Hey, thinking about upging my PSU because i feel a impact after using too many usb connections and it screaming, RAN OUTTA POWER FOR USB DEVICES. and turns off my keyboard and mouse. ;|

ill have the money soon but all i need to know is, what cheap one (under 80 if poss) could i get that would provide atleast 650+wattage.

The MB i have is a ECS nForce6M-A

which searcing on google will show you more spec about it. i am thinking about UPGing my GPU aswell, if you could find a suitable one capeable of DX10 or above or even DX11 which is soon on its way, and to provide enough space such as 768mb

it is a gaming PC so i need it to be sufficent for all USB devices such as a headset almost all the time as i use the gaming for Vent and TS. possibly also a part time server so something that can handle the pressure would be cool. i am also going to start folding@home software so ifi could get a nice GPU to render that nice it would be brill. thanks alot !

Max money :

I have around 120 - 150 to spend, hoping not to spend over 100 since it is going to be for my pressent for easter type thing... please find me a nice spec PSU and a decent GPU for gaming, my current is a bleepty Sparkle PC NVidia 8600GT 512mb which has gave me one or 2 BSOD's due to it's drivers not running correctly.

~thanks!

Hi

The power supplied to your USB devices is not a limitation of your PSU. It is a limitation of the chipset on your motherboard and is in the order of 500mA.
In theory you can run up to 127 devices, including the hub devices from a single host controller. However you will hit problems (as you have done) unless you use USB hubs which are self powered i.e. hubs which have their own power supply.
Buying a new PSU will not solve your problem. Buy yourself a self powered USB hub instead.

well, if you upgraded to a better motherboard or bought a self powered hub you could. :D

There's a set standard for power supplied to the usb bus, it's the same for all motherboards

A weak power supply might aggrevate this

Get a powered usb hub!

No. Try not. Do... or do not. There is no try.
