PSU Tier List [OLD]

[finnabuildapc]

G2 in tier 1? Huh, I expected it to be like somewhat mid-tier

[0mgblood]

Theres some $20 rebates on some the RMx models on newegg so I purchased one of those so I plan on returning the g3 once it gets here.

Why? Within 1% regulation, <20mV ripple and decent transient response. What would you want to be better?

Noise I expect, it is quite noisy

Doesn't affect the electrical performance, though.

Hello. I have a Seasonic S12II-520 (which is quite old).

 

I recently bought a 1080 TI, and I decided to replace the power supply as well.

I bought a Seasonic Focus Gold 750W. I wish I read this topic before, because now I realize this it is probably a little too much and a 650W (or even probably less) would have been OK. I have only 2 x SSD and a non overlocked intel CPU. I initially choose to bump watts a little bit to make sure there would be some margin for the power supply and so it would be very silent when playing games. My CPU (HR-02 Macho with undervolted 140mm fan) and GPU are already silent.

 

I can still return the Seasonic (I just received the package).

 

Should I : 
- Keep that Seasonic power supply. It will be almost dead silent in most cases even at full load (when playing AAA games and with 1080 TI under stress).

According tom's hardware review that seasonic power supply is silent until 490W : 

https://www.tomshardware.co.uk/seasonic-ssr-750fx-focus-plus-750-gold-psu,review-34066-5.html. Then, fan becomes noisy. 

Coincidence : 490W is also approximately the number of watts what most online calculators estimate for my config (I suspect it's a little bit exaggerated).

- Get another power supply. Less watts and more silence oriented (like a corsair RM650x). I have about 100 EUR budget (a little bit more is OK).

 

Thanks in advance.

I think the extra headroom does help the fan curve, plus I don't think you'll ever pass 490w draw.  Not a waste imo, I'd keep it.  PSU quality isn't judged by watts but there's also no such thing as too much wattage in this sense.

It all depends on a person’s scenario whether a PSU is “good” or not.

 

As a dirt cheap system integrator, that isn’t completely crap and includes a set of protections, the VS is an option. If no decent DC-DC units fit in the budget.

I was told to avoid group regulated units what do you think.

 

Anyway I don't see them being cheaper than something like a corsair CX this days, so I guess it's not worth the money.

 

system integrators are irrelevant to me, I wanted to know how good option it is for a person that wants to build his/her own pc

Interesting... Possible issues with the Seasonic Focus Plus PSUs.

These issues have been known for months.

They also released an article on HardWare Info a while back but shortly after took it down.

 

Only yesterday did Seasonic talk about it on their website

Hi guys, it's me again, wanting to ask you guys once again about PSU, so im gonna change my GPU to vega64 since I found it to be cheaper agains RTX 2070.

Problem is that, I've already bought a Seasonic FP Platinum 550w 10days(since I was thinking of getting a RTX 2070).

 

CPU - Ryzen 5 2600

GPU - Sapphire Nitro+ Vega64

MB - MSI B450 Pro Carbon AC

Storage - Samsung 860 Evo 500GB + Toshiba x300 4TB (probably gonna add more HDD and SSD in the future)

RAM - Patriot Viper 4 3200Mhz 2x8GB

CPU Cooler - Noctua NH D15 AM4

Case Fans - 7

PSU - Seasonic FP Platinum 550W (R1805 SN, made May 2018?)

Soooo, I just read that there are problems with my current choice of PSU and Vega64.

But it is written that it only affects Seasonic Focus Plus that are produced before 01.2018?
 

In case I need to change my PSU, will 550w suffice for my PC specs? Or do I need bigger PSU for the Vega64?

 

Thank you guys so much in advance!

I think you'll still be fine with a 550w, IMO. The Vega 64 is a 295w chip but from what I understand and have heard about them is you can undervolt them to reduce the power draw and heat output but without loosing any performance.

Yeah and not just the Seasonic Focus Plus.

But the worst thing is that they forgot to mention one of the main perpetrators that has Problems with many PSU on the Market: MSI 1080ti

That's one of the Worst Cards and nobody should buy it....

If it doesn't work, RMA the PSU.

Easy as that.

A Corsair AX1000? Couldn't find any references to it on Corsair's website, or by doing a Google search. Cybenetics has testing. The OEM is apparently Seasonic. Interestingly the fan RPM and noise numbers are missing? Also, sample #2 has an oddly low PF? 

For efficiency, they hit 80+ platinum. They're just shy of Titanium, only failing by ~0,5% at 50% load. At the other loads, it clears Titanium. 

In the 80+ testing, it cleared Titanium, and that's what it's officially rated for. 

The fan grille looks like the one on EVGA/Super Flower PSUs. Mixed feelings about that.

Other Corsair PSUs found on the 80+ page are the SF500 and SF400, rated for 600W and 450W respectively. Tested in February of 2017. Guessing those were for the Corsair prebuilt? Edit while I'm writing: from a Google search, that's exactly what those were for...

https://clearesult5.sharepoint.com/:b:/s/PLS/EegCY5VgCj1Av7OSC-f6looBkq_2OLbzJ1dcVB0A5XjT2A

 

Then a new AX850. Not the Gold rated one, this one is new and looks like the AX1000 from the outside, and is rated Titanium. Same thing with search results as with the AX1000. 

Was about time for the AX series to get updated. 

https://clearesult5.sharepoint.com/:b:/s/PLS/EZB0tDPGiAJFiaMM00VI7zQB7jrFw-yWneQA51E6pyYZJA?e=xBl0jc

 

And finally, an SF750. Platinum rated. Silverstone has an 800W PSU, but that one is SFX-L, so it's larger. That means this one has a 23% higher power density than the Silverstone unit. Don't know why someone would want a 750W SFX unit, but there's probably someone.

It worry me a lot as I have a Focus Plus and a MSI 1080 TI (I do not install them yet as I just received the packages).

Does this affect prime units as well ?

Can I ask you why ? AFAIK the MSI 1080 TI card has a very effective (and silent) cooling system especially the trio one.

Probably.

It affects many units that have decent OCP on Secondary side...

brutal transients, that trips the OCP On many PSU. 

I know the Bitfenix Whisper M is affected by that GPU, ev others as well

[Tigrou]

I searched a little bit and It seems a lot of people had issues with that 1080 TI card (even with PSU other than seasonic) because using 1 PCIe cable with 2x 6pin instead of 2 PCIe cables.

No, because of the Transients of the card...

I need help on deciding on which PSU to buy. I'll be using it to power a ryzen 2200g, so I don't need anything too extra, but I do want it to be silent, have good protection and not die on me in a year. My budget is around 50€ so I was looking at the be quiet 400w pure power 10 or the enermax 500w revobron. I'm leaning toward the psu being mounted vertical since I'll be making my own case, if that's a contributing factor.

John has talked about this on this site before (Though not this thread, I called out him when he said Bulldogs have 600W PSUs on the high end, when Corsair's site only said 500W on their higher end models). They are identical to the SF450 and SF600, and are only used in the Bulldog series. The difference wattages are just because they were rated at a different temperature tolerance.

Get the Pure Power, that one should be better than the Enermax and also have quieter fan stuff.

This is a Tier 4 boy, correct? Ok to use with an overclocked 1080?

It's more similar to the Tier 3 CXM. 

Should be fine.
