[EOL] PSU Tier List rev. 14.8

[LogicWeasel]

A newer Rosewill model that still seems to lack in-depth review is the LEPTON series (notably I think the only Rosewill not ranked in the list now).  That said, I'm curious where it might fall tier-wise based on the limited info we do have (discussion on jGuru forums note that it's the Andyson GX platform by all details they can see):  http://www.jonnyguru.com/forums/showthread.php?16219-Rosewill-LEPTON-Gold-on-sale-Any-good

 

Link to the PSU I'm talking about:  

https://pcpartpicker.com/product/Pvx2FT/rosewill-lepton-500-w-80-gold-certified-semi-modular-atx-power-supply-lepton-500

If it turns out to be as-hinted and the GX is a half-decent PSU, it seems like an ok competitor to the EVGA GD-series for cheaper 80+ Gold units.

Is the Thermaltake Smart M considered part of this listing for Tier D?
https://pcpartpicker.com/product/HTLypg  It might appear they just tack-on the M to mean it's semi-modular?

The Thermaltake Smart M series entry has been made, it has been decided to Tier D as well, while in some aspects the unit showed to be worthy of Tier C like still managing to be within *acceptable* numbers for voltage regulation like:

Spoiler

It has to be noted that the whole is constructed quite cheaply and just from judging the look of it you kinda doubt it would be a reliable '750W' source and this thing is really only advisable for much lower demand. This has been made clear by the proper reviews:

Quote

the supervisor IC is soldered directly to the main PCB in the secondary side area and its model number is WT7502 - Techpowerup

 

 

And then to further solidify why this is unsafe, you have an unit that is a bit more susceptible to a failure while also lacking a very important safety feature known as UVP on it's 12v rail, reserving it only to the 5v and 3.3v.

 

This is the sort of thing that increases the likelyhood of your PSU ever killing a video card for example.

 

I hope this has been clarifying, all sources used will be added on OP as well if you'd like to check them out.

Yeah that's informative and I did not suspect the unit was good, I just wanted to confirm that's what Luke meant when he just says "Smart 80+"  as that label says to me "a Thermaltake Smart that's 80+ White" .  If that label should IMPLY that it includes the "Smart M" series, then it should be added to make that more obvious.

 

The way I come across this stuff is I like to see the rank of some PSUs on PCPartPicker and when I sorted by Modular units under $100 it came up, just wanted to be sure it was ranked and didn't slip through the cracks.  I like to be able to quickly take a PSU model, and Ctrl + F on this Tier list page, to have an idea if the unit is cheap crap, or a good deal and worth recommending sometimes.

yeah, it wasn't really, hence i did a quick dive with luna, found the protection ic and saw it didn't have 12v uvp

 

hence this will now be it's placement

Oh ok, so I did find a unit that wasn't placed yet, that's neat.  Thanks to both of you for the quick turnaround on that.  The tier list is now more complete, with another unit added to the "do not buy" list haha.

GOOD PSU can be only a unit ranked B+ and above, B ones are also decent, if you are on a tight budget get lower capacity SSD or something, don't cheap out on PSU and get your motherboards VRM section and graphics card ruined by high ripple, I'm running Pure Power 11 400W on RX570, right now this PSU in my country costs 50% of RX570 price, you must know what to cheap on and what not when building a PC

Just remember that the list is somewhat based off of opinion, in theory a PSU can meet a higher tier can also be a piece of junk as they can do good in testing when they are new but, one year later the manufacture can change a few things to save money and sacrifice the quality of certain parts, so the product may still have the same part#, features and looks but may not last as long or develop problems over time.

I can now say, in my opinion  the Evga W1 PSUs are a GOOD PSU for the PRICE if you are on a tight budget.

For maybe 30$ yeah, kinda. For 45$ you could get Corsair CX (with -20$ rebate but still).

The evga 430 W1 is $25, the 500 W1 is $40-45 and the 600 W1 is $55-60. If you find a better deal on something better because of a sale or rebate then go for that.

and we thank you for making me aware of another confusingly named unit

Yes, I live in france. What's the difference between RMx & RM - RM is from 2019?

simply said

rmx is with higher end components and imo better built

rm is slightly downgraded, but meets atx 2.52 ultra low loads

i personally wouldn't even consider buying a unit without full uvp today...

[OnionFromOrion]

Where would the Enhance 7660B fit in this? It seems to be recommended for flex PSU SFF builds. It has OPP, OVP, OCP, OTP, UVP, SCP, no load protection, active PFC, 80plus plat according to: http://www.enhance.com.tw/new/enp7600-platinum-400w-600w/

Pretty much personal preference, just like how I prefer using a CRT monitor for modern PC games.

Don't have one myself, but they can be imported from taobao in China. Also a few sellers on Ebay.

No.  Whether or not a PSU is more safe is not the same as a "personal preference" that is a thing that is objectively just better.  This is like saying wearing a seatbelt in a car is a personal preference, just like how a driver prefers using a stick-shift.  Except that when you're in a crash one "personal preference" makes a pretty big difference and one makes no difference.

 

Using a PSU with less protections increases the risk to the rest of your computer.  Making a choice to use an older monitor is not the same thing.  You're drawing false equivalence.  But you appear to be giving in to some self-bias to convince yourself it doesn't matter that you cheaped out on a power supply.

Or like i prefer to not repair my car brakes, it runs fine without them.

No. Maybe you took that out of context, the risk of the piece of junk I defended is nothing to worry about when shopping at price point of 20-30 dollars, when the difference is good - slightly better, it comes down to what the shopper wants to spend in relation to quality, I prefer to be a little cheap so, I am ok with OK. If I were to be buying a PSU for a more high end system then I would buy a higher quality PSU with less of risk to damage the components I paid high dollar for. 

 

If a PSU did not have OVP, UVP, OCP and SCP features then of course I would not buy it.

the problem is that w1 doesn't have uvp...

 

hence i don't recommend it myself, even at 30 bucks

That wouldnt be about opinion tho would it?

 

And there has been cases of changes. When noticed, changes are applied to the list. Sadly we dont have a crystal ball to predict this stuff.

hm... looking into a disassembly i found the protection ic... this might get interesting

 

I'll let you know when we talked internally

i still can't decide

at that point you're not even considering quality anymore, as all 3 are honestly very close to each other, even if internally different

 

look at some reviews regarding quietness (i recall SP11 being best, but didn't check), get the cheapest out of the 3

 

or heck, look what design you like most, there is not much to be lost here

Just wanted to clarify; the list is based on opinions, based on facts. Where the opinions come into play is deciding on which facts are most important in regards to the end user (performance, design, build & component quality, and safety protections).

 

It's not based on "arbitrary" opinion.

Yeah, kinda. I may have not said what I was trying to say, my B.
