I intend to have at least a fighting chance of achieving the overclocking figures published at anandtech and legitreviews for the ASUS mobo/OCZ RAM /2.6C cpu (quite often tested instead with a 2.4C) combo. I bought these products specifically for their capabilities, but I am totally new to Overclocking, so I'm not sure if I'll be always running at max levels. I understand it is possible the achieve 260-280FSB=say3.5 GHz from a 2.6C,using these products. Don't know about power or heat yet!

I only putter around the internet and newsgroups, and I'll actualy need to obtain some serious new game(s). I am not sure of the level of cooling and power I'll need. In the case of the psu this means both (power and cooling req'd).


Due to another psus failure, about a year ago, I bought a Powmax LP-8800C psu to use in my current 1.0GHz capable coppermine ASUS CUSL2-C PIII mobo. It is capable of all the connections on my new P4 mobo, but it may be too cheesy !? In my limited understanding I assume that the major reason is its tendancy for power fluctuations which are un-regulated in the psu, because I also assume it is a passive (not active) PFC unit. Do I need to get rid of it? Might it do the job, or is it a mistake to attempt it with these products? I have already yanked and replaced its internal 2-wire 80mm fan with one Stealth 80mm fan wired directly to the PWR_FAN 3-pin on my mobo.

Any opinions on the psu question would be appreciated.

I assume any would be good, but do I have the right power output req'd. Is 300W enough power for this setup, and my intended usage? (Any higher and the price rises. My system will not need any more components than listed, and I don't know if predicting the future of psu requirements is possible?)

Will any of these psu options have sufficient integral cooling for this setup, and my intended usage? (I like the Zalman (option#1) because it has only one fan, and I like the idea of quiet, if that is indeed the case).


my current psu(Powmax LP8800-C) is rated here,

Cliff-notes version:

"Is a 300W power supply enough to do heavy overclocking with a P4C800-E Deluxe, a 2.6C @ real high, an IDE drive, two Raptors in RAID0, two optical drives (soon), two memory modules, a low-end AGP card, two PCI cards and the usual loadout of fans and other stuff?"

I wouldn't bet on it, no. Antec TruePower 430 or Enermax 400-series units are where I'd be starting, if I were you. The Enermaxes have particularly-high 12V amperage ratings and could be worth a look first; they make models with manual fan-speed adjusters too. The Antec TruePowers come with three-year warranties and generally run pretty quietly.
