Default Amd X2 6400, 600w Psu

Just a thought, is there any reason the PSU in the below link won't work with a 6400 and 8800GT? - COOLER MASTER eXtreme Power RP-600-PCAR ATX from factor 12V V2.01 600W Power Supply 115/ 230 V Safety Nemko, TUV, cUL, CE, BSMI, FCC, CCC - Retail

If there was a problem with the PSU could it cause everything to start up like fans and lights but there is no display at all? I have another thread open with different questions but I figured I would throw this out there and see. I am going to try and acquire another PSU and test it.

Here is the comment on that page that made me wonder...

It looks like it has two 12v rails running 18A

The 6400 says "Voltage 1.35-1.4V" and "Thermal Power 125W"

I'm not sure if two 18A rails will work.

I am running.....

Abit AN9 32X
AMD 64 X2 6400
GeForce 8800GT
2GB 800/6400 RAM.

According to eXtreme PSU Calculator Lite, a 600W PSU is barely capable of powering a system similar to yours, overclocking the CPU to 3.4GHz, bumping the voltage up by .05V, which 4 sticks of DDR2 memory, 2 SATA hard drives, a DVD burner, a Blu-ray drive, 2x80mm fans, a 120mm fan, with a Sound Blaster audio card, 2 USB powered devices, a Firewire powered-device, witht he CPU and PSU running on full load with 30% capacitor aging. So, yes, that PSU is more than enough to power your system.

Infact, assuming that you DON'T overclock your CPU, and DON'T have that many powered external peripherals DON'T run your entire system at full load all the time, with one or two DVD drives and one or two hard drives, you could even run two 8800GTs in SLI.

And two 18A rails is plenty for your 8800GT.

It'll work its got enough power... its got enough Amperage on the 12v rails. - CORSAIR CMPSU-550VX ATX12V V2.2 550W Power Supply 90 - 264 V UL, CUL, CE, CB, FCC Class B, TUV, CCC, C-tick - Retail

better Amperage on the 12v rails

should work fine, Im using an echo star 600 watt to power my amd athlon 6000+ which is only 200 mhz slower then your 6400, and I can overclock it to 3.2 ghz without any issues. (cant go higher then that cuz my cooling isnt good enough) im using 2 gigabytes ddr2 ram, 2 optical drives, and a sataII hard disk. havent put in a vid card yet, but that should be fine for your system, it looks like a good PSU.

I picked up a Corsair 520HX, its great no complaints here at all. So if you're open to suggestions look into that guy.
System sold.

wow why do you need so many fans, you planning on overclocking? lol I have no idea I havent sat down and measured power consumption. Im only running 1 120 mm intake fan, 1 80 mm exhaust, and 2 60 mm exhaust. the 2 60 mm exhaust I dont even need in fact, their their cuz im paranoid. my system idles at 90 degrees f. and my cpu at 80 degrees f. I would say unless your doing some serious overclocking 7 120 mm fans are a bit on the overkill side. 2-3 should do you just fine.

I'm going to be using 4 fan filters so I wanted more intake fans to compensate. I might have to scale it down if it's too much for the PSU. I've had to many heat problems so I am taking off the gloves this time.
