Stop me if you have heard this one before. A couple of our guys were doing some load testing one day on some PSUs and had some fun with some "inexpensive" low end units.

The unit was rated at +3.3V@28A,+5V@34A,+12V@21A

We tested it with the 12V at 18A, the 3.3V at 20A, and the 5V at 10A on our load testers.

Check out the video clip, Why a high-quality PSU is an essential purchase.

On a side note; What do I have to do to get an 8 pin pcie cable for my HX 620?
I sent an email to RamGuy about 2 weeks ago.

Why not name the brand? Is it staged?

Corsair Power Supplies are highly rated here.
We stay away from the $50.00 stuff that destroys the whole computer.
$1,000.00 is a high price for a $50.00 computer supply.

Thanx Bad, I ended up calling them today, so hopefully it won't be to long.
Then again if it takes longer the price of a GTX280 may go down even more.

It would be nice to know what brand the PSU was, but the point was more that cheap PSUs are just that, cheap, and not put together using quality parts or putting out their rated power.

i cant believe i was actually using a cheap psu until 3 weeks ago :o

I doubt it was staged. If they don't name the brand then there are no repercussions. Also, that way they don't focus on one brand but all junk PSUs.

I actually still have and use one, an Aspire 680wt unit. But its in an old computer that only needs about 250wt, so the Aspire isn't being strained at all. I wouldn't trust the Aspire to any computer that makes real demands for power.

I've got an Aspire 500W PSU that I still keep as a spare because it is the same model I had in my old 939 X2 3800+ rig; my cousin has it now and it is still running some two years later. No, I wouldn't run it anywhere near capacity, nor would I buy another, but it isn't as hopeless as its Tier-5 rating implies. It's got some heft to it.

By doing so they brand every unknown or unnamed PSU, as shown in the video, as junk psu. It is advertisment, that is pretty clear and was from the beginning - that's not my problem though. While i think the video is quite entertaining, unlike you, i simply refuse to believe that all cheap psus are junk. That's why i'd like to know the brand.
And what kind of repercussions should there be? If six psus of manufacturer A fail to complete a basic test of manufacturer B, i don't see the problem of saying so.

Check Newegg, you'll find it.

Brand X is any (all?) cheap PSU. The UK magazine, Custom PC has done a couple of wide reviws of PSUs and have always found that cheap PSUs cannot maintain 75% of their rated output and either shutdown or go 'Bang'. You get what you pay for. Worse still, before they go bang, the outputs can go very unstable, above or below rated output.

I have always loved how the power transistor protects the fuse in these types of power supplies by failing first, usually in a very (as in the video) spectacular manner.

Right, so they get the best of both worlds. They piss on all cheap PSUs and don't have to deal with the one brand that they pissed off.

I would like to know the brand as well, but I don't believe that they are obligated to tell me.

I'm sure that all cheap PSUs are not junk, but I would bet at least 80-99% are, depending on how cheap you consider cheap. You won't find me buying a $15-$20 PSU that's for sure. Just because you know the name of this particular one, would that really matter?

Repercussions from whoever has their name on the PSU. Whether the test is valid or not, someone will be fighting back. That usually happens when you take food out of someones mouth. Why bother dealing with the aggravation, especially when you can paint them all with the same brush and avoid any flack.

That's beyond cheap. I'm not thinking about the totally obvious ones. The 60$ price segment for example. Sure, the price helps a little to part junk from brand, but i had expensive brand psus fail on me or people i worked with. I remember buying two enermax PSUs about 8 years ago for roughly 150$. After 3 years the cables were brittle like rotten wood and one of them went off in flames after a total of 4 years. A 500 Watt unit running a Athon XP 2000 with a meager Geforce 2 and a single HDD and DVD-ROM. It looked fantastic. And the smell...hm...

Zorg said:

Me? Not at all. Exposing companies that manufacturer those psus and obviously rate them totally wrong is something that i actually enjoy. Even a no-name company producing junk is concerned about their reputation.

