Ja popieram zasilacze z minimum 450 W aby miec mozliwosc na rozbudowe.
Sam uzywam 550W.
Warto miec rezerwe mocy na rozbudowe aby unikac jakich kolwiek
problemow.
Dlaczego?
Majac 5 Hard Disk Drives, 2 DVD CDRW, CD ROM, 1 GB RAm albo max,
kilka wentylatorow dwa monitory, experymentujac z PC potrzebuje duzo
mocy.
Wiekszy zasilacz ma zawsze o wiele lepsze i bardziej effektywne
chlodzenie, a pracuje pod mniejszym obciazeniem.
Jest to rowniez bardzo wazne jak zasilanie nie jest dobrej jakosci i
czasami prad siada, z zabezpieczeniem czy nie czesto rujnujac
zasilacze.
Cena jest tutaj mniej wazna bo to sa roznice groszowe po oplaceniu za
przesylke, ktora jest bardzo droga w porownaniu do kosztu sprzetu.
W przeszlosci spalilem juz pare 450 W .... bo sie po prostu
przegrzewaly ....

The NVIDIA GeForce 6800 looks like a promising bid to make NVIDIA strong
again, but the star of the show, the 6800 Ultra, wasn't all flash and
glimmer. Rather, the card proved rather large, consuming an extra PCI slot
because of its girth.
Big boys need big breakfasts, too, so the 6800 Ultra consumed 120W and would
require a 480W power supply unit.
A good quality 350W power supply with a sufficient 12V rail pull can support
the 6800 Ultra standard clocks of 400/550.

A lot of reviewers have already shown that they are running on 350W power
supplies with no problems. Overclockers will still want the big power supply
and will want to connect both molex connectors.
We are putting production tests in our manufacturing line to ensure this [new
350W requirement] is the case and will be lowering the spec.
So, it's still not going to work in that retail shelf purchase you made at
Circuit City, I'm afraid, but it looks like most enthusiasts may be good to
go provided they don't already have everything but the kitchen sink in their
box.
But the situation is still a little dicey, inasmuch as it sounds like not all
350W power supplies will do the trick.
I wouldn't be too surprised to see an approved list ?a AMD before too long.
In related news, the Inq is reporting that the 6800 Ultra Extreme, which
takes the core memory from 400 to 450MHz, will not be shipping to retail
outlets.
Apparently those cores are rare right now, and NVIDIA is going to reserve
them for special partners.
As most reviews found out, the nVidia original recommendation was extremely
conservative.
We looked over this in C&CF earlier and drew similar conclusions. For
example, Tech Report uses a 400W Antec on their Athlon64-based test box and
shows less than 206W of power draw.
A more heavily loaded system such as Tom's Hardware shows only 288W maximum
power draw on their test box.
Simply put, with a quality 350W power supply, most existing typical systems
should be just fine. An easily available quality 350W unit such as this one
has a +12V rail at only 16A sustained, but it should be more than sufficient
in an existing "typical" system.
Those building new Athlon64-based boxes should consider playing it safe with
a larger power supply since it will give additional expansion headroom, but
strictly speaking, it's not always going to be necessary.
Finding out the actual current draw of the 6800Ultra on the +12V and +5v
rails might be very helpful for those who wish to pull out calculators and
see how close to the edge they're running.
(FWIW, the ATX12V power supply design guide 2.0 increased +12v current
requirements to prepare for BTX. In ATX12V 1.3 their "typical" 300W
description was +12V@18A sustained; in ATX12V 2.0 is is +12V@22A sustained.)
