Proving you don't need a huge PSU to run a Hi-End System

Recommended Posts

[quote name='TTPete' post='690872' date='May 24 2007, 01:39 PM']You can get a 4 cylinder car to run at 100MPH at 6000RPM or you could get a V8 and be at 3000RPM doing the same speed. I would put my money on the V8 lasting a lot longer as long as long as its a good quality engine...[/quote]
Well, I think the car analogy isn't really very applicable when you get into specifics, but I do see what you're saying.

The thing you're missing though is that if you buy double the power, you pay double the price (maybe more). So yeah it's going to last longer, but you're also out twice as much cash. Even if you're on a rather "unlimited" budget, it's still dumb to spend more than you need to. And it's been my experience that the longer you save your money, the more it will buy for you (watts, mhz, megabytes... whatever the case may be). So even if the smaller one does die, you can buy another and still be out the same money, but the second time you buy, you'll probably get more for the money.

Also, the other thing that comes to mind is the life expectancy of computer parts. I've had more than my share of PCs cross my path, and I have seen motherboards go, fans die, cards stop showing up at POST, but generally speaking, I've found that most PC parts last a lot longer than I've ever needed them to. If you were talking about the difference between a PSU lasting 2 years and 4 years, then yeah it might be worth it. But since most of my PSUs have lasted much longer than I've needed them to, I don't really worry about "wearing them out". I'm pretty sure the PSU from my P3 500 rig is still kicking in a friend's system somewhere...

Also, while I do understand the analogy, I'm not 100% sure I believe that half the load will double the lifespan. But again, the point of this thread is to educate those who think their rigs really -require- this much power.

I decided to stop being so cheap. So I bought what I have now. :)

[quote]Even if you have a powerful PSU, but have a watt meter, I'd be interested to see any measurements[/quote]

I missed this comment earlier other wise I would have posted something sooner.

The mobo in my office PC died awhile back and I was forced to upgrade everything to get up and running again (replacing a socket 754/agp board would have been a waste of money)

I wouldn't call my new PC "High End" but it's quite capable of playing games and is certainly overkill for an office PC.

The Specs:

Asus P5B Deluxe
C2D E6420
2x1Gig Muskin DDR2-800
Sapphire X1950XT 256mb
Audigy 2 ZS
WD 160gb sataII
Seagate 250gb sataII
PC P&C Silencer 750

The PC and more detail on specs and setup:

SMP folding using VmWare and ubuntu Feisty

SMP folding, 3Dmark05 and Mediaplayer (to throw the sound card into the mix)

I don't know what guys are sticking in these "high end" PCs that require 1000watt PSUs but it seems like overkill to me. B:)

Here is a nice writeup on the first system I linked to

[url="http://www.overclockers.com/articles1452/"]How Much Power Do You Really Need For Your PC? Yet Another Experiment[/url]

I need to do some hunting around for some more examples soon.
I also need to update the Recommended PSUs list. Edited by jammin

There is a rather good discussion at SPCR regarding the article above.

Take a look at it [url="http://www.silentpcreview.com/forums/viewtopic.php?t=41127"]HERE[/url].

It brings up some issues of whether it is right to be recommending lower powered PSUs to those with less system building experience (who are therefore more likely to subject their PSU to higher temperatures).

I personally try and bring context into play when making any personal recommendations, which is why I encourage people to ask in the forums.

This one is relatively accurate for calculating the peak power you'll ever need.

That's every single component running at max...I honestly can't think of any time you'd ever be able to achieve that. :P

I thought it was high too. It is cool that it calculates overclocked CPUs.

Yep, voltage, stepping, and everything. Neato. :)

It's nowhere near accurate... I just put my current rig specs in and it recommends a 1010 W psu... I have a 510 W psu, and I've measure my system and it uses 408 W DC at full load on cpu and gpus

so it's basically recommending the worst manufacturers 1010 W psu, because maybe with TWICE the wattage I really need, it can supply it at all temperatures lol

that said, it's probably the most comprehensive psu calculator on the web, and I guess over estimation is better than under :thumbs-up:

I think I probably us about 300 or so while folding or intense gaming after looking at some other peoples usage with similar systems.

Does anyone have any links to the watt meters you plug in the wall?