Interesting indeed.

However, while i can never recommend a cheap psu, looking at the video it SEEMS like they MAY be pulling all the power thru a single rail.

Cheap psu's will often have multiple rails, and while u MAY be able to pull 75% spread out over those rails, trying to get that out of a single rail would be a disaster.

As soon as somebody gives advice look at who they are and where they come from. Do they have a financial objective?

Ps. I own a corsair psu and have had multiple cheap psu's fail after a year or 2.

Yea I had a 10% off coupon on the PSU for newegg so I ended up paying $98 for it. Not bad for a retail, single +12v rail, 52A, 650w, 80+ Certified PSU with the good quality that they seem to have been making them with. I couldnt pass it up lol!

Agreed, $15-$20 is beyond cheap, to you and me. I just wanted to clarify that as the price goes down the percentage of garbage PSUs goes up, and that the word cheap is a subjective word that was not quantified. Although you consider a $20 PSU beneath reproach approach, many newbs don't. I have seen posts asking whether their PSU is ok to drive x, and when I look I wonder how they couldn't know better. I read a post from a guy that was pissed off that his $25.00 PSU blew up and he was wondering if the company that sold it to him was responsible for his blown mobo etc. He wouldn't listen to absolutely every poster that said the $25 PSU was junk and that every $25 PSU is junk. He kept going back to the specs and insisting it was a good PSU. Don't get me wrong I'm not saying that, with a good enough sale, you can't get a decent ~400W name brand PSU for $35 because it is possible, just rare. I'm not also saying that you can't get an expensive name brand PSU that is a dud, as you obviously found out, but it is not the norm. And I am certainly not saying that good name brand PSUs can't blow up, because obviously some do. Also, not all expensive PSUs with a "name brand" are really a good name brand, although even those are made better than their low priced counterparts. You can get a good medium duty PSU on sale for $60.00 with a little sale searching, if it was a 650W it would be suspect.

Right we all want to see the see scam artists that prey on the newbs get fried. All I'm saying is that it isn't Corsairs responsibility to do it, and it doesn't negate the test or message in their advertisement. Or really have any impact other than a little joy for us.

I was looking for a review of several cheap PSUs that I saw somewhere but I can't find it. So I will leave you with a test from JonnyGuru. It's one of those PSUs that comes with the case that all the newbs think is such a good deal.

This is the only reference in this entire thread telling me that it is a Raidmax PSU.

Someone needs to sue them for that to occur. And as it seems, no one is willing to risk it. Not even Corsair after they tested the PSUs. That leads to a few rather simple conclusions.

I learned my lesson in the past about being overly cheap with the power supply (took the motherboard with it) but up until last week I figured that it was still ok to somewhat skimp on the power supply. This seemed to hold true until I actually needed the power. For the last 7 months I had been running a 700watt power supply (wont name the brand although I've had 3 others from the same company). This one I happened to get free with a case, from the beginning it didnt seem to be as quality as the previous power supplies from this same company but I tried it anyways. Things ran great until I upgraded my video cards from a single 3850 to two 4850's running cross fire. To make a long story short things ran fine until I enabled crossfire and fired up a game. After about 5 minutes of play the lights in the house dimmed, followed by the lights in the computer, followed by an electrical crackling sound followed by a complete shutdown of the computer. Luckily the power supply seemed to have a thermal protection mode, reset the switch on the back, waited for it to cool down and it then started back up, no damage to the pc or the power supply itself it seems. Ran some tests and it ends up the power supply holds up fine as long as its under normal use but when stressed it seems to overheat causing the 12v rail to drop and the power supply to then go thermal. I quickly replaced it with a Thermaltake Toughpower last week. The first thing I did was try to stress the toughpower and monitoring it the 12v rail never budged an inch. I learned it once in the past and came close to getting a reminder this week.... With the system I have now things could have gotten real ugly. Specs below.
