Rated 1 out of 5 by RMKL from Disappointing Product I had a very disappointing experience with this product and the exchange experience. Right after receiving the PC, the first BIOS update caused the computer to completely stop working. Also there were some other unidentifiable issues making the pc not working properly. I spent hours trying to resolve the issue, but nothing worked. For such an expensive PC, this was a huge letdown. Overall, this has been a horrible experience, and I expected much better from HP.

Rated 1 out of 5 by Bids1989 from Screens go black and Fans blow full throttle When playing games my monitors will go black and the GPU fans will blow full speed. HP deemed it a graphics card error. They replaced and it just last month it started happening again, with a different GPU. I owned this PC for 12 months now and 6 of them this issue has been happening. Hands down the biggest regret purchase of my life.

Rated 2 out of 5 by Matt419 from PC shuts down randomly. My PC randomly shuts down while playing games with the fan blowing very loud for a minute or two. I submitted my problem to the Microsoft page and provided a minidump file. They said there's something wrong with the graphics card. This is not something that you want when you're spending over $5000 for a PC.

Can you confirm which power supply unit the gt22-1455xt. In one question answered someone says the omen has 800W but in another question someone says it will be 1200W.

Asked by: Michael8831
This OMEN 45L Gaming Desktop GT22-1455xt is a customizable PC. The PSU for this PC depends on which configuration is chosen. Both answers are correct. The answer in question was asked about a specific configuration. That configuration required a 1200W PSU due to the power requirements of the GPU. The base version of this OMEN 45L Gaming Desktop GT22-1455xt comes with the 800W PSU due to the power requirements of the GPU on the base version. Hope this clears it up!
