Rated 5 out of 5 by Anonymous from Utterly blown away Wow, what an amazing computer. I previously owned an Alienware R11 with a 3090. I would mine crypto with it and the entire room would heat up. Making it a rather unpleasant experience. Now I have this beautiful computer with a 4090. I mine crypto on it and the the computer stays quiet and cool. I'm utterly blown away, now I can mine crypto without disrupting the temperature in my office. This case is a master piece and I cant wait till they sell the case on its own so I can move my old pc components into it. Great deal, exceptional value. Happy customer. 10/10 Great Job HP

Rated 4 out of 5 by thtmnisamnstr from Not a perfect gaming PC but really good (especially at $3k) I've had this PC for almost a month. It is a beast. Everything feels close to instant, and AAA games look beautiful in 4k at high frame rates. The CPU+GPU combination is very good (at least at this point in time). For playing 4k games and streaming from my PC to a handheld, this computer handles everything I need with ease. The cryo chamber seems to work well (temps stay low even with the crazy hot CPU+GPU and 4k realtime ray/path tracing). It is super easy to get into the tower and work on things. The fans are also very quiet for a PC of this size and composition. Overall, I'm very happy with this computer, especially at $3000, which is what I bought it at. That said, it is not a perfect PC. To begin with, 16GB of RAM is low for this setup. I immediately switched out the 2x8GB DDR5 sticks with 2x32GB DDR5 sticks. That led to me discovering that the bios supports XMP (XMP lets you increase RAM speed), but setting up custom XMP profiles and getting them to work is a roll of the dice. It was difficult enough that I gave up on it and am running at the default RAM speed. My last complaint is that Windows Modern Standby, which is the default in Windows 11, causes strange sleep behavior with this PC. This issue is probably the most common complaint for the Omen 45L (especially the power supply clicking on and off). When the PC is sleeping, the power supply will click on and off every few minutes/hour/every few hours (the period changes and I couldn't find a pattern) and occasionally turn the fans on and off. It also doesn't seem to work well with Wake on LAN. To fix these problems, you need to switch to classic S3 Sleep mode. It's a pain to switch, but it gets rid of the sleep problems the 45L has. Honestly, switching from Modern Standby to S3 Sleep should be recommended by HP for all 45L users and they should make a tutorial on how to do it. It's the most common 45L complaint I've come across by a long shot, and I guarantee some people are sending their 45L back on warranty because of this issue. It's not a PC problem. It's a Windows problem, and it can be addressed w/o the PC needing to go back to the factory.

Rated 1 out of 5 by Giovanni A. from Buyer beware Bought this product new. Had to immediately return the product due to faulty hardware. Electrical buzz in case potentially due to the AIO fans malfunctioning. Seemed like the unit was refurbished. Now I have to wait another 2 weeks before I can even be considered to receive another unit. Very concerned about the exchange unit being similar as I have read other horror stories online around this product and faulty hardware.

Rated 5 out of 5 by AnnaReviews from Great pre-built with peculiar settings I never thought I would go to HP to buy a pre-built, but here I am, and I'm very happy with this computer so far! I wanted to mention a few things because this information really ought to be on the specs but is omitted for some reason. Customer service wasn't privy to this information, either. The ram is Kingston 4800 MHz ddr5 (8 gb sticks x2). For some reason HP has underclocked these to run at 4400 MHz. However, after I updated the omen gaming hub software, it offered me the option to overclock to 5200 MHz. The Q&A section says it comes with 800/850 w psu, but mine came with 1200 w cooler master psu. XMP is offered through the bios, but it gives you a warning about voiding the warranty, so I didn't mess with it. You also get a warranty warning if you try to swap power modes to "extreme" in the omen gaming hub (although after last software update, it simply says go to bios - you can't change in hub anymore as of this review). There is lighting software with a lot of nice options, but it only seems to control the lights for the omen symbol and the fans. The GPU and the ram are rainbow, and I haven't figured out how to change it through the HP software. Besides these quirks, the computer ran perfectly out of the box. The packaging was interesting with the "quick release" tabs. The device arrived very quickly and came with a keyboard and mouse (unexpected!). Overall, I'm happy with this purchase!

Rated 4 out of 5 by Markbct from Beast of a PC Let me start by saying this case is unbelievable the way the 4 sides open is smooth and expected The build quality is clean and very expandable. I added the additional 16mb to make it 32 as this should have been standard, I also added a 4tb WD-B NvMe, and my old 6 TB standard drive with my game files from an old Pc , all my upgrades were easily done without any proprietary roadblocks. The couple of things I’m not a fan of is the OMEN interface while I understand some might really like but I’ve stopped launching it. All though this is a beast I9 and RTX 4090 I feel HP isn’t allowing its full potential, after the year is up I will try to investigate it further. Hp is always my first choice and this system was from my last Omen I7 and a 1070 graphics card that ran flawless for gam

Rated 4 out of 5 by Wormycat from Specs wrong Really good design and low noise gamming. Runs games very smooth and looks great. Took a star away due to: specs say it had 4 memory slots but only had 2!
