Need a new PSU

I've never really cared about PSU quality too much... but quite frankly the PSU I now have frightens me. It's a super generic (480W POWMAX AG II) that came with a cheap case I bought a while back. I just recently installed a second 7200RPM SATA drive, and a 3100RPM CPU fan with manual speed controller. 2 things now occur randomly. Computer reboots at any given time, and computer reboots whenever I adjust the fan speed with the controller.

My system ... nothing amazing -

AMD Athlon 64 X2 4200 (Toledo)
2 x 1GB PC3200 Ultra DDR
Nvidia 7600 GT (580MHZ core)
1 WD Caviar 250GB 7200RPM (YS)
1 WD Caviar 80GB 7200RPM
MB K8T Neo2 v2.0

Not sure how much my CPU fan matters but it's a 3100RPM fan so I imagine it draws some decent power. System has always been super stable... and even still only has this problem maybe once a day. I can usually game (WoW/EQ2) for hours with no problems. Just starting to get concerned... even if it's not PSU related, I still need a decent one!

Anyway, looking for a PSU that's under $70 and from a reputable name. I read a lot of good things about Corsair, but I don't think I need something that good...

Thanks much!

No worries about the fan, it will be a couple of watts only. For example I found one at newegg called KD1212PTB1-6A, it runs at 3100 rpm, and on the manufacturer's site it says 3.7W. Other models are rated as much as 12W, but you get the idea.

Corsair 650TX, $72.24 after rebate and shipping

Mind you, it's enormous overkill for your current PC. However, between the 650W at $72.24 and the 400W at $61.42 (both after rebate and shipping), I'd very much prefer the 650W because it's reusable in your next PC. I'm hoping you won't keep using a 7600GT for much longer - you're missing a lot of fun with it :(  A 400W PSU won't support a decent video card made this year. For example HD 4850 manufacturers recommend 450W or more.

Thanks for the replies.

Two things about the 7600GT. 1) I went with it only because AGP board was received as a Christmas present and couldn't rightfully ditch it for a PCI-e. 2) It's actually not a bad card! Kills my FireGL softhacked 9700Pro :-) Can run EQ2 on High textures, full view distance, and bloom / lighting on and never get below 40FPS. Can't really complain... of course if I had PCI-e I'd go with a better card... but I typically overclock the 7600GT to about 615MHZ with no problems... and no this has nothing to do with random reboots since I haven't OC it since 178.13 :-)

Anyway, keep the suggestions coming. I appreciate it! Leaning towards a Corsair so far ...

aevm has a good point. I suggested the 400W PSU for your current rig. If you think you may be getting a new system within a year or two, upgrade to the 650TX so you will be able to reuse it in the new system.

I agree with aevm. Corsair psu's are high quality. The 650 watt psu will last you for several future upgrades.

There's a $50 StealthXstream 600W too, if you want. Still overkill for your current system, still reusable if your next PC is not a monster, but not quite as good as the Corsair. It's quiet, and it has an annoying blue light.
