My PSU blew up. need to buy a new one - Page 3

post #21 of 41
I edited my post while you posted. What is your budget limit? That Enermax is a great deal I think.

Not sure... I just put in the parts, and after entering each part, I let it calculate the total. What's your breakdown? And again, I did not adjust anything.. just straight loading the page and go for it.

I also edited my post. What I said there was that I prefer not to exceed 350-400 in my currency.
If it is really necessary then I will spend the extra cash for that enermax you offered(450 my currency).

Problem is, I want to be sure that if I'm going to do that, then this PSU will be able to hold my machine for atleast 3 years. 485W still seems like too little for me. I'm still getting high numbers in the calculation.

And I'm sorry... but what do you mean by breakdown?

Earlier I posted Wattage per part (like CPU, RAM, etc).

Trust me, that Enermax will be just fine. Remember that TomsHardware used a PSU in that range..

Also, 32A on the 12V rails is more than several 500w+ PSUs. The 580W Hiper for example only delivers 30A. Thus, even though the Hiper delivers more Watts, I'd still pick the Enermax.

That Enermax will cost about $76 here, so 450 for you is a good deal.

Don't run blindly on that calculator. It's an indication and a guideline...and no more than that. I generally don't use it too much, and if I do it's to estimate power use per part...

I apologize for going over and over the same issue, but I want to make a smart purchase this time.
Did you take into consideration all the parts? including HDs and stuff like that? I also took into account the fans, leds in my system, firewire device, and a potential upgrade of an extra HD.
Maybe that's what making the difference.

I'm also trying to see why that enermax is better than a 500w hec, which delivers 35A on the 12v rail?

Hec is decent. It's not enermax, but it shouldn't blow up or something I guess. and it costs 350.

about tomshardware. Well, I don't expect the new PSU to give me problems at first. Like I said, I only worry about what will happen a couple years from new.

I don't know HEC as a brand... and since I *had* two PSUs that did fail (one indeed blowing up) I am hesitant to recommend any PSU of a generic or not well-known brand.

In my case, the brand was Coolmax, and it was a 550W unit with about 36A on the 12V rails. The first one just failed... automatically rebooting my rig again and again (11.4V on the 12V rails does that ). Then, RMA, and got a new one.. That one went out with a bang and a lot of sparks. Goodbye PSU and motherboard(!).

Thus, my advice, really stick to the known brands. If HEC is a reputable brand over there (maybe it's just a European brand I don't know about), then by all means get it. But again, I'd stick with known brands.

The Enermax is better in my opinion, since Enermax is a brand known for making excellent PSUs. I'd rather get a brand like that, even if specs are lower, than one that has better specs, but from some unknown brand.

HEC is a known brand here. I think it is located in germany and that's why you don't know it.

It is not as good as enermax. Yet it is reputable, and I never heard anyone feeling uncomfortable with buying it.

It seems that the enermax you offered gives 80% efficiency on 30-100% utilization. The HEC gives around 72%. less when idle(like 60% from what I saw).

The difference in money spent now, might not matter much since I will probably pay more for my electricity bill. Not sure if this is something to take in mind or no though.

The HEC PSU price is 334, while the enermax is 450.

If you trust the HEC brand, then it definately seems like a good deal. Your energy bill might be a little higher, but not by a whole lot

Good luck

I was wondering, will this be able to hold my system for a long period of time(3 years) and overclocked to 4ghz?

It's only 400w so I'm worried, but it has 29A at peak on both rails. And the best part - it costs exactly half than the enermax 485w.

http://www.fsp-group.com.tw/english/...d=52&proid=191

What do you guys think? Take into consideration my overclock and the fact that this product will age and lose some power.

FSP is a good brand. Also, it's 29A max load (peak is a little higher most likely), which is good enough for your rig.

I'd say it should be able to do the job, but I am not sure it will do so at 4.0GHz continually. also, I don't know what cooling you have, but 4.0GHz will result in one hot CPU.

The CPU alone with draw nearly 15A when you run it at 4.0GHz and 1.6V. that's half the total current on that CPU. However, you don't have any other parts that are very power hungry, and based on that, you should be fine. Just don't suddenly stick an X1900XT or something in that rig, because that'll be too much

Yeah, that FSP should do the job
