Fortron Source FSP-300W enough for P4 3.3ghz?

[Naruto]

My setup:

P4 3.3ghz (overclock)
Abit IS7-E
1 7.2k rpm hard drive
1 dvd-rw
1 agp card (does not require external power source)
1 wifi pci card
3 case fans set at 5 or 7V

This is the power supply in question Link. Also I might consider the Enlight 360W. Which should I get?

no if your overclocking that much your going to max out the 12volt rail on that powersupply. I reccomend going with some more in the 400watt area. my fave would be the antec trupower 430

You sure. I heard someone took his P4 to 3.5 on this PSU.

Just spend 20 bucks more for fortron 400 or something by Antec, Sparkle, Thermaltake 480 which all have 400 watts or more if you want to have stability and easy in the future esp with the new AGP videocards with 2 molex coming around.

I think that psu will do it. I have the FSP-350W and is a pretty amazing psu. I know people who have the Fortron 530W and the 350W and they can't tell the difference.

I have a 250watt SFF system, and my P4 2.4C is at 3.2 ghz. I also have in this SFF a 9800 pro, 2 sticks of 512 mb PC3200 ram, one 80 gig 7.2k rpm 8mb cache HD, Fortissimo III 7.1 sound card, one DVD-RW Drive, and one case fan. So it should be fine with 300watts.

I run a P4 2.53 at 3.5 with absolute stability for MPEG encoding using a Zalman 300A-APF. My video card is a Matrox G550 which I imagine draws a lot less than a gaming card, so I would think the latter may be the more important issue.

It would be nice to see a bit more than 15A on the +12V rail, but it should work OK for you.

Unlike cheapo power supplies, the Fortron line is conservatively rated, and have a very large peak momentary load capacity. Heavily overclocked systems are very touchy about startup voltage, any sag at all will cause boot failure at the limit... So, if you don't demand that last extra mhz, the 300w Fortron will do fine. If you do, then step up to something stouter- their 400w model will run damned near anything, and a 350w model seems like a good compromise...

The price difference going to a 350w isn't much, but going to 400w gets expensive...

Bear in mind that Sparkle is the same thing- the sparkle fsp350-pn is $5 less than the same fortron model at newegg, for some reason... if the model number of a sparkle is the same as that of a fortron, they're identical...

Difference will be more apparent when under load..

From Stardust-

"Difference will be more apparent when under load.."

Not at all. So long as the current draw from the system is less than the actual max continuous output of the psu, there won't be any difference- the internal circuitry will hold the voltages at the preset levels right up to max output, plus or minus a few hundredths of a volt. At least that's true with a high quality unit, like a Fortron.

As I said earlier, the very large momentary current spike at boot can exceed the max momentary output of the psu, causing voltages to sag momentarily, leading to boot failure in heavily loaded or touchy overclocked systems. Think about it-- everything fires up at once, including the drive motors, chokes, capacitors- the current inrush can be much higher than the actual operating current, and is the reason that psu failure usually occurs at boot... Wham! Poof! What IS that smell?

Yes it is. I'm talking about people who have DMM's and test their rails at the molex and on the mb.

Go for it.
