PSU tier list 2.0

[tiny voices]

No one said you messed up buying that PSU. Chill.

All we said is that due to the fact that it is NOT Haswell compliant and based on an older design, there are better units. It is a good unit, that is for sure, it is simply long in the tooth.

 

[Feliks]

Well, ok, so its an older model, and does not support C6 states. I am not using it for a laptop. In fact, probably nobody on this planet is.

And my system is almost never idle. I run Folding@Home in the background, except for when I am gaming.

And what power supply did I buy back in May of 2014 when I built this system? I went to Amazon to pull up the old orders I made at that time. Result? Seasonic M12II-850 BRONZE ATX 850 Power Supply. And yes, I have a nice little Haswell I5-4670K CPU too.

It works. It works well. And I have absolutely no regrets about having this power supply. It has performed flawlessly for me, and I fully expect it will for many years to come. After all, this is a Seasonic unit. Old design or not, it is still a high quality power supply.

Good for you. But just keep in mind as people say your power supply is old design, etc. People say the same things about mine, including you, therefore tiny voices (since I haven't hooked mine up yet) could say the same thing about reliability, etc.

Honestly I think Power Supplies is one of the most opinionated/controversial threads on here. I can get told 5 completely different answers to one question. I'll have to go with the people who have actually bought the parts I am buying and have the experience though.

Thanks everyone :')))

The 850w M12 II Bronze Evo does support Haswell low power C states. It's not the same group regulated platform as the lower wattage models you like to recommend.

I have used this $50 XFX 550w probably no less than two dozen times.

The Crossload 1 test, in the TechPowerUp.com reviews of the EVGA SuperNOVA NEX750G and Thermaltake Toughpower XT Platinum 1275 W, places a heavy load on the minor (+3.3V and +5V) rails and a light load (~ 2 Amps) on the +12V rail.

TechPowerUp.com has since modified their Crossload 1 test to match the testing methodology that Intel uses for Haswell Ready (a.k.a. C6/C7 processor power state) testing (i.e. 0 ~ 0.1 Amps on the +12V rail).

It's almost impossible for PSUs that use a group regulated circuit design to pass this test without one or more of the rails going out of ATX12V specs. When one or more rail goes out of spec it may trigger one of the PSU's protection circuits causing the PSU to shut itself down.

Any PSU that claims to be Intel Haswell Ready without being able to pass the test, according to Intel's testing methodology, is lying.

On a good PSU no rail should ever go out of spec no matter how it's loaded since it could lead to damaged components.

The +5V rail is used to power some semi-conductor chips on the motherboard, SSDs, hard disk drives, optical drives, some powered USB devices, ..., etc.

Thanks for the explanation. I am using the 750B to power an AMD FX 8370e, so does that mean it is still reliable given that I am using the old AM3+ platform and not a Haswell?

You don't need to worry about C6/C7 power state PSU compatibility with an AM3+ platform.

So my friend bought a Force 450W psu how long do you believe it will last? 😀 He will replace it on probobly january

 

[Darkbreeze]

You mean it's not dead yet? That must be an exceptionally good example of an exceptionally bad unit. ANY Supercase PSU, Force models included, are very low quality and most probably even dangerous to have in any system.

 

[stavrosmast]

Tomorrow his build will be finished.. Lets see how long it will last.. 😀

 

[tiny voices]

I wouldn't even bother with it. Why risk frying a new PC with it?

 

[stavrosmast]

Cause he doesnt have enough money for a better one right now..

 

[tiny voices]

That doesn't make using it a good idea. If it was me I would save the money for a proper one and THEN use the PC. If he doesn't have enough money for a new PSU, he DEFINITELY doesn't have enough money to build a new PC when this junk PSU fries everything.

What are the specs of the PC?

 

[stavrosmast]

He built a junk pc it would be better to get a ps3...

8gb ram, 450w force,amd a10 ****,asrock mb,stock cooler,

Next year he will buy new psu and dedicated gpu if his build wont be fried...

 

[RCFProd]

With that build the PSU won't have to work hard, so maybe it will be fine.

 

[stavrosmast]

We will see for how long,... 😀

+1

With a SUPERCASE PSU? I doubt it.

Breaking news! PC burns down house!

In some strange, and unexpected news, JonnyGuru recently did a review on an old EVGA NEX 650G1.... At the bottom of the pile of units. He gave it an 8.5 with build quality at 9.5. Now this may seem like a four leaf clover of a unit, but I shall investigate further.

 

[Darkbreeze]

Isn't it the same platform as the 750 G1?

 

[Benjiwenji]

😵 Jonny G must have heard my whining

 

[Darkbreeze]

I doubt it, unless you posted something on his website. He pretty much avoids us like plague these days. It seems he has a rather low opinion of us, in general. Might have something to do with all the well earned Corsair bashing that happens here on a pretty regular basis. Don't get me wrong, I like Corsair memory and most of their cases are at least fair, and some are very good, but I wouldn't pay money for any of their power supplies, not even the higher end models.

 

[MarkW]

I agree. However, when I learned what Corsair was doing with their lower end power supplies, and read what their marketing materials was saying, and understanding that the problems originated from the choices they intentionally made to use lower quality parts, it has seriously made me suspicious of everything they make now. If they did it with something as important as a power supply, what else have they done it with.

So for me, what I thought was an overall high quality range of products a year ago, I would no longer even consider anymore.

 

[Benjiwenji]

Never had the pleasure of using one of their products. They seem to be a fairly popular name brand, but none of their products seem to excel at their particular field, with emphasis on their PSUs.

 

[stavrosmast]

i have both corsair ram and psu 😀

 

[tiny voices]

I skip Corsair now-a-days. Shoddy business models are not my friend. I do like my Corsair case and mouse but I will not be doing business with them again.

Also, the NEX 650G Johnny got was 1000% cherry-picked. I promise.
