The Power Supply Unit tier list Discussion thread

[Rexer]

Hi guys.
Apologies on my absence on the tier list, I have been incredibly busy. The tier list will be updated ASAP.

I am still not sure about the RM series from corsair . . are they good ? . RM series is listed in tier 2 class A . but they are not that good as reviewed . . I am also looking to buy the 650w version . . what's your thoughts ?

Most RM PSUs are excellent choices. The 650w Model will be moved to Tier 3, until further notice. It's a decent choice, as it is silent, got a good amount of cables and is built to a high standard from Corsair. I would stress though, that the Seasonic G-650 is another £5 - £10 ($8 - $15) more expensive, but is of higher quality. That would be my pick.

my friend has RM750 and it has real temperature issues . . it has shutdown 3 to 4 times on high temp like almost 40degree . . that's why i haven't bought this yet . . so the rm650 is in tier 3 and the other models are still in tier 2 . . any explaination . . . ?

I own a Corsair RM750 I just pulled out of my game computer and threw in the closet. I had gone around in circles trying to figure out what's wrong with my rig. I built it 9 months ago and it's been a real heater. Great in the winter, toasty in spring. It couldn't take the summer and began to black out and finally kacked at the end of July '14. I began looking on websites here and there and discovered Corsair was having a recall on the RM 750, first 4 numbers in serial numbers below 1341. The recall is due to a possible thermal problem. The first four numbers of my serial # are 1333.

I was gonna buy the SeaSonic X Series 750 but changed my mind on the advice of a friend. After several hundred dollars spent on suspect parts and a few misdiagnoses, I wish I'd never strayed. But I'm not saying this as a slam on Corsair where this misfortune was just the 'luck of the draw'.
Fact is, you're probably right about waiting till it gets to a higher tier because Corsair does invest in quality with some regularity, enough to dispute a moment's reflection of mistaken calculated values.

The problem with the RM in my opinion was the fact that Corsair used two different OEMs for the series. Their old standby CWT makes the 450w, 550w, 650w and 1000w versions and Chicony Power Technology makes the less than stellar reviewed 750w and 850w models. The good news is that Corsair knows the first Chicony models were terrible and now Chicony has released an updated version. There are no real reviews of the updated models yet so I still will not recommend them until I see a few.

Just wondering, why was the seasonic M12II tiered at tier one while the M12II bronze was tiered at tier 2?

There were only two models in the M12II Series (SS-430GM and SS-500GM), both only 80 PLUS standard efficiency units that were discontinued years ago.

It should have been labelled M12II Bronze SS-650AM, SS-750AM and SS-850AM models. The point is moot, anyway, since the M12II Bronze Series has been discontinued and has been replaced by the M12II Bronze EVO Edition Series.

 

[blackfonzy32]

In Tier 2 Class A you have the corsair TX / TXM series, however, I would like to replace my shitty coolmax with the TX850 V2 that's on sale on newegg, does the V2 make a difference or should i look for something else because i dont see V2 anywhere on here

 

[jimthenagual]

If anything, I'd say the v2 lineup is a little better than the original TX. The V2 are made by Seasonic, whereas most of the TX originals are made by CWT.

[Deleted member 217926]

Yep, the TX V2 were all Seasonic made and the best of the TX series. Discontinued now like the whole TX line but I'm sure some places still have them in stock.

How would The Cooler Master G750m rank up in this?

 

[Deleted member 217926]

How would The Cooler Master G750m rank up in this?

No real reviews of that exact model exist but it's made by CWT. Here is a review of the 550w model.

http://www.techpowerup.com/reviews/CoolerMaster/G550M/11.html

CapXon capacitors on the secondary alone are enough for tier 3. It's a value unit and should be used as such.

 

[Deleted member 217926]

Looks like the Antec Edge series are based on the Seasonic G platform making them very solid tier 2 units.

750w review.

http://www.hardocp.com/article/2014/09/02/antec_edge_750w_power_supply_review/9#.VAZklWNuW_E


Probably safe to list the entire True Power Classic line as tier 2 as well. Same platform.

750 review.

[zeyuanfu]

Where would the EVGA SuperNOVA 850 B2 go in this list? I am considering to purchase it.

 

[chris987]

not a leadex platform like G2,P2 but based on the Super Flower platform found in Rosewill Capstone. not a flawless unit but still a great one. Tier two class A i would say. here is the review!

http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=393

 

[zeyuanfu]

So EVGA's 850 B2 is just a 750 B2 but with more wattage?

 

[dottorrent]

Essentially, yes. The B2 series uses the SuperFlower Golden Green platform. It's far better than the old FSP ones.

 

[Dark Lord of Tech]

The B2 , G2 , P2 , and T2 are all Super Flower made units , much better quality.

They are also single 12v + rails and the FSP models are multi rails.

Can you fix the Zalman PSU`s ?

I may need to buy a budget PSU depending on my budget and there are these options I see;

Zalman ZM 400 LE sells for 40$,

Zalman ZM 500 LE sells for 53$ but I don`t need high wattage anyway,

Zalman ZM 500 LX sells for 62$,

Zalman ZM 600 LX sells for 69$ but I don`t need high wattage as I said before :lol:

Corsair VS 450 for 55$,

Some thermaltake Litepowers.

Anyway, I am thinking that the VS 450 is the best option. The list says Zalman ZM series under 1000w is Tier2 A but the same list says ZM Series 850/1000W is Tier3.

So according to the list, any PSU from Zalman which is under 1000w is Tier2A with the expection of 850w units being both tier2a and tier3. :lol:

Edit: Also I am not in `Murica, I`m in Turkey so I can use the VS 450.

Fixed. The VS450 is a decent budget unit. Better and more honest than the cheap rubbish you'll find.

Uhm, thanks for your efforts maintaining this list, its very helpful but, its not fixed?

Let me try to help you..

There are Zalman ZM LE series which I think is the cheapest and neither features Active PFC nor 80plus rating.

There are Zalman ZM LX PSU`s with security features and Active PFC.

ZM APS,ZM RS,ZM ST,ZM HP,ZM GT,ZM GS II,ZM GLX,ZM GV,ZM GVN,ZM FX.

What the hell? I counted 12 PSU series. Holy *****. I think theres more.

I suggest you put all Zalman PSU`s to untiered now and work your way one by one.

That has to be hard

What the heck is Zalman ZM Series? There is no such thing as ZM Series from Zalman. All their PSU model numbers start with ZM and not series.

What tier would you rate a corsair rm 1000w psu

 

[Dark Lord of Tech]

RM series uses poor capacitors , I wouldn't touch them.

 

[DHFF]

didn't they issue a recall on those units earlier this year?

 

[Dark Lord of Tech]

The 750 and 850 were recalled for thermal issues.

They aren't good supplies.

I think Corsair better get their act together before another RM unit is released.

It doesn't actually matter. There are few reviews for their units, so it makes sense to do this. Unless some professional reviews sprout up for their newer units, then I'll start updating them.
