I recently bought a 1000 P2 Supernova PSU second hand, only later to discover it was missing a lot of it's modular cables.

So inorder to use it I had to then go buy a new cable kit for it so I went with the Cable Mods kit that was built for the P2.

So after getting in the cables I finally got everything hooked up, only to have my worst fears realized, in that upon turning it on, pressing the power button on the computer nothing happened.

The odd part that still has me baffled is that the motherboard standby light does illuminate, and oddly enough so does it's RGB along with the cases RGB that is connected through a USB header. Which really seemed odd.

When I press the PC power switch I can hear the motherboard relay click as though it's turned on, and it takes a long press to then make it click again, again, as though it was actually running. But not a single fan on the entire rig, including the PSU fan spin up.

I did receive with the PSU the 24pin test connector that jumps the power wire, and even then I'm not seeing the PSU fan turn on. But I'm also aware some devices don't necessarily always turn the fan on immediately, but instead wait until some heat builds up and it's actually needed. What I don't know is, is this one of those devices and could this potentially be normal behavior or no?

The fact that it's turning on the low voltage rails tells me that at least part of the power supply is still operational, but I don't know how to check the 12 volt rails without being able to turn it on.

I don't really know that anyone here can help but I figured in the off chance that somebody's seen behavior such as this before where it clearly has some type of power output that maybe there's a chance someone can help so I figured I'd post what's happening here and see where that takes me.

Sure, the rig it's self is comprised of a
Asus Prime Z-390-A motherboard
Intel I7-9700K
Cooler Master AIO on the CPU
Corsair Memory - dual 16gb sticks ( not sure off the top of my head the clock speed)
M.2 1TB Samsung 980 NVME SSD
GPU is a MSI RTX 2080 Ventus 8GB OC
Gigabyte Aorus PCIe 1x Wifi 6 / Bluetooth 5.0 expansion card
EVGA 1000P2 SuperNOVA Platinum 80+ Power Supply.
OS intended is WINDOWS 11 (But hasn't been installed yet)

Every piece of this rig is new to me, but not new. It's all been bought 2nd hand slowly over time, as I could afford it, and once I finally had everything I needed, all assembled and tested. But so far that hasn't paned out to well for me as we already know.

I'm fairly knowledgeable and have a decent amount of experience building computers. Built my first PC for Windows XP if that tells you anything.

So yeah been around a while, seen a few things. But up to now I've never encountered symptoms like what I'm seeing from this computer. But I'm at a disadvantage because I've never seen any of these components working, so to be honest I'm only assuming the PSU is my first point of failure.

Update to answer a question:

No I do not have a large majority of the stock cables. So I'm also at a disadvantage there, as I can't confirm or deny the cables I have are functional

Can't seem to post link to the buy page but the cables are the CableMod E-Series Classic ModFlex Sleeved Cable Kit for EVGA G5 / G3 / G2 / P2 / T2 (White)

Cool GTX
heck this, cover post count till you Can post links & the work around

Ok so it seems I don't have rank to post links, but are you suggesting I can't be helped because of that?

I'm very confused

If I'm using the onboard fan as a reference of knowing if the PSU turned on or not, while only connected to the 24pin cable and the test connector on the end, then no, it does not test good.

I have not tested with meter yet

Sorry just realized what you were referencing to about the ECO switch, and after checking, the PSU fan remains off with the switch in either position

NOT good
 
there is a limited secondhand warranty for PSU - base on when item originally shipped  EVGA Warranty
 
last two digits of the serial number tell you which category of --> Transferable Limited Warranty (Second-Hand Purchasers)
 
Register the PSU to your account & then check warranty status  Product Registration

Your welcome,
 
give an update, when you know more

So I'm now attempting to register this thing but I'm getting hung up, but by what I do not know.

I've checked the information I put in 5 times, and I'm positive I didn't have any typos yet every time it's returning with
"The serial number isn't part of the part number" then something about being outside the US.

I truly have no clue what it's talking about. Do you?

Maybe it is saying that serial number does not "register in the database" as belonging to that part number?
 
That would be odd, first thing you would enter is the serial number of the product.  I remember the next screen should list the part number automatically - based on the serial number you previously entered ?


If your sure you did not make a typo in the serial number please contact customer support

I am also wondering was this a replacement PSU for one that was no longer working and if so, what was the symptoms of the old one going out?
