Stay away from Cooler Master psu's. Really !

Hi.

I know this is actually the wrong section but still would like to have it here if allowed.

I really wanna warn everybody who didn't know this yet ( not the Tom's members obviously ) to stay away from Cooler Master ( and other crap ) power supply's.

I had the GX750W. This stupid unit gets pretty hot and dispenses the hot air in to the case. :ouch:

When playing games i reached gpu temps of 69C ( before i put in 3 case fans around 72-75 ), all fans ( gpu, cpu, psu, case ) sounding like a jet plane. ( really loud and obnoxious )

Also when playing games i had really terrible coil whining, which was increasing over time, from the GTX560Ti.

Yesterday i put in the new Corsair GS700 and i can't believe my eyes and ears. Running the same game the gpu temp doesn't get higher than 50-55 !!! :lol:
Almost unbelievable.

Without even one fan really revving up, my system is more quit now playing a game than when it was with the CM when i was doing nothing.

Don't wanna know what mu cpu temps were, seeing the psu blew the hot air directly on the cpu cooler.

Cooler Master should be better called Heating Master :pfff: :pfff: :pfff:

And maybe best of all, almost no more coil whine from the 560. Finally i can play a game without squuuuuuuuiiiiiiiiiiiiiiiiiikkk all the time. ( it's still there but almost unnoticeable )

This is the best upgrade i have ever done, love Corsair. 😍 So happy i can cry. :wahoo:



P.s ; i know i don't need 700W but i do like headroom and i wanna sli in the future maybe when i buy a new mobo. ( and i like the led lights 😛 )


 
You should have sent it in for warranty replacement, obviously it had issues.

Coolermaster makes some very highly rated psu's since they aquired PC Power and Cooling, the Silent Pro series is very highly rated.

Almost all companies sell junk psu's, even Corsair.

FYI, neither Coolermaster, nor Corsair actually make power supplies.

The GX750 is made by Seventeam.

I like to stick to psu's made by Seasonic, Delta or CWT.

The GS700 is made by CWT.

OCZ aquired PCP&C, not Coolermaster
 
I know, most are Seasonic made anyway if i remember right.

And, sure they probably make some good ones to, but this particular one is just crap. ( and lots more of them ) Not my sole opinion, just google reviews for that piece of junk. I read one from Guru i think and it wasn't good, ripples, noise etc.

And those numbers and sound experience don't lie. I mean ; who in heavens name makes a psu that blows hot air in to your system anyway :pt1cable: ???

No Coolermaster psu's are made by Seasonic. And I have never seen a psu that blows air into the case, I think your confused.
 
Cooler Master PSUs tend to be pretty crappy the decent ones aren't extraordinary for the price.The Enhance models are good. All of the Silent Pro series are quite good.The rest i wouldn't even let be in my house just garbage.
 
Yeah, right.

I know you always like to be negative ( specially towards some ), when i saw that you reacted i knew it was gonna be something bitchy, but really ; do you think i'm that stupid that i can't feel the difference between air going in or air going out ????

I know i'm not the most computer saffy guy around here, but only a real and total messed up idiot could be confused about that. Even an ape can tell the difference.

A bit said and offending you have to make comments like that to get your point.

Are those temp readings and the fact that it is quit as a Sunday morning also "confused", really my friend you are way wrong here.

Conclusions

Cooler Master GX 750 W looks like a good option for users looking for a mainstream 750 W power supply, however it has a major flaw that prevents us from recommending it: noise level at +3.3 V and +5VSB outputs were above the maximum allowed when we pulled 600 W and above from this unit. High noise levels overload and can even damage components on your computer.
 
do you think i'm that stupid that i can't feel the difference between air going in or air going out ????
No
The only way for it to actually be drawing air in is if the fan were reversed, easy to tell, are you looking at the concave or convex side of the fanblades ?

