SOLVED Unable to boot with any hard drives receiving power

[DGenerateKane]

I've read several threads with people recommending the Seasonic G series, so of course I got one. And it wouldn't power on. Got a replacement. Won't power on. Further testing found that it can power on, so long as no hard drives are plugged in at all. None. It's 550w, so power should not be a problem. While waiting for a replacement, I plugged in a Thermaltake SMART Series SP-750M 750W ATX 12V V2.3 & EPS 12V SLI CrossFire 80 PLUS BRONZE Certified Modular Active PFC Power Supply and it booted just fine with all four drives. Now, I admit I have no knowledge of wattage requirements, but I at one point had a computer with a 10 year old 550w PSU running twelve hard drives, two optical drives and a low profile video card. So I don't understand why this one can't power on with even one hard drive.


Here is my setup for reference:

Edit: Of course I solved it after posting, the sata power cables I tried were bad. Finally found one that worked. :/

Yeah, I'd have a hard time believing that a Seasonic and its replacement would both be bad. Can you explain what cables you were using and why?

 

[DGenerateKane]

I was using cables from the 750w power supply, which worked just fine with it. Just wouldn't work with the Seasonic. I assumed modular cables were universal. Are they not?

No, never assume that. Within the same family, they may be (G-450 and G-550, for instance). Between completely different PSUs, don't even think about it.

OMFG. There's a good chance you've ruined one or more pieces of hardware by mixing cables. They are not universal, even across the same brand and product line.

 

[DGenerateKane]

Sure wish they didn't have identical connectors. Or were labeled, considering they are all identical. Now I'm going to have to get more as the cables provided are woefully inadequate for my build once I get all the drives I want. And make sure not to mix up any as I have 3 modular PSU's in the house with more expected.

With a little digging you might discover that seasonic is actually the oem supplier for thermaltake. They build for many. Also remember that while there are no set standards and you can blow stuff up, the factory is going to reuse sku's and parts everywhere they can. They likely source cables from the same catalog and supplier. It is a big incestuous game. ;)

It should be a pretty simple matter to validate a cable and pinout if you are reasonably competent with a meter, or just a cheap psu tester from the local computer shop. Swapping random cables is lunacy, but you are allowed to be smart. It's just WIRE.
