De1taE1even Posted November 2, 2016 Share Posted November 2, 2016 I consider myself to be a generally smart person, but after this mistake, a re-evaluation might be necessary. I decided to upgrade the power supply in my machine, since I've added lots of hardware since I first built it. I was upgrading from a Corsair CX500M to an EVGA 650P2. Simple enough, right? For most people, it probably is, but I'm an idiot. In my infinite laziness, I decided, since both power supplies are modular, I'd just use the corsair cables and plug them into the new power supply, where applicable. The SATA power connectors on both power supplies look identical, a common 6-pin molex connector. Should be universal, right? WRONG. Looking back now, I can't believe how stupid I was to just assume this would work, without at least performing a quick Google search. 30 seconds of research would have saved me a lot of money. So, I got everything wired up, plugged it in, powered it on, and heard two pops. The first was every single hard drive's pcb saying goodbye to the known world simultaneously, and the second was my heart breaking. So, very expensive lesson learned, modular power supply cables are NOT universal. Quote Link to comment

tdallen Posted November 2, 2016 Share Posted November 2, 2016 Wow . If it makes you feel even slightly better, I think this post will make a real difference for someone's upgrade plans. Unfortunately it will be someone else . Quote Link to comment
CHBMB Posted November 2, 2016 Share Posted November 2, 2016 Ouch.... Mate, so sorry to hear that. I've replaced a PSU like you and fortunately I replaced the cables as I preferred the newer cables that were supplied, mine were both from the same manufacturer though, such an easy pitfall to get caught in and it's very logical to assume they would be universal... Thanks for posting, I'm sure you're not the first this has happened to and I bet you won't be the last either unfortunately.... Insured? Quote Link to comment
De1taE1even Posted November 3, 2016 Author Share Posted November 3, 2016 Thanks everyone, hopefully this will keep others from making the same mistake. Insured? Hmm... I never thought about that. You talking about home owners insurance? I wouldn't think something like this would be covered, but then again I've never looked into it. I'll Google a bit to see. EDIT: Actually now that I think about it, I'm pretty sure my deductible is $1000 so I don't think it'd be worth the claim. I'll talk to my agent though just to be sure. Quote Link to comment
CHBMB Posted November 3, 2016 Share Posted November 3, 2016 You 100% sure it wasn't a power surge? Rather than the replacement PSU.... Just saying.. Quote Link to comment
John_M Posted November 3, 2016 Share Posted November 3, 2016 This sad tale has got me wondering if it's even safe to assume that the cables a given manufacturer uses are compatible across its own product line. Over the years I've used several modular power supplies by Corsair (AX, TX HX and RM series) and I've simply put the spare cables together in a box. I've only ever added to that collection, never having the need to take any out. Perhaps I ought to go through them all with a meter. EDIT: Hmmm. It seems as though there are indeed some compatibility issues even within that one manufacturer's range: https://www.reddit.com/r/hardware/comments/2v42b1/psa_modular_power_supply_cables_are_not_swappable EDIT: Actually HX, not TX.

JonathanM Posted November 3, 2016 Share Posted November 3, 2016 Perhaps I ought to go through them all with a meter. This, exactly. I strongly recommend checking the pinout with a meter and group like with like, preferably with a label enumerating the pinout. That way if you get the urge to use them, you know for sure before you take a risk. Quote Link to comment

After my blunder, I looked at the molex side of the connector and the used pins are physically different. Quote Link to comment

John_M Posted November 3, 2016 Share Posted November 3, 2016 Well, I tested them all with a multimeter and there are indeed differences. Thanks for raising this issue. It seems very strange to me that Corsair would do things that way. Surely it would be cheaper for them to produce one standard set of cables that are compatible with all their power supplies. The only explanation I can think of is that some product lines were acquired from other manufacturers. Quote Link to comment

Seriously ... How could ANYONE be so STUPID !! :) . . . ... Trust me, that's nothing compared to some FAR more obvious screw-ups I've seen (and done myself) over the years. I could tell a lot of stories -- but one that's at least a bit similar was when I worked at NATO in Brussels, and had a contract with a small company from California to deliver a micro-computer based system (the bulk of the cost was software). The President of the company flew to Brussels to make the actual delivery. He had the computer, a NEC Multisync monitor, etc. to install. The power supply for the computer had a 120/240 switch, which he dutifully set to 240 (as required). The supply also had a convenience outlet on it (fairly common in those days -- late 80's) -- and he plugged the 120v monitor into that outlet. I TOLD him that wasn't right ... that he needed to pick up a transformer for the monitor. But he assured me he "knew what he was doing" and that I just didn't understand the technology. He then proceeded to plug in the computer; and when he pushed the power button on the monitor there was a loud POP as the 240v input fried it ... He then headed to a computer store in Brussels to buy a 240v monitor -- which, of course, his company had to pay for. (and in those days that was ~ a $1000 display) Now THAT was truly stupid -- HE clearly didn't understand how a power supply worked. Quote Link to comment

The more I thought about what I did, the more I realized how easy it would be to screw it up. Immediately after it happened though, my anger overrode my reasoning, as I paced around the house proclaiming to the world how stupid I was. I am the absolute representation of why parity and backup are 2 VERY different things, both of which are required if you care about your data. It may have cost a fair bit of money, but it was my backup server, so no data lost. Quote Link to comment

The only explanation I can think of is that some product lines were acquired from other manufacturers. Most of the name brand power supplier "manufacturers" just rebrand other manufacturer's products. Not too many actually design and make their own supplies. Most supplies are usually SuperFlower or Seasonic rebranded, with minor changes in pcb population. It would cost them a penny or two more to have them redo the output configuration to match their other supplies. Quote Link to comment

I had a simple melt-down of a Molex-SATA power adapter. Gary chimed in to answer some questions I had and informed me that some people manage to force Molex connectors on backwards. So... you're not THAT stupid! (Happy to report that I passed his intelligence test by pointing out that Molex connectors are keyed! ) Quote Link to comment

Bought a workbench about two hours later. Quote Link to comment
