Hello everyone longtime lurker,first time posting!Ok i have bought a XFX 580 8GB GTS,before that i had a 1060 3gb.I know that this gpu is more power hungry,minimum req. for it is a 500w PSU,but the real question is can my "unknown" PSU handle it?I have the GPU with the PSU for a week now,i didnt notice any strange noises or anything while playing games,max power the GPU was using was 150w.PSU is 3 months old only btw.Here are the specs

i5 7400
1x8GB DDR 4 2400
MSI H110M ECO
RX 580 8GB XFX GTS
1 TB Hard and 120GB SSD

Ultron RealPower RP500 Eco 500W 80 PLUS BRONZE

Power supply is fairly not known,it is manufactured in germany and sold around central europe only,you rly cant find much info about it,thats why im a bit scared.

sorry for misspelling,and thank you in advance!

Here's the only decent information I could find of the 600w version (should be similar): https://us.hardware.info/product/229757/ultron-realpower-rp600-eco-silent-600w/testresults

From 50w to 100% load the 12V rail drops 520mv! This isn't even crossload tests, being more realistic, that number could double. Very crap voltage regulation. Ripple at 100% load is 92mV - although in spec it is a very poor result. These numbers only become worse with age. It can lead to system instabilities and shortened component lifespans.
It is pretty inefficient and loud.

These are simple tests which lack crossload, transient response, hold up time, inrush current, EMI, and protection testing, so more flaws could very well be hiding.

The manufacturer...

it could run, but you are likely to run into issue with it.
The 12v has two rails 16a and 17a each.

580 is quiet power hungry, for it to run on any of the 12v rails with 16a seems to little.

you want a single rail of 35A plus to be able to handle the system properly. unless you can hook up both rail onto the same card, which i don't hink you can, (rx580 only uses 1 8pin).

Thank you for the fast response,im just afraid that it will damage my components,hopefully not...ill try to get a better power supply in few months and hope nothing happens till then :)

They suggest their own XFX 550W PSU because they don't sell a 500W model. The Minimum Power Supply Requirement 500 watt spec is what matters.

Minimum of a 500 Watt or greater system power supply with a combined +12 Volt continuous current rating of 33 Amps or greater and with at least one 150 Watt 8-pin PCI Express supplementary power connector. (Minimum system power requirement based on a PC configured with an Intel Core i7 3.2GHz 130 Watt TDP processor.)

@djxtra.gaming has a 65W TDP processor so the 33 Amp requirement can be dropped down to 28 Amps.

Sorry ima bit green on that,so does that mean that my PSu kinda can handle the Rx 580? atleast for a while,yea my PSU has 1x 6x2 connector only

Im ok with "little"issues im just afraid if it decides to die,that it will take all the components with it,since ima bit short right now with money to get a new PSU right away maybe in a month or two,i can get a new one,better quality one.

ultron's RealPower RP-500 ECO specs say that it has 1 x PCI-E 6 + 2 connector. That is the 150 Watt 8-pin PCI Express supplementary power connector so it does meet the minimum requirements.

I don't know if there are any PSU issues I would call "little", the best case scenario ones would be spontaneous crashes/reboots.

I can't find any reviews of that PSU, and the manufacturer product page/datasheet don't list any protections (e.g. overpower or over current protection). There's not much that inspires faith that it wouldn't take other components with it (or even burst into flame) in the case of a failure.

I agree, the only thing you should do with that PSU is take it to the nearest electronic waste disposal place. It should definitely not, under any circumstances, power a rig with a i5-7400 and a RX-580.

Thank you all for your help i rly appreciate it,i know its a pure junk PSU it was good for the 1060 3gb i had before,and i know with 1 stick of ram im leaving out performance but that is what i could afford,im slowly upgrading it 1 by 1,first the gpu cause i got it for rly cheap,now the PSU soon and another stick of ram and the rest etc.Thank you all

The manufacturer doesn't mention of any sort of protections, obviously no pride there. It likely lacks many.

An aftermarket RX 580 can consume ~20A from the 12V rail when under load. Your PSU has just a 17A rail at best.
Although they could just be lying, where no OCP for the 12V rail is implemented at all.

It is a "500W" PSU, but only 396W of that is important on the 12V rail. That number could've been rated at stupid conditions, such as peak values at 25C ambient. Within typical computer conditions the wattage could be much less.

Can it decrease you components lifespans long-term? Yes.
Could it kill other components when it does? Not unlikely.
Could it cause issues such shutdowns, blackscreens under load? Probably.
I doubt it will last over a couple years too.

I'd upgrade it ASAP.

We can help find a PSU if you could kindly describe
- Your case
- Your location (country)
- Your budget
- Importance of features such as PSU/cable aesthetics, noise, or modularity.
- Any upgrade intentions

Wow thank you so much for the detailed explanation and digging @Rexper,it is a crap PSU for sure,i was able to buy just a hour ago a new PSU thanks to my wife (since im curently unemployed) cause i was a bit to afraid now to leave it like that,especialy since i got the rx 580 now.I was digging around and took the suggestion from @logainofhades that replied on my topic,and bought the corsair cx550m that i could afford it costed me 75 euros,dont know how the prices are elswhere,but considering the paychecks you get here in Croatia PSU are kinda expensive if you want to get a decent one,they also had corsair VS550 and VS650 that where 10 to 20 eauros cheaper then the cx one that i bought,but i have read here and on other forums,that those two models are not that good compared to cx ones.Stores around here have only some generic unknown PSU like i had,few corsair models.few antec models rarely any seasonic models,and the most here that are on the stock are FSP or some Silence PSUs.

I was actually thinking should i take the Corsair cx550m or for the same price some ZALMAN ZM700GVM,but i took the corsair one in the end.

Yes that is a wise choice, the Corsair is definitely the better unit of the two.

Doesn't matter if it meets the minimum requirements or not. The key is will it work? Is it a solid build quality? Is the brand reputable? If the answer to all of these is "no", then do not buy. Any generic 500W PSU will work but the question of whether it will work *WELL* is what you got to pay attention to. If it doesn't work well it has the potential to blow up or short out on you and take your whole system down with it, then you're in far more trouble than it would be than if you paid the extra money to simply buy a quality PSU.

Think of it this way - remember that scene from the movie Office Space where Jennifer Aniston is getting grilled by her boss about "only doing the bare minimum"? The bare minimum won't cut it for power supplies, you need that and much more if you want to run a CPU and GPU without worrying if your system will blow up or short out or not.
