M12II EVO is a new model, but it's almost the same as the old version, just fully modular. And 620W version and below is just old group regulated S12II / M12II platform.

CWT is fine. RM650 is built with worse, less reliable parts than VX550. Also, it runs the fan at a much lower speed or even completely off for a lot of the time, meaning less heat evacuated so more stress on the components. It's okay, but there is often better. That said, the design is much better than old VX550, so higher efficiency, lower ripple, etc. offset the lower quality parts and lower airflow. If you are fine with paying a little extra and having lower internals quality, RM should be an okay choice.


You are overlooking 12 cm fan models with slower fan speed control. See some above posts.

Check graphs here:
http://www.techpowerup.com/reviews/CoolerMaster/V550S/6.html

Look at the fan speed / rpm vs. load curve for 38-46C ambient. Then look at the one for 28-30C ambient (more realistic).

Corsair VX has an ADDA 2BB 12cm fan not much different than the Yate Loon 2BB 12cm fan in the Cooler Master. At testing of 22-25C ambient temperatures, see fan speed vs. load curve:
http://www.xbitlabs.com/articles/cases/display/corsair-psu-roundup_5.html

For example, from the graphs you can see the V650S (if it has the exact curve vs. wattage as the V550S does; it might be better) should run the fan under 1000 rpm under 350W or so with normal sub-30C ambient. Quite possibly it could be less. Under those conditions, at 350W, V550X was seen to run the fan at 2000 rpm.


So you would need to spend much more than 100 euros to get something very quiet when running two graphics cards, but for your current setup, VS and many others... Seasonic G too, etc. should be much quieter than what you have now.

Of the new options listed, Enermax Revolution 87+ has a better fan, also low fan speeds up until 50% load, better build quality. But worse performance and higher cost.

Thank you, but it is too expensive for me.

thank you very much mikeaj!

Has the Enermax Revolution 87+ worse performance that CM V650S?? I always thought it was a manufacturer Enermax quality.
I'm afraid the Yate Loon D12BH-12 is noisy. Remind you that fan is 2300rpm and 41dB. http://www.yateloon.com/style/content/CN-02c/product_detail.asp?lang=2&customer_id=1356&name_id=31277&rid=58938&id=38837
Enhance Electronics Is a good OEM? The CM V650S has only two 8 PCIe connectors. If I put another graphics card in the future I will have to put Molex to PCIe adapters.
The CM v650 price is 94 €, while the Corsair RM650 is 101 €. The difference is small. It is within my budget.
What do you think about Enermax Triathlor FC 80 650 (106€), Enermax Revolution X't 630W (109€) and Enermax Revolution X't 730W (115€)?? In theory these fans are better and quieter.
I don't want to have coil whine.

So you think the best and quietest PSU is V650S? Is not worth buying the Enermax Revolution 87 + for the price of 117 €?

Sorry for my English frown.gif

No the Enermax Revolution 87 has really crappy ripple so dont buy that one

Cooler Master VS is still the best unit

Enermax was never really a great value. Revolution X't is manufactured by CWT, but who really cares? I guess on average Enermax's manufacturing quality is better than most others, including the average CWT-manufactured power supply they sell under their own label, but the designs recently aren't really that good. That model is not very good for the price. Same for Revolution 87+ and Triathlor FC. Some of these do use quieter or better fans, but you actually may get more noise out of them because of the fan speed control curve.

Of course Yate Loon D12BH-12 is loud at top speed. That's why I posted all those links and explanations showing that the actual fan speed used is much lower and by how much. The fan speed is temperature controlled and you won't be seeing 2300 rpm ever unless something is broken.


I agree that the connectors on V650S is disappointing. It's like Corsair used to be... 2 PCIe on 650W? Why? Some product manager needs a wake-up call. Either deal with that and use adapters or pay extra for a little worse quality but full modularity and 4 PCIe connectors in the RM650.

Or another option is saving money with Cooler Master G650M, which has 4 PCIe connectors, though all of them are hardwired. Build quality is closer to Corsair RM though. Efficiency is a little worse but actually pretty comparable at lower loads.

aha, But the G650M has less quality and efficiency is bronze.
I add this PSU: Be Quiet! Straight Power® E9 580W CM price: 110€ Slight power? Perhaps?
post #27 of 62
Efficiency is rated bronze on CM GM but actual efficiency is better than most silver units except at high loads. See here:
http://www.plugloadsolutions.com/psu_reports/COOLER%20MASTER_RS-650-AMAA-B1_650W_ECOS%203674_Report.pdf
Also TechPowerUp's numbers for the 550W on 230V:
http://www.techpowerup.com/reviews/CoolerMaster/G550M/5.html

When I saw the price on the E9 CM, I knew not to mention it. Fan is good and is run at lower speeds, but the quality is no better than Corsair RM. You would get a lower wattage and higher price on it, so no.

If you have a good experience with Corsair and especially if you don't plan on actually using your computer for heavy calculations 24/7 and are turned off by Cooler Master VS's cables and GM's quality / efficiency and everything else, the original RM650 choice is not bad here. Is their warranty service good in your region?

More PSUs availables:
  • ENERMAX REVOLUTION 87+ 650W (117€ a bit expensive than other ones and it has 4 12v's rails.)
  • Cooler Master V650S (120mm fan, probably noisier than other ones PSUs, OEM is Enhance Electronics, two 8 PCIe pin)
  • Super Flower Golden Green HX 80 Plus Gold 650W (I know it is a good power supply, but it is not modular and has a 120mm fan (noisy?)
  • LEPA G650-MAS
  • Thermaltake Paris 650W
  • FSP AURUM 650 80+ ORO MODULAR (113€, 120mm fan, probably noisier than other ones PSUs and it has 4 12v's rails.)
  • Enermax ETA650AWT-M Triathlor FC 80
  • Antec HCG- 620- M
  • Seasonic Serie G G-550 (only 550w and noisy(?))
Thanks!

Right, those are the shops, plus amazon.
That's a good power supply, but in my country is more expensive.

 

Again, you don't need anything 'bigger' than a good quality-made 450W PSU. So no, the SeaSonic G-550 will not be noisy.

Virtual +12V rails speaks about outdated PSU design. You should choose PSU with one "fat" +12V rail.

No, not quite. There are good modern PSUs that have more than one +12V rail.
