Thank you for posting on HP Forums,
The Riddle_Decipher is at your service.
I understand you need information on connecting PSU and CPU cooler to your Omen X desktop,
I'll be glad to help you out, however, for an accurate solution I will need more details:
What is the product number of your device? Use this link to find it: http://support.hp.com/us-en/document/c03754824
(Ensure you do not share any of your personal information such as serial, phone number, email ID, etc...).
Is it Omen X by HP 900-099nn or the 900-100?
While you respond to that, did you check the hardware reference guide?
(If you haven't, Click here to view the guide for HP Omen x 900-099nn)
That said, The computer supports power supplies that follow the ATX standard with a maximum of 1450 W.
The radiator bracket can accommodate only 240 mm radiators.
