PSU tier list 2.0

[Archaic59]

The RM750 is in tier3 because it did not do as well in tests as the RM850.

Has HP ever used Seasonic or similar great OEM for thier PSU's?
I put full load on everything with benchmarks and I still have legs...

My friend got a EVGA 600W... Closest review I could find was the 430W and 750W on JonnyGuru... But one got a 5.5 and the other a 8.5(respectively)... Should he return it ASAP. with a Q6600 and a 7950? I'd think it would be fine, what do you guys think.

The NEX650G has a quad 12 volt rail system... Max I've seen is first... very interesting

[Turb0Yoda]

Crap, I read that one a long time ago and it didn't come to me yesterday..

He should be fine with a 960 though, right? It was 40 bucks on sale which was why he got it. I alerted him to the fact....

Math is easy. You buy a cheap psu for $40 that lasts Mebe 3 yrs, buy another cheap psu for $40 that lasts another 3 yrs, then another which lasts for 3 yrs. In 9 years you buy 3x $40 psus and need to buy a 4th, so sum total for a working system 9 years from now is at least $160 before taxes. OR buy 1x evga/Seasonic with 10 year warranty for $100 after taxes. 19+ years from now you will have spent only $100 for the original psu, vrs the $320+taxes for psu's to cover the same time period, and the quality of output performance between the psus is vastly different.

A $40 psu is only worth about as much as the cardboard box it comes packaged in.

 

[Darkbreeze]

Depending on the requirements of the system of course. If you're running a low powered AMD APU or G series Pentium that's not overclocked with no discreet card and one or two memory modules, a 40 Antec VP-450 or Seasonic SS may be running well for years and years. Add a low end discreet card and a year later it might be done.

It is simply a bad unit. It is basically a re-labeled FSP Raider.

Here you can see the review for the Raider. http://www.hardocp.com/article/2013/01/03/fsp_raider_750w_power_supply_review/9#.VeTWAMMYqUl

Although I couldn't find any reviews for the NEX 750B, I was able to find some for the NEX 750G also manufactured by FSP and degraded to tier4. Compared to the Raider 750W, this unit seems to have better capacitors and performance results.

and

http://www.techpowerup.com/reviews/EVGA/NEX750G/4.html

Are you sure that they are the same as the Raider 750?

B and G units are entirely different. B1 and B2, and G1 and G2 are also entirely different. Different platforms and you can't use the reviews on one for the other.

If they are so different, then why was the 750G down graded to tier 4 along with the 750B?

 

[Darkbreeze]

Because they're both lower quality than the B2 and G2 units. B2 and G2 are both Super Flower built units. B1 and G1 NEX units are manufactured by HEC and FSP I believe.

 

[Onus]

I think his issue is a valid one, but his method of expression was somewhat rude. NO "tier" list, NONE, reasonably covers all units, for a variety of reasons. Testing methods and environments differ, individual samples differ, and the opinion of the tester differs (e.g. what weight to apply to various factors). It also doesn't answer the "real" questions, which are:
Q1. How many watts (or perhaps more appropriately, "how many +12V amps") do I need?
A1. I use http://outervision.com/power-supply-calculator myself. There are others, but most are based on this.
Q2. Ok, needing "n" Amps, and with a budget of "$x," which unit should I buy?
A2. If the answer is not "You need to raise your budget" (i.e. there is in fact an acceptable-quality unit), then a list of 2-4 PSUs to consider may be a more useful solution than a large tier listing.
I like the listings at JonnyLucky.org. Rather than try to come up with arbitrary tiers, it basically offers what is essentially pass/fail advice.

Thanks for this list. It is really helpful. I don't see Kentek PSU's on here. Are they not an good?

 

[Onus]

Kentek sounds like a generic. It won't be any higher than tier-4, but personally I'd be safe and consider it a tier-5 leper outcast unclean.

 

[Dark Lord of Tech]

Right on Onus , they are easily a 5.

Thanks for the help. I probably wouldn't have bought one anyway, but I wanted to be sure.

 

[Benjiwenji]

Because they're both lower quality than the B2 and G2 units. B2 and G2 are both Super Flower built units. B1 and G1 NEX units are manufactured by HEC and FSP I believe.

I knew that the B2 and G2 are by superflower, but both the B and G are manufactured by FSP according to realhardtechx. That's why I didn't think that the G, which has decent reviews, would be far off from B.

 

[Karadjgne]

B is Bronze efficiency, G is Gold efficiency. Neither has anything to do with quality of build or quality of performance. There's quite a few bronze units I'd be quite happy owning, and just as many gold units you couldn't pay me to take for free.

cough cough Raidmax cough cough

 

[Darkbreeze]

That's not accurate. These are from both RealHardtechX and Tom's hardware's "Who's who in power supplies", and both reflect the same thing, which is that they are FSP and HEC.

 

[Daffa Romero]

Hi, would like to ask.
1. Is the Enermax NAXN 82+ 550W ETL550AWT good? What tier does it fit in?
2. Will the Seasonic S12-II-520 be a better pick?
3. Will any of the PSU's above will be enough to power i5-4590 + Palit GTX 970 Jetstream?

Thanks in advance.

 

[RCFProd]

The Seasonic S12II 520w is a good choice for i5-4590 + GTX 970.

The Enermax is not. Avoid all of the Enermax power supplies if you can. The Enermax power supplies that are actually good are very expensive.

 

[Daffa Romero]

To RCFProd
Interesting. Okay, would try to invest on the Seasonic. Wait, is 520W really ENOUGH for that? Weird.
Thanks a lot anyway.

 

[RCFProd]

Technically you would already be fine with a 450 watts power supply. With the 520 watts you have a bit of head room, which is better for your power supply as it won't have to work under full load (stress) all the time meaning longer durability of the PSU is more likely.

Really? Great.
Was looking on investing in one, but I am afraid that it won't be enough.
Great answer. Thanks a lot man.

 

[stavrosmast]

my corsair vs650 is very expensive in my country.. wow and i thought i had agood psu

 

[GObonzo]

have seen a few of these for good price but reviews i find are totally mixed from high ratings with awesome performance and build quality to them being false advertised garbage.
still listed in the Tom's PSU tiers as: un-tiered gold. wondering if Tom's has any new info or links to reviews\articles pertaining to them.

RAIDMAX Vampire Series RX-800GH

 

[tiny voices]

They are not as bad as the rest of the Raidmax units, but they are certainly not good or worth buying.

They have more than 520 watt units. And they have more than 80+ Bronze.
