Which is the best power supply?

 

EVGA 500 Watts 80 plus white

EVGA 600B 80 plus Bronze

XFX XT 500/600 series

Corsair CX550M/CX650M

 

CXMs, then 600B. Behind, then XT, then last place is the EVGA 500 W1

My gtx 960 strix asus has coil whine during heavy load on videogames, it is normal? Is Coil Whine dangerous for my graphics card?

The GTX 960 is installed with Seasonic s12II 80 plus bronze 520 watts 5 years warranty

You shouldn't post this question on the PSU TIer List thread. Make a thread, or check out the TechQuickie

Coil whine is fine and has nothing to do with the PSU, unless the PSU is making the sound.

Eh, sometimes the PSU can contribute to GPU coil whine. IDK why, perhaps an electrical engineer can comment on it, but my friend's 270X lost its coil whine issues when we replaced his craptastic PSU with a CX450M. I've read other anecdotal examples of this.

There is no 2015 CX550M

Huh? http://www.corsair.com/en-us/cx-series-cx550m-550-watt-80-plus-bronze-certified-modular-atx-psu-na

 

Besides existing, it's also group regulated, far as I could find, which would put it no higher than the same T4 here and in some places costs more than the non-modular 2017 CX550.

Probably mixed the 2015 CXM with the 2017 CX? 

The CX550M is DC-DC

CXM Green (T4) ends in x30 or x00. CXM Grey (T3/T2) ends in x50. That's DC-DC.

Show us a review and we'll figure that out, right now there are none. Play it safe and don't buy one until it's been reviewed, no matter who the manufacturer is.

That's not a review. Just internal pics.

 

I believe someone saying it's custom.

I was a little off, this series came out late 2016. But not in 2015.

Looks like the same platform as the GQ. Other than the choice in capacitors / protection circuits being bad, It's probably alright. Still, no review no buy.

 

Also @jonnyGURU is that an in-cable cap I spy?

Yes, no review pics, nothing known about it.

Its just a crappy copy of be quiets Pure Power 10.

Why are you so obsessed with unknown EVGA units?!
Why not get a decent PSU from a manufacturer that doesn't sleep with everybody??

No, just regular zip tie.
Doesn't look that great but is better than the stiff glued heatshrink because its not as stiff in that part.

Nono, keep making PSUs, just don't make so many different ones. Stick with the B2, G3, P2 and T2. Everything else is redundant ffs

Extend the B2 line with some sort of custom Super Flower, but make it right, call it the B4, make a Leadex II Gold G4, and do something with P2/T2 to make it better and skip 3

You'd think they'd mention it somewhere on the page in that case. In fact, all grey CXMs omitting that feature from their description, along with a "2015 Edition" slapped in the title make for an odd marketing choice in comparison to the non-M units..

My bad though.

Huh. It is weird, that Corsair calls this new CXM 2015 Edition because it came out to market in late 2016. I remember us being excited about it coming out.

 

DC-DC is fine not being marketed imo, technical stuff about PSUs is usually not very accessible to the consumer so marketing that this PSU has "An LLC Resonant Half Bridge with DC-DC conversion for the minor rails" doesn't sound very appealing to your average gamer.

Yeah, it's not really necessary to note it (but still good to know and not any less accessible than anything else in the tech specs IMO), the thing here is that they DO have a "The LLC resonant topology with DC to DC ensures complete compatibility with all modern day PCs." line on all their non-M CX models.

[Guest]

The lower wattage CX-M's don't have DC to DC.  Only the 750W and 850W.   They're all double forward.

 

The CX does have DC to DC.  They're a good year or so newer than the last generation CX-M.

 

Except the ones labeled "2017 Edition", of course.  Those have all the FETs upgraded to Infineon because the Chinese FETs kept blowing up inexplicably (they were operating within spec).  

 

The CX-M could use a refresh to LLC and DC to DC so it matches the non-M version.  I've been trying for over a year.  But the cost adder of that, plus the cost adder of it being semi-modular, brings it to the cost of Vengeance or even TX-M.

They were ready in late 2015, and appeared in stores in February 2016: http://www.orionpsudb.com/news/new-dc2dc-eqiupped-corsair-cx-units-appear-at-newegg http://www.jonnyguru.com/forums/showthread.php?t=13055

But... they do... That's what the whole refresh was about. CX-M 450W, 550W, 650W are double forward with DC-DC. https://i.imgur.com/PHLhbQP.jpg

Haha..  You're right.  I lost track.  It's just double forward instead of LLC.  Too many lines to keep track of.

 

Ok... So CX and CX-M both have DC to DC.  CX is an LLC topology and CX-M is double forward.  

 

I think the only Corsair right now that doesn't have DC to DC is VS.

The CXM is the same as Veangance with a shitty protection chip and not full "Wapanese" Caps...

Seems that way, yes.

But there are the first units with DC-DC for the system integrator level...

I'm curious as to why you think a WT7502 is "shitty".

 

It doesn't have OPP, but that's managed by the PWM/PCF IC.  It doesn't have OTP, but that's handled by the fan controller.  It doesn't have OCP, but it's a single +12V rail PSU with DC to DC, so OPP takes care of that.

Because it has no dedicated +12V input pin, only VCC...

 

Why doesn't nobody (except for Delta) make their own (digital) Supervisiors??

And why aren't there many +12V Only Supervisior Chips available?? (well, they exist - but only in the larger 14pin packages...)

 

Most 3rd party types don't seem great and have bad UVP or OVP trip points...

wasn't it the PS223 that has +12V UVP at around 8,5V??
