Power Supply (PSU) Tech Guide

[voyagerfan99]

Plenty of times before. Driver updates, Windows reloads. I just want to see if I can find a solution. Otherwise I'll live until I build a new rig or update my GPU.

Sometimes my games freeze up, the audio screeches, artifacts appear, the game crashes, and everything artifacts until I reboot my PC. It's weird. Anyway, done the usual driver update and so on?

i had issues like that before when i was overclocking the igpu on my emachine, then stopped and it stopped, just thought i'd mention since you have a superclocked edition.

I've gone through 5 video cards, two CPU's, at least four kits of RAM, two SSD's and two PSU's. So no. HDD has no errors either, I scan that regularly. I'm beginning to think it's a windows 7 problem.

I've had it for maybe 6 months. I get random video driver crashes (that can recover) and other video crashes that don't recover and reboot the system.

I had the same issue with my other 750W Antec PSU; that's why I got this one.

Doubt its a P/S issue. The Cooler Master is ok, but it really only has in the 450W range on the 12V rail. I've seen that happen with a issue between a sound card and video card driver.

Like, I had more issues when I had my X-fi Titanium installed it crashed a lot more. Not so much these days, but it still happens.

Have you tried with just the onboard sound and see what happens?

I've had the sound card out for a while now. Like I said, it happens, but not as often as it used to.

 

[StrangleHold]

Maybe try uninstalling your sound drivers and disabling your sound in the bios and see what happens. Anything just to try tracking it down.

Would it be bad if your PSU wattage matches the video card usage exactly? I have an Antec 750w continous PSU and a ATI 6950 video card. I saw the list states that crossfired 6950's require 750w. Should I upgrade to a 1000w PSU?

You don't understand the chart. The chart means if you are going to crossfire 2 6950's then you need a 750 watt psu with that many amps on the 12 volt rail.

So the chart is the recommended minimum size PSU that you should use with a particular card(s)? Good to know I don't have to buy another PSU . Thanks

Everyone,

I will get around to updating this list again, bit more difficult working full time but I promise that it will get done in the next month

This is probably what ill be getting

I have a few questions.

HD 6990 Crossfire.....................850W ..........................54A

Isn't the amperage determined by (Watts/Voltage)? If the HD 6990 is 850w, why isn't the amperage 71?


How much headroom should I allow for when buying a power supply?

 

[Darren]

It's 54 amps off the 12 volt rail, not across the whole PSU.

Obviously more is better but you should be fine with 850 watts for that setup as per suggested.

I would say 25% headroom. Need 400W? get 500W. Need 600W? Get 750W

Pretty much covers everything ive been spruiking for years.
