Hey there, thank you for taking some time to read through my question, I appreciate it.

I just purchased a brand new Seasonic X 850W Gold PSU and now when I Shut Down my computer it automatically turns itself back on. Sometimes after it turns itself on it turns itself off 5-6 seconds later, while sometimes it manages to turn itself on entirely. I'm also experiencing a slow boot, the first loading screen appears 5 seconds while it usually took less than 1 second with my SSD.

I double checked all cables, turned off all sleep/battery saving modes. Replaced it with my old PSU and it worked perfectly, no slow boot times nor nothing.

Perhaps I've already laid down the answer here for myself, but I'm wondering if there could be anything else, aside from the PSU that's causing it. (I assume I'll return it tomorrow)

Thank you for your time, best regards, Fred

It seems like the psu is faulty. You shoud return it as soon as possible.

All suggestions are welcome, don't hesitate to comment. I'm just curious if this could be anything but my PSU. Or if anyone has heard of some similar issues with a faulty PSU.

Regards, Fred

I returned it and it was a faulty PSU. When they tested it, it didn't quite turn on automatically, but it did have a slow start up. Reason for that slow start up was, that the computer did a bios reset every time the computer was turned on. We don't know why or what caused this problem, but it happened to my computer and two others at the store, thus the PSU was declared faulty.

Got refunded and went to another store and put down a order for Seasonic X 1250w Gold PSU. I wasn't going to buy this bad boy, but when you only need to add like 70$ for that jump, I just had to do it. (It's also easier when you feel like you're only paying that 70$ since the rest was invented on the 850w PSU)

Wow! That PSU is way overkill! Why do you need so much, do you run more than 2 GPUs?

Be mindful that the PSU is rated gold at loads above 20% (250W in your case) so if you use to little power then the efficiency is going to be horrible.

This is my current rig

-ASRock Z87 Extreme6 ATX Intel LGA1150
-Core i7-4770K Haswell OC-ED to 4.0 Ghz
- 2x AMD Radeon R9-280x Gigabyte OC.V
-G.Skill 16GB (2x8GB) Ares 2133MHz DDR3
-250GB Samsung 840 EVO SATA3 SSD
-3TB Toshiba DT01ACA300 SATA3
-2TB WD Black
-1TB WD Black
-Asus 27" LED WideScreen, VE278Q
-Aerocool Strike-X ST Devil Red XL-ATX

The PSU will definitely be an overkill. But I'll be ocing the CPU later, most likely with water cooling. There's basically no limit for what I can do at this point, PSU wise. Appreciate the replies G3ox! :-)
