The Power Supply Unit tier list Discussion thread

[zeyuanfu]

It's okay.
The extra 1-2% of efficiency is NOT worth the 50< euros more you pay. Even if you are a power consumption-conscious guy, it would take ~5-15 years for the PSU to pay for the difference between it and the g2, and by that time, I'm pretty sure you'll be needing a new PSU.

Many thanks!

Is Evga supernova p2 not worth the Price over evga 220 g2 0750 xr ?

Sorry to ask kind of the same Again, but i am almost clueless, and i rather have a Little to mutch power than a Little to less, and my old PSU was 850W, so shouldnt the new be higher? Sorry!

Wait wait wait, you are considering buying one GTX 980 and you are looking at a 1500w power supply? That's crazy. Even with 4 x GTX 980s in 4 way Sli you only need 1150 watts. A system with a single GTX 980 only needs a 520w power supply.

Don't these seem to be conflicting results? How can it be BOTH exceeding the +12V ATX spec and have GOOD +12V regulation?


•Good price/performance ratio
•Tight voltage regulation at +12V
•Handled full power at over 50°C operating temperature
•Good performance in Advanced Transient Response and Turn on Transient Tests
•Silent fan



•Loose voltage regulation on the minor rails (5V & 3.3V)
•+12V and 5V exceeded ATX voltage regulation limits at Crossload 1 test

http://www.techpowerup.com/reviews/Antec/HCG-520/8.html


If these test results are accurate I'm unsure it should be a Tier 2A unit. Maybe 2B?

That's a review from back in 2011 before the Intel Haswell processor appeared. Crossloading, as what would happen in their CL1 test, would not have occurred with the technology available back then.

You wouldn't want to use that PSU in a Haswell build today if you want to use C6/C7 power state support because that CL1 test shows what would happen with that old group regulated design.

And since people looking at the Tier list ARE wanting to use it with current hardware, seems that would indicate it should be on a Tier that relates to use of it with current hardware, which isn't probably Tier 2A. If it can't be used with Haswell I wouldn't want it listed at it's current position I think.

Thanks for the link anort3. I have no idea what a graphic Card use, just assumed a newer GPU would need a PSU with more W than what i have now. I will get the one linked to by zeyuanfu : evga 220 g2 0750 xr and the GTX 980.
then i hope it runs smooth in 60 Hz. 😉

Do you think it`s to difficult to install myself?


Btw. it was "only" 1000W the other PSU i was looking at.

 

[zeyuanfu]

If you're talking about the GPU or PSU, no. There are plenty on videos on Youtube showing you how to do that.

 

[Th4nks]

Yes, i was talking about the GPU and PSU, i will give it a go then.

Thank you very mutch for all your help.

 

[zeyuanfu]

No problem

Silverstone Strider Gold S 1500w should be tier 2b based on this.

Also please make sure to go back a page and read my rethinking of the Corsair HXi based on differing reviews. Thanks dottorrent!

Hello. Is one of these two psus Haswell ready SS-620GB or SS-620GM2? I can't find a solide information...

Only the 750w and 850w versions of the M12 II Bronze Evo edition are Haswell ready, the 620w unit is not. No models of the S12 II Bronze are.

Seasonic has never claimed Haswell compatibility for any of their group regulated design PSU's.

Ty for the answers.

They are already listed in Tier Three.

 

[dottorrent]

Corsair HXi series moved to Tier 2 Class A.

Silverstone Strider Gold S 1500w is with the Strider gold S series found in Tier 2 Class B.

Thank you Anort3 for that info.

UPDATE November 25th 2014

I decided to add a couple of Silverpower units into the tier list since they are still being made to this day. Also, I have added a few PSUs that were announced via RalHardTechX, one of which you won't expect. Can you guess which one?

Another set of units added are some of Super Flower's lower end PSUs. I just thought they have been neglected for long enough.

And now, the moment you've all been waiting for...

Added PSUs to tiers are the following -

Currently un-tiered -

Club3d CSP Gold 750 / 850w
Cooler Master B series v2
Cougar A series
Rosewill Valens series
Zalman GVM series

Tier One -

Super Flower
Golden King series
Golden Silent series 430w

Tier Two Class A -

Silverpower
SP 460w Fully Modular
SP Semi-modular

Super Flower Golden Green / Modular / HX series

Why is Tier 2 split into A and B where everything else is just a tier?

Second question, is there much of a real world difference between a Tier 1 and a Tier 2A?

The tier 1 PSUs have the most modern, most efficient architectures available. Tier 2A are extremely reliable but might be based on older designs with less bling features. I personally like to buy from 2A. I know they will hold up to overclocking abuse, and I don't need platinum/diamond efficiency.

It's kind of silly, really, but changing things around might cause more problems than good. Example: If you didn't know that the list was re-tiered, and you skipped down to group three, not realizing that those were actually the old 2Bs.

If not can you find me one in the 50 under price range please. I am on a low budget and only have 130$. i am buying a 95$ gpu thats on sale and dont have much else Dont worry about shipping!

 

[damric]

The CM RS are cost cutting CWT units, stay away.

Get a Rosewill Capstone while they are on sale, or an XFX. They are comparable price but excellent quality.

I think this article should be added in the list's description.

Most of us use the RealhardtechX database.

http://www.realHardTechx.com/index_archivos/Page541.htm

 

[RazerZ]

I see... that database is easier to navigate through and seems to be more detailed as well.

 

[Deleted member 217926]

The Tom's list is a bit more comprehensive though and has brands that RealhardtechX doesn't bother with. So it is useful sometimes when you need to find an OEM.

 

[RazerZ]

Alright thanks, I'll keep that in mind.
