Buying Advice needed for PSU - Corsair RMx or Super Flower Leadex VII

[The N]

I narrowed down TWO good PSUs that offers good quality component and best fit in my budget.

1. Corsair RM850X (2024) ATX 3.1 @ $137.90 (01 year warranty)
2. Super Flower Leadex VII Platinum Pro 850W ATX 3.1 @ $141.87 (03 years warranty)

Since price difference is not much noticeable, I am looking for long lasting, and high quality components.

In our region, the warranty coverage ain't that great. A few things to note

• Corsair official distributor offer 01 year shop warranty, but Corsair is here for over a decade now and claiming brand warranty is not a present issue (stated by shop owner)
• SuperFlower, on the other hand, is pretty much NEW in our markets, in fact, they entered just 8 months ago. Not many have experienced SF product hence getting vouch is almost none.

As per my GPU and future upgrades. I am sure 5080/5090/4090 would not be possible for me at least in next 2-3 years. Currenty, I have 3060Ti but I have planned to upgrade GPU to at least 4070 Super or 4070 Ti/super in a couple of months. Depending on my budget on that day. CPU is i5 12600K but might upgrade to 7800X3D in a year or two. So I guess 850W would be enough for my requirement.

I heard Super Flower is a one of the best PSU manufacturer and remained OEM for EVGA in the past. But never had a chance to experienced EVGA (Superflower OEM) unit. Also, lots of positive thing about RMx series too, but again never had one.

Please advice. Thank you

If you're seriously considering a 5090 you should be looking at the 1000w-1200w models.

Both are very good power supplies if that corsair is the latest model it comes with a native 12VHPWR socket vs 2x 8 pin to 12VHPWR cable on the SF. Personally I would lean towards the corsair unit but both would be fine I just wouldn't pair a 5090 with an 850w unit a 1000w should be the min with a 1200w ideal for a bit of headroom.

5080 would be fine and 4090 would be fine stock.

Both units would be fine for upto a 5080 but if you are thinking of upgrading to a 5080 in a couple years time but looking at 4000 series in a couple months time then surely it would be better to actually wait a bit more to buy a 5080 + PSU at the same time.
The price difference between a RTX 4000 series to a 5000 series can't be that big if you are looking at buying new?
If sticking with upto 5080 range though and you are still looking at gaming at 1440p then maybe consider a 5070ti or even a AMD 9070XT instead,?
The gains between them isn't worth 100-300 increase in value.

If you are considering a 5090 then definitely look at 1000w+ PSU and get them at the same time.
There is no point upgrading PSU if there is nothing wrong with your existing one in my opinion, get the PSU with other parts you are looking to upgrade with.

Considering 5090 in out of question here since the market is too expensive in our country, and it's getting worse day-by-day. Could go close to 4070 Ti super or 5070 Ti.

Consair RM850X has dedicated 12V-2x6 socket with Type 4 cable
Super flower Leadex VII Pro 850w is 2x8 pin to 12VHPWR or 12V-2x6. Not sure, if it is 12VHPWR or 12-2x6. But PSU is same as the HWBusters has reviewed Leadex VII Platinum Pro

 

[Kwadratowicz]

Here is review of this corsair from HW busters https://hwbusters.com/psus/corsair-rm850x-atx-v3-1-psu-review/
So You can compare reviews from the same source and the how it works .

I will consider slight used card from 4000 to save some bucks. Might want to get ultra wide 3440x1440 resolution too. Secondly, not have experienced AMD cards specifically in video editing. Read online that AMD cards are not smooth in rendering some GPU effects in Adobe AE. i.e crashes or extra slows down the duration. Could be due to software optimization, but again not 100% sure.

As per 5090, I would not. Because even 4080 or 5070 Ti can serve my purpose very well. Secondly, it's sitting at conversion $4611 in our country, at the time of writing.

Fair enough,in this case I would wait and buy your PSU with a 5070ti is my vote.
But at the end of the day you do what is right for you.

Very likely that in January 2027 the RTX 6080 will be launched. Almost certainly it will have 24GB over a 256 bit bus, performance will be higher than 4090 either by a bit or perhaps halfway between 4090 and 5090, power draw no more than 5080. MSRP probably $1200 but hopefully $1000.
That means that upgrading to that you won't need more than a 1000W PSU. And even further into the future, you can have 80 class cards with relatively tame power draw.
So if you can afford it go with 1000W now and be carefree for the next years.

For 1000W I have two very good proposals, first should be cheaper, Super Flower Leadex VII 1000W XG (solid unit, check out the HWB review, I got one at Aris' advice), next more expensive but in my opinion it is the best 1000W package that you can get -> Corsair RM1000x v.2024 + 12VHPWR Type 4 cable (CP-8920284). Why spend extra on the cable? To avoid using the included cable which has 12VHPWR connector at both ends. 2x8 pin FTW!

