PSU tier list 2.0

[Lutfij]

I run an older platform(AMS Build log) and the BE is overclocked beyond it's stock clocks so that is also out of the run for a pseudo good PSU which brings me back to what I said, before a unit is slapped as good it needs a prerequisite of what it'll be powering to qualify it as a good unit. PSU test and testers subject the unit for a set duration of time not for days or months on end.

The numbers, that I showed, were for GPU only. Mine is more power hungry than a reference 780ti, by a fair margin. Hence why I want a GTX 1070 so badly. Had it been total system draw, I would have agreed that it would have been safe.

The same can be argued about any units. Corsair AXi. How do we know they're really reliable if they're only reviewed for some hours rather than months? All we have to rely on is component analysis, and the CX450M has good components. They also wouldn't give it a 5 year warranty if they didn't expect it to last 5 years. Corsair will lose money if they have a ton of RMAs.

If you're going on about product failure before the warranty period then you should read into all the tech support threads on Tom's about failing motherboards. You might've also been around long enough to know the wide spread recall of the EVGA Supernova PSU's before it's warranty period until they decided that it needed a revision and an increment in their warranty to reimburse confidence in consumers.

You're yet going on about how good the CX450 is. We're saying it's not a good idea to put it under an umbrella. You of all those experienced would know that you look into the system's specs and ofc its usage/work loads before suggesting a PSU to begin with - the GTX780Ti of all this discussions.

How do we know they're reliable? Well, by following through reviews(not just one reviewer). There are even threads dedicated to some popular units on OCN.

So in a nutshell:
Corsair CX450M(the new one)- A good psu, perhaps. A good PSU for an overclocked(modern) system, depends on the components and the clocks.

I'm going to jump the gun if 450W can power 8 thread Xeon, a GTX 970, and a Quadro K620. Does it?

 

[Karadjgne]

Well if you look at the MSI nightblade MI2, they are dropping a gtx970 with a skylake cpu on a 350w bronze psu. So....

All I said was for $26 it's a great deal. I wasn't "suggesting" the PSU for anybody in particular here, I was saying, "hey guys! If you want this PSU better get it fast while it's dirt cheap!"

The Quadro seems to have a TDP of 41W. A normal GTX 970 is very efficient, but overclocked models go around 180W. 221W there. Those Xeons should be pretty efficient. I'd say under full throttle you're looking at 300W. When gaming the Quadro won't be used, so that should be more like 250W maybe, probably less actually since the Xeon's 8 cores won't all be utilized. More like 225W. Of course the exact Xeon matters, as well as if the GPU is overclocked at all, or what aftermarket one it is. but my numbers should be close.

The CX450M has two 8-pin PCIe cables so would work perfectly!

Have you actually SEEN one with a 970 AND a 350w psu? I see that it says "up to a GTX970" but I would think a 970 would come with a "free upgrade" to a larger unit.

 

[turkey3_scratch]

If it's the reference 970 with a locked modern day Intel CPU a 350W PSU seems perfect to me, if it's good, that is. I just wish there were more of those but obviously MSI isn't going to install a non-working PSU with their hardware.

 

[Turb0Yoda]

Watch it say in fine print somewhere "underclocked by 400 mHz" or something like that.

 

[Lutfij]

The concept with pretty much all prebuilts except for those that are top tier will expire at or near warranty expiration and eventually you're going to have to rely on them to get a replacement part since the PSU is proprietary as per their documentation/product brief. The unit used looks like a flex atx unit but I'm not going to base any suggestions for that barebone because it comes in at a very lucrative price point, one where you're going to ask yourself, where did they cut corners? Wanna bet they did it with the PSU?

Long term use in that cramped environment, I'm not so sure how that will fair. I'm actively involved in Compact Splash's projects and you could run a GTX780 HOF off of the ST45SF-G but the fan ramps up too high to cool it's components and the long term answer to that is don't keep it at that state.

Turkey,

It's useful for a modern day system with a single GPU, even with overclocking.

A lot of forum goers look up to this thread for advice on their builds thus the concern that they will need a little more disclosure.

okcnaline,
You may want to reconsider your route of using that Quadro as a Physx card or in tandem with a gaming card. It'd be better to use either one of them and leave it at that. When only on the GTX970 I'd say you're good with a 450W psu but then what unit you're going to use comes to question. Remember when choosing a PSU you'd need to also consider the headroom available in case you'd like to overclock or keep the unit for a longer duration or both. Since you're on a prebuilt Lenovo machine are you within warranty period?

If a forum user has a machine that the CX450M can't handle, sees my comment on the last page of this forum thread, then unknowingly buys the CX450M even though it can't handle his machine, that is his fault for not asking any questions or doing his own research beforehand. I still don't see how me saying the CX450M for $26 is a great deal has anything to do with this!

 

[turkey3_scratch]

So I'm curious, have any of you owned a CWT power supply? I hear they always smell really gross because of the factory and the smokers in it. Is it true?

 

[Deleted member 217926]

I've been more than incidentally keeping up with computer power supplies for more than 15 years and I've never heard that. I had a first gen TX750 for 7 of those years.

 

[CTurbo]

Yes I've used some CWT made Antecs and I've never noticed a fowl smell, or heard that rumor.

 

[Karadjgne]

Turkey, stick to glue. If you are thinking of sniffing the odd psu just in case, well that's just.... unnatural

 

[Lutfij]

Sigh.

I've worked on multiple builds with Coolermaster G + Thermaltake units and they smell like any brand new boxed component. I wonder what your source of info is?

Now that's funny. I think perhaps Turkey had his tongue-in-beak though on that remark, since this commentary on the CX-450M is wandering into conjecture and rumor.
Imho, a CX-450M "ought" to be able to power a stock Haswell or Skylake CPU and a GTX970 that doesn't need more than a single 8-pin PCIe power cable (e.g. Asus Strix), which would would mean 225W (with potentially higher brief spikes as reviews have shown). Such a system under a gaming load is probably going to pull 300W-350W, which a 450W PSU should be able to handle long term.

[kavorg]

Can someone tell me if Antec TP-650s or 750s are as good as True Power Classic ones, or in general are they good PSUs?

 

[turkey3_scratch]

Most GTX 970s I see seem to be an 8-pin and a 6-pin; which seems kind of silly to me. But the CX450M has two 8-pins anyway.

 

[logainofhades]

My previous PSU was a TX 750, and I have an HX 650, for a backup unit.

 

[Onus]

My Asus Strix GTX970 has only a single 8-pin. I think my HD7970 had an 8-pin and a 6-pin, and my HD7870 has a pair of 6-pin. I've been mostly successful in cutting down the power I need, such that a good 450W PSU should be sufficient.

 

[Ravi_Singh1900]

Cooler master V series is better than Antec Edge I cant digest that. I think Antec Edge should be there in tier 1.

Coolermaster V series is a Seasonic X platform. The Antec Edge is a Seasonic G platform.

I thought the V550 was Enhance?
