Currently, I have an old ATI HD 2400 Pro card which is now really struggling to keep up with modern games, so I think its time for a slight upgrade. I'm planning to get the XFX 9600GT Standard Edition (see details).
What's holding me back right now is that I'm unsure whether my PSU is up to the task. Its an ASUS 350W PSU with max rated output of 400W.
The maximum output of the two +12V rails is 205W and 19A (+12V1 has 14A and +12V2 has 16A, but the total combined output is 19A).
My other specs are:
Intel Pentium dual-core E2160 slightly OC'ed at 2.2GHz, 2GB DDR2 667MHz RAM, ASUS P5B-MX/WiFi-AP mobo, 2 HDs (WD 640GB + Seagate 250GB) and an LG DVD Burner.
The detailed PSU requirements aren't given, though 400W is recommended, I think it just might be possible to pull it off with this (I know someone who's running a 9800GTX+ with an Antec 400W PSU so this should be pretty easy!).
I saw the requirements for the Inno3D 9600GT, and it says a minimum of 30A is required on the +12V rail (isn't that a tad too much??).
So I need to know, will this work?
Thanks in advance!
P.S. The PSU also doesn't have a PCIe connector, but I do have 2 free peripheral connectors so I can just use a Molex to PCIe connector to get around this problem
The main load in a modern pc is on the 12V line. Only hdds, optical drives and some mobo parts use the other lines, but even those parts draw most of their power from the 12V line.
Your PSU seems to be of an older desing with rather strong 3.3 and 5V lines compared to the 12V lines. If you look at a brand new psu, something like 95% (or more) of the rated maximum can be delivered through the 12V rail(s).
I think I'll go for it. Get the 9600GT and see how it goes...the worst that can happen is that it'll be unstable, right? Assuming it won't fry any components, I'll give it a shot, and if doesn't turn out good then I'll get a new PSU.
