PC Case & Power Supply
« on: May 04, 2009, 11:43:38 am »
Well, I have reached a point in my system where my video card (ATI 3870X2) is tripping my power supply (Thermaltake 750W) when I am doing something intensive, such as slagging super mutants in Fallout 3.

I'm thinking about a new PS and I'll probably get a new case as well (Thinking of upgrading my mid-tower to a full-tower so my 12" graphics card isn't wedged against my hard drives).  I'm seeing a lot of cases with the PS slot on the bottom now.  Has anyone used one of these?  I'm probably going to need a 1200W-1400W rig to power everything, and that concerns me with the PW fan being low.. will it push enough air to stay cool..

Anyone have any experience to share?

Dang, what you need all that power for?  I've been getting by with 600 w for a while.

When you have 1500 instances of wireshark running you need the juice.  ;D

LOL...

My rig is running an AMD Phenom Quad Core, 4 GB of DDR 1066 RAM, an EIDE DVD burner, 4 SATA hard drives and 2 EIDE hard drives, and that 3870 X2 PCIe 2.0 video card (2 3870 cards on 1 card, with 1 GB of video ram and 4 GPUs).  I think the video card alone is sucking 600w.

You mentioned the card was between the HD's. Could it possibly be a cooling/airflow issue rather then the PS?


Either way though, one can never have a large enough power supply. Never know what you might add later.

Cheap solution too would be to toss out some of those drives and stick in a couple of 1TB SATAs.  That'd reduce the power footprint considerably.

I do want a full tower though... tired of busting my knuckles in that thing.

Hey.. here is a neat tool:

According to this I need about 692W

I'm using a CoolerMaster Stacker 830 case, full tower with a lot of room, big side flow through panel and top & front bay ventilation. Very easy to work on (tool-less), gives a lot of options (reversible front panel door, multifan bracket for the side, etc..)

Power-supply on the bottom (ATX type B?) looks like one of three options for the nearly identical Stacker 831 case.
