The Legacy tier list has been phased out now. Please use this thread as the discussion thread now. The new tier list maybe locked out in mid-may as a result. There will be talks with a couple of official moderators to see if the new list will be locked out from discussion.

Thank you all for supporting the list thus far. It does take some long, stringent research to get the list just right. And thank you all for suggesting the changes and updates, which has evolved the tier list entierely, making it look as modern as possible and giving people more reasons to buy a better unit for their safety and reliability as well.

Please click here for the new list.

Dottorrent.

Would it be possible to remove discontinued products? For instance Enermax Galaxy...I'm sure there's some others since the base list is 5 years old. I don't know, might be helpful if someone wants to use this as a reference for new builders if it's all current.

Let me look up which PSUs are discontinued and will be updated shortly.

Done. The spaces took up a lot of space. Shouldn't be a lengthy read now.

Dottorrent isn't this is a straight copy/paste of the EggXpert page here?

http://www.eggxpert.com/forums/thread/323050.aspx

How exactly are you determining what units go in what tiers if they are not on the list? The EgXpert guys use reviews of voltage regulation and ripple and noise. Also while the list is decent it's not perfect.

For instance the Corsair CX series is tier 3 due to cheap capacitors. The CXM uses quality Japanese capacitors and should be tier 2 or 2b.


With a change in format and a lot of time and effort into research I could see a list like this ending up as a sticky. We do have a few power supply guides in the sticky but they are dated. As a direct copy/paste I'm not sure we can use this though. Not with the Tom's name on it.

Let me get some other opinions on what should be done here. I'll be back in touch probably via PM.

Edit: Just saw the date. Is this something you want to try to keep current? If so PM me. For now I am going to remove the Tom's Hardware name from the title.

About the Corsair VS series - it's definitely not on par with the CX series. I think it's one or half a tier below the CX series.

There is only one review of Corsair VS series:
Corsair VS450 Review

The things to note in this review are:
1) Tested in a colder environment. Higher temperatures(40-50 deg C) might negatively impact efficiency,ripple,noise,voltage regulation

2) Tested at 230V. U get higher efficiency at higher voltages

3) I think the reviewer didn't have precise equipment as others do at the time of review.

4)Will never get 80 Plus certification even if it is great because 80 Plus certification labs operate at 115V and Corsair VS series at 220-240V


Also in Tier 1, is that Seasonic S12 II Bronze series? Because there is a separate S12 II series(discontinued)

1 - The VS series is based on the same platform as the CX series and the review seems fine. Low ripple and the same capacitors but a few components were sacrificed to meet pricing requirements. Also the VS Series is for developing countries.

2 - Yes. That is the new bronze series.

 


Where are you getting this information from?

From the reviews and tear downs of the CX Series modular and non-modular models, I've read, they both have the same quality of components. A Japanese 85°C rated primary capacitor and cheap Taiwanese 105°C rated CapXon secondary capacitors.

Moved back to Tier 3. I was right the first time.

Interesting. I am not sure where I saw that but I have been under the impression the CX-M was slightly updated and had fixed the Capxon secondary. I'm not the only one who has been posting that either so it may just be a case of bad info getting out and spreading. I certainly will not post it again if it's not true.

Ko888 I don't know if you have the time or the motivation but I can't think of a better person to head up putting together an official Tom's PSU tier type list. If that's something you would be interested in let one of the mods know. I would help in any capacity I could and I bet SR-71 Blackbird would be glad to jump in.

Dottorrent I have not forgotten you or this list. I have been busy and had some family stuff going on for the last week and a half or so but you would certainly be involved in getting any official list going if you wanted to be.

Hey, I'm always looking for people to help improve this list. Always open to suggestions and improvements.

You might want to add the word 'Bronze' to the Seasonic S12 II, M12 II series. Actually seasonic has a lot of series of PSUs starting with S12/M12. U might also want to write them on separate lines if a user uses Ctrl+F to search for S12 II in this big list.

I can understand that u people are not interested in Corsair VS series because it is not available in your markets. Good for you.

There are 2 versions of the Corsair VS450
1) VS450 (CP-9020009) that uses JunFu and Fuhjyyu capacitors and is discontinued
2) VS450 (75-001835 / CP-9020049) that has Aishi capacitors and MOST secondary side capacitors are CapXon

The CX series uses Samxon and Teapo capacitors and maybe 1 or 2 CapXon (I'm not sure)
The CXM uses Panasonic and CapXon capacitors

The other difference i wanted to show is this:
Corsair HX750W Power Supply Review (tested at 230V)
Corsair HX750W Power Supply Review (tested at 115V)
Same PSU model, massively different efficiency readings.
The point is the people who will use Corsair VS series will use the CX series also at 230V and the CX series will have a far greater efficiency at 230V.

You certainly don't have to stick with the Eggxpert Tiers. You can make 10 tiers if u want. Hell I would make a Tier 6 just for IBall,Odyssey,VIP PSUs. Most of my countrymen asks whether this gpu will work on these PSUs

*UPDATE* Right after posting this, saw that the SSR-650RM is on sale at Newegg for $69.99 after MIR. Getting that one.

I'm currently shopping for a PSU.

This is my planned build:
http://pcpartpicker.com/user/IndustryStandard/saved/2LfJ

I'm looking at this
http://pcpartpicker.com/part/seasonic-power-supply-ss750am

or this
http://pcpartpicker.com/part/seasonic-power-supply-ssr650rm

I may SLI or CF in the future (not yet completely decided on GPU). Which PSU would you guys recommend?

*UPDATE*: I have Amazon Prime, since that affects the price slightly.
