Should this be enough? (1000W PSU Rosewill Capstone)

[sepheronx]

Ok. I'll wait for shipment and refuse it.

Any recommendations on a PSU?

Lot's of good, better, and excellent units out there (although a bit pricey now a days). I'm not positive of your budget or your PC case but two RTX 3070 running 24/7 in mining (I believe that is what you said); it's going to get hot in your case so looking at PSU rated to 40c would be my starting point with an eye on 50c rated units as a better option.

I'm putting it in another rig that will be open air.

Ordering some PCIe risers as well.

that will help, I looked at Amazon & Newegg ca, the inventory and prices of 1000w sucks. For around $170 CA I saw 850w units for the seasonic focus, corsair RMx & tx-m. All those units offer just as much real world power as that Andyson unit (if not more) and are designed to run 24/7 at load.

If budget is a concern I would go corsair TX-M, 50c rated, 7 year warranty

Will this be enough for 2 - 3 RTX 3070?

I'll have to wait now for a while before I buy because the refund.... If I refuse order and it gets lost in the mail, I'm hopped apparently. Item is at Purolator so we will see. May be another month of so till I get the necessary parts so one rtx3070 is sitting idle (I got 3).

like I said I''m not sure of your budget but I would definitely start my search with that unit. The TX850M is well reviewed, well built, and on sale at this time. If you are going to wait you can then look at the seasonic focus 850w as well (although some people have said they had issues with the RTX3080 & 3090 and 750w version of that unit). The focus is also a 50c rated 7 year warranty unit that is slightly better than the TX-M but wasn't on sale. Personally, if I had more money I would go with the corsair RMx850w. I have nothing against using a 1000w unit but you would need to pay almost $100 CA more to get one of similar quality when I looked at your market and a 850w unit will do the job (see below).

review on the 750w version

Corsair TX 750M Power Supply Review (80 Plus Gold) - KitGuru

Today we test a Corsair power supply from their new TX-M series comprising a semi modular design, ti

www.kitguru.net

guru 3d has the RTX 3070 pulling in just over 200w with the following recommendations
Here is our power supply recommendation:

• GeForce RTX 3070 - On your average system we recommend a 550 Watt power supply unit.
• GeForce RTX 3080 - On your average system we recommend a 650 Watt power supply unit.
• GeForce RTX 3090 - On your average system we recommend a 750 Watt power supply unit.

using a power supply calculator, it spit out the following using your set up and a full 24/7 load (I guessed on CPU cooling and went heavy on it just in case)

Load Wattage: 629 W
Recommended UPS rating: 1200 VA
Recommended PSU Wattage: 679 W

I would have no personal issue running that kind of load wattage in the PSUs I stated above.

Thanks man!

Currently, I have a 750W CM Gold PSU (MWE model). It seems to be working fine. My question is, should it just be sufficient to use that for the two GPU's on the T1650 I had mentioned above in an open case? Cooler is stock cooler for CPU. I can replace the 750W I have in there with my 550W gold model of the same thing to run my ASUS Dual OC RTX 3070 as the two Gigabytes I have can be in my mining rig.

What do you think?

this is my current PSU:

Amazon.ca

Or maybe I will just by the the one you suggested seeing as how mine gets questionable reviews.

 

[phill]

Never skimp on a PSU, if you think about it being connected to all of the components in your PC and if something should happen it could take all of them out (absolute worst case) then an extra $50 to $100 on something decent is more than decent to handle $1000+ worth of kit (for the sake of argument.)

I'd suggest anything top tier and only top tier. Seasonic, Leadex/Super Flower, possibly EVGA but the P range I think as I believe their G+/G5 range is not Leadex OEM. They are about the only ones I'd trust and use. 850w to 1000w would be more than fine for the two cards. I'm running 2 1080 TI's with a Ryzen 1700X on an 850w, loaded (with the cards tweaked) I'm pulling from the wall under 500w. Just to give you some idea.
I see that you mention mining, so you'll be undervolting them anyways

 

[Solid State Soul ( SSS )]

Yes two 3070 equals 500w TDP so it should be good

this is my current PSU:

I believe there are two versions, the second version should state "V2" on it. The biggest difference is the first version only has two PCI-E modular ports on the PSU itself that each split into two connectors to create four total connectors (if I recall correctly). I would not use that first version as you can go past ATX spec load on the pci-e cables. The second version goes with four ports on the PSU, if you have the second version and plan to undervolt you should be ok plus you already own the unit. I'm not crazy over the part selections of MWE line but Cybenetics has tested multiple MWE units including bronze, V1 gold & V2 gold and Aris has stated he never had an issue with them.

I think it's the two ports. And honestly, I ran the RTX 3070, 1080ti etc for while with no issues with just the 1 cable that splits to two. But I get what you are saying, may be a problem.

what about this PSU?

the old RM was 40c rated ("RM" is yellow on the PSU sticker) and came with a five (maybe seven year warranty, can't recall) and was a step below the TX-M. That's the new RM series in your link (PSU sticker is all white), it is 50c rated with a ten year warranty making it a step above the TX-M series (basically replacing it) while a step below the RMx series. I would have no issues using it as it's a very good PSU with a refined platform by Corsair/CWT.

So I ran the two GPU's no problem. But I did it for a test and well, while it worked great, first GPU was heating up real quick (lack of air). So I gotta order that open air case now.

First GPU shot up from 52C to 73C and counting and that was with fan speeds at 70%. So at that point, once it hit 74C I shut off the machine, took the second GPU out and then let it run as normal. Till then, I can live with 1 RTX 3070 in 1 machine and 1 in the other for mining.

BTW, I recommend the Gigabyte model over the Dual OC from Asus. If anyone is wondering.

You can use a fox 3 blower to force air between the cards (works doubly to cool the back of the lower card and feed air to the top card). Fox 2 is also a good option but is more difficult to mount and takes up more room.

I want to start off by asking if this PSU will be sufficient to run 2 Gigabyte RTX 3070's?

Rest of the build:

Xeon E3-1270 V2
16GB DDR3 1600 RAM
500GB SSD
2X Gigabyte Gaming OC RTX 3070

Maybe my choice would be different.... taking only 1 RTX3070 and using the rest of money to upgrade to a more recent set up with a new motherboard, new cpu and new ram... so with a 600/650W you'll have enough to power it. If you continue in your way you'll certainly have some bottleneck somewhere.

I think you need to re-read the thread. This is for mining. I have a 3070 separate of the two for gaming and mining in my main rig (10500es setup).

I know I didn't make it clear in initial post.

 

[sepheronx]

My wife says to keep it, but I may just return it. The PSU did come in and I still have it in its shipping box. I guess I gotta go to Purolator and have them return it. She says why not keep it, take it apart, take pictures, and have someone stress test it to see how well it works. And then keep it for a build to sell in the future or for expanding the mining or whatever.

I ended up ordering this:

So I will just use my spare 550W to run the system and 1 GPU while the other GPU's will end up using this server PSU and the breakout board.
