Is buying a PSU now a bad idea ?

With the 50 series out now using a upgrader12VHPWR is buying a PSU with a 12VHPWR compatible with that new cable ?
 
no, just make sure the psu and cable is supplied by a reputable manufacturer i.e seasonic

If you "need" a new PSU now, no.

If you don't need a new PSU now, yes.

It always never a bad idea to get a good power supply! By looking at your system specs, you probably don't need it though.

They are compatible, the newer 12V-2x6 connector is just a revised version of the 12VHPWR connector. The main difference being shorter sense pins and longer 12 pins, the changes are suppose to make the connection more reliable.

The Asus Thor and Thor II power supplies are made by Seasonic, think of them as "rebadged" Seasonic Prime power supplies with extra Asus added features. So if you absolutely have to use a 12V-2x6 for whatever reason, you can just get this cable from Seasonic.

There are so many others that are good.

i know but seasonic is all i could think of at that time..
corsair.. bequiet! etc
 
If you need a new PSU then personally I would just get a reputable PSU and then use the supplied 12VHPWR connector that came with the GPU if you're worried about incompatibility or outdated cable that is supplied with the PSU.
 
I just bought the Thor III from ASUS, I was using a Corsair RMx 1200w Shift.

With the Corsair I was getting 12.009-11.88 idle and 11.750 to 11.685 load 16-Pin 12VHPWR .. So 300+ droop.

With the Thor III and supplied cable I am getting 12.17-12.05 idle and 12.01 to 11.96 load at full 600w power. Around 100mv droop super stable power delivery. Although Ive always used Seasonic OEM PSUs so kind of testing my luck with this one.
 
I mean I'd aim at getting a ATX 3.1 or latest possible standard.

The 12VHPWR is called 12V-2x6 when buying a 3.1 standard PSU. You get other goodies like, low power state, etc. etc.

Notice how the 2x 8-Pin is actually wired for 6.

Who would have thought we never needed this 12V-Fire connector and could get away with just 2x 6-Pin on the GPU :rolleyes:

Using software or measuring device , I have a Seasonic Prime TX 1600 3.1 , Hwinfo64 not even close ,I use WireView and Dr.Power III , plus a clamp meter , my 4090 tested , using a measuring device, 11.9V at the connector , at 500 watts ,or idle , rock steady , software is misleading , boot after boot ,readings will chance , ballpark at best .

Ballpark is fine however the corsair data wasn't based off a single boot but rather over a few weeks of testing and monitoring. As of today I've rebooted and power drained over 5 times and they are vastly improved in comparison after the change. With regards to the real figures doesn't bother me too much, this just helped me get to a point where I can forget about it now and I appreciate HWInfo for that but also blame them from making such a thing visible in their software. :)

inaccurate readings are still inaccurate be they for a day or week or year. If the app is pulling the data off the mobo the readings can be and often are inaccurate. I had a PSU once that had according to HWInfo a 12v rail that was way out of ATX spec, multi-meter stated otherwise as did the fact the PC was running perfectly fine and showing no power issues.

Thanks, I guess my point was I saw a difference that got me out of the rabbit hole.

Also the testing I did wasnt just time based. I tested different combinations of the 9 PCIe ports on the corsair which showed varying but consistent results in HWInfo. I also have access to 3 different 12vhpwr that showed varying but consistent results. Also tested sleep and power on states which showed consistent results depending on scenario I tested. All of them did not make me a happy man, I switched PSU and saw these results massively improve, that to me is enough to get me out of the rabbit hole, software will at least be good enough to tell me if something has changed based on the testing Ive done myself.

To top it off I have evidence that readings in HWInfo will tell you if the connector youre using is fooked because my connector was damp from rebuilding my waterloop I thought I had given it enough time to dry, checking HW Info by chance my rails suddenly dropped to 11.5 and 11.9 while gaming from the usual 11.7 to 11.9 I pulled the cable out and voila it was starting to burn. I would not dismiss software readings and the changes within it nor tell anyone to as it saved my 5000 AUD card. Its also more reliable than a clamp meter, FLIR gun or whatever tools people use for this insanely POS connector since you can keep it running in the background 24/7 to give you alerts if the readings change enough from your usual. No I will not open my case and calibrate a clamp meter which can also be user error prone just to test it every now and then, HWInfo is our best chance at preventing damage from my perspective because the point is to look for changes. Positive change means positive change.

ATX 3.0 standard is actually better aside from the H++ connector, if you by the specs, all ATX 3.0 meets the 3.1 standard. There's no ATX 3.2. I would get a AXi or HXi so you can monitor if the PSU drops the voltage or the cable. My mobo says +12V is 12.076-12.172V, gpu PCIe 11.974-12.105V, 12V-2x6 11.996-12.112V, while PSU says 11.984-12.047V. Not sure how the voltage is higher than the PSU readings.
Even +11.16V is still within specs.

What i wanted to know is the native gen 5 header on https://www.microcenter.com/product...-plus-titanium-atx-fully-modular-power-supply
can you use the new cable in the header for 50 series ?

Yes, I have 1600watt version, got my PSU from Microcenter .
Dear Harmon,

Thank you for your reply.

The PSU is ATX 3.1 and PCIe 5.1. Intel simplified the naming of ATX 3.1 to ATX 3 and PCIe 5 to avoid confusion. Therefore, our PRIME TX-1600, which follows ATX 3.1 and PCIe 5.1 standards, will include the 12V-2x6 cable and connector on the PSU side. You can check the connector on the PSU; it should have shorter sense wires and longer power pins. The packaging will also feature a 12V-2x6 logo to differentiate it from previous ATX 3.0 and PCIe 5.0 (12VHPWR) versions.

If you have any other questions, please let us know.
Thank you.

Native cables are better, but if you have a very high quality ATX 2.4 PSU already there's no need. Older high quality PSUs are still better than newer ATX 3.0/3.1 that are lower quality.

None of this particularly matters too unless you plan on getting a 4090 or a 5090.
 
the problem is the card, not the cable.
there is no user error, "wrong" cable from "i don't like this brand because i don't have it" or any other factor than NVidia saving 20 cents and make their overpriced trash a fire hazard.
the 3090 Ti for example doesn't have these issues since it has a proper implementation of the 12VHPWR connector.

There have in fact been many user reports of problems with third party cables but not stock ones.

That may be the case with some cheap Temu-level crappy cables, but I'm pretty sure that 99% of the cases, it's just Nvidia blaming everyone for their faulty cards instead of admitting that it's their fault.

You can believe whatever you want to believe, but cablemod etc are these "temu-level crappy cables" in your mind?
