Looking for PSU Suggestions

[Lord Letto]

Hi, just found out today that my old OCZ GameXStream 700W PSU got problems & needs to be replaced so I'm looking for options on what to get as a replacement (was planning on upgrading at some point anyway, but now it needs to be done sooner than I planned).

Specs of what it'll be powering:

 

i5-2500k (Currently Stock but plan on OCing to 4.4-4.6GHz)
Intel HD 3000 (Will be installing a Asus Direct CUII OC GTX 780)
Stock Intel Cooler (Will be installing a Cooler Master Hyper 212 Plus with 2 120mm fans for Push-Pull)
2x4GB DDR3 1600MHz CL8
1TB WD Blue 7200RPM Sata HDD
500GB Seagate Momentus 5400RPM Sata HDD
DVD Reader/Burner

3x120mm & 1x140mm Case Fans

 

Looking for something in the 600W to 

750ishW range with a Max budget of $90 Canadian (could maybe squeeze a extra $10 if it's worth it for a absolute max of $100, though would prefer to spend less as money is tight right now). Here's some local options I found:

Thermaltake TR2 RX 750W for $80:
https://www.kijiji.ca/v-computer-components/kitchener-waterloo/thermaltake-750w-bronze-power-supply/1342336858

EVGA 750W Supernova G2 (Warranty replacement so new but with old cables), listed for $125 but lowest the seller would take is $90:
https://www.kijiji.ca/v-computer-components/kitchener-waterloo/evga-750-g2-gold-power-supply/1382283434?

Corsair HX750i, listed for $110 but I'm hoping the seller will take less, sent a message so just waiting for a reply back:
https://www.kijiji.ca/v-computer-components/kitchener-waterloo/corsair-hx750i-modular-power-supply/1384286905?

New Thermaltake TR2 600W for $60 firm:
https://www.kijiji.ca/v-computer-components/kitchener-waterloo/new-thermaltake-600w-power-supply/1373498091?

Brand New still wrapped Corsair TX750M listed for $120, asked what the lowest they would take and got a reply of "maybe $100?", so if $100 is the rock bottom price then that's $10 over budget, I could live with that if it's worth the extra $10 over the EVGA): https://www.kijiji.ca/v-computer-components/kitchener-waterloo/corsair-tx750m-psu-750w-80-gold-new-120/1379941817?

 

Corsair AX760 PSU & Antec 900 Case for $100 each(firm for the PSU) or $170 for both: https://www.kijiji.ca/v-desktop-computers/kitchener-waterloo/corsair-ax760w-platinum-antec-900-case/1364305130?

 

as for a brand new PSU from a store, ca.pcpartpicker.com only shows 1/2 options within my search criteria (up to $78(+tax (& maybe shipping)), semi or fully modular, 80+ Bronze or better), a Rosewill Glacier 600M or 700M, both are listed for $75 at Newegg while the 600W is $77 at PC-Canada.com & the 700W is $90+ from Amazon.

 

Of those, what would be the best to go for & any others you people can think of/find?

[Cereal5]

Your system is not very power hungry from the looks of it.

 

For sale on Newegg:

https://ca.pcpartpicker.com/product/Tc3RsY/seasonic-power-supply-ss620gm2

$79.99, ends in 4 hours.

 

Alternatively, there is this Corsair unit and another Seasonic. Not much else to pick from. The rest that I see for under $90 are generally not recommended.

[NickPickerWI]

I second the SeaSonic. Great PSU.

[lmeneses]

bruh, your pc does not need even 600w. A seasonic 550 focus 80+ gold semi mod for $60 USD (i think) should be perfect

Dude, your PC demands like 75W.... even with OC you won't breach more than 100W. Add the GTX 780 and you'll never exceed 300W.

 

Just get something like a Corsair CX550M.

Thanks for the Suggestions, out of those I'd likely choose the CX650M as the amazon warehouse got one for $66.19

The reason I was thinking 600W+ is Nvidia recomends a 600W PSU for the GTX 780 & using the outervision.com PSU calculator IIRC it showed around 600W load with 650W recomended & I'd rather be safe then sorry, I believe you people that something like a CX550M would work but with money being as tight as it is I'd rather go with the manufacturers & go for a 600W+

Urgh, no.

Why do you recommend such garbage?!

 

That piece of Hardware is on the Market for 8 Years, without any major update, in the Original Version they even lied about the +12V Rails and claimed two, when the chip didn't support it.

And the Supervisior Seasonic uses in those units, the HY-510N, is absolute horse shit.

 

And then its loud, Group regulated -> Voltages can go out of spec..

 

And we also have a Thread about that junk here:

So stop recommending an old, shitty unit...

Good that you didn't choose the ancient Seasonic. That's a really bad unit.

600W is not needed, even with a GTX780, without OC you'd better look for a good 400-550W PSU.

With OC, 550W is enough.

 

A good unit would be this:

https://www.newegg.ca/Product/Product.aspx?Item=N82E16817376010&cm_re=Bitfenix_Formula-_-17-376-010-_-Product

 

IF you want modular:

https://www.newegg.ca/Product/Product.aspx?Item=N82E16817376007&cm_re=Bitfenix_Whisper_M-_-17-376-007-_-Product

 

[BigDamn]

Don't buy just based on the wattage, look at the efficiency too. If I stress both my Ryzen 1700 (OC @4ghz) and GTX 1080 to 100%, I will pull roughly 450 watts from the wall. Your build would use just over half of that with the 780. (And bear in mind that its rare to have the CPU and GPU pegged at 100%).

