Which one? new PSU... again :p

Recommended Posts

Posted · Original PosterOP

Edit: Well guys, it seems i was wrong while looking for >700w psu's, my computer doesn't need such power nor will take advantage of having too much wattage, what i need is 500w or 600w tops nothing more, you can read all the fuss in case you are like me, someone who wants to buy overkill psu's to power up potato pc lol.

Hello there, few weeks ago i made a topic asking for help to choose some cheap reliable psu, the EVGA 600 GD (2019) was the winner but the store where i get my stuff run out of 600w version ? so the only ones i have left to choose from were Cooler Master MWE 650 80 bronze and Gigabyte B700H 80 bronze as well BUT...

I was thinking "cmon man, you can get something better..." so i was checking and i can get the next PSU's:

Corsair 750w TX750M 80 Gold, semi-modular - part number/id: CP-9020131-NA (Tier A)
Corsair 750w RM750 80 Gold, fully modular - part number/id: CP-9020195-NA (Tier A)
EVGA 650w 650 GQ 80 Gold, semi modular - part number/id: 210-GQ-0650-V1 (Tier B)
EVGA 700w 700 GD 80 Gold, not modular - part number/id: 100-GD-0700-V1 (Tier B)

Each one have very good reviews at newegg, amazon and random websites, i'd say RM750 looks like the best choice but there's no way my potato can take advantage of 700w, according to psu calculator sites and LTT users like GoldenLag and rares495 my potato should be fine with any good 500w psu (Ryzen 1300x, 2x 8gb ddr4 ram, GTX 1650 Super, 1 HDD 1TB, 1 SSD 500gb, dvd-rw drive, hyper 212 evo cooler, 2x 120mm fans with rgb, front usb 3.0 panel) but i could always add more fans, rgb and gonna upgrade potato CPU in few months also can't find good psu's below 700w nothing beyond bronze or refurbished and good price, so what do you think?

ps: hmm it seems RM750 has two versions, one very old from 2013 or something with RM colored yellow and 2019 version with all letters colored white & grey.
BTW im very sorry if im breaking any rules by making a 2nd topic wiht almost the same subject, 1s one was about cheap reliable psu's.

This is correct. The part number you listed for the RM750 CP-9020195-NA is for the new 2019 version.

 

What are the prices of each?

Your system will only consume like 200W... The GTX1650 is a very low power consumption card and the Ryzen 1300X doesn't consume much power either.  The other stuff like a single HDD and single SSD hardly consumes any power.

 

Are you buying from stores that have a website where we can see what is available?

That system even runs on a 300W psu. Even with a 3600 and a 2060s and a ton of drives my system draws under full load only 270W, so there is still plenty of headroom on a 500-550W PSU. Save some money in getting a lower power psu and put that towards upgrades. Even something like the corsair cxm450 or how this thing is called should be plenty even with upgrades. And if you dont get crappy fans or server fans, they won't draw a noticeable amount of power. Leds are very power efficient so thats a couple of watts at max too.

didn't mean to say lower tier but lower power psu

Do they also happen to have a TX550M or an RM550x? 

Your system could legit run on a 400W PSU, as it won't consume more than 200-225W even at full load, but 550W is a good sweet spot as in your efficiency won't be as low as if you were to go with a 700W+ unit, and it will still be plenty for CPU/GPU upgrades in the future.

I wanna give a good retirement to my 7y old Antec 520w High Current Gamer HCG, it's been working for countless hours with no problems so far (thank god) and powering different systems (my old AM3+ potato), that's why i was looking at 600w> or more powerful psu's but it seems i don't need such power, the problem is that i can't find good 500-600w psu's and when i do find something good the price diff is so ridiculous that makes me hesitate and think twice before hitting that "BUY" button eg: EVGA 500w GD vs 700 GD price difference is about 15 dollars, i'm a newbie and when i see the RM750 for just 110 dollars and then EVGA GD 500w for $75 makes me want to pick RM750 over non-modular and less powerful units ?

