hah, so the easy option was the correct one. Use 2 cables lol. I just wanted to make sure that doing that was the "correct" way and you weren't supposed to use some dedicated cable that new "compatible" PSU's came with or something like that. Much appreciated in making sure that I was over thinking it lol. The RM1000x does come with 2 CPU cables so I'll be set for the future

Guys, so I have been saving up to buy an new RTX 3080 Ti/ 3080 (whichever is cheaper) & wanted to upgrade my PSU from a Gigabyte G750H to a 850w PSU as well to have enough power headroom.

I am having an Intel Core i7-8700K with MSI Z370-A Pro motherboard.

I was having a few PSU models in mind but I wanted to consult my choices with folks in this forum who have better knowledge than me about these. Below are my PSU choices:
Note: I would have gone for Seasonic Prime 850 but unfortunately they are not available in my region.

So I have heard good reviews about the NZXT C 750/850 series, so do you guys recommend it for my system?
Or else which PSU will be better among the above choices?

I have made a post in PSU thread but also posting it here as well as per @Eximo's recommendations. :)

There are 1kW Seasonic PRIME units out there too and if you'd go with 3080 Ti, 1kW PSU is more comfortable choice.

But from the ones you listed, Antec and NZXT are both made by Seasonic and it doesn't matter which one you'd pick, since they both use Focus platform.
Personally, i'd go with (if no Seasonic is really available), NZXT. I've dealt with NZXT customer service and they are very nice and friendly.
NZXT 850W review: https://www.tomshardware.com/reviews/nzxt-c-series-850w-power-supply-review

Though, on Corsair side, i'd go with AX or AXi. RMx is also good but my personal preference outweighs the price in favor of quality. And AX/AXi are top-of-the-line form Corsair (similar to Seasonic PRIME). AX is made by Seasonic (except AX1200 which is made by Flextronics) and AXi series is fully made by Flextronics.

With the latest flop of Gigabyte PxxxGM series, i'd avoid the brand completely, especially when it comes to PSUs.

I purchased a computer locally today that came with a Rosewill RG630-S12 PSU that claims to be 630w 80+ Bronze.

I can only find one review of it and it seemed to be decent back in the day, but is a rather old model. My particular unit appears to be relatively new as it has next to no dust versus the rest of the PC which is dusty.

Any thoughts on it today? Would it be enough for a GPU like a GTX960?
 
If Gabe Torres said it was a decent unit, then it was a decent unit. Or at least the one he tested was. Gabe was one of the top PSU reviewers back when he was doing reviews. IF the unit is in good condition then it should have no problem with that graphics card.
 
No idea on that one. That IS a problem, because Hardwaresecrets was one of the main PSU review sites for a long time, and back then usually if one primary site reviewed a unit then nobody else would review that unit. Losing so much information from Hardwaresecrets mostly being defunct now means the loss of a lot of the only reviews that existed for a lot of PSU models. But honestly, any unit from 2009-ish, is probably best to not be trusted with valued hardware anyhow if we're being honest.

Thanks. I'll have to check the insides later today, however I noticed the sticker on the review unit read 80+ and mine reads 80+ Bronze.

Given the review unit seemed to qualify for bronzs perhaps they went back and got it bronze certified?

Wow, a competent unit from chieftec.

Their units are actually quite good for the most part. Chieftronic (Chieftec's sub-brand) Powerplay is CWT GPU(750W)/CST(850/1050W), good stuff. Chieftec Core BBS is CWT GPS, decent budget unit. Chieftec Proton is rather meh but it's also very cheap in some markets. Not to mention a bunch of older units majority of which were okay, mostly made by CWT and High Power too. The only lemon i can think of is Chieftec Powerup, based on CWT GPX which doesn't fare very well under high-load and low input voltage (90/100VAC), at least on 750/850W versions.
 
Actually, while there are a large number of units made for them by CWT, I don't see that there are any from High power unless they are very recent. The majority seem to be CWT and Sirtec. And yes, they have some good units but they've also had some extremely poor quality ones as well. The majority of those unfavorable units are pretty old though, and practically all of the reviews of them are gone from the web now. Still, I quite clearly recall several Chieftec models that blew up in JG testing (Like the Chieftec 650) and many others that were unable to sustain anywhere near their rated capacity like the Nitro 550.

They also have had a ton of very mediocre units that lacked adequate cabling options, really poor quality fans or cables that were ridiculously short for the type of unit it was. And also, as you say, a number of units that were pretty bad under low load conditions. But they are definitely not the worst brand out there by a long shot.
 
That's fair.

I still think a 2 year warranty is completely unacceptable for a new unit >$35.

A 2 year warranty on every single unit in your lineup including $150 ones is a sad joke.

A lot of companies I see start out at 3 years, and something like a thermaltake smart 80+ white has a 5 year warranty
 
Yeah, the warranty alone would likely make me avoid them entirely when there are comparable or better units around the same price with much better warranties. There ARE some regions though where they are practically the only decent option and often many of those regions have similarly short or non-existent warranties on a lot of things, so might not actually be the worst choice for those people.
 
No, it isn't. They all have distinctly different platforms even though it might be the same parent company. That's like saying Sparkle and FSP are the same. Or saying Seasonic and RSY are the same. Or that Lab IX is the same as Flex (Flextronics). But yeah, I get your point, clearly, but still not the same really. Some platforms carried by any of those companies have observed similarities, but there are also distinct differences in platform design AND build quality, from one sub to the next. If there wasn't, none of the reviewers would ever bother to say the OEM was one or the other, they'd just say they were all High Power, and they don't do that, so.........

Those are all semantics, High Power is the retail brand of either Sirfa or Sirtec, i'm not sure which exactly since they've split up in 2008, High Power's site isn't very clear on what parent company they're operating under and i'm not in the mood to try to dig it out. Regardless, when i was saying 'High Power', i mean't the OEM behind it, i.e Sirfa or Sirtec. They may be not 'the same thing' in the literal sense but when we're talking about PSUs they are, because there's only one actual OEM behind these products. And i'm not sure what 'distinctly different platform designs' are you even talking about, there's a bunch of platforms by that OEM (whatever it be, Sirtec of Sirfa), they all have similar design decisions, markings on PCB and inductors are certain way for example, so you can just say that say, the OEM behind Chieftec Polaris, Chieftec A-80, Fractal Design ION+ and Thermaltake Grand RGB Gold is the same. Unless you are talking about, literally a different OEM, in which case i'm not aware of any which may be confused with or bear similarities with Sirfa/Sirtec's designs.
And speaking of RSY & Seasonic, these are indeed, very much separate and different companies, the former just manufactures a couple of units for the latter, so bad example.
Regardless, i get what you perhaps was trying to say, quality and performance may and will vary within a product stack of any OEM, or even with different units supposedly based on the same platform. So in that sense, judging the PSU quality just by it's OEM is completely pointless, unless it's literally garabage-level OEM based in the uncle Wang garage with no quality control or consistency.

Its really a shame that Amazon promotes products like this. Granted, Amazon wouldn't have known there was an issue without proper testing.

I have doubts about their claims that some of the units meet 80+ gold. I can't say for sure if they did or did not, but using double forward and having underwhelming component quality elsewhere, meeting 80+ gold would have been unlikely.
