The Power Supply Unit tier list Discussion thread

[chimera201]

Wow, that excel sheet will really be useful. Especially with the sort functionality. But it will be a tiresome task to add all the models out there. I did suggest sometime back that you can create more tiers if you want to , don't have to stick with the Newegg's 5 tiered list

 

[jonnyguru]

Interesting, what criteria you using for your tiers?

Seems a bit excessive... Since you will probably need to add a few tiers for bad units, you have put the CX series in tier8, which I would say is middle ground when it comes to reliability.

Actually, the CX is tier 6. The tier 8 CX you're seeing is the first generation with the all Chinese capacitors.

Right now, that seems about right too me. On this list, it doesn't seem like "middle ground", but I've only had time to put in these six brands. If I put in more brands and those brands have questionable quality, I'll add more tiers. The nice thing about doing it in a spreadsheet is that it will be easy to edit.

Once everything that's already out there is added, maintainence should be pretty easy. I'm just going through RealHardTechX's list and copying every make/model over for starters.

Ah i see, thanks for the clarification. Guess its still a very early version. Thanks again!

What is the B2 doing in Tier 4, Shouldn't it be in tier 3 or 2?

What is the B2 doing in Tier 4, Shouldn't it be in tier 3 or 2?

EDIT: Sorry.... Got Evga's standard "Bronze" unit confused with the B2. B2 is decent (not tier 2.. almost 3), but certainly not as bad as the standard Evga Bronze units.

[strike]Oh god, no. We're talking about an HEC (not very capable OEM with mediocre soldering quality) built Bronze unit with a sleeve bearing fan and no Japanese brand caps. I have second thoughts about it even being in tier 4, never mind tier 3 along sides the likes of Seasonic G Series based units and FSP Aurum. And tier 2? Seriously? Along side CWT CSH, Seasonic XP2 and Super Flower Leadex? That's crazy talk. ;-)[/strike]

 

[cyruseternity]

Can you please add seasonic s12ii 520w and m12ii 620w into the list...
Thanks

 

[jonnyguru]

Read my previous comment. I haven't gotten that far.

I guess the idea that the EVGA B2 series "may even reach silver efficiency levels" has confused some people about it's overall quality. Since the efficiency level has already clearly been established as not being a good criteria for selection, you might want to remove that statement from the original article simply to avoid misunderstanding about the unit. Also, the following, which is the conclusion about the EVGA B2 750w doesn't seem to indicate a poorly built unit that belongs at the bottom. At least I don't think that's what most people would take away from that. I could be wrong, but a 9 out of 10 wouldn't indicate to me that it belonged at the bottom of the pile.

Summary

EVGA's 750 watt B2 unit is a pretty solid product for you budget minded folks out there. It's not the best thing I've ever tested, but it doesn't need to be. When you're targeting a unit at the budget crowd, some things have to be sacrificed. In this case, EVGA tossed out a little non essential performance in favor of giving you a decent and reliable product at a price that won't empty your bank account. This is exactly the kind of unit the market really runs on. Yeah, it's nice to dream about buying one of the more impressive Leadex based units, but if you can't afford one of those you still need a unit that's solid and dependable enough to get you by until you can get one of those beasts.

So far, EVGA's done a pretty good job at giving Corsair, Antec, and Seasonic some real competition in the marketplace, and they haven't made a single misstep since they partnered up with Super Flower. This unit is going to do well for them.

The Good:
•beyond excellent minor rail ripple suppression
•excellent 12V stability
•semi-modular
•80 Plus Bronze certified, but actually did Silver
•very good 12V ripple suppression

The Bad:
•some soldering related issues unusual for the OEM

The Mediocre:
•strictly average minor rail regulation

B2 is Super Flower.

Right now I am giving the tier list a complete overhaul to prevent such anti-spam issues from appearing.

