PSU tier list 2.0

[tiny voices]

I would say tier 2 yes.

 

[logainofhades]

Then I will probably recommend them, when they are priced right. I often recommend the B2 750, but if the GQ is cheaper, then probably will choose it.

 

[tiny voices]

I recommend the B2 alot. GREAT unit for the price. I doubt the GQ will be cheaper than the B2.

B2 is same price as the GQ750 watts. The 650 watts is 10 dollars cheaper and the recommended option for single GPU setups over the 80 dollar B2 750w imo.

 

[tiny voices]

I recommend them both, although I'm not a big EVGA fan personally.

I read over almost every EVGA review on Jonnyguru today. The GQ series is definitely a Tier 1 or 2. What we're forgetting here is that we shouldn't judge a whole series of PSUs and stick them all in one tier. All the different wattages have varying quality. The 1000W GQ is, pardon my French, better than the 1000W G2. The 1000W G2 uses non-Japanese polymers in the secondary, and while maybe Jonnyguru doesn't seem to care for capacitors anymore these days, the GQ uses 100% Chemi-Con, even the polymers, and voltage regulation and ripple are fantastic, even without the inline capacitors in the cables (at least I don't think they're present).

Same with the GS series. For some reason, the 650W GS uses some non-Japanese capacitors, too, whereas the other-wattage models use 100% Japanese. That's why we should be talking about exact wattage models of a series, not the series in general.

Look at turkey, gettin' all PSU with it. I remember not that long ago you were asking incredibly basic questions, now you're questioning the entire process of selection. Yes, you're right, many models need to be individually considered as there are clear differences between models even in the same line, regardless of what line we're talking about.

 

[Karadjgne]

Have to be careful of labels. Just because a cap, be it polymer or electrolytic is not Japanese, doesn't necessarily mean that it's junk. There are several manufacturers in the US and Europe who make caps of excellent quality too. While not as prevalent as Japanese or Taiwanese or Chinese caps, there are some used nonetheless.

 

[turkey3_scratch]

I always look up the capcitors when I find them. The ones used in the 1000W G2 are Capxon.

I've seen Korean, too.

Johnny's scoring system is all screwed up. When looking at his reviews, avoid the scores, and just read what is important.

truth.

I am a fan of their B2 and G2/GS units. I was thinking they are probably a bit better than G1, but still not as good as G2/GS. The 650w GQ is going for about $70 right now. For those wanting modular, but don't need a 750w, the GQ could be a good buy.

the 650/750 GQ have similar performance to the 550/650 GS, though the load regulation is much better than the 550/650 GS. like the GS units, the 850 and 1000 watt models are a better platform than the lower capacity models.

Thermaltake TR2 600

What tier is this? If un-tiered, what is the quality in your opinions?

User states: "pcpartpicker said this psu was fine".

 

[Onus]

Assuming an older one (with a little voltage switch), tier-4 at best.

 

[Deleted member 217926]

Depends on the exact model. Anywhere from terrible with the older ones to middling quality with newer models.

 

[rcald2000]

user: "i bought it a couple months ago so its pretty new has never had any heavy loads on it until i installed this gpu "

 

[turkey3_scratch]

Johnny does score some stupid stuff. For instance, berg floppy cables. Why does that deserve a scoring deduction? What harm is it realistically doing? That one I think is outlandish. They also score off if a modular cable can be plugged into where it shouldn't, which some may argue is a good thing, but realistically speaking, how hard is it to read the labels?

Anyway, I usually read through the reviews and ignore the final scoring page. They have great information. The only parts that trip me up are in the dissasembly, when he's like, "This part is an SF32JlK7 diode"... Okay? I know what a diode is, but they just say what the part model is without saying if that's a good thing or bad thing (because come on, 99.9% of people reading the dissasembly probably glance over those model numbers). I'm guessing it's all just fine, they just want to be specific about whats's on the inside.

 

[logainofhades]

He deducts for a unit being semi modular, vs full modular. That is just stupid.

 

[turkey3_scratch]

I found the quote from him I was looking for.

High reliability Japanese capacitors? You know, after my long rant from that Corsair review last week (Rm 850), I am starting to think differently about capacitor quality. You could say my eyes have been opened to a stark realization... the bad old days of capacitors dropping dead left and right are mostly over, except for the "off the back of a white van," brands that are as awful as ever. No longer are the Japanese parts the only good parts in the universe, and they're now often made near the Chinese parts we've been bashing left and right since capacitorgate was a thing fifteen years ago.

I don't know though. We all see how often those CX units fail, constantly I see it. I see tons of power supply failures daily, probably all due to dead capacitors.

And when I refer to "Johnny" I mean OklahomaWolf usually since he does all the reviews, not Johnny himself.

 

[Darkbreeze]

Pppffftt. If I worked for a company that used chinese capacitors in all it's products, I'd say that too. Can't blame him really. No matter how well his intentions may be, it's impossible to juggle working for a major brand and honestly seeing things from an impartial point of view. He never made comments to the effect that chinese caps were "ok" before he worked there, and I'd bet if he left there and began working for a company with a different outlook on quality, he'd again change his stance. It's human nature.

The funny thing is, if the chinese caps are so good now, why does Corsair's high end products use mostly Japanese caps? C'mon, if it smells like the ocean, it's probably either fishy or you gotta take it with some salt.

 

[turkey3_scratch]

I agree with you Darkbreeze. Plus, all the units that are reviewed there are brand new. You don't see them running these things for years and waiting for them to blow. They test them brand new, and stick it on a shelf.

I actually just read a 5-year-old review on the OCZ 550W. It's actually a very good unit. 100% Japanese capacitors, voltage regulation around 1.75% average, ripple on the 3.3V and 5V are good, the 12V is 60mv. But still, I always considered OCZ to not be very good, but I'm trying to read every review from an unbiased standpoint.

How come we have no OCZ units on the Tier List? I think it could be added as a Tier 2. "OCZ ZS 550W". And I still think the GS 650 needs knocked down a tier.

 

[Deleted member 217926]

OCZ went bankrupt. Their power supply division is now called Firepower and they continue to make some OCZ models as well as some PC Power and Cooling models. OCZ units from 2007 and earlier were mostly to be avoided. They turned that around though and almost every unit from them newer than that was listed tier 2 or better.

Edit: I should say that Firepower bought the former OCZ power supply division. It wasn't just a spin off like I made it sound like in my post above. Toshiba bought the old OCZ SSD division.

 

[Turb0Yoda]

Wasn't capacitor gate where that secret formula was stolen that was supposedly the best one there until it was revealed it was top secret since it was defective?

 

[Darkbreeze]

No, capacitor gate is a homebrewed electric fence. :lol:

 

[Turb0Yoda]

Did that happen even... I feel like it was a joke, but my teacher worked at a couple of companies dealing with the stuffs so....

 

[Darkbreeze]

Yes, it was a joke.

Manufacturer: Thermaltake
Model Number: SP-650P

Question: Is this the tier 4 PSU listed below. The "SP" prefix has me uncertain. It's powering a GTX 970.

"Thermaltake Smart / Smart M Channel Well Technology (M Suffix, 550P, 650P, 750P) / HEC Compucase (430P, 530P, 630P, 730P) / High Power (1000M, 1200M)"
