[SOLVED] Can i do this

[Eneil]

Hey i was wondering if anyone knew if it is possible to run an rx580 8gb on a 500 w psu my current system is a i5 10400 a nzxt kraken aio 240 western digital ssd a 500 gb hard drive. Do I need a bigger psu?

 

[hotaru.hino]

Without knowing the model of the PSU or how old it is, as long as you have enough PCIe cables that the card requires, it should be fine.

 

[ex_bubblehead]

Seeing as the rx580 alone requires a 500W PS then no, you will require a much larger PS.

 

[Sick Jacken]

No, by any means no. If it's at least 80 plus bronze, i'll hold that system plus another 3 HDD's as well

what? the doesn't require a 500-watt power supply alone. It has a tdp of 185 from what I can find. Depending on the model a 500w would probably be fine. What model is it?

AMD themselves recommend a 500w PSU.

500watt PSU for the total system! Here recommended 550watt http://www.realhardtechx.com/index_archivos/Page362.htm

Yeah but that means for a whole PC with an rx 580.

 

[Ralston18]

If a GPU manufacturer states a recommended PSU wattage that is the wattage value I use for the GPU itself.

They have no idea what else may be installed and any manufacturer provided wattage values were probably established on paper and/or ideal testing circumstances.

Agree, may necessitate the installation of higher wattage PSU but there is no harm in that. The system will only use the wattage it needs and having extra wattage available is always a good thing.

Just my thoughts on the matter.

Two things should be noted:

• Look carefully at the wording or any footnotes regarding power supply requirements from AMD or NVIDIA. For instance, in the case of the RX 580, AMD "recommends" a 500W power supply. They do not "require" a power supply at that range. And while NVIDIA has started saying "required" for the 30 series, there's a footnote that says "Requirement is made based on PC configured with an Intel Core i9-10900K processor. A lower power rating may work depending on system configuration."
• The number power supply calculators give you may either be the wattage of power supply you should get, or some really worst case scenario of how much power the parts will consume. The last time I used a power supply calculator (Outervision's), I could not get my system to consume half of the what it reported, despite throwing on what I thought was the most realistic demanding workload I could on it.

As an anecdote, I ran a system with an i7-6700, a GTX 1080, a hard drive, and an SSD with a 450W SFX power supply for about three years before I built a new computer. The computer wasn't pulling more than 250W from the wall at any given point.

Heck my current system with a Ryzen 5600X and RTX 2070 Super still rides under 250W from the wall (granted I tuned both for efficiency). I could put a quality 500W PSU in there and it'll run fine despite NVIDIA "recommending" a 650W one for the card.

I think you will be close might depend on the quality of the psu your talking about.

Let's find out if the OP has a competent PSU or not and then we can decide whether we need to pointlessly argue with each other about the description of power requirements.

OP, here's the lastest list of good to barn burner power supplies to find out what you have from a quality standpoint.

Please reply here with your model so we can all put this to rest. Some will toss and turn all night and check their notifications until you do...

Lol toms and power supplys you all must really think that stuff is going to lite on fire. If you have seen the things I have done over the last 10+ years you would all have a heart attack. Never once blew a psu or had a fire.

If the psu is even remotely decent OP is not going to have no issue get over your fears toms.

i also trusted a deluxe 450w once with a gtx 280

People successfully drive drunk, too. That they got home didn't make it a good idea.

 

[Sick Jacken]

pc's aren't that complicated, legacy star bios ms once had poor capacitors.. and by poor i mean undervoltage and not even going at kw, a cmos battery was far powerful than the latest ga series plus those towers with gigantic exhaust left side case blue leds, back when gigabyte mb used to be sold under the signature of "GA" anyhow.

2000's were a year, i vivdly recall 2007...

I run a 3070Ti on a 750W PSU with a 12700k and never had any issues, and neither had I ever any issues with my old system featuring a 1070 running on the recommended 500W PSU. It's just bs that the recommended(!) 750W PSU isn't enough...

Ps: if unsure, look at PSU calculators. Hint, they usually show very similar values to GPU manufacturers... wonder why.

Nobody here cares if you do stupid things. We don’t like to hand out bad advice to those less knowledgeable. Fact that you haven’t burn down your house yet still does not make it a good idea—as stated above—but if you like doing stupid things go right ahead

I’ve seen PSUs destroy computers mobo cpu etc. It doesn’t necessarily have to burn your house down to hurt you. It can blow up your computer and your computer components

This above is from AMD's website so if OP has a reasonable quality 500watt he is with in specs.
Total system power consumption is well under 400watts https://www.anandtech.com/show/11278/amd-radeon-rx-580-rx-570-review/16

All this fighting about 500w being enough and the OP hasn't even come back and stated whether hes using a $20 White box or a real PSU. I think we all overestimate the house burning down functionality of many PSUs on the market. Instead of being dramatic lets let this argument die until @Eneil comes back and tells us the exact make and model of their PSU.

If its a 500w even marginal brand PSU it will work fine. You do not need a lot of wattage to run an RX 580, and going WAY over spec just wastes efficiency and money.
