I am dilemma is power supply named Zeus from 700w any good fora system containing CPU: AMD Ryzen 5 2600, GPU: MSI Radeon 570 8gb and motherboard b450 ? I have searched over whole internet and couldn't find any info on this PSU ... Thank you in advance for any valuable information :-)

I think you are referring to the Zeus ZUS-700 700 watt power supply.

I could not find any reviews either ... only very basic information/specifications from sellers. From the pictures, the Zeus ZUS-700 looks like a very generic PSU, that comes with 20+4 pin, 4+4 pin, 3x SATA , 2x molex, and 1x 6-pin PCI-e cables. I can't tell for sure, but the old molex cables and it just having one 6-pin PCI-e cable (for a 700W power supply) tells me that this is likely a very old design. And my assessment is that this is a very cheap power supply -- and probably not good for what you are looking for. I do not recommend you buy this.

BTW, what country do you live in?

That unit isn't even rated 700w it is only 564W MAX.

I live in Serbia so there is a lot of bad power supplies and the one that have 80 plus certification are expensive... The components i have are bought in USA and now feel bad cuz i didn't get PSU there too. Thank you for elaborate response :-)

No review about the psu means stay away from it until there is one.

Can you post some shops in your country where you buy from? Just to see what they have and ofcourse your budget in your currency.

https://www.emmi.rs/napajanja-i-dodatni-ventilatori.10.html?categoryId=219 this one is one of the cheaper stores https://www.gigatron.rs/napajanja




and the budget would be around 7000 rsd but tell me if u find something that is worth way more than PSU-s found in that price range :-)

97% of those psu's that they are selling are absolute crap and should never be used in a modern system.

Lowest i would go is https://www.gigatron.rs/napajanja/cooler_master_napajanje_mwe_gold_550__mpy5501acaag-151546 .

I know its 50% over your budget but the psu is the most important part of your pc. A bad psu kill everything in your system while a good one sort of protects it.

That isn't quite enough info to go on looking it up, but that name and wattage just makes me think gutless wonder.

The cheapest decent enough PSU I recommend is the Corsair CX450.

For a bit more you can get the CXM series and have some removable cables for better management.

The TXM series often goes on sale and is a good option as well.

Then there are units like the EVGA G2/G3, Seasonic Focus Plus, BitFenix Whisper M, stuff like that which are pretty good.

The only way to know whether a PSU is any good is to actually do a suite of tests and tear it down. Jonnyguru, for example, has excellent reviews of PSUs.

RealHardTechX has a good database of reviews as well. They source many different testers.

thank you i will look into it :-)

stef123 submitter 1 point 2 months ago

Thank you for detailed response , but is 450 watt PSU strong enough for this build i mean it says on build that 450 watt is minimum and i am not sure if its ok to go for min wattage...

You can run an RX 570 and a 2600 on a good 450w power supply. The build will likely draw somewhere around 300-350 watts when both CPU and GPU are running hard.

If it's similar to this one, it seems like a garbage unit to be honest. :-P

legomaster 6 Builds 1 point 2 months ago

It does not even say the rated amps on each of the rails.

mark5916 1 point 2 months ago

Yeah it does not say anything to be honest. lol

It says only the AC input amperage of 8/4 Amps.

So actually not any info about the Max DC output amperage, combined wattage, working temps etc etc.

So just a pile of junk if you ask me. :-P

If that's the PSU in question, i would just throw it away and then i would feel much better.

stef123 submitter 1 point 2 months ago

Thank you for response :-)

mark5916 1 point 2 months ago

If that's the unit in question, do yourself a favor and buy a new PSU. :)

what do u think about this one? 800W Raidmax Cobra RX-800AE

legomaster 6 Builds 2 points 2 months ago

Still horrible. Whats your budget for a PSU?

stef123 submitter 1 point 2 months ago

It's around 50$ but can go a little more expensive if stats much more better ...