Strictly from the two options in the mainpost, I would choose the Corsair given it's not more expensive, I also don't quite like the Leadex Platinum models, their reviews reveal some deficiencies, also those special 9 pin sockets on the PSU are of the "reinventing the wheel" variety, so in the end not top tier units.
However the warranty period aspect is not easy to ignore.

Regarding GPU, 5080 is bad value, for example I bought 5070 Ti and with the money saved I can buy a good UPS which is far more useful to me than the extra performance and the extra decoder of the 5080.
So if you can get 5070 Ti go for it, it's a pretty well rounded package with okay value.
Or 40 series, like 4080 Super but no more expensive than 5070 Ti again very solid option.

With 1000W, I'd get a little extra headroom especially considering future upgrade options. But then again, budget constraints. I wanted to save bucks. Let see if i can arrange some funds for 1000W.

12VHPWR? Doesn't RM1000x have 12V-2x6 native.



Secondly, XG unit from Super Flower is not available in our country as SuperFlower is not interested in marketing this unit here. SF began stocking PSUs with Platinum Pro PSU.

I understand. If you can stretch it would be ideal but if not RM850x is very good.

12VHPWR? Doesn't RM1000x have 12V-2x6 native.

Yes the socket on the PSU is the updated version, I was referring to the cable plug that's why I used the term "12VHPWR". Sorry for the confusion.

There is no problem with using the included cable that has the plug at both ends but with the Type 4 cable (2x8 pin) you would have what's probably the safest and sturdiest connection (at the PSU side) available today.

That's too bad, having less options. But you only need one good model that fits your needs to be available and at the right price.

I've been using a Corsair RM850x since 2019, and I've had zero issues with it. It's running quite a few components: 6 140mm argb fans, 280mm aio, Ryzen 9 5900x, RTX 4070 Ti Super, 3x SSDs, 1x HDD, two wireless controller chargers, rgb mouse pad, etc and the fan sits idle 90% of the time. I'm using the white one in my pc, but I recently bought a black RM750x for a pc I built for my daughter for Christmas, and so far so good. When the time comes for a new PSU, I'd definitely buy Corsair again...just my 2 cents.

 

[lambda]

Which ever has more support locally in terms of repair/RMA etc. Might be Corsair in this instance.

It;s actually a good suggestion, and not a big deal that extra $12 for peace of mind.

Just bought Corsair RM1000X ATX 3.1 along with Type 4 2x8pin to 12VHPWR cable.

May it serve you long and well.

I had a super flower blow up on me(though it was fairly old) so I wouldn't personally go with them(it was this one: Super Flower Aurora SF700R14A 700W ATX v2.2).

I think that is quite old. Aurora. Don't see this PSU on Super flower current website. So must be old product.

Yeah it is from like 2009 or so, but it's the only PSU I've ever had that blew up, and I've used many.

Sorry to hear. A bad experience with Super flower. But on a given day any unit can blow up if it is bad or voltage messed up, as this involves multiple factors.

That's fair, I've just never had it happen before in ~25 years in IT.

By blow up you mean?

@The N
i bought a SF around 2005 when i worked in a shop and the started selling them, lasted 6 month before killing my mb (caps iirc) when it was stressed (below max output),
and i switched to bequiet (dark power came out) just to avoid a possible mfc issue on the SF, but havent seen any review in the past 5-6y, that would not make me consider their units.

then again, i dont look at the "cheapest" offering of any brand, decent units tend not to be the cheapest.

Every brand has cheap/cheapest units available for low or budgetary segments, but also offers high-quality/top notch units. I haven't owned Super Flower PSU but what i read on multiple forums is that SF is a one of few PSU manufacturer that offers high quality PSUs.

For example, Currently, their Leadex VII XG series is exceptional having standard modular panel unlike the Platinum PRO which has something called Sky-high in-rush current + an entire 9 pin modular panel for all cable connectors which I haven't seen on any other brand. Althought in reviews there found nothing concerning at all as Aris at HWbuster recommends it too.

I actually leaned towards Super Flower PSU, due to it's high-reputation. Haven't used it before but wanted to experience it myself. But in the end, went with most recommded Corsair RMx unit.

@The N
my problem isnt with low cost models at all, just the fact that many arent worth buying, unless its going into some office rig without dgpu,
and i cant remember a single brand that didnt have a low end unit being a waste of money (to buy), and learned reputation of a brand or having (other) "good" units,
still doesnt guarantee another units quality, and why i rather spend a little more (than not).

Where are you located? Corsair covers the unit with a min of 2y, not just 1 (store/shop is irrelevant), EU and others have consumer laws requiring 3y.

Pakistan. It comes under Asia-Pacific region. Brand warranty is 10 years but Corsair is only providinig them 01 year warranty, as stated by authorized distributor.
