XPS 8950, powers on, then off
As the title states, I have a XPS 8950 that is not powering on. I press the power button, hear a click, fans start spinning then hear another click and everything powers down. It tries about 3 times on it's own then nothing happens after. If I remove the power cable and plug it back in, it does the same thing, see a green light turn on in the back with the click, then another click and the green light turns off.
I went over this with tech support, unplugging components, removing RAM, GPU, ethernet card, and nothing changes.
Tech said it's the motherboard and thankfully i'm still under warranty, just curious if this is normal behavior? Never had a motherboard fail on me but many times a power supply.
I was sure it was the power supply after reading that these systems are way under powered with the 460w PSU. I also have the i9 and 3060Ti, not sure why they ship these computers with such small PSUs and when I built the system earlier this year I don't even recall there being an option for a larger supply.

1. No
2. You will find out which part (Motherboard, Power-Supply, etc.) after they repair it and it is working again.
3. Yeah, me either. I prefer an "over-sized" PS so it runs cooler and amps/voltages are more-stable.
I say it should throw a "config error" on the Sales Configurator page. The higher amp Power-Supply was likely optionally selectable down towards the bottom of the page (unless it was a Pre-Config/Ready-to-Ship unit).

Good analogy actually.
Like buying a nice Lexus (so already expensive) but getting the smallest engine, no AWD, and lowest trim package.
It will be slow, not sure-footed in the rain, and lots of "creature comfort" features are missing. However, your payments will still be very high.

When the service tech comes to replace your motherboard, have them bring a 1000 watt PSU as well.

Update on this.
The tech came with a new motherboard, changed it and the same thing was happening.
They ordered a new PSU and another motherboard, came a second time and the exact same thing keeps happening.
They tried everything, removing the GPU, RAM, basically everything except the CPU and the same issue, powers on, fans spin for a second or two, and then turns off. Tried removing battery to clear CMOS and it didn't change anything.
I've personally built quite a few rigs and never had an issue like this. I think it MAY be the CPU, but the motherboard doesn't even give any beeps to tell me what the issue may be.
It's being shipped back to Dell for diagnostics because they're out of ideas.

I ran into this today with my new (about 4 months old) 8950. Front power button does not work any more however the LED blinks twice (with several seconds pause in between) when I unplug the power cable and plug back in. Basically, the system turns on & off twice. And that's it. It stays off after that. Any further troubleshooting tips? I tried hard reset etc. No luck

Do you need to rebuild and/or increase the size of the icon cache? CAVEAT: You edit the registry at your own risk, so always safest to export a copy of the registry before making any changes.

How did this turn out?
This happened to mine yesterday. what I have noticed is when I unplug power from the ATX CPU1 and ATX CPU2 the fans will stay running and I can hear the hard drive starting.
I ordered a new power supply before I found the above so it probably isn't the PSU and looks more like a CPU issue
my warranty ended last month.........JOY

It is not normal, but 460w psu is not the cause. Dell offered 750 w then later 1000w psu but if you do not specifically look for the high power psu option 460w becomes entry level default.
Dell sales page is not up front transparent of all the configuration options. Whether that is sales intentional or not, it is debatable. A common buyer not reading the spec details carefully can easily pay big bucks for the lowest end spec. Almost like buying new cars but hope they are not as bad or shady.
