Frequently crashing Dell Precision T1700

Hi everyone, I'm having a serious problem with my Dell Precision T1700.
It keeps crashing, usually when any USB pen drive is connected to it. After it crashes I need to disconnect and turn off the PSU, do the power reset (sometimes couple of times) and then it usually starts working.
I've tried to disconnect most of the components including all drives and USB front panel ports and it's still happening, definetly most of the time when a USB pen drive is connected (I'm in a process of testing the PC without any USB pen drives connected to it).
Does anyone know what could be the problem or what is the next thing that should be tested? I did some research and after a lot of testing it seems to be down to faulty PSU (or the 24pin to 8pin adapter), the motherboard (which would be the worst case) or the 24pin to 8pin power adapter connector from Amazon that I use with my Antec 550W Plus PSU (original Dell's PSU has only two connectors, one 8pin for power and one 4pin for CPU).
Could it be caused by that generic 24pin to 8pin power adpater?
Is there a decent budget PSU (at least 550W) that would be compatible with Dell's 8 pin mobo power port?

Precisions are in the Workstations forum.

Always include version of Windows in your posts!

Look in Windows Event Viewer for any errors logged around the time of a crash, which might point you in the right direction...

You could open a CMD prompt window, Run as administrator, and at the prompt, type in: sfc /scannow and press Enter. Watch for any error messages in the CMD window when sfc is done, or close the CMD window and go to Start>Run, type in: %windir%\Logs\CBS and press Enter. When the folder opens, look at the latest log file for warnings or errors.

The 550 is too small.

You need 150w combined power for the 3.3V/5V

EVGA 700BR is bare minimum recommended.

moddiy is recommeded

I have the same issue. I uninstalled and reinstalled the driver. Then the problem fixed.

Meanwhile, I suspect the reason your system is not booting with the USB drive connected is that you have the BIOS set to boot from a USB device. So go into the BIOS (F2) and check boot drives. You should normally have the CD drive as a priority and your hard drive second. Be sure to disable any USB options. Then you need to restart the computer.

I hope it will work for you.

Computer is booting from SSD, the problem is that it keeps crashing when there is an USB drive connected to it. Then I need usually need to do like 3-5 power resets to get it working again. It seems to be working fine when no pen drive is connected - then it doesn't crash

I've done the sfc /scannow and it didn't find anything wrong
(Windows Resource Protection did not find any integrity violations)

In the log files I don't thing there were any warnings and only errors where like this:
Not able to resolve capability:Hello.Face.Migration.18331~~~~0.0.1.0 [HRESULT = 0x80070490 - ERROR_NOT_FOUND]
and I don't think it's related to those crashes

Is 550W not enough? I only use 1x SSD, 2x 1TB HDD and GTX760-DC20C-2GD5. Do I really need to get PSU with more Watts?
It actually seems that it doesn't crash when no pen drive is  connected. As soon as I connect any pen drive it crashes within couple of hours and keeps crashing.
I think it maybe caused by the 24pin to 8pin power cable converter, that I use although it supposed to be for that Dell model (Precision T1700) and has good reviews on Amazon, nobody has reported any issues

My current PSU (Antec Basiq Power 550W Plus) has a 8 pin connector that fits inside that connector on Dell's motherboard, but for some reason it doesn't work (nothing happens when I connect it and I try to turn it on) 
If my current PSU is not powerful enough than I will probably get a stronger (like that EVGA - 700W 80 Plus Bronze), but if 550W is enough than maybe I will just get new converter from Moddyi

Just wanted to ask if there are any drawbacks of using this sort of converter (since it has only 8pins instead of 24pins)?
Also if I can't get hold of that EVGA PSU - how can I find a different PSU that will work with that Dell motherboard without the converter? What does it need to have, what do I need to look for?

work with that Dell motherboard without the converter 

There is an optional 365w power supply.

https://www.amazon.com/Dell-Optiplex-Precision-Supply-HU365EM-00/dp/B016PLIUFY

Models that have Dell GTX 1060 use that.  This unit DOES NOT supply enough power however to run a GTX 760.

There is also a guy who made his own adapter from scratch.

I will use original Dell PSU for testing if everything else fails. I'm just finishing installing the latest chipset and BIOS drivers, hopefully that will solve the issue.

So there is no EVGA\Corsair\Anker or any other good brand that have a PSU with that Dell power connector?
