The Power Supply Unit tier list Discussion thread

[toyftw]

Hi - It's a good project, IF; The reviews upon which the tier decisions are made are in fact by thorough and competent review sites,
and not say sites that Gabriel Torres refers to in his article, why 99% of PSU reviews are wrong:

Each brand you should write bold for, it would look cleaner

E.g.

This is now:

Corsair-
CX Series
HX Series
BS Series:3

You can make it this:

Corsair:
CX Series
HX Series
BS Series:3

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 . . . ?

Tier one - The highest quality and most stable PSUs available on the hardware market today. Highly recommended for any situation -

This statement isn't accurate because of the discontinued/obsolete models listed.

Antec Signature series <===== Discontinued

Enermax Revolution82 <===== Not listed anywhere in Enermax's current or legacy product lists

Sapphire Pure series <===== Sapphire is out of the PSU business

Seventeam ST series (greater than 600 watts, SSI, V2.91) <===== There's no supporting evidence that Seventeam should even be in Tier 1. What is an ST series? Every Seventeam PSU model number begins with the ST- prefix accross all (i.e. at least 36) of their series.

SilverStone Decathlon (DA) and Olympia (OP) Series <===== both series are Discontinued

SilverStone Zeus ZF and ZM1200M <===== Discontinued

Ultra X3 greater than 1000 Watts <===== Discontinued - Uses All Teapo capacitors. 7 year old technology doesn't qualify for Tier One when compared to the electrical performance of currently available Tier One PSUs.


Super Flower Leadex Platinum series should not be in Tier two class A. It should be in Tier One. This is supported by unbiased expert reviews.

Super Flower Leadex Gold should also be in Tier One and is supported by unbiased expert reviews.

Have your friend check the PSU's serial number. If the first four digits (i.e. lot code) begin with 1341xxxxx or higher then they should have addressed the PSU fan operation issue.

Serial numbers with a lot code earlier/lower than 1341xxxxx will have the PSU fan operation issue and should be RMA'ed with Corsair.

as he said that it is of code higher than 1341xxxxx . 13423527 ... thats what he told me . . i haven't checked it myself

. . . so the rm650 is in tier 3 and the other models are still in tier 2 . . any explaination . . . ?

Two of the +5V wires aren't working on the 20-pin portion of the (20+4)-pin ATX cable because of the missing jumper/bridge wire on the modular interface circuit board. This means that this PSU shouldn't be used on a motherboard that only has a 20-pin ATX power connector.

Tier two class A
RM series (650w model uses cheaper sec. capacitors) <===== That's just wrong. The Teapo and Capxon aluminum electrolytic capacitors on the RM650's secondary side are considered to be of higher quality than the LTEC's used in the RM750 and RM850. LTECs are considered to be near bottom rung.

I have been busy over the past season, so please bare with me. Plus, most of the reviews I have read of the 650w model do mark it down for no Japanese capacitors on the secondary side. Please bare in mind it has taken me some time to get back to the list. Like I said, I will update the list as time comes.

EVGA SuperNOVA G2 and P2 should be in Tier One and is supported by unbiased expert reviews.

Wish newegg would figure out what the hell there doing and give the tier page again.

BTW upgraded my power supply to this list to Antec HCP 1000w and couldn't be happier thanks for the list dottorrent, i looked everywhere for neweggs list but then ended up going on your list here. Love this power supply.

The EggXpert forums have been replaced with the community forums and the tier list has seem to have disappeared. I made the list, just in case something like this happens.

The list is here: http://community.newegg.com/eggxpert/computer_hardware/f/135081/t/45344.aspx

It still has the obsolete discontinued models in there.

Can't wait to see what Tier the new GXII series will be 😀 Someone hurry up and review it 😀

OE! How did I miss this thread previously.

By the way I am finding my source but I believe the Cooler master Silent M2s should be on tier 2 or T2b.

If you look at the scope shot from Tom's Hardware's own review of the Cooler Master Silent Pro M2 520W you can see that the ripple and noise are outside of the allowed ATX specifications:

ATX allowed maximum DC Output Noise/Ripple:
+12V: 120 mVpp
+5V: 50 mVpp
+3.3V: 50 mVpp

 

[Novuake]

Ah thanks! I remember looking at a review for the 620W specifically. All seemed well with that one. However could be mistaken.

 

[megahmad]

Can you add the Gigabyte series of PSUs? if not all of them, at least add the Odin Pro and Odin GT to the list. I think, based on their reviews, their place is between "Tier two Class B" and "Tier three".

Thanks.

Units reviewed which are older than 2009 are not on the list. The Gigabyte Odin pro and GT is an example of that.

 

[megahmad]

OK Thanks! but when I suggested to add some Gigabyte PSUs, I meant their line of PSUs in general, but I wasn't clear enough and I didn't know that units older than 2009 are not included in the list . Anyway it would be nice if maybe we can add their newer PSUs like the Sumo, PowerRock, Hercules etc... series which are all released after 2011 I believe and all of them have reviews.

BTW this is really a great list, and I refer to it everytime I get a PSU for my customers. (I work at a PC shop). Keep up the good work!
