Pros: 3 PCI-3 slots at 16x in a board under 250 bucks I shouldn't have to say more. Great lay out you PCI slots are spaced so your graphics cards are not jammed together, and they don't cover your other slots when using double width cards. good bios easy to use even if your not a super tech person. only had it for two weeks it is running stable with out any hitches so far.

Cons: Could use more on board fan connections. and only one onboard USB 3 plug in.

Pros: see first review

Cons: Since my first review I got the power switch working. the switch was not bad the outside button did not have enough play to depress the switch I backed the screws out half a turn and now it works. I discover this when I had a noise in the front fan and took the cover off to investigate. The fan was hitting the case put a piece of cardboard in as a spacer. I pushed the power button not expecting it to work but it did. Hope this helps others with the issue. The head phone jack still does not work. In my first review I said the power supply screws where striped. That was not the correct term the where cross threaded so the screws could not be easily turned by hand they you need a screw driver to take them in and out.

Overall Review: Note to Cooler Master and Newegg. I am leaving this review at 3 eggs I would have raised it to 4 over getting the power switch to work. Because you sent a reply with a phone number saying you wanted to make this right I have tried that number at least 20 time no one ever answers it just rings. If you want to make me happy send me 6 replacement thumb screws that is all it will take. I do not care about the head phone jack it is something I normally do not use. I only used it because I did not have speaker at the time.

Pros: Pro I do know yet can not get them running see cons

Cons: This requires a PCIe cable and open slot in your power supply. Unfortunately my 1000w power supply only has 6, 4 for my 4090, 2 for my cpu oops. Corsair you created cable management nightmare trying to fix one. Having to use a long PCIe cable to power it will make it tuff in small cases. A longer power cable that would plug in directly much better idea. even better if it was STA slot instead. with M.2 drives I have plenty of those open

Overall Review: Do your research before you buy. I have to order a new power supply now really sucks

Pros: Very easy to install ( Kinda if you have spare PCIe cable and open PCIe open on your power supply on your )

Cons: it requires a separate PCIe cable and open plug on your power supply. I have the long cable but not and open PCIR plug in. my 1000w corsair power supply only has six I need 4 for my GTX 4090 2 for my CPU. Now I have t5o order a 1200w power supply. Really sucks. Corsair this is a great idea and product making us use a PCIe cable and slot to power is id not a good idea. A little longer cable that would directly plug in directly would help, having it powered from an sta slot even better. With M.2 drives most everyone has an extra one open

Overall Review: Do your research before you buy

Pros: Great closed loop system. Easy to install brackets are well marked. so no guess work. Does its job have not over clocked yet at idle I am 25C and 32C maxed out running Haswell I5K

Cons: Tube are a little stiff. but you can turn them at the pump which makes up for it.

Overall Review: I mounted this in the cooler master HAF XB EVO

Pros: this is a great card I have two in sly they never hiccup on anything I though at them Stay cool even under load.

Cons: none
