PSU tier list 2.0

[Karadjgne]

Titanium rating has been out for a minute. Probably won't be any higher without a complete change in how psus work. Components give of heat, therefore there is some resistance, which will lower efficiency. A lossless, 100% efficiency would be great, especially on the electric bill, but ain't gonna happen any time soon.

100℅ is fundamentally impossible.

You never know. They may be able to push them to 98% at best.

I still want a Uranium rated PSU. That way if there is a bad brand we can say it will go Nuclear.

 

[USAFRet]

Uranium is passe'.
Unobtanium is where it's at.

 

[turkey3_scratch]

I think diamond is the next one. If there will be.

EVGA G3 units (all of them) are on Newegg now http://www.newegg.com/Product/Product.aspx?item=N82E16817438095 surprised to still see 7 year warranty instead of 10 for the 550W and 650W ones.

 

[CTurbo]

^It's too bad they don't have a 450w version. Seriously.

 

[turkey3_scratch]

It'd probably cost $1 less than the 550W version. Corsair is going to have to compete with this, the G3 should beat the RMx as seen so far with the 1000 G3. Plus 150mm depth with that kind of performance is stunning.

 

[CTurbo]

Yes that's probably true. Pretty much the reason I rarely recommend a 450w over the 550-650w models.

I know the temp guide in my sig had some strange problems but that was months ago if not last year.

You should make a post in the Forum Feedback section and be as detailed as possible. They like screenshots. Kevin will see it tomorrow and forward the info to the devs.

Hi, So on the lookout for a new PSU, my budget was approx £100. I then noticed this deal on Amazon for a HX850i. Just wondering is it worth it? I asked else where and I was recommended to go for a 750W Seasonic G Series thats near the same price. Around that £100-£130 price point there is a lot of good PSUs, just wondering what people would recommend. I have a old i7 3830 that I will be over clocking and currency running SLI GTX770 that I hope to replace soon for a 1070/1080. Then in a few years I will upgrade the MB/CPU.

 

[superninja12]

yes get that Hxi its a great deal for the price

 

[CurnRaisin]

yes get that Hxi its a great deal for the price

Thanks for the reply. Right, so you think I should jump on that deal as its unlikely I'll get a better one, or wait till the 25th see if a better deal comes up? My PC is still up and running fine with my old PSU so I'm not stuck without or anything. But I wouldn't mind seeing if a Corsair AX model dropped in price

Edit: I fairly sure it is but 850w should be more than enough for 2x 770 sli, right?

Hey I have a question... Can a Seasonic SSR-650RM - http://www.newegg.com/Product/Product.aspx?Item=N82E16817151118&cm_re=seasonic_ssr-_-17-151-118-_-Product - Run a Sapphire R9 Fury?

 

[logainofhades]

Yea, that PSU is capable.

 

[Mac070]

Yea, that PSU is capable.

Thank you! Because my friend has a system consisting of the FX 8320 and the CX750M( The newer one) . He had me pop it in my system since it was stuttering on his. So i started up BF4 and i said : Let's max this hooker out" So i cranked everything up and the frame counter hit 19FPS and it frooze. Forcing us to CTRL - ALT- Delete out. He said it was my crappy PSU and that his CX is better than my Seasonic.

Don't want to fray away from the PSU topic. So thanks!

 

[logainofhades]

He actually said CX is better than Seasonic? :lol: Your friend doesn't understand power supplies at all. The old CX750m is a horrible PSU, in comparison. The old CX weren't great, and the old CX750m was probably the worst of the bunch. Granted your PSU is probably borderline, on needed wattage, but it is a much higher quality unit.

[Mac070]

Yes he has the newer black and grey Corsair CXM 750W. He thinks it's better because it has more wattage. I told ihm if it were my PSU then the system would have shut down or blue screen. Which it didnt. Just sounds like a normal AMD card that cant handle BF4 max out 200% res scale like my 1070 😀

 

[logainofhades]

Those are better units, than the old CXM, but I wouldn't put them on the same quality level, as a Seasonic gold rated unit.

In any freeze where you can ctrl-alt-del out of it it's always software related. A hardware freeze is permanently frozen, you ain't getting out of it.

@logainofhades: CX750M worst of the bunch? It was always a more modern design than the others with DC-DC converters. The lesser-wattage ones were group regulated. That alone makes it better.

 

[Deleted member 217926]

The CXM 750 and 850 aren't new. Same CWT PUQ-B platform with the 850 being the better of the 2 with all Japanese caps.

The CX450, 550 and 650 are the new ones and they are based on a downgraded version of the original RM platform if what I read on the jonnyguru forums is correct.

I tried to Alt-Tab out of the game but that didnt work. So i could only Ctrl-Alt-Delete out of it . Probably his graphics card. We popped it in my system due to it stuttering in his system.
