This review is from: Func surface 1030 Revision 2 XL Mouse Pad
Pros: Great Construction
Cons: The pad wears out quite fast. I owned the original 1030, the orange and blue one from turn of the 00s. I didn't buy this one off Newegg, but I do own this. I am quite dissapointed with this pad. Using this pad regularly for about a year and a half the smoother side has worn down noticeably where the teflon feet of my mouse came in contact with the pad.
Unfortunately this causes inconsistency in using the mouse and moving it around the pad. When it hits the worn out areas, it sticks. It's very distracting. I'll probably just be flipping it over and using the rough side since this isn't a square and you can't rotate it.
Other Thoughts: It's a great pad, the surfaces are awesome, just the durability sucks. It's built amazing, it just doesn't lastREAD FULL REVIEW
This review is from: P3 Kill A Watt Electricity Load Meter and Monitor
Pros: Does what it says it does.
Has nice read outs and display
Cons: I had this thing plugged into a few different computers and simply left them plugged into it. The first one broke after about a week of use. It simply fried. I received a second replacement unit, it lasted a month and a week, after which it also broke.
Other Thoughts: I'm not sure what's going wrong with these units, but it seems like they can't handle the power going through them or something. I was using them on mining systems that drew around ~1500w. They were definitely under the rated wattage on the back of the device which is 1875w.READ FULL REVIEW
Pros: -DC-to-DC conversion, huge fan of this... Love the idea and how Seasonic executed this.
-Quality - Seasonic seems to deliver high quality components even if their website and customer service are shotty
Alright, so I had this in my computer for all of 15 minutes before finding out what a couple of other reviewers were talking about, I'm surprised this isn't widespread. The computer was silent upon booting, so much so that I was impressed. I right away tried stressing it with Prime95 and furmark. I don't have an extreme system, a AMD 8350 and a AMD 7870 for a graphics card. I understand this powersupply ramps up when it goes under load... that is a bit of a understatement.
Within about a minute of starting those tests it went from near silent to jet engine loud. The rest of the components in my system were running cool as always... and quiet as I have custom fan speeds setup and this just blew everything away. It was pushing and sucking more air then I think all the other fans in my system combined were doing. It's not just loud, it's unberably loud. Louder then all my other fans when I ramped them up to 100% which they're never at.
Okay I thought, this is a simulated load and wouldn't be representative of normal computer use. So I removed the load (p95 and furmark) and waited for the fan to spin down... and waited... and waited. It took about 10 minutes before the fan returned to a semi-normal level. Waaaay too long as all my other fans spun down after the heat and load level were gone in about 15 seconds.
The funny thing is, it never returned to it's quiet state even after the load was completely gone... I tried power cycling the computer, that did nothing. I tried removing the power and plugging it back in, that also did nothing... It turns out I had to leave the computer off for around 15 minutes before the fan would reset to it's quiet state, regardless of load and heat levels. This was very aggrivating...
But I persisted. I then fired up the computer in it's quiet state and left it like that without touching it. Within about five minutes the fan spun up to the 'normal' level it was after I tried p95 and furmark earlier. Alright I thought... Maybe this is just normal and it is indeed tolerable...
So I fired up Guildwars 2 to simulate a normal load and within another five minutes it was spinning blender fast and with the noise to boot, even though the load wasn't all that intense. My CPU was running at about 40% load and my graphics card at 100%, but not with the same draw.
So, it went back in the box.
Other Thoughts: It's really a shame, I was actually pretty stoked to get this PSU as my OCZ 500w modular has been slowly giving me problems.
It sounds great on paper and I'm sure it performs up to par and I believe it, that's what makes this so hard. After picking through all the PSUs and coming across Seasonic I thought I found the best at everything except customer service which I really don't mind. The noise really is killer.
I'm surprised more of these reviews don't mention it, but all I can imagine is either they never actually put the PSU under load, they wrote them before they played some games, or they don't play games at all.
I'm sure other games would also yield similar results, especially Battlefield 3 which is quite popular. The fan really is terrible.
I would buy a different Seasonic model, but I'm not sure if this persists through all their models or just this particular series. I'm guessing they use the same fan speed control algorithm in all their PSUs, but they don't list which PSUs use what (most manufacturers are vague on this which is a shame).
Other reviews don't seem to mention this so it's quite hard to gauge whether or not other Seasonic PSUs have similar noise issues, which is also a shame. All you need to do to duplicate my results is run prime 95 for five minutes or so. My system isn't even OC'd... yet, which I'm sure would make these noise issues worse.
There really should be a chart on their website that shows fan speed at certain load levels. More so then that, the fan in PSUs should be based off temperature, not load. If it's frigid cold and the PSU is cold, there is no reason to run the fan at ultra high RPMs even if it is under load. I don't understand why PSU manufacturers are using load instead of temperature for their algorithms (Seasonic isn't the only one). It completely ruins a system builders ability to maintain a quiet system by venting heat through other means (like case fans).
If the case is cool, then once again the PSU fan shouldn't spin like the world is on fire.
I guess I'm going to dig through some more reviews and maybe take a look at Seasonics older M12 series. I'm guessing if they don't have a variable control and simply have a quiet fan that it'll be perfect (the 620w may be like this).
Otherwise I'll be going with Corsair. That was the choice I made, it was between Corsiar and Seasonic, and Seasonic won with it's epic build quality and DC-DC conversion. It's too bad they lost to decibels.