Blowback is another story
In order to help direct air over the components in a psu with a 120mm fan a baffle is attached, this can cause blowblack that makes it seem as though the psu is acting as an intake rather than an exhaust

It's an issue that's been known since they started doing it, hasn't stopped it from being done, and when done properly is basically un-noticeable
 
Yeah, the do NOT make psu's that draw in air. A factory mistake with a reversed fan, possible, maybe.

If you have so many exhaust fans in your case and no place for fresh air to come it, then it could possible for air in anywhere it can get it, but it would have to be a lot of exhaust and a nearly airtight case for it to passively pull air IN from the psu.

The easiest way to see that it's not pulling air in, is to try to stick a piece of notebook paper to the back of the psu, if it sticks, it's sucking in, if not, it's exhausting.
 
This is my issue with CM. SOME of their PSUs are good, really good even. Others are as you found out not worthy of even being in your garbage bin. I'm not going to take the time to learn the good ones from the crap ones. This is why I say Antec, Corsair, Seasonic, or XFX when I tell people to get a PSU. Sure there are other good units out there. But when I say buy one of these the odds are high that the buyer will get a good unit. (unless they buy a "VP" model Antec.)

FSP, Kingwin, OCZ, PCP&C, and others make good ones. But I can't remember them all.

Edit: I won't even let Athena power or Diablotek units onto my property. Don't even think of bringing them by...

Was going to mention that, just can't imagine anyone doing it, would be like trying to use the PC as an air filter for the room :lol:
 
I have no doubt that some CM psu's may be bad but no more than any other psu's on the market.

I totally agree though...I stay away from CM psu's as a rule of thumb...have had a few blow on me over the years...Corsair makes super nice psu's...have three Corsair psu's (750W in my main machine [sig below], 550W in my HTPC, and a 550W in my NAS) that have been running practically 24/7/365 for the past few years and the psu has been the least of my concerns.

I have to admit tho that CoolerMaster makes excellent cases!

.Corsair doesn't make PSU's :heink:
 
HardwareSecrets reviews (AND an interview that Gabriel Torres had with them) have made it clear that CM is guilty of willful consumer fraud. There should be consequences for that, which is why I consistently recommend against any product they offer, no matter how good. Fortunately, in every segment where they are found, they have competitors offering similar (or better) products at similar (or better) prices.
Of course, plenty of competent technical reviews have shown many of their PSUs are little better than junk, but I wouldn't buy a Silent Pro either; not until they clean up their act.
 
@ Geek ; Used cigarette smoke which it sucked in from the back. 😛

@ Geek & Delluser ; Never said all the fans were sucking out did i ? 2 small fans ( front bottom ) in, 1 big one out ( back middle ). This plus the cpu cooler sucking air in from the side from a hole in the side panel ( 20x20 cm )

Even when i'm wrong with the air stream ( and therefore a real retarded idiot ) how do you smart guys explain the very big temp difference from the gpu and probably cpu then ????

Anyway, love you guys, when someone comes on Tom's stating he has a Cooler Master psu everybody is rushing in to say they are crap and he should buy an other one ( learned the word Crapper Master here ), when i make a statement about it almost everybody rushes in to say they are great. WHAT EVER ! :kaola: :kaola: :kaola:

I know i am very happy with this one and will never buy a Crapper Master again regardless what ever you say, really don't care.

Thank you.
 
Before I had any idea about computer components and brands (when I first started looking that is), I found it hard to trust a company that declares themselves the master of anything right in their name lol.

Corsair rebrands PSUs...
Oops...pardon me, maybe my post would have been met with better approval had I stated "Corsair rebrands some super nice psu's"...regardless of the semantics and splitting of hairs, Corsair sells some reliable, quality made psu's for their price point...and to the OP's point of this thread CoolerMaster psu's are less reliable.

 
Corsair and Antec psu's are nearly all made by either CWT, Seasonic or Delta, all of which are good brands.

None of Coolermasters psu's are made by these companies. I think they should stick with mastering coolers.
