I'm overclocking a little bit for fun (albeit very careful fun) and I'm hitting a limit that I don't think I should quite be at. I don't believe I'm overheating (51-54 deg C or so under full load, 30ish deg C case), and I don't think I'm pushing the memory too far--it's DDR400 with stock speed of 2.5-3-3-8 that's autoclocked by the Asus board to DDR266 at 2.5-4-4-8. So that leaves the power supply not being able to supply enough power. So here's the system:

-Xaser III case with 2 Sunon Ultra high 80mm fans and 4 80mm Thermaltake fans (the ones that come with the case)
-120mm Panaflo high speed fan (115 CFM) that's not running full speed (hooked to a fan controller)
-eVGA Geforce 6800GT slightly overclocked
-Pentium 3.2E Ghz (running at 3.64Ghz currently)
-Sound Blaster Sound Card (older one)
-2 GBs of 2x512MB DDR400 (dual channel declocked to DDR266 automatically)
-Spark 7+ cooler (for the copper base)
-Thermaltake Silent PurePower PS that claims a MAX power of 420 watts

So, am I simply pushing my power supply to the brink? Or is there another problem here? Oh, and all parts are sound. I can reliably overclock to about 3.57 or 3.6Ghz stable. It's only when I go to 3.64Ghz or above that I start having stability problems. The FSB

RAM ratio is 3:2. FSB is at 228 and RAM is at 152 Mhz (DDR304).

Thanks in advance for the help.
