i put my current spec in and it goes quite a bit over what my psu is

The calculator is very good - *but* it is a MAXIMUM power usage calculator - it presumes that everything is working flat out at full power... i.e. in 3D game with all hard disks working, CPU at 100% and optical drives going flat out.

Realistically.... that isnt going to happen - but overclocks and extra devices can draw extra power here and there, so a weak PSU will have problems when it nears 100% load.
My PSU is a 350 Watt in the Arctic cooling Silentium case, and it runs the rig in my sig fine
