Cooler master 450Watt suffice for RX580?

[saadgamer_17]

I have cooler master thunder power supply which is 450watt. Can it handle RX580 4gb card.

 

[bgunner]

The minimum recommended PSU for the RX 580 is 500W.

450w from a decent quality power supply is easily enough for any system containing a single RX 580. Which exact model PSU are you dealing with here?

Click on this link, scroll down till you see "Requirements" and open the drop down menu and you will see that AMD is recommending the minimum PSU is a 500W. Now This is enough to power a standard system containing fans 1-2 HDD's, a couple case fans and an ODD But no overclocking. This recommendation is is to allow for the high spike that happens on power up when all the components get initialized. If you go to low of a wattage the PSU will eventually become over taxed and can and eventually will die possibly taking other components with it. As a PSU ages its maximum output drops this is where the issues start to happen.

IF you want to know what the exact card requires for a PSU look on the manufactures web page for it, most have it listed in the specifications for the card.

Manufacturers look at worse case scenario and over estimate when giving a recommendation. Read this professional review, even a system with RX 580 and overclocked 7700k uses around 344w at a gaming load. Times that by about 0.85 due to PSU efficiency = 292 watts. http://www.techspot.com/review/1393-radeon-rx-580-vs-geforce-gtx-1060/

In terms of wattage, the PSU should be enough. In terms of quality, that is yet to be known.

One of the big factors to this is the CPU. While this test was done on an Intel CPU what about an AMD CPU? What CPU is being used in the OP's system? While Ryzen is not power hungry the FX series is very much so. Also look at the article's test setup. No case was mentioned so you are looking at a test bench with no HDD's only one SSD ( the average wattage for an SSD is 3 W where as a HDD's average is 5-7 Watts sometime higher, multiply this by however many HDD's you have). There are no case fans added into this wattage they measured so add 5 watts per fan ( other than the fans for CPU and GPU cooling)

The recommendation is for a full system including what that article does not. Push the PSU to close to the raged edge and will cost in the end, referring to other damaged hardware. BTW warranty's don't cover damage done by insufficient power supplies (this would be considered user damaged). This fact would have to be kept secret for them if an RMA was needed. There is a reason it is listed under "Requirements".

I'm sorry But I truly feel you are giving bad advice on this one. Nothing will change my mind on that. Will a 450W PSU power a rx 580? Yes. Could it damage the card or system ? Yes What doe the manufacture recommend for a RX 580? 500 watt PSU

IF you run an engine that requires 5 quarts of oil constantly on 4 quarts of oil will damage be done? Eventually yes it will. same here. As a PSU gets older its ability to put out the labeled wattage and Amperage decreases. This and other factors go into the manufactures recommendation for a PSU, to give the optimum life span and performance over that time.

The FX 9590 uses about 60 watts higher than an overclocked 7700k whilst in high load: http://www.legitreviews.com/amd-fx-9590-8-core-cpu-review_190566/9

For the sake of it, lets just assume OP is using 4 HDDs (4 x 7w) and 4 fans (4 x 5 watts) (highly unlikely).

With the starting point of 292w, we add the less efficient CPU, HDDs and Fans.
292 + 60 + 28 + 20 = 400 Watts which is still doable on a high quality 450 PSU, which is why I asked OP for it's model.

Overall, it is most likely fine in terms of wattage. Though just to be sure, it is best OP provides system specifications.

Whats the brand and model? if its not any of those cheap china brands it will work fine.

Lets use this bench test as the MSI RX 580 power consumption, since it is an MSI RX 580. https://www.pcper.com/reviews/Graphics-Cards/Radeon-RX-580-8GB-Review-Polaris-Populism/Detailed-Power-Consumption-Testing

Now lets take the worst case scenario of the GPU using a 210 W in Metro Last Light and add the FX 9590 that has a draw of 200 + watts lets say 220 watts the Cooling system needs to account for already you are pushing 430 Watts then add in, lets use my PC as an example, 7x extra fans that's 35 Watts, now you are looking at 465 watts total then add 3x HDD's for 21 watts and 1 SSD's for 4 watts making the total up to 490 Watts then add ram at 1.5V = 2.5W per module X4 = 10 w making the total now 500W not including the motherboards consumption or the ODD if one is used. If liquid cooling is used add wattage for the pump, 1 fan for the cooler is included in the motherboard usage.

http://www.buildcomputers.net/power-consumption-of-pc-components.html

Now lets say there are less components, Can you keep the power consumption under 450W quite possibly but also pushing the PSU to over 80% of its maximum out put also has a down side effect of using more electricity. the sweet spot on most PSU's are between 50 -80% of max. Under this they are less efficient and over this the same.

GPU = 210 W
CPU = 65 - 220 W / depending on the CPU
Ram = 2.5 W / stick
HDD = 7 W / drive
SSD = 4 W / drive
Fan = 5 W / fan
ODD = 15 - 27 W / Sata CD/DVD drive
ODD = 25 - 30 W / Blue-ray drive
MB = 25 - 40 W for Normal motherboard
MB = 45 - 80 W for a High End motherboard
Peripherals 3 -7 W / device

Basic set up
Motherboard = 35 W
CPU = 95 W
GPU = 210 W
Ram = 5 W ( 2 sticks )
HDD = 7 W
SSD = 4 W
Fan = 5 W ( only one on the back of the case)
ODD = 22 W
Peripherals = 10 W ( mouse and keyboard only)

total power for a basic system is around 393 W. But this does not include any extra peripherals like a camera, game controller, only includes the rear case fan and no other case fans, only a single storage drive rated for efficiency and under 2 TB since over this they seem to hit 10+ watts, No lights if you choose to install them. Everything depends on the OP's setup, whom we still have not heard from concerning the other parts of the system.

At this point everything is just speculation as to if it will suit the OP's system/needs or not.

I am sorry that you feel this is getting stupid , unless you personally know what the OP's system configuration is ( please share if you do), There is no way of knowing IF a 450 Watt PSU will be enough to power his needs. SO to say that and I quote "which is 99% irrelevant to OP" you really do not know what His/Her needs really are. The best we can do is give all the information we can so the OP can make the best informed decision on what will work for them.

Actually TDP (Thermal Dissipation Power) is not the max heat it can put out but what the max that the manufacture says the "Cooler" needs to be designed to dissipate at stock settings to keep the CPU cool. Now If you overclock the CPU the TDP is no longer correct since the CPU's Heat output increases. So the rated TDP is not the MAX heat output the CPU will put out But the rated heat output of the CPU at full stock settings. SO if a CPU is rated for a 125 TDP the stock cooler, or aftermarket cooler if used, needs to dissipate 125 watts of of heat to keep the CPU cool. Now overclocking the that CPU can easily generated 50 - 75 more watts of heat that needs to be dissipated.

"The thermal design power (TDP), sometimes called thermal design point, is the maximum amount of heat generated by a computer chip or component (often the CPU or GPU) that the cooling system in a computer is designed to dissipate in typical operation. Rather than specifying CPU's real power dissipation, TDP serves as the nominal value for designing CPU cooling systems.[1]"
