PSU Critique

[MxRider9637]

I had posted a thread awhile back on psus and alot of people recommended the coolermaster v700 80+gold for $125, But im able to get a sweet deal on the corsair ax760i 80+ platinum for $150... Is it worth the extra money??????? Should i go ahead and get the corsair or stick to the coolermaster??? Also im looking for best performance, build quality, efficiency

Go for the Cooler Master, it's cheaper and the difference isn't any good or worth your money unless you're a Corsair fanboy.

[Josh55]

I tried Enermax and Corsair PSU's before and haven't had any issues, I'd personally go for Corsair tho.

[MxRider9637]

Well which ever has a better build quality, efficient, and also performance..

[Imabigmac]

are you going to sli or crossfire? 

[MxRider9637]

right at this moment no but if i can get a great deal on a gtx780 later down the road (2-3 years) then yes i will go sli.

An extra $25 gets a higher efficiency supply with Link software for monitoring. I personally think it's worth the extra $25.

I doubt there is much of a difference between the two in terms of build quality. Although the CM is a seasonic OEM unit. 

 

Also what TheSLSAMG said.

[MxRider9637]

thats why i had originally picked it because of the great build quality..

I doubt there is much of a difference between the two. Although the CM is a seasonic OEM unit. 

[MxRider9637]

Thats why when i saw it was only $25 more for a more efficient psu and also the monitoring i was like wow!!

corsair.

well its only worth the extra $25 if you are actually going to use the monitoring features. As for efficiency the CM is already Gold and you aren't going to be stressing it out much in the first place. 

[dragosudeki]

I would go for the cheaper option. I'm not too sure Platinum would be worth paying quite a bit more. Maybe if they were the same price...

[MxRider9637]

i hear what you guys are saying.. its just the corsair is $210 orig and i can get it for $150

[DavidGordon]

I'd definitely go for the corsair, I have the Ax760 (Non i) and it's superb 

[Valhallatier]

CM V700 got my vote.

[Faa]

Uh no the AX760i is crap because its noisy.

- Fan profile is complety fucked up. The fan doesnt leave the hybrid mode slowly, the fan ramps up to 2000 rpm and kicks off like 10 times in a minute. This happens a lot in hot environments at idle even.
- You have to use the software to make your psu quiet so basically it isn't a semi passive psu >.<
- Clicking noise with every unit not a defect (youtube.com/watch?v=cTMG5VJcKvo#t=4) see this thread http://forum.corsair.com/v3/showthread.php?t=85166
- The fan is extremely loud, easily audible after a meter at its lowest speed 800 rpm, makes use of a sleeve bearing which is shit


The V700 (seasonic) doesnt have any of these issues and uses a dual ball bearing not sleeve. Avoid 760i/860i/1200i's or any other semi passive psu from flextronics.

See above why you shouldn't. I've used the 860i before, nothing besides a noisy thing. I remember a guy posted a video on youtube about the 860i, complety talking bashing them and Corsair forced him to take that video off.

[MxRider9637]

Thanks for your feedback but i already orderd the PSU and anyways corsair backs up the psu with a 7 year warranty.. If i have any problems i can send it back..

Cancel your order or return it. Theyre not worth it.

The V700 does not used a 2BB fan nor does the AXi uses a sleeve bearing. The V700 uses a Fluid Dynamic Bearing fan from Protechnic, while the AXi uses a mid-range 2BB fan from Yateloon (with the exception of the upcoming AX1500i that also uses a FDB fan).

[MxRider9637]

I know the v700 is good that was my original choice but when i saw i could get a psu with more wattage that will allow me to do sli in the future with 80 + platinum for only $25more i couldn't pass it up

also on jonny gurus reviews the v700 scored a 9.1/10 were as the ax870i (same exact thing as ax760i only the wattage is different) scored a 9.7/10...

Yeah, I know it was your original choice. I'm pretty sure I had recommended to you. In fact, I believe I had recommended a 550w unit at first and only suggest the V700 due to the Mail-in-rebate that was offer at the time, that effectively made it to be an $90-ish PSU - making it in the same price range as some of the 550~650w units.

 

Anyways, the review was done by two different people, and you shouldn't used the scoring to judge two unit. What is rated to be 9.7 a few years ago may be only 8.x today (not saying that the AX860i would be rated that low, just making a point). For example, the value of the V700 should go up (was score 7.5 due to it being ~$159.99), considering how the V700 is $124.99, and there are occasional MIR that I had seen a few times already. Functionally, it got deducted because of the lack of a second EPS12v connector and the length of the SATA cable to reach to the top of a full tower case. Your Asus Maximus VI Hero only needs one EPS12v connector, so the first point isn't an issue (you may be able to request for a second one though), while the 760T you are getting is a full tower case when might be an issue if you are have and optical drive or whatever.

 

Since you already bought it, hope you enjoy it. It is a solidly build and well performing unit.

