That's what I have friends in the industry for. Whatever I don't know, I ask my PSU expert. And yet, he agrees with me.

All I know is what I've already said.

As for your list - none of those things are likely based on my experience. You have a better chance of your components dying on their own.
if u think so
then its my sincere appeal that u keep ur adive to urself...coz u dont want to be blamed by the op if his psu takes his components with it.......

The info should be on the sticker, but it's not on the product page, so there's no way of knowing that the PSU is actually rated for. Next to the ampere rating of the 12V rails, there should be a mention of the max power the 12V source can deliver.
See this for example: http://images17.newegg.com/is/image/...20-S04?$S640W$
Under the table with the ampere ratings, there is a line that says +12V1, +12V2, +12V3, +12V4 max. load: 45A -- that's how you know how much power you actually have available. The individual ampere rating for each rail are where the OCP is calibrated, meaning if you try drawing more than the rated amperage for that one rail, the PSU is set to shut down harmlessly.
But the stickers on cheap junkers like that "680W" Chiefmax and the one you linked to at Micro Center tend to lie or make the numbers look prettier.
Compare that with the sticker on the Sunbeam 680W unit that other guy mentioned (you'll have to click on the pictures to find it). It bears no mention of the actual max load at 12V. It should, but it doesn't. It just says a combined rating for all rails. This is HIGHLY suspicious and says nothing about the PSU's actual capability. But in all likelihood, it can't deliver more than 350-400W, it has horrible ripple suppression, horrible efficiency, and it has a 1-year life span before it dies catastrophically.
Thank you for taking your time to write this very informative post. the technicalities of the PSU are the details i've neglected most in my career as a build-it-yourself hobbiest, as you can tell. your time explaining this has informed me and was by no means in vain.

there are still technicalities and vague parts that i don't understand enough to argue with or understand substantially, but my general drift is that you have a slight bias against bargain brands and dismiss them wholly without exception, so I'll have to "take your word" when it comes to the 430w antec power supply recommendation. again, thank you for your explanation and advice. Track thank you too, i think there's a middle ground somewhere...

what do you guys think of this?

just see ur link psu's 12v ampearage its too low for a gud 600 watt unit....for eg my 600 watt has 48 amps on 12 v ral and urs barely has 35 amps(u cant add the 2 rails directly)....

It isn't an undeserved bias. I do agree sometimes people go overboard in dismissing borderline power supplies, or assume that everything is as bad as a Leadman or Linkworld. But once you see how prevalent overrating is (even among popular brands like CoolerMaster and Thermaltake, and recently Corsair on their low end) and see some of the crap foisted on consumers, well...






This is sold as a 680W power supply, but will consistently fail catastrophically due to multiple part failures somewhere in the 250-300W range, usually sending voltage spikes and current surges downstream.

It has a voltage selection switch... this PSU's design is at least 4 years old and predates current ATX PSU specs.

I bet this is a 400w PSU at very best.

Avoid it like the plague.

If you aren't then I really must pity you the day when you put something like the LPSW in a system of yours and end up shortly thereafter with a completely dead computer. And I pity any "customers" of your "business" who end up with such garbage in their systems. As for your expert friend, try talking to real experts. For instance, Jonny Gerow who has been product manager for several large power supply companies, started his own review site and became the biggest name in power supply reviews. Also his protege, Jeremy Schrag. Go to JonnyGURU.com/forums and try telling them what you're saying here.

After all, where better to troll PSU buffs than their mecca, am I right?
So you actually believe that there is a chance that I am just here for the sole purpose of spouting false information for the probable prospect of misleading people and having fun playing this game?



You literally couldn't prove my point any better than you just have.

But yes, if I was a troll, I would passively continue to dispute unprovable claims while slowly seeping in false information to create a counterargument based on completely circumstantial evidence.
I am impressed with your inference, however. I will give you a B+ for your interpretation of the characteristic of a troll.

I am so sorry that you pity my customers, sir.
I will have to tell the army of your criticism of me.

You have your experts, I have mine. Yours have websites, mine do not.

I understand fully that you have to squash any bit of indifference to your way of thought if you've based so much of your life on it..

But this pompous attitude is not going to serve anyone on OCN.

You are here to save people from the slim chance of having to replace a component. I am here to save people from overspending on a component that does give them any computing benefit.

Let's just leave it at that.

Brands you need to just completely skip over:

Apevia, Sunbeam, Linkworld, Broadway, Diablotek, Logisys, Athena, Coolmax.

Also most of Raidmax, though they have one or two half-decent units at higher wattages.

Okay, I am going to PM you because this could get long.

But yes, yes, we understand the graphs.

How does this have anything to do with the question -
"Will this PSU power my rig for two years until I upgrade?"

Right. As long as you want to waste your money.

Not really worth it.

It's like building a Lamborghini and using golf cart wheels. Who the hell does it?

Seriously though, for the sake of an extra ~50 bucks, you can rest assured that your PSU will never experience any power failures or take anything with it if it ever does die.
