Is a Fortron 350 watt ps enough for overclocking an AMD cpu/

[gplracer]

I got a Fortron 350 watt ps that I just purchased. Will it be enough to overclock an AMD cpu to a high fsb like 240mhz? I also currently have a channel well 420 power supply. Would this power supply be enough> It is running an AMD system now with a two hard drives, cd writer, dvd player, floppy, tv tuner, and a speed of 215x11=2365mhz. I cannot get a higher fsb so I just wondered if the ps could be the culpret. My 12v rail sometimes goes down to 11.80.

Your Fortron will be fine. 11.80 on the +12 rail is well within spec.

I also have the Channel Well unit mentioned, and it's unlikely to be the problem. Mine has proven to be a rock as far as stability goes, but if you're worried about the 12v I'd measure it with a meter to be sure it's really fluctuating as much as mbm/bios says.

In terms of capability, I would put the CWT 420w and older Fortron 350w about even. Perhaps a slight edge to the CWT when compared to the newer Fortron 350 with 120mm fan.

If its the FSP350-60PN it spits out 16a on the 12vline, should be fine from what ive read

That is the power supply! What about the Channel Well ps?

It has 18A on the +12v line. Is that accurate?

That's what mine says... there is an older non-P4 version with only 12A@12v and higher 5v and 3.3v lines, but thankfully you don't have that one ;)

I should mention, my system doesn't do much to hit the 12v rail as the CPU is run off the 5v; but I've heard of these running dual chips and overclocked P4's reasonably well. A multimeter will let you know for sure if the 12v is sagging enough to be a worry, but 11.8 isn't out of spec for these. I am just now working on overclocking my Barton, but the PSU is still laughing at the load so far.

Edit - just reverified my voltages at 2260 (205x11), and am getting 5.04v load on the PSU. It is doing better than it was on the old overclocked Duron 1300 @ 1450 when it measured 5.03 load. Fluctuation on the 5v is still only .03v (goes to 5.07 no load) - well within tolerance.

Edit #2 - now at 2310 with voltages unchanged from 2260. Having minor onboard video glitches now with memory down at 166 - may not be able to see the Barton's limits without better mem and that Radeon I keep putting off buying, but will try for 215x11 on Friday.

I like my Fortron Aurora 350w. The adjustable blue LED 120mm fan kicks ass. :D

Your current PSU should do the job alright. If you're looking for something to get you to a higher FSB, you might want to look somewhere other than the power supply. FSB is much more (not entirely, but mostly) dependent on your motherboard, RAM, processor, and cooling if it's locked.

If my 300w Fortron can get me there your 350w should be fine. :)

Susquehannock nice overclock! Are you using one power supply or two? Thanks!!!

[jlin453]

My specs are below with a Fortron fsp350

measuring my 12V rails, I get 11.5-11.6V but everything is stable.

Two ... one in each system. ;)
Right now the Soltek is running at 210x12=2520ghz.

Some even use these exact PSU to power loaded dual CPU
rigs too.

I'm currently testing mine @ 2.4 and the 12v is dipping a little low (11.7-11.6). This model is the one Tom's rated for 450w in their 2002 roundup of PSU's.