Then he failed to review them properly.

 

 

The Corsair AX1200i is the second 1200W power supply we have seen from Corsair. Today's Corsair AX1200i power supply, like the AX1200 before it, comes equipped with a 140mm fan and very good efficiency as today we see a claimed bump from an 80 Plus Gold to an 80 Plus Platinum rating. However, the previous AX1200 was not exactly a quiet power supply, not obnoxious either but it wasn’t as quiet as we initially saw from Corsair relative to the competition. Today, the AX1200i adds a fanless mode which should help its overall noise profile. It, however, did not. In fact, the fanless operation mode is really kind of wonky at best. When we start the unit at loads that should mean the unit is going to run fanless the fan starts, and it starts fast and loud. Then, after a number of seconds, the fan then shuts down. When it does come back on again, the fan spools up more normally and the noise profile seems to be more tolerable at first. However, like with the AX1200, that was during the first 50% of its DC output capacity the AX1200i. After that level, however, the unit’s fan began to spin up and tests thereafter only increased in the noise it was contributing to the load testing environment. Corsair's provided documentation again claims a peak noise value of 30 dBa at full load. Again, that claim is unlikely at best, which is being generous, in real world use. Add to that the issues with the fanless mode we encountered today and we have to say that this unit is less well suited for quiet cooling environments than the AX1200 that preceded it. Not exactly the direction of progress you like to see with product development.

 

With the Corsair AX1200 being the last 1200W power supply we saw from Corsair, the pedigree for quiet in this output range wasn’t there to begin with. The AX1200i did, however, attempt to change our minds with the promise of fanless operation and the return of the promise of only a 30dBa noise profile. However, neither of those things really came true. First, the fanless operation mode included an initial ramp of the fan before it shut off that was plain LOUD. This was followed by the unit following in the footsteps of the AX1200 and being loud at load levels above 50% in our testing environment which is more than 30dBa. It could just be that our testing environment is too demanding for this Corsair unit to operate the way Corsair would like it too, but other units have done much better under the same circumstances and as such this does represent another serious misstep for this unit.

 

Like the AX1200 before it, the AX1200i is supposed to represent the pinnacle of Corsair’s product lines. With that being the case, there were serious errors with the AX1200i execution today. The fact that the unit missed the 80 Plus Platinum numbers on the bottom end, the kludges in the build, the worsening Transient Load Tests results, and the fan/noise problems all make it seem like that Corsair spent more time playing around with the Corsair Link software (if you can find it) rather than the product it was supposed to be controlling. Sure the software is supposed to let you tweak things like the output voltages and the fan settings, but let’s be honest here; if you have to tweak these things to get these "right," these were "wrong" when you bought the product and that is unacceptable on a product of this price point. Like NVIDIA’s ESA before it, the Corsair Link software control idea is a solution looking for a problem. Companies are always looking for ways to distinguish its products in what has become a very difficult commodity electronics market, but when the fundamentals have issues it would behoove people to get all of those perfect first before going with questionable utility "options.

If you can, cancel your order or return it and get a better psu instead that's atleast a real semi passive psu there are plenty of quieter psu's xfx, seasonic and so on..

And? Theyre still noisy and they wear easily out. Most AX1200's ive seen the bearing went out..

Then he failed to review them properly.

 

They had reviewed them properly in accordance to their testing methodology and criteria for their PSU reviews. Considering how you are looking for a more in-depth review regarding noise, Jonnyguru.com isn't exactly the best site for you, as they don't put much emphasis on it. Site like HardwareSecrets don't either, and it was just recently that TPU had stated to do dBA readings on their reviews.

And...you'd provided inaccurate information regarding the fan type, and I'd merely corrected it. I never disagree with the CM V series having a better fan, and I don't agree with the usage of the Yateloon D14BH-12 in a premium unit such as the AXi, while the non-I AX offer a better Sanyo Denki 2BB fan. You would have thought the AXi would used the same fan or a FDB fan upon announcement. The YL is something I had expected to see in mid-range unit such as their TX line.

 

I don't have the data for the numbers of units in which had failed due the fan, nor do I have one for the numbers of sales. So whether or not the failures you have seen is relevant to the mass of units sold, I'm not going to argue about. It is a loud fan though that is used in their AX1200/AXi, HX, and TX line. It is a 2800 RPM fan (2300RPM with the D12H-12 on lower wattage units), as well as it susceptible to low-RPM noises that many 2BB fan has.

According to their testing yeah and the opinion if they done it properly is on our side not on their side. TPU's testing method doesnt say anything about the hybrid mode so they failed giving criticial information about it in their conclusion page. All the psu's we see from corsair, be quiet etc are all within the atx spec, so voltage regulation/ripple etc is just irrelevant all that's left is noise what we care about.

I'm having it about the bearing wearing in a year or two out, that will make the fan even more noisy.
