Will this power supply work?

SubaruWRX244 · Sep 9, 2017

Was looking for a cheap power supply to go with my RX 580 CF along with a Watercooled Ryzen 1600. Thanks

Is it enough?

You shouldn't cheap out, you should get a high quality PSU because that EVGA stinks. What RX 580s are you getting?

Im getting two of these https://www.newegg.com/Product/Product.aspx?Item=N82E16814137135&ignorebbr=1
I dont think there is anything wrong with the PSU I listed but what do you think?

jankerson · Sep 9, 2017

That is a Low end PSU.

As was posted you need a better quality one.

SubaruWRX244 · Sep 9, 2017

jankerson :

Well which one? I need it to be plenty powerful. I cant go over $80

You don't need to think when I know

It's not a good power supply at all. It;s a cheap group-regulated unit with a crappy fan that only has two 8-pin PCIe cables. 750W power supplies should have 4 PCIe cables, it's just an example of a power supply that's majorly overrated and beat out by better 450W units for the same price.

I have data on the power consumption of an overclocked RX 580:

__________________________________
Hardware: RX 580
Data on: RX 580 Nitro (Boost Mode)
Source: http://www.tomshardware.com/reviews/amd-radeon-rx-580-review,5020-6.html

Power Consumption
Gaming (average): 224.1W
Torture (average): 237.4W

So with two of those and a Ryzen 1600, you're probably looking at around 500W of load when gaming, or with overclocking more like 600W.

My first question is why are you getting two RX 580s instead of getting a single, more powerful GPU? If the PC is for mining that is understandable. If it is for gaming anybody would tell you that's a very poor decision since Crossfire is problematic. A single, powerful GPU is always the better solution.

Now, each GPU requires one 8-pin PCIe cable according to this. So technically the EVGA would work, but it's still a terrible choice.

The power supply is not something to skimp on! If you can afford watercooling (which is almost always unnecessary) and two GPUs you can dish out a few more bucks to make surew your system is not getting annihilated by crappy voltage regulation from a cheap group regulated PSU by EVGA to feed off customers through name-recognition.

Some power supply options:

Bitfenix Whisper M 750W
EVGA 750 G3
FSP Hydro G 750W
Corsair RM750x
Seasonic Focus + 750W

Our of those, I recommend the Bitfenix Whisper M 750W.

SubaruWRX244 :

May I ask why? I'll find something for you under $80 if need be, but I'm curious.

Im going for an all AMD system.... The crossfire looks very nice in the Fractal Design Meshify...... Id rather just have them over a single card. Im stubborn lol. Anyways what PSU can you recommend me?

turkey3_scratch · Sep 9, 2017

If you can push your budget by $2: https://www.amazon.com/dp/B01NCRRCRR/ref=twister_B06XD5VGTN?_encoding=UTF8&psc=1 <-- decent Thermaltake unit, even has an RGB fan if you are into that stuff.

I think a 650W unit would also work if you don't overclock too heavily, but 750W is probably a better idea.

SubaruWRX244 · Sep 9, 2017

turkey3_scratch :

Are you positive? Seems like the Thermaltake one is the best rn. Any other ones?

SubaruWRX244 · Sep 9, 2017

turkey3_scratch :

I also see this one http://www.microcenter.com/product/457278/G750M_G_Series_750_Watt_80_Plus_Bronze_Modular_ATX_Power_Supply

turkey3_scratch · Sep 9, 2017

There is the Corsair CX750M. There is the Riotoro Onyx 750W.

SubaruWRX244 · Sep 9, 2017

turkey3_scratch :

Maybe I should get a 850W PSU? Im second guessing if 750W is enough. Im going to be overclocking CPU and GPU's a tad...

turkey3_scratch · Sep 9, 2017

RX 580s don't overclock much at all. 750W should be fine. It'll run at a fairly high load but it should be fine. If you were to get an 850W PSU within your budget it would end up being worse quality than a similarly priced 750W unit. Always choose quality over wattage.

SubaruWRX244 · Sep 9, 2017

turkey3_scratch :

Okay and one last question. I can either get the Thermaltake 750W RGB one you sent me. Or I can choose from these below, which one is best here?

Ill just get the Corsair CX750M... There is a classic version and a 2017 Version? Whats the difference , thanks...

The classic vers had a lot of issues, the new CXM is MUCH better.

jankerson · Sep 9, 2017

IMO You should be looking at something like the Seasonic Prime Series 750W, you can get the Prime Series Gold for a reasonable price and with a 12 Year warranty.

But that's just my opinion.

turkey3_scratch · Sep 9, 2017

There is no proof the CX units had problems originally. Anyway the CX750M is a fine choice.

SubaruWRX244 · Sep 10, 2017

jankerson :

I still have my old Raidmax Vampire 700W Modular.... Can i just use that?

SubaruWRX244 · Sep 10, 2017

turkey3_scratch :

Might go CXM but I have the Raidmax Vampire 700W I can use?

jankerson · Sep 10, 2017

SubaruWRX244 :

Yeah if you don't like the new parts you have coming etc, go ahead.

turkey3_scratch · Sep 10, 2017

Well the Vampire's not horrible but I think buying something new would be wise. I just don't understand why you'll spend so much money on the rest of the computer but don't want to pay for a PSU.

SubaruWRX244 · Sep 10, 2017

turkey3_scratch :

Well I mean I have the Raidmax Vampire one.... I mean I can't justify spending more than $100 just for a power supply... But I think I found the best PSU for the Price..... https://www.newegg.com/Product/Product.aspx?Item=N82E16817438060
I think ill just get thus PSU and call it a day. Or I can spend a tad more for the EVGA 850 G3....
