Well, I would still like to know what PSU you ended up with, uilymmot.

Me too as per my post before yours TC!

I am as you know all for a bit of leeway with some people doing some strange or funny things but am just a little "taken aback' by this thread to be honest if it weren't so time wasting it would be funny and not in a hilarious manner.

If he didn't blow up his PSU, then his original post would still apply. He bought a new one when that happened, and now I'm worried that he may have stuck his parents with a PSU that should be avoided.

In the end i got a Cooler Master Silent Pro Gold 550W... probably overkill but, at least it works

Oh. They (or you) paid a lot more than had to be paid, but at least it's not a bad PSU. You're right too that it's overkill; it's major overkill, especially for a computer that doesn't have a video card. Even if it had one, you'd need to put the GTX Titan in their to make this PSU worth the purchase.

Even then...

Yes well as you say TC even then.....

TwoCables · Jun 2, 2013

I guess I'm just relieved that it's a safe PSU even though it cost a lot more money than needed to be spent.

I'm sorry, but this is not true. There are 80+ Certified PSUs that are utter garbage and should be avoided.

Can you make some examples? All 80+ I got (and I got a lot) were flawless regardless of brand (apart from some lemons that were dead from the start, but that's normal with anything). And mind me that I try to put the cheaper ones I can find (while still 80+), as I still like to have a decent profit on the shop's own "quality" builds.
Cheapo builds get crappy PSUs I scavenge from the pallets of old company PCs we buy from time to time. And usually Linux Mint.

Was the point of this thread telling everybody how you blew up your old PSU by jiggering around with it and a screwdriver? If not, then I think you missed the point of posting in a forum and asking for advice.

It seems like he was using the screwdriver on the mobo pins of the power button, which is a way to power it on without placing there a button. I still prefer to avoid these things, but i's not wrong.
And was asking why everything didn't power up.
Sounds like a reasonable question to me, although not really well-written.

Just from Newegg alone, here are some of the 80+ Certified PSUs (from White to Platinum, sorted by price Lowest to Highest) that I would never recommend. This list is not complete due to not being a complete PSU expert. I only know what I know, and I stick to what I know.

This list could probably be a lot longer because I left out a few dozen because I'm just not 100% sure on them yet. So if you're following along on Newegg and you're noticing that there are some that are left out that look questionable even to you, then it's because I still don't know about them yet. Of course, most of the PSUs I left out are recommendable. If I were to make a list of "I don't know" PSUs, "Questionable" PSUs, and "Recommended" PSUs, then I'd be here for another hour. So just because it's not listed here, it doesn't mean that it's recommendable. Another thing to know is that just because a PSU is recommendable, it doesn't mean that you can't get a better one for about the same price or less! The world of PSUs is very convoluted.

Another thing I should mention is that I really wanted to include most of OCZ's PSUs, but I'm just not 100% sure if a true PSU expert would include them on a list such as this one. I mean, I really wanted to, especially the ones that have a name that makes them sound halfway decent, but I just don't know what a true PSU expert would say about including them on a list like this.

I also wanted to include many of Silverstone's PSUs, but I'm not sure what's good or bad when it comes to their PSUs. I don't know what it is about Silverstone's PSUs, but I just don't pay much attention to them.

So anyway, this is just from Newegg's inventory alone. As you can see, the 80+ Certification doesn't mean anything to me.

The stats:

There are 61 PSUs that I decided to list (there are many more that I could have listed, but I wasn't sure of them)
11 of them are White
41 of them are Bronze
8 of them are Gold
1 of them is Platinum (or "Platium" lol)

So as you can see, the 80+ Certification doesn't mean much at all. It's just a marketing trick. What's more important in a PSU is its internal build quality, and just because a PSU has a good 80+ Certification, it doesn't mean that it has a good internal build quality or that it has good capacitors. There used to be a Gold-rated PSU on the market that was so bad that it destroyed the testing equipment that was being used by the reviewer!

Here is an incomplete list of recommendable PSUs. It's important to note that not all of these PSUs are the best one you can get for your money. Some of them are just there in case there aren't any better PSUs available, so the point is: these are all safe to buy:

well yea... the power supply seemed to be defective as in really defective... when I bridged the pins the 4th time the power supply just blew up, literally, thanks for all your help here

I don't think that was what he was doing. If it was, he didn't do it right. Making a PSU blow up is NOT the right way to do anything.

@ TwoCables: I've only heard positive things about SilverStone power supplies. You might look into them and see if they are decent or not.

Well, I'm not surprised that this PSU blew up so easily...

It's better that it blew up now rather than slowly causing more and more strange problems over the next year or two.

Well the thing is, I know that there are some very high-end Silverstone PSUs and others that are not so good, but I just haven't kept up with them to really learn what they are. I still don't know why I haven't!

If I had any brains, then I would start studying this to get started:

OK, I'm not sure about all of their lines, but I seem to remember good things about the Strider series. Silverstone has always made quality stuff as far as I know, but like any other company, they have their "value" lines as well.

Blowing up (small bang and/or a bit of acid smoke) a crappy PSU isn't so uncommon, happens here around once per 4-5 months (more when we buy old hardware by the pallet). Closer inspection (after the offending PSU is left overnight in a bucket of salty water to make sure it's no more electrically dangerous nor burning) usually reveals literally blown (cheap) capacitors or bad soldering and burned stuff around it. Some PSUs circuit boards even got themselves on fire. Sometimes I wonder how did they pass FCC or whatever certifications they need to enter EU at all.

As far as 80+ PSUs I never encountered issues with various of your so-so brands like EVGA and Coolmax, but I have to admit that those were used in mid-level builds like the one in the OP, not gaming rigs. Never used PSUs above 450-500W for that.

I am not going to buy a PSU above 500W if I don't see a good reputable review of it, regardless of brand.

Even in mid-level builds, the PSUs that I would never recommend might eventually create problems with either stability or just weird and random problems at the software level due to the hardware being subjected to power that's dirty, noisy, and unstable over the course of a couple of years or so. It's worse when the average power draw on the PSU is extremely low, like so low that the efficiency is always below 80%. Cheaper PSUs like that aren't built well enough to handle that and eventually worse problems can start to surface (not always, but sometimes).

I thin I have reffed this before bt if not it is quite a good guide to manufacturers.
