The Power Supply Unit tier list Discussion thread

[ko888]

I saw someone list a Thermaltake SP-850M in a build they just recently completed, and I'm having some difficulty with figuring out where it stacks up. According to HardOCP, it passes their testing; however, I don't know if that's enough to rank it. Dottorrent did say in an older thread (2013) that the SP-850M was made by Sirtec, and it should be "fine." I'm wondering where it would rank, if it ranks on here at all.

The Thermaltake SP850M is not made by Sirtec. The UL file number on its label is E161451 - Channel Well Technology Co Ltd. Even the teardown shows the typical CWT characteristics (i.e. dark green colored tape on the transformer with the CWT name and part number stamped on it).

[H]ard|OCP's review stated that the ripple level is on the high side and so ranks at the rear when compared to its competing brands (e.g. NZXT HALE82 850W and Corsair TX850 v2).

I'm sure it was made by Sirtec, maybe the older models. I'm sure I found a review last year stating it was made by Sirtec.

Only the SP-1000M and SP-1200M models are made by Sirtec/High Power.

Well, the Thermaltake Smart series units are currently rated in tier 4. I take it that wouldn't be a decent OC'ing PSU? If so, I might want to track down the OP of that thread... he was thinking about OC'ing.

What are your specs and what's your budget?

Newegg has the Seasonic G series 750w model on sale for $65 after rebate and promo code until 10/24. Great unit and plenty of power for any single and even some dual GPU setups. Almost impossible to beat the quality and wattage for the price.

I'm talking about another thread, where the OP already put in the Thermaltake 850M. This won't be for my own build. My build will either be using an Antec HCG, or a Seasonic S12II.

Both based on an older less efficient Seasonic platform than the G series. Well 2 of the higher wattage HCG models are made by Delta but still an older less efficient design.

I just thought from your posts you were looking for a good, cheap power supply and the G meets that criteria.

Hello everyone,

I'd like to clear my doubts about EVGA 500B, I see it in Tier 3. But, this unit made by HEC got a fairly good JG review with 8.7 rating.
http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story6&reid=351

Shouldn't it be in Tier 2? I'm sorry if this has been asked earlier on this thread, I couldn't find it.

 

[Deleted member 217926]

Nope. Tier 3 is correct. As said in the article it's average in every way with fairly high 12v ripple, Capxon and Teapo capacitors and some soldering issues. There are much better units for a similar price.

Tier 2 is for very good units and tier 1 is for the best of the best.

 

[MeteorsRaining]

Noted. The main concern is, the list puts it alongside Corsair CX and VS PSUs, which I've seen is preferred by people many a times over this particular model (500B). Now CX and VS are poor quality, and not as reliable as 500B, then is there a way to arrange them lower (or 500B higher) in the list?

 

[Deleted member 217926]

Actually the CX is probably close to equal or even a bit better than the 500B. The VS is only available in parts of the world that use 220VAC so it's not as reviewed but it's similar in quality to the CX. Nothing wrong with using any of those units as long as they are used as what they are, budget power supplies. Don't run high power GPUs on them and don't overclock with them. Also expect them to last about as long as their warranty.

 

[MeteorsRaining]

I see. Thanks for the help

Seems pretty crappy.

Indeed, VP450 or 550P made by Delta seems like a better option.

Hello,
Just wondering, why is the Fractal Design Integra R2 750watts PSU in Tier 3 while this Hardware Secrets review gave it a Gold award?
Link:http://www.hardwaresecrets.com/article/Fractal-Design-Integra-R2-750-W-Power-Supply-Review/1688/13
Also, is the SuperNOVA NEX 750 watts in Tier 3 the G1 or the B1 unit?
Thanks.

 

[tiny voices]

Both the G1 and B1 units are tier 3. Only the G2, P2, B2 units from eVGA are worth buying.

 

[zeyuanfu]

Oh, okay. That clears up half of the things I've been wondering. Still don't know why the Integra R2 is a Tier 3 unit, though.

 

[tiny voices]

Probably due to:

poor 3.3V rail performance on Advanced Transient Response tests
Loud fan
Only six sata plugs and TWO Molex plugs on the whole unit.

They either got a cherry picked sample or HEC has major quality control issues. Kitguru gives it a 7/10 due to the fan breaking in the box, being cheaply made, noise under load and Teapo caps.

http://www.kitguru.net/components/power-supplies/zardon/fractal-design-integra-r2-750w-review/7/

Techpowerup gave it an 8/10 saying the design should be limited to 600-650w max and as such has loose regulation. They also found it noisy and poorly made.

Tier 3 sounds about right to me.

 

[zeyuanfu]

Would any of these two PSU be good?
https://pcpartpicker.com/part/ocz-power-supply-oczzt650w
https://pcpartpicker.com/part/thermaltake-power-supply-pstpd0650mpcgus1

The first choice is untiered and I'm not sure about the second unit...

 

[tiny voices]

Not a big fan of thermaltake. They made SOME good units but mostly junk.

I have seen mixed reviews on the OCZ unit. Based on what I have seen I would call it at the top of tier 3. MAYBE tier 2b.

 

[zeyuanfu]

Yeah, some people on Amazon say it's great and others say it's loud.

OCZ PSUs are now under the Firepower Technologies brand. The ZT units are in Tier 2 Class B.

OK, thanks!

Where would Rosewill 630w Green series rank? Is this a decent psu for budget builds?
