The V series fully modular is Seasonic. The V series semi-modular is Enhance. He didn't specify. The Enhance made semi-modular units are also very good.
 
Hey guys planning to buy a new power supply soon for my skylake rig. not planning on future sli. my options are Corsair Rmx550/650, Seasonic X 750W, and EVGA G2 SuperNova 750W. Dont really know much about power supplies. all these psu's are in my price range.

Thanks in advance
 


You're best off making a thread in the components forum for this. 😉 As well as including your full specs in that thread.
 
Be quiet! System power is basically the bottom tier of the Be quiet! brand. They are good, but nothing special. It's all right for a mediocre build, energy efficient etc with a single gpu, your average Joe gamer, but if you are something more than that, you'd be better looking at the Pure Power 9 or Dark Rock Pro 11
 
Interesting: Pure Power 9 actually performs worse than System Power 8, because not only is it group regulated, but also based on a butchered FSP Raider platform - the voltage regulation is so loose that it slides far out of the ATX spec. They were destroyed (figuratively) in reviews, so that's why Be Quiet is already prototyping the Pure Power 10 series (I've seen that myself)

System Power 8 in fact uses a Nippon Chemi-Con KZE capacitor on +5VSB, which is often overlooked in other power supplies - the +5VSB circuit is active all the time unless you unplug the PSU or flip its switch, so the capacitor that filters it is one of the first things to go bad - other than the fan and the main rail capacitors. I don't know what fan bearing it uses.

(You meant to write "Dark Power Pro 11", not Dark Rock Pro 11)
 
to Karadjgne: I suppose I'm using a "Joe build".

Hell, if I had money I would be looking at something modular with gold efficiency at least, but sorry, I'm a student, that's what I can afford after upgrading the vga (and I didn't spend billions there either).


I'm now looking at an evga 500w 80+ white model. I think I'll buy one of the 2 (this one or the be quiet 500w).

I'm open to suggestions, but since I have a limit of 60 euros, fees and transport included, there's not much better to choose out there, and it always gets messy bc of the price variations from country to country.
 


Review is from 2014...... And is one of the reasons that's become the number one budget unit recommended on the forums for the last couple of years. So it's not really a heads up. :lol:
 


oh....xP
 
Delta, FSP, Seasonic, etc... are OEMs. Manufacturers will take the board, and build a power supply around it and package it. Not all PSUs based on the same OEM model are the same. EVGA may use a different fan, cables, and chasis than Antec using the same OEM model, even though both are the same Seasonic.

So electrical quality should be identical between brands using the same OEM base PSU. The the end package, cables, and cooling will be different. Some companies have really nice cooling and high end very reliable and quiet fans. Others just slap a quick PSU together and sell it cheap.

 
Backwards. Seasonic builds the unit according to Evga specs. Slaps the Evga stickers on the side. Some things are taken for granted. When Seasonic tells Evga you need X size wire or Y size capacitor Evga engineers usually cave or up the ante. You won't, for instance, find a Seasonic 650w unit with 22ga wiring. Seasonic just won't build the unit. Standards of quality.
 
All I said was for $26 it's a great deal. I wasn't "suggesting" the PSU for anybody in particular here,

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?

1) Not within the warranty period. It's been >1 year. Why is it asked?

2) Xeon overclocking on a prebuilt rig...? In any case, I haven't bought either yet. I know for a fact that 450W for a Xeon and GTX 970 is already tight, not to mention an Intel 8260 and a Quadro K620. So I kinda had reserves about this. But, you know, it doesn't hurt confirming.

3) The 970's only going to be used in MDA... The K620 would be used to take advantage of acceleration while the GTX 970 is compute.
 
1| Usually when prebuilts get any form of modification, it's warranty is voided automatically which is similar to jumping off a building in spite of having a perfect life...no offence to anyone! :) Confirming it prior to any tinkering makes the end users life and the adviser's task easier.

2| There are some I've read on the interwebs with multiple fruition's. I used to fold at home and the more horsepower you had the more faster a structure was formed. I'd ask you to look through this thread/article since your on a workstation GPU and a gaming grade GPU, performance wise I'd ask you to stick on either one but the K620 is based off an older platform.

3| As #2 has stated keep one and ditch the other as multiple GPU's can often lead to less productivity(not to mention the extra requirements from your system). At least I stick with the single most powerful GPU's I can afford - I also do rendering work on Skp and AutoCAD.
 
I completely disagree with the cx series as a tier 4, i have been using a cx 750m for 3 years on my "high end" gaming system, gtx 1080 g1 gaming, full custom loop, and a 6700k oced to 4.8 and ram oced to 3.2. and i had no troubles playing intense games like the witcher 3, batman and other, i believe that the cx series should be ranked as a 3rd tier series instead of a 4th. im not trying to be a fanboy, im just disagreeing with my experiences as for the 130$ pricetag on a 750 watt psu with bronze and semi modular, i belive you are paying that extra for something sturdy and durable
 


Your experience consists of simply you and the PSU are using. If we ranked PSUs like that, you know how many problems we would have? Somebody can come on here and say their Seasonic Platinum failed after 1 year so it should be tier 4. Should we also do that? Any PSU can last long and fail early.

When you are gaming, your system should be using about 300W. The CPU itself is not going to be fully utilized in games, so the overclock you have on that CPU probably won't exemplify its increased power within gaming scenarios. In addition, how long a PSU lasts depends on your ambient temperatures, your positioning of it in your computer, how often you use it, and even if it's on 115V or 230V since 230V is more efficient and has less waste heat. You'll see a unit like the Cougar LX500/600 have a 5 year warranty in Europe but not in the U.S. because of that, where it is 3 instead.

Also, I don't think you had a GTX 1080 in your system for 3 years.
 
The issue, Andy, is you are dealing with a sample size of one. Believe it or not, I ran a "gaming" PC many years ago (AMD 3200+ with a 9250, upgrading over time to an AMD 3800+ X2 with a 7600GT) that used a "500W" Apevia Turbolink PSU-shaped object, and worked flawlessly. I got lucky with that tier-5 sparkler, but that doesn't mean it should be on tier-4 or tier-3. The teardown of the Corsair CX shows problematic capacitors that do not last under typical conditions, and less than stellar test results. It's entirely possible that yours is better than average, and/or your operating environment is better than average, such that you've had excellent results, however an overall analysis places it on tier-4.
 


Where are these tests though? Jonnygurus review of the CX units has always been good.

I have also used a load of CX PSUs with no issues. My current CX750m has been totally fine for years, my CPU has always been overclocked and I have had overclocked 680/780/1060 gpus.

They are miles better than tier 5 units that can blow up your computer.
