I see several references to 80 Plus Titanium and superflower has a consumer model.

it is clear it is only for 230v common in europe.

what is unclear is if there's an 80 Plus Titanium for 115v used in the USA

adds a new category 10%

based on this
http://www.maximumpc.com/article/news/c ... m_spec2013

Cooler Master's V Series PSUs Ready for Upcoming 80 Plus Titanium Spec


according to this article there is no standard yet for 115v USA BUT Coolermaster has a model that meets the specs.
Quote:

Not satisfied with current 80 Plus standards, Cooler Master claims its V Series is prepped and primed for an 80 Plus Titanium tag, as soon as it officially exists, that is.

Cooler Master says its V Series PSUs use the highest grade Japanese electrolyte and solid capacitors, high quality 42mm transformers, and a custom interface PCB that aligns all rails to reduce voltage plane cross-over and minimize crosstalk, EMI, and droop.

No word yet no price or availability.



w/Titanium and 10% that makes fanless all the more practical

80+ Titanium is only for server PSUs at this moment which are rated to work on 230V, even in the US. There is no such thing as 80+ Titanium for consumer PSUs at this time and is neither available in 230V areas or 115V areas.

Coolermaster are just being speculative. Other PSU makers probably also have something which might pass but without the specs published, who can tell?

80+ Titanium is slowly coming to the consumer market.
While trying to find some consumer 80+ Titanium PSU's i came across this..
http://superuser.com/questions/357495/why-would-80plus-not-certify-any-115v-power-supply-as-titanium
Quote:
I^2*R losses (in the wiring) scale with the square of the voltage. Half the voltage means four times the I^2*R losses. Typical home wiring resistance might be .5 ohms.

So, let's take a 450W power supply that's 90% efficient. It draws 500W. At 115V, that's 4.3478A while at 220V, that's 2.2727A. So the I^2*R loss is 2.58W at 220V but 9.45W at 110V. The difference, 7W, represents an extra 1.5% of effective power supply efficiency.

Since Titanium is targeting 96% efficiency, you can't just ignore the 1.5% loss. That's 1/3 extra loss.

Now i cant pretend to understand the mathematics involved :oops: but i hope it answers the 230v versus 115v question.

Hm,
looks they aimed at Titanium and all they got was Gold :(

http://www.coolermaster.com/product/Detail/powersupply/v-series-psu/v700.html

Fully modular cable design incorporates a single 1000W +12V output that delivers up to 58A.
80 PLUS Gold certified: up to 93% efficiency @ 50% load
Silent 135 mm FDB fan for lower noise and longer lifespan
Four PCI-E 6+2 pin connectors to support high-end GPUs
100% high quality Japanese capacitor ensures performance and reliability.
Reliable 5 year warranty

Specs: Model RS-700-AFBA-G1

Its not bad but not Titanium or even Platinum (which does exist at consumer level)...

And what's worse - It's far from the claimed 90%+ at 10% load (at least for the 115V model); its not even certified to the 93% they claim?