But but... the psu calculator sites... ? saying i consume over 350w and that i should pick 600-650w psu's 
That's not the worst, somewhere i read GTX 1650 and 1660 draw as much as 200w+ at high loads while gaming, is it true or im just a dumb newb and i got confused with the GPU max load and the total system power consumption
OMG this is like someone who just needs a glass of water but wants to drink a whole galon instead, so 600w that should be tops right? 700 is overkill and i loss efficiency, sounds like having RM750 running with my potato is kinda dumb anyway im going to search for 500-600w psu's right now.

btw nope, can't find either TX550M or RM550X.

Big problem is that im from mexico, here the hardware price is ridiculous, sometimes is cheaper than US (idk why) but mostly way more expensive, i have to pay 75 US for the EVGA 500w GD and this is the funny part, the price for RM750 is 100-110 US thats a big what the .!"#! 
I'm looking everywhere in the mexican amazon and this "mercado libre" website (Very famous in latin america it's like bestbuy or newegg) plus many online stores, the best i could find was Corsair CX550M and Corsair CX650 both 80 bronze and well they look meh, i think both are tier B and B+ im gonna call tomorrow to make sure those are not refurbished psu's (there's something very weird here in mexico, most Corsair psu's being sold as refurbished idk why).

Yes, they'll probably talking about system power consumption, not the power draw of the graphics-cards.

Yeah, don't trust those calculators.

The GTX 1660 will max out at around 125W, and the 1650 probably below 100W.

Out of the units you've mentioned, probably the RM750 would be the best option - it's fairly similar to the RMx series, except for the fan that isn't as quiet as the one on the RMx, but it also has the zero RPM feature (fan won't spin until a certain load) so I still wouldn't worry about any noise.

I still disagree on >550W (o.k., max 600W), there has to be a viable option somewhere. And $15 not spend is $15 saved, no matter where and why, you do not get any benefit on higher psu-wattages.

 

And the Antec (Tier C) did well so far, it's just at age. They don't have the very Antec any longer?

lmao that's the very reason why i was looking for >600w psu's oh god .... so there's no way this 100w card (gtx 1650 super) can draw over 200w or more power and the whole potato takes like 300w or less, jesus christ, i should change my nickname to "derpyburrito" asap, so my potato is ok with any good 500-550 psu, now i have to find something worth the price, if i can't find a good Corsair below 600w i'll wait and get the EVGA GD 500w or 600w (as GoldenLag told me to jesus that guy must think i do drugs or somethign).

nope, unfotunately can't find Antec psu's anymore, it's almost like the company didn't want to sell anything ever again in mexico, sure you can find some but not like evga or cooler master, they are everywhere plus plenty of rebranded chinese psu's. (also Rosewill and Bequiet are non existent here, that sux) 

And yeah this psu did very well, 7 years and still rocking, i hope my next psu last as long as this antec, seven !"#!$@ years im proud of this lil guy? but it's time to retire him and have it as backup in case of new psu malfunction or just to power up old potatos like my hewlett packard pc from 2007 lol loaded with games like warcraft 3, age of empires, jedi knight II and more.

Mercado libre mx, is it correct that I would have to divide the number by 20 to get a value I can compare to the US$-prices?

yeah i think so, lets take the evga 600 GD at "mercado libre mx" cheapest one from reliable seller is worth 1899 mx / 20 = $94 dollars, RM750 would be $116 give or take few bucks, EVGA 500 GD price is $73.
CX550M = $63
CX650 (non-modular) = $66

On Mercado I saw a few eVGA BR, which - as beeing Tier C+ - should be suitable for you as well - if cheap. 

And Corsair CXM (semi) modular. They're good, Tier B, and not so expensive. (450/550/650 is Tier B, 400/500/600 Tier C+).

 

CX550m for $63 sounds good to me.

Almost a month later im so sorry...

I think im getting the CX550 or CXM550 according to psu tier list the CX550 is Tier B+ thats even better than EVGA 600 GD gold (tier B-)

To everyone else what do you think guys? CX550 or CXM550

Do you want a semi-modular power supply? Then choose the CX550M. Otherwise the CX550.

yeah i like the CX550m semi-modular design but i've been reading about it right here in linus forum and CX550 is slighly "better" or that's what it seems...

"the cx is a LLC Resonant, the cxm still double forward" (LukeSavenije) then another guy said CX is preferable over CXM but nothing else.

BTW is there any page with CX550 & CX550M full specs? corsair official site doesn't mention anything about protections (OPP, OTP, SCP...)
