This review is from: Corsair Gaming M65 RGB Laser Gaming Mouse - White
Pros: Construction quality is superb, with an all aluminum body, and removable weights.
Dedicated sniper button is large and well-placed - with a modified claw grip I place my thumb tip just above it and can actuate the button by straightening my thumb slightly. When not using the mouse in FPS games, the Corsair Utility Engine (CUE) software can be used to reprogram the button to another function, or deactivate it if desired.
CUE software is highly configurable and pretty easy to use to reassign any or all of the buttons, and also control the lighting and DPI settings.
Tracking is very consistent, even on rough surfaces like the arm of my (leather) couch.
Although it has the same Omron switches as other gaming mice (I have the Roccat Kone XTD, Corsair Sabre, and Tek Syndicate Gaming mouse) they seem crisper in operation, even though the other mice are by no means mushy.
The scroll wheel is light to rotate, yet the steps are positive. Middle click is easy to use without mistakenly scrolling.
Elegant design and a good fit for my medium sized hands.
Cons: If not being used for FPS gaming, there are better choices available with more buttons. Some may find the sniper button too easy to click accidentally (even though it can be disabled or reassigned), and a palm grip can accentuate this issue. Claw grip users may find the palm swell excessive, though I got used to it.
The top surface of the white version can get sweaty and a bit slippery.
The above points are minor, but the price is more than I would be willing to pay for any mouse (Note: I was sent the M65 to review).
Other Thoughts: This is absolutely the best constructed, most solidly built mouse I have used, with no rattling or loose parts even after several accidental drops to a hardwood floor (my other mice have had parts come loose after such mistreatment). Every button has a crisp, positive actuation, and the tracking is excellent.
The mouse is heavy even after removing all the weights. I am used to it now, although I prefer a lighter mouse - one of the features/benefits/drawbacks (depending on your viewpoint) of an all metal body.
I've been using this mouse for two weeks now. I was not in the habit of using a sniper button before and it took some getting used to as I kept accidentally pressing it before I changed my grip (from palm to modified claw).
For build quality, performance, ease of use and appearance, I would award five eggs without hesitation, but I must deduct an egg when considering value for money, since the price is so high ($119.95 at time of writing).
This review is from: CyberPower GX1325U 1325 VA 810 Watts 10 Outlets UPS
Pros: Simple to use - just charge to full capacity and plug in your computer and monitor (ensuring they and other accessories do not exceed the 810W power limit). It works even without the software, though this adds useful functionality via the supplied USB cable.
Operates in "Bypass Mode" (bypassing the transformer) when power is normal, for greater efficiency.
The software allows monitoring of battery status, keeps track of over and under-voltages the unit encounters (limits can be user-specified), and importantly, lets you specify how long you would like to run on battery power before gracefully shutting down your PC.
Since I acquired the unit, it has kicked in twice due to temporary brownouts. I also own its older, more powerful sibling, the 900W CyberPower CP1500PFCLCD, and it kicked in at exactly the same time on both occasions.
A "Test" button in the software allows you to try out its functionality by switching to battery power for several seconds. I tried this with my PC plugged in (I was a little nervous) but it worked without problems. The alarm sounded as it switched over, then turned off when regular power was restored. Note: the alarm can also be silenced if desired.
The front LCD gives readouts of things like input voltage, battery life, load capacity of the battery outlets, battery charge level percentage, etc., though if the unit is hidden away under a desk, it is not that useful, and the software GUI is easier to use.
Cons: Bulky and obviously heavy due to the lead acid battery - but that is true of all UPS products in this range.
I am wary of the purported runtime due to previous experience with other UPS units (I have owned four by CyberPower), as they seem to give only a fraction of the advertised usage while your PC is actually running. It's best to save your work and then shut down as soon as possible, in my opinion.
The "Sine Wave" output adds significantly to the cost, but a former model I owned, the non-sine wave CP1500AVRLCD never caused a problem with the Active PFC power supply connected to it. OTOH that unit finally died after a power outage when I switched on the mains breaker (following power recovery) while it was still plugged in. On disassembly I found four transistors on one of the internal PCBs completely fried.
Other Thoughts: I have never had a PC break down or had its OS corrupted while not using a UPS when a blackout happened, but then I was not in the middle of working on a project, and my PC was evidently not writing critical data to the file system when they occurred. At least a UPS gives peace of mind in that regard.
I am not using the unit's coax or network protection (I already have enough wiring to contend with), just the mains battery backup and surge protection.
