help choosing psu

[Flawizz]

need psu experts to figure out which one of the following 3 psu's i should choose, need for 3080/3700x/16gb

[Alex Ushigome]

The cooler master since it's cheaper. Both the be quiet and Cooler Master are B Tier, can't find anything on the TX. How much does an RM650x cost?

All are excellent units. Pick whichever

[cm992]

get the fully modular one, so much nicer to build with

120€, but i dont think 650 would do for a 3080, even if it does, might use some headroom incase ryzen 4000 drops with some nice performance increases.

Dont bother if its 20 euro more. If you want to compare PSUs use this list

according to the list, both coolermaster and corsair psu are bad, the be quiet psu is b tier. il check if theres an affordable A tier tho

Q: Will my powersupply work with the new RTX 3000 Cards

• A: NVIDIA gave the recommended power supply wattage's for use with the RTX cards  when paired with the most power hungry mainstream CPU in their presentation. These are 650W for the 3070 and 750W for the 3080 and 3090. The cards themselves take 220W, 320W and 350W respectively. Depending on your CPU, motherboard and other components most systems will not go past around 200~250w so if you are above 750w you are almost guaranteed to be fine unless you run a Threadripper or Xeon system. For everything else 650W will be perfectly fine even with a 3090.

But yes, unless you're going top of the line, 650w should suffice. Won't know until reviews are out though. And the RMx series are tier A, compared to the ones you listed being tear B. That's why I suggested.

all 3 will be great, all have 100,000h estimated time between failures, all have high quality caps and chokes (most likely from the same factory), all have decent warranties, it really comes down to company preference. 
beQuiet is my choice, 2x 12v rails is a "nice to have" however unnecessary in most high end psus like these.

The coolermaster is tier B. The Corsair isn't on the list.

2x 12v rails sounds like something really good, il have a look at whatever i can get from A tier, gimme a sec

[marmour]

The BeQuiet and Corsair are both A tier I believe. The corsair one is the "TXM 2017 gold" I believe, unless the V2 is a different model

[Flawizz]

yeah i think i will go with the be quiet! Pure Power 11 700W CM psu

thanks

what is your opinion about the bequiet pure power 11?

Good choice

[MrBrightSyde]

@marmour The Pure Power 11 is Tier B with the Coolermaster MWE Gold.

 

@Flawizz The Corsair TXM would've been a better choice

 

For those blind, the TXM is Tier A

I mistook the straight power for the pure power, my bad. Its still a decent unit though.

 

I did point out the TXM anyway, and yes it is the best choice

Oh I know, should've been more clear that the only part you were wrong was that the Pure Power 11 was Tier A when it was Tier B.

oh right, but its single rail, i've heard bad stuff about single rail, the pure power 11 however has 2 rails as far as i've heard, did you take the rails into consideration when making your decision? thanks in advance!

there’s no effective difference in safety between single-rail and multi-rail PSUs. It's more of an added protection since if one rail fails, the other still works. I would only factor in multi-rail if you were doing a multi-GPU setup in any case.

I can actually make a real difference in the high wattage units....

 

Take mine as an example, HX 850... In multi rail mode it's 40 amps per rail, 7x 12V+ rails, or 480W MAX before it would shut down if something happened. In single rail mode that would be 70.8 amps or 850W that could do some real damage... Worst case....

Which is why it's a "nice to have" protection for most people. It's not a end-all-be-all when choosing a PSU.

Never said it was....

 

It's added protection and more relevant for the higher wattage units.

 

Mine has 7X 12V+ rails so it breaks things up nicely in Multi rail mode.

if the rails dont matter (as much as the tier), and the txm is A tier and the pure power 11 is b  tier, what makes txm worthy of A and pure11 not? i have no clue. thats probably gonna be my deciding factor if it is a very valid reason in tier difference. thanks in advance!

Build quality, mostly. That and Corsair has a 7 year warranty vs 5 year from Be Quiet!. Also the TXM has better performance according to Aris
