My PSU blew up. need to buy a new one - Page 4

post #31 of 41
Thread Starter 
Thanks again Chozart.

I have no intention to put any other video card in. but I might add an extra HD/RAM.
I also have some case fans and LEDs of course.

When you say that you don't suppose it can hold 4ghz continously, do you mean I might turn my PC into a bomb again?
What about capacitator aging? I guess 30% is too much. but with a 400W PSU I am very close to the edge aren't I?


How can you even check if your PSU is able to hold your machine?

I am more concerned about temperatures of the CPU that will prevent you from running 4.0GHz 24/7 than about the PSU... TomsHardware tested it with a Zalman 9500, and it ran over 60C if I remember correctly.

I think it is pushing it a little with that PSU. The TEC you choose earlier sounded better to me spec wise (500W, 35A 12V..correct?), or otherwise the Enermax I linked to you (although a bit expensive).

When a PSU is taxed too much by your PC, you'll notice a drop in the 12V rails, random reboots, and/or a really hot PSU....

The temps I'm getting are very good. at 3.8GHz I had my processor running at 48c on full dual prime95 load! on idle it was working on 33c.

The 200MHz shouldn't be to difficult with my Freezer 7 pro. I still have like 10c to play around with, which is a lot!
If for some reason it is too much, then I'll stay at 3.9GHz or so. But I don't want the PSU to be the blocking factor.

By the way, I'm not even sure I can reach 4ghz with my motherboard. I couldn't post at anything bigger than 3.9GHz before. and even then I had immediate reboots at POST screen. I think this was due to my PSU failing though.

I also asked for help in an Israeli forum, asking whether I should get the HEC PSU or the Enermax you offered. I was told that I'd be better off with a 400w Enermax Liberty. In that case, I'd prefer having the 400w FSP which is half it's price. But why would a Liberty 400w be better than the Noisetaker 485w you offered?

The Liberty is the high-end range from Enermax, and indeed high quality. However, those noisetakers are not too shabby either, and you'll have the advantage of the additional power.

If you want pure quality, the Enermax Liberty is your choice. If you want the additional power, then the Noisetaker (also good quality).

The FSP is also decent, but not as solid as the Liberty.

It's a tough one

How much for the Liberty there?

Indeed a tough one.
I just don't really see, according to the specs, where the liberty outperforms the noisetaker?

Liberty 400w - 450
Noisetaker 485w - 450
FSP 400w - 225

The only thing where the Liberty is better is that it's the top-line. Thus, higher quality components (more expensive). The drop in power due to aging will not be as much as the Noisetaker. However, the Noisetaker is still a good unit for the money, and the drop in performance will not be that bad when it gets older that it will drop below the Liberty.

Sidenote: is there a slightly heavier version of that FSP? Say, 500W with more than 30A on the 12V rails? And if so, maybe fore 350?

I understand.

I wish there was a heavier version. for some reason even the 450w FSP model costs around 450-500!

The incerdibely low price for the 400w is only in one store(everywhere else it costs around 350). A bit odd if you ask me, but it seems that many people recommend that model due to it's fantanstic price(and since it's FSP..)

IT's the best bang for the buck.

I do think that it will handle your rig. Esp. since your video card is not that power hungry.

Plus, how ofte will your rig be maxed out, requiring the full power delivered by the PSU? Generally not.

It's indeed the best bang for my buck.
I am doing a lot of video encoding/filtering, which might max my machine(only CPU?) pretty often.

However, in two years or so, maxing out my system might result with the PSU dying/exploding again. I may save 200-300(my currency) now, but if my PSU will die eventually, and in addition it might take more components with it, I will end up paying more.

I'm sure you can see why I have problems deciding...

Personally, I would indeed see if you can scrape together some more money and go for the bit more powerful one.
