Power supply for HD2600XT

[Guest]

Hello,

I have just bought myself a Gigabyte HD 2600 XT video card (with 256MB
of GDDR4 memory). i primarily wanted to use it for a home theatre
system that is housed in an aspire cube case. The case has a 420watt
psu. On the 2600XT's box it says you need a 550 watt power supply for
single card but at same time says you need a 550 watt power supply for
crossfire. I will only be using the one card. Anyone experiencing
issues with this model card (or similar) using a 400-450watt psu?

Any feedback appreciated.

Your 420W should do the job just fine I will guess, but it also
depends on the rest of your system (and if's a normaly good 420W).

Personally I had the _2900XT_ in combination with a Athlon 64 FX-62
running for quite some time with a 430W Antec PSU. Somewhat noisy PSU
under heavy loads, but it works....

The recommendations would be for an average user that might buy a 550W
supply that can only produce 300W. What you should have is also going to
depend on what else is in the computer drawing power. Knowing the capacity
of each rail can help avoid grief too.

Good place to start in deciding. May be under reconstruction though.

this might be a stupid question to ask but i am going to buy the same
card radeon HD 2600XT, the pci express version, and i was wondering if
my psu which puts out 375W of power will support the card because the
website (http://visiontek.com/products/cards/retail/
2600XT_PCIe_512.html) says that the card needs 350+W of power, also
how do i connect power to this card, i am kind of a noob here so any
help would be appreciated.

The ratings are an estimate. ATI recommends 400W for their similar card.
They don't know what else is in your system. Some supplies don't put out
their rated capacity. If you overload a quality supply your system won't
work. If you overload a crappy supply it may damage your $y$tem while it's
going up in $moke. This is something you really should know what your doing.
Use Google if necessary to figure out how much power your system can
consume. Then compare it to your supply. If the supply doesn't have or you
can't get detailed specifications it's probably in the crappy category. My
guess you'd be on the edge with a quality supply.

Power supply section, over half way down, gives some useful info and more
links.
Great thread for anyone contemplating a HTPC build, BTW.

This is from a link on the above page.

Even the free calculator on this site seems to have a little more accurate
database than my previous link has at present. 303W just for my aging P4
system. Another DVD burner would put me close to the 350Watt supply I'm
using. You may want to use the pro version or figure out rail amperages
another way.

Asking in one of the homebuilt PC newsgroups is another option.

Check the manuals at visiontek for connectors.

God Luck.
