I newly built my PC as the following components:
CPU: Amd 3600X
[<font]CPU Cooler: Cooler Master ML240P Mirage[<font]
[<font]Motherboard: ASUS ROG Strix B550I Gaming
[<font]RAM: Crucial Ballistix Elite 32GB
[<font]SSD: Seagate Firecuda 520 1TB
[<font]GPU: EVGA 3070 FTW3
[<font]Case: Cooler Master NR200P Black
[<font]PSU: Cooler Master V65 SFX
But only after 1 month, the GPU was down. I asked for an RMA and EVGA sent me a new one. It worked well for another month, then the PSU was broken. Then I replaced it with a new PSU, only one week the new PSU also down. Now I'm suspecting is there any possibility that this EVGA 3070 ftw3 needs a higher wattage power supply?
Also, I only used one PCIE cable with 2 8pin connectors, someone says should use 2 PCIE cables, is that reasonable? Did anyone meet the same problem as me?

yes you should get a higher wattage power supply and yes use two pcie cables.I use a EVGA 850 GQ with my 3070 ftw3.

But it says a minimum of 650w is enough for 3070 FTW3 according to the specification.

It is, but you might experience sudden shut downs. The 30 series has a problem where there are drawing a lot of power.

never go by the minimum for graphics cards because each power supply is different when it comes to things like the 12 volt rail. Its worth the extra cost to upgrade it now just in case you decide you want upgrade the card down the road.

You'll be absolutely fine with a 650W power supply. The 3070 doesn't draw nearly as much power as a 3080/3090. The exception would be if you are running a 11900K with a full custom liquid cooling loop or something along those lines.

It depends on how good the PSU is as well. I upgraded to a 3080 without thinking really because I got it on release for msrp. I installed it in a system with a 620w seasonic psu. It worked fine and didn't shut down once under load. Obviously I didn't feel comfortable with that so I swapped it out to an 850w Gold rated seasonic.

A 620W Seasonic would be fine. People used to run SLI on 750W power supplies back in the day. You don't need an 850W PSU for a single card system anymore unless it's a 3080/3090.

IIRC Coolermaster PSU's are kinda rubbish and you're putting some fairly powerful hardware in a pretty small SFF case with limited cooling potential, lots of solid panels and a SFF psu. Does every fan position on the case have a fan? Are you maxing out the power limit on the FTW3? What are your GPU (core, mem, hotspot), CPU, System and ambient temps like? I bet that card hits 80C+ and the PSU is running hot. I'll say it right now - ITX/SFF is stupid.

I just didn't feel comfortable running it with everything OC'd as much as possible. I originally switched to a 750w ti from seasonic but that psu died very shortly after I installed it, switched back to the 620w bronze and it worked just fine, really glad it didn't take my system out with it. Picked up an 850w gold seasonic from my local microcenter and have been running smooth since.

650 is the minimum and it would be good for stability to get a higher watt one

I'd get a 750W to be safe. Anything under 750W just limits your ability to upgrade in the future.

Glad to see everyone is ignoring that OP has a SFF PSU. I'm sure that can't possibly make a difference and all PSU's are created equal.

It is, but you might experience sudden shut downs. The 30 series has a problem where there are drawing a lot of power.
Is this true of all the 30 series? Would a 650w be okay for a 3060ti?

650w is fine for 3070 and below the only way a 650w might not be enough is if you have a ton of other stuff in the pc

Nobody read OP's post about using one cable from his PSU to power his GPU? 650 should be plenty but you'll need 2 sepperate cables to power your PSU buddy. That would be the problem here

Why would the PSU cables come with 2 ends if it wasn't made to be used on both slots?

people seem to be quick to forget nvidia's reccomended power supplys are based on a 10900k system and im sure they are taking into account the 200watts for the cpu that it can pull under max load. so if you don't have a monster cpu. you would be just fine with a 650 for a 3070 build. the 30 series gpus do have random peaks so having some extra head room is nice. if the op was on a 10900k overclocked system and wanted to move the power limit on his 3070 then id say 100% move to a 750. his pc killing a 3070 and two psu's it may be more down to either the quaility of the psus or quaility of his power its hard to know for sure but it seems pretty odd to kill a 3070 and two psu's in a short time like this but its not impossible to just be that unlucky

PSU efficiency peaks around 40%-60% load. So if you're conscious of your energy bill, getting a slightly larger PSU would be better

650 is perfectly fine.
+1 I got a complex custom loop (two pumps) + OC'd 5930K + 2080 Ti, 6 mechanical drives, 2 M.2 SSDs and I usually pull around 500w-600w on load, gaming, folding, etc. I might pull more say if I'm running some benchmarks like furmark and such other than that, 650w is fine for a average system.

I’ve read that you realistically need at least a 750W for smooth performance

Sure but a 650 will be fine
