300Mhz power supply ok for P4?

Only if a 200MHz is enough to power a PIII. Personally I like a 400MegaHurtz or higher for that extra punch.

That's the fastest power supply I've seen!!! Are you going to overclock the power supply? 😀

300 Watts should be fine.

Man you guys aint right. I'm trying very hard not to laugh here but.😀
 
That's a waste of money. It would be fine with a 200watt power supply. People constantly buy overpowered PSes and it's silly. You'll find many major OEMs that ship their P4 (top of the line) with only a 200-250 watt power supply. I don't want to type in the whole explanation of why you don't need a 400watter you can read this guide for instructions on figuring out how much power you will need based on what components you have.

Seriously, I wouldn't take too much stock in this. Power supplies aren't measured in megahertz and he also spelled megahertz wrong. One thing that I would recommend is getting a good quality one. In this case, the rated Watts is less important than the quality (brand name) for reasons outlined clearly in the above linked article.
 
Geekish Thoughts was making a joke due to fern3's mixup of watts and mhz. As for buying overpowered power supplies, most cases these days come with a 300 watt power supply (or at least one that pretends to be so)-so there's no added cost in buying a 300 vs a 200 if that's what the case you like came with. I'm putting together a new P4 system right now, and the case I bought came with a 300, which I hope is enough. I figure so. However, if I bought the case and motherboard seperately, I might have bought a 350 or a 400 watt supply for the added safety. But, I'm pretty sure a 300 watt will work, so I'll use the one that came with the case. (It is marked P4 ready.)

I dunno......300MHz would probably limit the speed of the P4. After all, if the PS can only supply 300MHz to the 2000MHz processor, where is the other 1700MHz gonna come from? 😉

Sorry. I couldn't resist. 😱 Power supplies are measured in watts, not MHz (don't worry, it's an honest mistake). 300 watts should be perfect for your system.

And 7757524, you may be technically correct on your assesment of power supplies, but I challenge you to run a decked out system on just a 200 watt power supply. What happens when you pop in a power-hungry Athlon? Literally hundreds of qualified people have recommended people to buy a nice, big, high quality power supply... Why? So that their readers/customers/friends have the choice to upgrade to a broader choice of platforms, so that they are not held back from updgrading their peripherals, and that their systems are 100% stable.

Sure, you could run a P4 on that 200 watt platform, but is it ideal? How much is $20 going to matter when you're upgrading to a more powerful power supply? You could also buy a microATX motherboard for a P4, but why would you? To save a couple of bucks? I'm gonna stick to my guns on this one...a power supply is not a place to save money. It is foolhardy not to buy at least a 300 watt power supply these days. Anything less is simply...uncivilized.
 
When you get a ps(power supply) Make it an antec TRUE Power power supply! They are the best and quietest power supply.I got a 430 watt True power for 79 shipped i belive but if you go lower im not sure what the smallest True Power power supply is they will be cheaper!

Yes. I run a 300w HEC 300 AR-T w/ Panaflo L1A fan in my 2.4GHz rig. No problems.
 
Regarding the comment about running a "decked out" system on a 200watt...of course you need more ifyou're decking it out. Like I said you have to figure out how much each rail is going to need and then apply that to the power supply. The overall wattage of a power supply is meaningless if you have 20 hard drives and all of your draw is on your 12v rail. This is outlined in that article I linked to (and wrote)
 
so you people think an Antec PP303X 300watt PS will be enough for a P4 1.6@2.133 on an Asus p4s333? my friend has an SX830 case and he wants to upgrade his duron 750 system for as cheap as possible, so i'm plan on just doing a ram/cpu/mobo swap.
 
absolutely enough. If fact, 200watts would be enough. 300 gives you room to ad lots of stuff though. That brand is good and when they say 300watts they're actually using the combined 3.3 and 5v so it's REALLY 300watts.

That's better than most peoples' system here. If that can run on a 200W PS, what could you possible put in a single CPU system to overwork a quality 300W? I wouldn't recommend a 200W to anybody, there is no reason to waste money on anything over a 300W.

A higher rated PSU *IS NOT A WASTE HERE PEOPLE". The only thing that differs between a 300watt and a 400watt is the amount of molex connectors. Higher Watt PSU= more power connectors!! If your using a bunch of HD's/optical devices then by all means get a higher rated PSU, if your not, 300 is perfect. I'd go for a higher rated PSU, better safe than sorry. You never know when you'll end up with an add-in controller and more HD's or whatnot.

ummm....sure. Go to any major OEM's site and look at their configs. You'll see that their athlon systems (what little they carry) have 250watt power supplies. There's no difference. Since I got my nice northwood I've moved my athlon xp into my old case with a 250 watter generic which is a 200watt really and it's rock solid. I would STRONGLY suggest that you read the article I linked as you don't seem to understand the way it works.

That's funny. Both enermax and antec's 300watt power supplies have the same ammount of connectors as their 450watters. And that's a lot of connectors. It's just the generic ones that don't and they pose other risks as outlined in that article.

Your esteemed link is broken.

I like how many components you have in your P4 system... One hard drive, one CD-ROM, no zip drive, no hard drive controller...

And if you want to talk "feats of engineering" (a.k.a. shoehorning a rig into a case with a small power supply), then I'll tell you about my PIII system that I have.

I have a 600EBMHz PIII with 384MB of RAM, a 16x DVD-ROM, a 12x CD-RW, 2 hard drives, a floppy, AGP videocard (GeForce 3), PCI modem, PCI sound card, and a PCI NIC all running in a case with no fans (save for one on the power supply) and a 145W power supply that was made in May of 1997. I understand that the 145W rating on my power supply is the maximum that it can provide...and that the average power draw is not that high. That's why my system runs. But I can't vouch for its stability (then again, it is running on a Via chipset 😉)

Anyone can cram a system into a case with a small power supply. But is it a good idea? I think not. How much of a rip off is it to spend $20 more to get a high quality power supply? Can anyone here besides 7757524 tell me that they think spending money on a high quality 300W power supply is a bad idea? Furthermore, how many people here regret spending money on their high quality power supply?

I think that my 380W Antec TruePower power supply was a steal at $70... I get good, clean power, two temperature regulated fans, plenty of molex connectors, and extra molex connectors for my case fans (which are also temp. controlled via the power supply).

And as for those Compaq and Gateway computers with small power supplies...I think its a rip off. When I drop thousands on a computer, I want a power supply that can take the abuse of overclocking, and have room for future upgrades. Did you take a look at the Falcon NW and Alienware computers? How many watts did their power supplies have? Now tell me, which computers do you think were better....
 
That link works fine. Maybe it was down for a minute when you tried. Try again. After you read it you might have a better understanding of how a PS works. Good luck.

And about 100watts. I personally like having a smaller PSU just to keep PC heat and electric bills down.

Heat, yeah.

Power bills? You'll only use as much as your components draw.