No, this thread will be for discussions only from here on out. When the tier list has been finally created, there will be a link linking the new tier list on the front page and on the new list will link this page for discussion. A new megathread could be in the works if I have the time to do so, but for now, this thread is for discussion, as no changes can be made for now.

Just wanted to thank you for this list. I went ahead and bought a Seasonic X-series 750W psu. This thing oozes class.

B2 is Super Flower.

That's right. Only the "B" is FSP and the "Bronze Series" is HEC. I've been staring at the spreadsheet so long that the numbers are bleeding together.

So the HEC based Evga IS where it belongs: tier 6.

I still don't think a Super Flower Golden Green deserves to be higher than tier 4. Tier 4 isn't horrible... BECAUSE THERE'S CURRENTLY NINE TIERS!!!! 😛

It's in good company in tier 4 with the likes of the Antec Earth Watts and the beQuiet Dark Power Pro 9.

Thoughts on the best GPU this PSU can handle with an Athlon X4 860k system:

Setney BXP 600

An ATI Mach32 VLB.

Seriously... I hope you didn't already buy that thing. It's a non-PFC PSU with only 240W on the +12V rail.

TWO HUNDRED AND FORTY WATTS!!!!

That means this "600W" power supply has less power available on the +12V rail than many 300W power supplies.

 

[bobybrown123]

Haha, Happens to the best of us.

 

[RazerZ]

I didn't buy it, I was trying to help a person with that PSU for an upgrade. 230W...wow.

I'm a big fan of the Golden Green. I use it in many builds including my own. And because I am a big fan, I feel that it should be higher tier 😛

 

[bobybrown123]

Shouldn't the Supernova B2 be in tier 3 if the G1 is? Or should The G1 be lower, I thought the G1 was of lower quality then the B2? The G1 750w is in tier 3 on the new list, while it is also in tier 3 on the old one, while the B2 is in Tier 2 A?

 

[Darkbreeze]

I think some of you are confusing the tiers of the dottorent tier list and the tier list jonny is currently working on.

 

[Lutfij]

It has already been stated by dottorrent , the current tier list will be revamped to include a larger tier basing and ofc a better management of units within each tier.

As of now we are waiting on a direction(post holiday season) but until then this thread would be primarily a discussion for PSU's thread

 

[MasterMace]

Aw mann just got an EVGA NEX 750B1 and it's considered a Tier 1 PSU NOT IDEAL FOR OVERCLOCKING? That sucks considering I just got a whole z97 setup with a liquid cooler and stuff, thinking I could overclock...what's wrong though considering I have Pentium G3258 and a mind for the GTX 970??

I saw that the PSU got some good reviews too, over at High Tech Legion too... http://www.hitechlegion.com/reviews/power-supplies/41110-evga-supernova-nex750b-power-supply-review?showall=&start=3

You can safely SLI 970s on 650w easily. They use very little power, for how high end of a GPU they are.

It's very dependant on what CPU they use and what overclock they are running. An i7 4790k might average 124W stock, 142W overclocked, but they peak at 350W. An 970 OC will peak around 245W. I wouldn't put that into a 650W, that's asking for trouble. I would put it into an 850W.

I have used Seasonic X560, it was broken after 2 weeks of usage. RMA got a new X560 and it was broken again after 3 weeks. I have used FSP Blue Storm works fine for almost 7 years.

That looks more like a motherboard issue.

Hello,

If that is a motherboard issue then why when I replaced the x560 with the new one it works perfectly fine for 3 weeks ? it should not have worked since the broken one is the motherboard. Sorry if this is a dumb question, I am no expert at this stuff.

Thanks

 

[chimera201]

Thanks for adding the Antec VP(230V only) in your sheet jonnyguru !!! People here unknowingly recommend the Antec VP(230V) series over the Corsair CX series. There is a general misconception that any Antec PSU is better than Corsair CX series

 

[dottorrent]

Tier list is half way there. Still settling on what to describe each tier as. I'm also going to add which OEM the PSU platform is from for an easier understanding.