 

This here will suit your needs just fine: https://www.newegg.com/Product/Product.aspx?Item=N82E16817139144

 

If you want to save money, this refurb of that same model will also be just fine. I have this same refurb in my secondary build and its been great: https://www.newegg.com/Product/Product.aspx?Item=N82E16817139124

That's a RM, not a RMx. Completely different PSU.

RMX is the replacement for RM. RMX is a nicer unit, but you can't go wrong with either. They certainly are not "completely different".

They are completely different. Sharing nearly the same name does not mean it's just slightly updated. 

You can definitely go wrong with an outdated $73 refurbished PSU.

Yes, the RMx replaced the RM, but they are completely different.

 

The TXM replaced the CSM, but they are the same platform, just the TXM has been updated and improved.

Feel free to enlighten us on how they are completely different. It's neither here nor there, but you seem determined so at least fill us in. I'm also curious as to what constitutes outdated in a power supply. My HX850 released at the same time as the refurb RM and its still superior to almost all of Corsair's other lineups. Also, as the owner of that reburb RM, I will vouch for it. I pull upwards of 400 watts from it (mainly from the R9 290x) and it has been flawless for some time now.

From a quick look at their internals, you can see that they're completely different from each other.

RM550

Spoiler

RM550x

https://www.tomshardware.com/reviews/corsair-rm550x-power-supply,4484-3.html

Spoiler

And all around they use different parts. Including Capxon capacitors on the RM, which are not present on the RMx. 

The RM650 is pretty much the same as the RM550. 

http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story5&reid=363

 

For hold up time, the RM650 is below spec, at 12,8ms, the RM650x is well within spec, at 24,3ms. 

 

And the RMx performs better in terms of regulation and ripple. 

+ The 10 year Vs 5 year warranty and the 50°C instead of 40°C temperature rating.

Looking at all of that, it's obviously completely different.

 

This is all basic stuff that anyone can find, just pointing it out. 

 

Higher end PSUs stay relevant for longer than lower end ones. And the HX also not the same as the RM.

Also, there have been 3 HX850 PSUs. One that came out in 2009, one in 2012 and one in 2017. 

 

Being able to load a 550W PSU with a 400W load is not impressive.

And if the secondary capacitors are blown, it could be sending very high ripple to your components, and you wouldn't know, unless you brought out an oscilloscope. Not saying that it has happened, just that you wouldn't know if it had happened. 

 

For $70, you can get the RM550x 2018 or the Focus Plus Gold 550W. Both of which have 10 year warranties, 50°C temperature ratings and perform better for regulation and ripple.

Try the seasonic evo 620. Its modular as well.

The M12 II? Sure, If OP wants an ancient, group regulated and loud PSU that has issues with its protections.

No, the s12

Same thing, just not modular.

Just wondering, but with 550W in mind, how about a EVGA Supernova 550 G2? there's one local listed for $85 but seller would do $60: https://www.kijiji.ca/v-computer-components/kitchener-waterloo/pc-power-supply%3A-evga-supernova-550-g2-550w-fully-modular-gold/1381385121?

Looking at this: http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story6&reid=440

I think that 550G2 that I could get for $60 is the winner of the bunch, correct?

Everything you mentioned is the result of an incremental upgrade. I have already mentioned that the RMX is higher quality, but the RM is also good unit. You didn't explain what makes a power supply outdated. Are newer power supplies more efficient? Sure. Do old power supplies deliver power to your PC. Yep.

 

Also, I don't know if you realized, but I have already linked the RM550x in this thread... it's not $70... its $100 on sale...

The RMx uses LLC resonant conversion on the primary side,  this means it has a much flatter efficiency curve and it handles transient loads *far* better... The even newer RMx 2018 then moves to a mostly wireless seeing (specifically removing most/all wires to the modular board).  The closest thing to the older RM in Corsairs current lineup is probably the CXm...

Wrong!

That's the RM:

that's the (older) RMx:

Absolutely different...

Urgh, not again.

We had that discussion a minute or two ago. Don't ya read what others are writing here?!

 

Its utter garbage, fan RPM of 2000rpm at medium load, garbage protection due to shitty HY-510N Protection Chip, no OCP on minor rails, no UVP on +12V Rails.

Why would you recommend such garbage?!

Oh wait, its Seasonic, so it must be awesome, because its Seasonic!1111

Sorry dude, but that's not how it works, as everyone has to use the same components and put together a PSU with the same parts...

There is no magic sauce!

Its a used one...

Wich means you get 3 Years Warranty at most:

https://www.evga.com/warranty/power-supplies/

Fan curve is on the agressive side...

 

Is it really worth sacrificing more than half of the Warranty for 20 Bucks or so?!

 

I do not thing so...

 

As for the Price:

That one is OK too:

You really don't need anything super beefy.

Something like a Corsair CX550M, or if you really want to, something like a Seasonic Focus Plus 550 would work just fine.

[Lord Letto]

Alright, if things go well I should be able to order a PSU this week or next week at the latest. for online orders, I've narrowed it down to 2 that's currently on Amazon warehouse deals: 

Corsair TX550M for $72.54 (used-good, repackaged, less than 5% cosmetic damage on the front)

Corsair CX750M for $73.55 ( 2 available for the price, 1 is used-very good, original but damaged packageing, less than 5% cosmetic damage on front, top & sides, accessories may have cosmetic damage, the other is basicly the same but without the top & accessories being listed)

Other Possible options if worth the extra $ for wattage is the 650 & 750W TXM with the TX650M being the most expensive at $82.62 (used-very good, original packageing, less than 5% cosmetic damage on front, top & sides) or the TX750M for $79.04 (used-very good, original packageing, less than 5% cosmetic damage on front, top & sides, accessories may have cosmetic damage)

for local options, it's either what I posted above from Kijiji or if Canada Computers got something in my price range as I could easily go to the Waterloo store.
