PSU tier list 2.0

[Darkbreeze]

Nice tier 4.. and i use it with a high end system

There are lot's of people who also use Zebronics, iBall, Raidmax, Thermaltake TR2, Aerocool Strike-X and a ton other others with high end systems. But for every one of them that doesn't have any OBVIOUS issues, there are 9 others that have every issue you can think of, up to and including complete failure or damage to hardware. Now, that VS isn't nearly as bad as most the units sold by those mentioned brands, but the Corsair units have their own set of issues, chiefly, they don't last long and generally start presenting issues between 6 months to a year and a half when used with a high demand system. It also matters how hard it's pushed and how long typical high load sessions are.

The fact is, in some markets, you're not likely to find anything better without paying a very steep premium to import one. Usually though, there are some other models available that offer better quality for a similar or slightly higher price.

Just because far too many of a given series are failing, does not mean all of them will. Some people do get lucky.

And a busted watch is right 2x a day. Considering there are 86,398 seconds in a day where that busted watch isn't right, you are playing very longs odds of being a lucky one in a search for a 'good' VS

 

[Darkbreeze]

But as long as you already have it, and it's working fine, it's fine. If you begin to notice any unusual behaviors or errors from your hardware, I'd look to the PSU before searching out other issues.

Can't choose between the FSP Aurum S 500 and the Seasonic ss500bt eco(a bit old)
Where does the seasonic one fit ?

 

[Darkbreeze]

Neither unit is incredibly good, but the Aurum S 500 reportedly has a significant noise problem (Voltage noise, not audible noise) so I think the Seasonic would be the lesser of the two evils even though it's not one of Seasonic's better offerings and if this is for a gaming machine, I wouldn't even think of using either of those units.

 

[chanuka]

Yes, it's for a budget gaming machine. Powering up an Asus R7 260X

 

[Benjiwenji]

That's not accurate. These are from both RealHardtechX and Tom's hardware's "Who's who in power supplies", and both reflect the same thing, which is that they are FSP and HEC.

If we are still discussing the EVGA NEX 750 G (120-PG-0750-GR) and 750 B (120-PG-0750-KR), then they are both manufactured by FSP according to your images from RealHardtechX.

Furthermore, the NEX 750 G (120-PG-0750-GR), which has gotten decent reviews and uses Japanese caps, was moved from tier 3 to tier 4. I was just asking for the reason for these changes.

 

[tiny voices]

Because it has pretty terrible voltage regulation and ripple, and fails 80+ gold specs.

This is all outside of my expertise, so I am just learning as I go. With that said, can you point me to reviews that support your claims?

There only two reviews that I can find on the EVGA NEX 750 G (120-PG-0750-GR). While they both made complaints about the ripple, they ultimately stated that it is still within acceptable range.

Here are the load regulations and ripple tests:

4.45% voltage swing on 12v rail? NOT OK.

Bottom line is that is is an awful PSU for the money. IF it was $49.99 no rebate, then it would be ok, but for the price it is listed at, there is absolutely no reason to even remotely consider one.

The 750B and 750G are both discontinued models. I was referring to the B1 and G1 series, which is what is currently being sold.

Well to be exact, it had a 3.76% swing at 750w, the advertised max load. It is a bit high, but Isn't the standard +/- 5%?
That's why it passed, and the same review that collected the data gave it a score of 8.1

Here is where Shilka borrowed the data:
http://www.techpowerup.com/reviews/EVGA/NEX750G/5.html

Also, on another review, the same unit was tested to have within a 3% swing on the 12v rail.

Here it is,

Furthermore, look at this Thermaltake Toughpower XT Platinum 1275 W, a tier 3 PSU on this list. It has a 3.09% swing on its 12v rail too.

Yes, they are discontinued. However, tiny voices was referring to the G unit and so was his link on its voltage regulation swing.

Furthermore, if we are talking about the G1 (120-G1-0750-XR) and the B1 (110-B1-0750-VR), then they are still manufactured by FSP. I also can't find any reviews on either one. Thus, my question remains, why they were they downgraded from tier 3 to tier 4.

Take a look at the Crossload 1 test. The EVGA SuperNOVA NEX750G's +5V rail goes out of ATX12V specs due to the PSU's use of an old group regulated circuit design. The Thermaltake Toughpower XT Platinum 1275 W doesn't go out of spec on any of its rails during both Crossload tests due to its use of a modern DC-to-DC circuit design.

What are you, the PSU police?

They were downgraded, most likely, because either Dottorent felt that's where they belonged, some factual data supported the move or because we've seen high numbers of them with premature failure/problem rates when used with gaming or overclocked systems, just like the CX units. Do you happen to represent FSP in some fashion?

Thanks for pointing that out. My response was specifically to address tiny voices' comment, so I didn't mention it.

However, I am very new to this, so can you tell me the significance of the result on cross load test and the 5v rail in terms of real world performance?

No, I don't know what a PSU police is. However, I am looking for an understanding of this subject. Thus, I ask questions. I don't mean to offend you by being curious. If there is ever a question that is beyond your knowledge, as it might be the case here, then you can simply leave it to someone else to respond instead of speculating my intent. With that said, I appreciate your contribution to my curiosity thus far.

 

[Darkbreeze]

Nobody is offended. I'm just giving you hell. Messing with you. Getting your panties in a bunch. Playing around. See. Just an honest heckling. No worries. And just because I don't talk like Jonny or k0888, using terms most members wouldn't understand, doesn't mean I'm in over my head. You haven't the slightest idea at what level of expertise I'm comfortable with. I was just casually messing with you, as I do with everybody here, but now you want to go and get all personal. I think I'll leave you to it then so it doesn't get to point where somebody does become offended.

 

[MarkW]

Darkbreeze is the PSU Police. We even gave him a badge that looks like this...

And then we gave him a very special gun too...

 

[Darkbreeze]

^^^^Yep, that's mine.

And I am sorry, as I am unfamiliar with the norms on this thread. Here why I am asking these question, I bought a 750B this summer. It is that simple 😛. I also have the xfx core ed pro 850w, both of which I am pleased with.

 

[Keller1233]

Hey, I know the Corsair RM750i is Tier 1, but I wanted to go for the slightly cheaper, less wattage RM650i. But thats not on the list. Should I assume, that since it is the same product line that it is Tier 1?

EDIT: looks like tier 1, see review: http://www.eteknix.com/corsair-rmi-series-rm650i-fully-modular-power-supply-review/9/

same design as the RM750i

 

[stavrosmast]

its ok my corsair vs650 is tier 3 and its still good

However, I am very new to this, so can you tell me the significance of the result on cross load test and the 5v rail in terms of real world performance?

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.
