430PSU compatibility with RX 570

Stupid question here.

My current build uses a Corsair CX 430 PSU bringing power to it. I have an RX 570 waiting to be installed and replace the pitiful 750ti inside of it. But I'm hesitant if I should do it now or get a higher wattage PSU.

For reference, my build is comprised of the following:
FX 6300 CPU
ASRock 970 Pro 3 R 2.0 mobo
8 GB of DDR3 RAM (Crucial Ballistix Tactical 4GB x 2)
Random Seagate 7000RPM 3.5in drive (1tb)
Some 3 pipe cooler with a 90mm fan
2x 120mm case fans

Under these conditions, would the PSU be adequate to power the RX 570? Or is it not enough.

If the latter, do y'all'mst have any good suggestions for a suitable PSU?

  1. Best answer
    rx 570 120W
    fx 6300 95W
    Rest is ~ 60-70W
    <300W, times 1.2, 400W should be enough. But your psu is not every reliable, suggest this:

  2. I would replace that PSU, it is a low quality unit.

    Corsair's new 2017 (Grey label) CX series is better quality. I'd go for the CX550 or better.

    Or either of these:
    SeaSonic S12II 520 - https://www.newegg.com/Product/Product.aspx?Item=N82E16817151094&ignorebbr=1&nm_mc=AFC-C8Junction&cm_mmc=AFC-
    Seasonic S12II 620 - https://www.amazon.com/dp/B003BIEOCI/?tag=pcpapi-20

  3. Cool. Thanks for the suggestions and answers. I ordered a new PSU - Corsair's VS500 - and it should be arriving here tomorrow.

    In the meanwhile, would I encounter any problems if I installed my RX 570 to my computer with current PSU for a day or two? Or should I just wait.

  4. Does your RX 570 require an 8-pin or an 8-pin and a 6-pin connector?

    Why did you buy the Corsair VS500? VS and older CX are the lowest quality units Corsair make, which are lower than some other brand's lowest quality units.

  5. 8pin.

    Bought the VS500 because an article on the site said it was one of the most reliable PSU's from this year. Looks like I will never take them seriously again. But at the very least, the CX managed to last me more than 3 years so I will probably look into another PSU in the near future.

  6. Then I would return the VS500 for a refund and get one of the units recommended above. They all have 5 year warranties.

    Looking at this PSU Tier List, the VS series is worse than the old CX series. https://linustechtips.com/main/topic/631048-psu-tier-list-updated/

    In the mean time you can use your CX430 but don't do any overclocking or anything like that. And don't put it under load for long periods of time because it could overheat and fail.

    Get a PSU with a 5 year warranty. That usually signifies better quality. The SeaSonic units mentioned are older so they're cheap in price, but they are much better quality.

    That's the worst PSU Corsair makes next to the old CX units.

    Return the VS.

    I would go with one of the units that was recommended as they are MUCH better than the VS.

  8. You should have just kept your Corsair CX430 and did nothing! The power consumption of your rig will be around 180W when gaming. Instead you ordered something worse - the VS550.

    And the S12ii EVO isn't very good either, it's close to the CX 430 in quality. It is also group regulated, it has worse protection circuitry than the CX430.

    This is all just fear-mongering.

  9. An RX 570 can draw 180W by itself when overclocked. He's had his CX430 for 3 years. It's at the end of its warranty period. I would still recommend a new power supply of better quality.

    Can you link a reference to the poor protection circuitry of the S12II?

    Doesn't matter, it should be fine. He wasn't loading it high with the 750Ti. Corsair warranties are rated for 24/7 use at the rated temperature at 100% load. This is what Corsair's PSU manager says.

    The reviews I'd have to find, I believe one was maybe on bit-tech, but the S12ii has no overcurrent protection on any rail and no undervoltage protection on the 12V rail. This is a fact, hopefully you'll take my word for it, if not you can go on the Jonnyguru forums and ask about it and Stefan Payne will point you out to the specific reviews.

    Plus the S12ii are loud as rockets past 300W, in the review on bit-tech (I believe) it got to 60dB at full load.

  11. I did find them http://ru.gecid.com/power/seasonic_s12ii-520_bronze_ss-520gb_2015/?s=all

    https://nl.hardware.info/reviews/5926/seasonic-s12ii-v2-520w--620w-review-met-nieuwe-fan

    And these review are more relevant since they test the 2015 version, or the current one.

    Don't get me wrong, I still think the S12ii is a good PSU. It's just not that much better than the Corsair CX430, and both are better/worse in certain aspects.

  12. Yes I was just reading up on it, it's right there at the bottom of the first page of JohnnyGuru's review of the 520. I didn't realize there was a difference in OCP and OPP. Now I know :)

  13. OP here. I just recently installed the RX 570 into my computer using its current PSU, the CX430. For the most part, everything worked; the computer powered on and the video card worked fully intended - it was nice seeing Dark Souls 3 maxed out. However, after 40 minutes of uptime the video card drivers began crapping out. Also, one of the fans in my computer would go full-blast during a cold boot after a crash.

    I could chalk it up to a variety of reasons, but I meticulously removed all of the previous video card's drivers before installing the RX 570. So I'm going to assume the culprit is the power supply because it's had some problems in the past, namely that it fails to load all video card drivers after a cold-boot and requires a warm-boot to get everything working normally.

  14. Power supplies don't cause video driver problems, that is a software issue. The fan issue would also be unrelated. Sounds like lots of software problems you got.

  15. Agree with turkey3, PSU will not affect drivers

  16. Really? Because I reinstalled my 750ti and everything is functioning perfectly. Up for several hours and no crashes and I didn't even have to use DDU this time.

    I did notice from earlier that my CPU got really hot with the RX 570 installed. The CPU's average idle temps on the RX 570 was 28~30C, whereas the average idle temps in conjunction with the 750ti are in the single digits. I couldn't keep track of CPU temps in game, but I do imagine the temps increased exponentially with the RX 570 installed. I kept track of GPU temperatures on both the 570 and 750ti, and so far they managed to maintain normal temperatures.

    Sorry for any of my autistic speculations. I want to isolate any problems before the Seasonic arrives on Tuesday. I sincerely hope this is not a bottlenecking issue. I really don't have the money for a Ryzen upgrade, and my mobo is trash with 8-core FX processors due to Assrock's VRM throttling.

    I am highly doubtful your temps are in the single digit unless you have your PC outside on a cold day.

    I mean, who knows, maybe a clean install would fix the problems?
