Upgrading to a x1800 512

Hi! I will soon (within the next few weeks) be upgrading from a 6600GT 128mb to a x1800XT 512mb. I currently have a 400w PSU (Codegen 300x) and its powering:

Asus K8N4-E motherboard
1.5 GB Ram
a 160GB & a 320GB Hard drive
1 NEC 3540A DVD RW Drive
Geforce 6600GT

I'm assuming that my PSU will not have the required wattage to run (or properly run) a x1800XT. What is the minimum wattage you would recommend? Also, which PSU make/model would you recommend?

Thanks a lot! :)

I was always told its the amps you need, not always the Watts :p :confused:

The Akasa has 20A if i'm not mistaken, which should be enough. I like to have a little leeway though, for more overclocking\future upgrades.

So how come say a 600 watt cheapo psu can only have say 16 amps, and a decent tagan 420w can have 23 ??


becuase generally they cant - they say ther psu can give a lot of amps, when it will actually die

link me and ill try and be more specific

I dont have a link sorry :)

It just reminded me of when i built my first pc with my dad, and i he bought me a psu from " Cant Say Because I Will Get Botty Slapped :p " it had quite a high rated amount of watts, but there was only 16amps on the 12volt rail, so i bought myself this tagain :D


Im not trying to argue with you btw, im just curious :)

Thanks a lot guys :) It seems that I will need to get a new PSU seeing as mine only has 16A on the 12V rail :(

Would the Ultra X-Connect 500W (CA-004-UX) be ok? It has 34A on the 12V rail.

Thanks again :)

Its just marketing, u can describe a PSUs performance in more than one way. The favorite for sound systems is to quote peak to peak output where as the waveform will spend only a short time at its peak during one cycle. The more accurate way is to quote RMS power, this is just a mathematical way to add together the area under the graph so to speak.

id splash out on a decent psu if i were you. I used to hae a 300watt one that came with the case i got for £22 and it knackered 2 of my hard drives and i lost all my uni work, shed loads of mp3s (over 10000) films and games. When i used to burn cds and connect a couple of 80mm fans and overclock my 9800pro drives would turn off and sometimes even restart my pc!


i now have this (hiper type R 580watt) powering an overclocked x1800xt, 2.8ghz opteron 146 and a few other bits

no problems yet, was £80 but at least my computer wont die on me now!

I'd still recommend Enermax\FSP\Seasonic\Tagan over Hiper.

By the way, its HMRC now, not Inland Revenue ;)

recommend away, just saying mine has been stable since i bought it about 4 months back.

cant be bothered to change, most know who thay are

Not saying Hiper is necessarily bad (certainly better than a generic) but given the choice available...

not wishing to get into an argument here but what are you basing this upon, have you had a few hipers blow up on you or something in the past?
