These parts and 480w power?

Doomulation · Feb 24, 2006

It's safe to ask, even though I saw some resailers selling Athlon 64 X2 and Geforce 7800Gt with a 480w supply... is it feasible? Should one get more power for a supply to be on the safe side? These two are quite demanding I would imagine...
Perhaps I should mention it is this card: http://www.evga.com/products/moreinfo.asp?pn=256-P2-N517-AX

It depends on PSU quality. If PSU is real 480W ( for example Antec TruePower) then it's ok, i've used Wildcat Realizm 200 + 6xHDD w/ 450W PSU. But if it's 480w=300w crap like LinkWorld, LCT, JNC etc. - anything can happen, even smoke

Don't count on it - I shall have a 500 watt high-quality psu

Well, in that case you don't need nosmoke.sys driver from MS

just passing by..

you can look here
or here

i maybe misunderstand this thread with my engrish, i dont know and i dont mind, im tired...

Cool! A calculator for calculating how much watt on average your system would drain. I got on average a 414 watt.
Thanks for the link. Very interesting!

The overall watt is not the importent thing, you need to check (ehm lack of words ^^) how much power (A) the psu can deliver on the 12V rail.

I've learned that by now actually, and I have made sure that the PSU selected meets my demands.

What's a 12v rail?

Doomulation · Mar 6, 2006

The wires that stick out of the PSU are of different voltages. A PSU may have one or two wires that output 12V and those are important when buying a PSU.

Just a +12v line in other words. On modern motherboards for P4/A64 CPU VRM (voltage regulator module) is powered by 12v, high-end videocards have +12v connector too, and of course HDDs, FDDs and CD/DVD drives. +5v is important when you have 4+ PCI cards or lots of USB/FireWire devices connected.

arnalion · Mar 6, 2006

Yup... the three "main" rails are +3,3V +5V and +12V. Some of the best power supplies manufacturers are Tagan, Seasonic, Antec and Hiper. I would especially recommend Tagan and Seasonic. I must warn you for Q-tec power supplies (crappie shit

), a 650W Q-tec delivers around 300W constantly (650W peak)

Only the AGP ones, the PCI-E ones doesn't need it

Doomulation · Mar 6, 2006

There is also an PCI-Express connector I think... the latest cards like the Geforce 7800GT requires one of those. They cannot survive on the Pci express power alone.
One should always check the 12V rail, as it should at least pump out 24A or more. There could also be more than one 12V rail, so combine those amperes then!
Often (AFAIK), today's PSUs pump out more than enough A on the 5V rail for a system to survive, so you really shouldn't have to worry about it.
The total watt is the V * A of all the rails.

Nope all new high-end PCI-e cards have a PCI-e connector which absolutely needs 12V. But there can be diffrences between the AGP and the PCI-e. 6600GT (if it's AGP) needs an extra contact for power, but the PCI-e version doesn't, and that's because PCI-e can give more power.

Add Enermax and Zippy here.

There's alot of other PSUs, not power supply, but piece of shit units - LinkWorld, Gembird, GIT, LCT,JNC,Codegen (Super Power), etc. If you want to equip your computer with self-destruct device - buy one of these

WhiteX · Mar 8, 2006

There is a Brazilian solution that is working very well here, it is Kmex.
I did some testing with the multimeter and it performed very well.

PSU = Power Supply Unit

This bad boy has everything. 350W with 26 amps on the 12v rail. Supports P4/AMD 64 12v 4 pin connector, SATA connectors, PCI-E Power connector, Motherboard Fan Speed Monitor support connector, Adjustable fan speed and best of all it has a 20 pin ATX power connecter and a snap on 4 pin connector for EATX (24 pin) boards like the ASUS A8N-E (another good product). Plus its quiet. You can't go wrong with this one, its compatible with damn near everything, made by a quality company, and has enough power output for most systems. This is probably the best PSU I've ever owned.

These parts and 480w power?
