What PSUs do you buy??....

[cst1992]

I keep wondering, why do people need such large power supplies?

SLI is dead - I'm sure Crossfire isn't much better.

Your CPU will consume 200, 250 watts max. Your 3090 - 400? 450?

That's 700. Let's keep another 50 for other things. Why need anything higher than that? 850? 1000? 1250? 1600?

Running the Cooler Master MWE550 80+ for nearly 2 years now, still running great.

Because the price difference is not much, specially as second hand.
Also I want the fans to remain in zero-mode, so power consumption must be much lower than total capacity.

If you get a 850psu to consume 700watts, it will be hot and noisy.

No, it won't be. If you've got a bad fan, sure. But otherwise it won't be very hot.

"Future proof, BROOO"

To do what? Don't tell me you run your Christmas lights off of your PSU. Or does it have an extension to plug in your soldering station?

All other things I've already accounted for. If you want to run 400W CPUs and 600W GPUs off of it then I don't know what to tell you.

 

[Lei]

The price is so crazy close. btw a higher capacity is probably used less than a lower one.

No, it won't be. If you've got a bad fan, sure. But otherwise it won't be very hot.

It has ten years warrantee. So future-proof that my soul will return to hunt the psu.

[cst1992]

PSUs are designed to run 24/7 at the rated capacity for years on end - because that's what they do in servers. I accept that consumer-grade PSUs won't be installed in servers, but the point is you could run your PC constantly on it for 5 years and it'd be fine.
A higher capacity is used less - because people think they need more capacity than they actually do. I could run my system with a 4690k and a 3060Ti on a PSU that's rated for 450 watts, but still I've got a 650W PSU. It's not for "futureproofing" - I don't really have anything more that I could put in it that'll put any significant burden on it.

Seasonic Prime TX/Corsair SFX Plat.

Don't ever skimp on PSU. Not only is it dangerous, it's braindead, as a top tier model will last 10 years plus and from build to build.

 

[cst1992]

Most people don't intentionally skimp on their PSUs but simply buy prebuilts that put in the absolute cheapest, shittiest units they can find.
Naturally, such PSUs don't last very long. Well, that's additional service money for the prebuilts...

That's why I prefer a second hand Corsair to a mediocre brand new one.

And prebuilt has no place in my universe.

 

[dirtyferret]

I have no brand/make loyalty just price-performance loyalty.

 

[bencrutz]

you pretty much said what i was saying. - If you dont get it, i dont know how else to spell it out for you

i'm just confused on your statement

there's no AXi using seasonic

 

[AlwaysHope]

No option for Silverstone?
I have used those for yrs already & daily use too. No problems with them at all.
Apart from that I also have Corsair unit on my main gaming rig atm & a 2012 AX760 still in daily use on another rig.

 

[R-T-B]

perhaps none at present.

Titanium units still are pretty sure.

 

[Samiam66]

Corsair PSU & AIO ...Ditto

What PSUs do you buy??....

i go for whats good value built nice and a good long warranty, seasonic gx range with10y warranty fits the bill right now ive a gx750 and gx850 i like the focus range but i like corsairs RMs ive a RM850i its about 5 years old and still going strong "touch wood" and theres still a bit of warranty...

Have you not seen the rumours for the new RTX 4 series?? 700w cards?? POWER!!

Thanks for all the replies guys I'll hopefully grab a few Seasonic units I think, will see if I can step up to the Prime/PX models if I can find them at a decent enough price and by that I mean, something like £30 different to the GX models I believe they are? I'll have a look into it anyways

I've got some 3070s/3080s/3090s so I'll be needing something that's going to work and last well. Plus a few X58 rigs and such that are needing a little more juice than normal anyways Thank god for solar panels, is all I can say!

 

[cst1992]

Well, I guess what it'll take is someone's house burning down...

 

[dirtyferret]

I noticed which is why I think I went over to Seasonic, I've not really had that many issues with either

I've had more issues with seasonic than other OEMs but I've also owned more of their built units (I mostly stick to seasonic & Channel Well).

I really only grab A Tier PSUs

What is a tier A PSU?

 

[freeagent]

I have a 750w psu and have seen closer to 650 usage at the wall. I would have gotten an 850 but at the time they were really tough to find. 12 year warranty so hopefully she won’t let me down.

What is a tier A PSU?

I think JonnyGURU used to publish a PSU tier list that ranked the common models.
I don't remember if the tiers were called A, B, C though.

Also, LTT publishes such a list - mirrored on Tom's Hardware.

 

[seth1911]

Superflower and for cheaper or special things like FLEX ATX its FSP

But where is Silverstone?, they have good SFX PSU and a EPIC SFX Passive PSU

Spec'ing a PSU "Just for" the total wattage of the system isn't really a good idea.

Some headroom for power/load spikes should be taken into consideraton so if that happens the unit will handle it no prob. It's also easier on the unit if it's not already running at 100% capacity all the time which is not a good idea, the nominal load value of a PSU is around 80% of it's rated wattage continuous. Yes, I know units are designed to go over this spec'ed value at times but then again it's not good for it to see it bumping the ceiling all the time either.

This kind of strain will take it's toll over time, just how it is and by making things a little easier on the unit in use helps to ensure it living a long, happy life if it's going to at all.
It's better for the system itself too, doesn't make sense to risk subjecting it to a simulated "Brown Out" condition over and over again because it's starving for power and we know what brown outs can do to electronics and electrical stuff in general.

Using your example of 700W if you were to then add 20% of that value you'd come up with 140W making an 850W the ideal unit to go for. Not much difference in the cost vs the potential benefits of doing it this way.

Running the Cooler Master MWE550 80+ for nearly 2 years now, still running great.


"Future proof, BROOO"

Well.... That's actually true to a point.
For the reasons I gave above is part of "Why" it's not a bad idea to get one a little larger than the total expected load of the system.

As for "Future Proof" the ones I've got, being 1600W units can handle those 700W RTX 4 series cards right now without issue and I bought these PSU's at least 5 years ago - So there you go.

If I were to get one of those, no need to go out and spend even more $$ for a replacement PSU on top of the cost of the card too when what I already have can handle the power demand for it.
That's just good value for the $$ I spent back then which, BTW was less than a equivalent PSU unit for such today.

I don't remember if the tiers were called A, B, C though.

Jon made a list (the site did not) but never openly published it as it became too much work and the tiers went from five or six to close to ten and he was realizing he probably needed even more tiers.

Have a look online, any search with PSU tier should give you a good result When and if I can when I get home, I'll put up a link but I'm sure you'll be able to find the same or something similar