Make sure you don't plug too many accessories into the outlets, even if they are only using the surge protection. It's only common sense not to plus a vacuum cleaner or microwave into them of course, even if your computer is using half the rated output, but the power cord can only safely handle so much.
I was tempted to drop an Egg due to the somewhat misleading runtime estimate, but I expected this from prior experience. In two weeks of use this UPS has functioned as it should. It has switched to battery power twice due to outside circumstances, and twice when I used the self-test function, so I am awarding it five Eggs. I would recommend this product to others, based on my experience with this and other CyberPower UPS units.
Note: This product was provided to me by Newegg for review purposes. I only award five Eggs when I feel a product is worthy and will reduce my rating for anything more than minor Cons, or more than a couple of minor issues.
This review is from: Corsair Hydro Series™ H80i V2 Water / Liquid CPU Cooler. 120mm CW-9060024-WW
Pros: Keeps my i7-4790K adequately cool at stock clock speeds.
Looks great with the new braided cloth covered hoses.
Corsair Link is much improved over earlier versions and can also set alerts eg. turn the waterblock LED color red (or color of choice) if your CPU goes above a defined temperature or perform an action eg. set fans to 100%, shut down your PC, run a program, etc..
Reasonably easy to install, especially the waterblock.
Cons: The stock fans are too loud, in my opinion. On Quiet mode, there is a slight, but annoying whine, and Performance mode has this plus wind noise. Balanced mode is best in my setup as the whine disappears at the cost of an increase in wind noise. Between each mode there is only about 2 degrees difference in temperature at full load.
Overclocking my 4790K to 4.5GHz or even 4.6GHz, using the "Easy overclock" function on my Gigabyte Z97 Gaming G1 mobo, and using Cinebench (rather than the more stressful Prime95) to run the cores at 100%, CPU temperature went up to 90C even with Performance mode set in Corsair Link. This is probably because the vCore is set a little high with the Gigabyte utility at around 1.35V, but I prefer my CPU remain under 80 degrees, which the H80i can handle easily at stock speeds (4.0GHz with 4.4GHz Turbo).
The hoses look great, but are too long to install the radiator easily in the recommended position at the rear, and are quite stiff. In my Fractal Define R4 case, and with my Gigabyte Z97 Gaming G1 motherboard, one hose pushes on my top video card since the top video card slot is the first PCI-e slot (as it supports 4-way SLI). Most boards have a PCI-e x1 slot in this position, so this may be less of a problem for others.
The backplate is made of plastic, and despite careful installation using only finger tightening, I think one of the threads may have been stripped when I installed (I was trying to say "scr*wed", but that is censored) the retaining bolts.
Once the "Alert" level is reached in Corsair Link, if you have set fans to 100% and/or LED color to red etc., they remain at that setting even if the temperature drops below that level. Or at least, I have not found a way to reset them without a reboot.
Other Thoughts: I have mixed feelings about this cooler and Corsair's recommendations regarding installation. They suggest orienting the fans as intake fans, which would pull cooler air from outside and help lower CPU temperature. This would raise temperatures inside the case and not help my aircooled ASUS DirectCu II SLI GTX 670s at all. A single GPU may fare better.
The hoses are of a length which would make mounting at the case front easier, but Corsair suggests to mount at the rear, which would also reverse typical airflow direction if you mount the fans as intake fans, plus you would need to add a dust filter.
On the other hand, this could be a great cooler for a mini-itx build in a case where you don't have room for a 240mm radiator. I am using a Corsair H100i in my primary rig (with an i7-6700K), and replaced its stock fans with Corsair SP120 (Quiet Edition), which greatly improved the noise level and still outperforms the H80i despite much lower fan speeds. A similar substitution could help with the H80i V2, at some cost of course, plus higher temperatures.
Final thoughts: If you have room for a 240mm AIO cooler I would go for that option.
Otherwise, if you can mount this cooler where noise will be minimized (i.e. not at the rear) and the hose length is not a problem, then this performs adequately with a rather hot running CPU such as my i7-4790K and likely a lot better with an i5 or lower clocked CPU. It could also be a hot contender (poor phrasing, sorry) for an aftermarket GPU watercooling solution for reference video cards.
Note: The Corsair H80i V2 was provided to me by Newegg for the purposes of this review. I like Corsair products in general, with Corsair Dominator RAM in the rig I used for testing, and Corsair Quiet Edition fans in my main rig and their original H100i AIO cooler. My fair opinion is that I would give it 3.5 Eggs if possible, but with the noise level of the stock fans and my personal issues with the hose length and stiffness, I am rounding it down to three rather than up to four Eggs.
