Stop recommending 650W-850W power supplies for single card systems - Page 2  

post #11 of 286
LOL, but they can upgrade their motherboard and add another card too. I don't care the slightest, but I think sometimes people's psu outlast their components when they switch arch so quickly.

Phaedrus its time to stop dedicating YOUR LIFE to telling people they have too many jiggawatts....

after all... this is OCN and we do it big.

EDIT: I don't get why you don't mention quality???

"then recommending a 650W or more is wasting their money."

My 700 watt StealthxStream could not handle my 6950 + 1090t overclocked...

The same error or complaint "you have too much......" can be placed on many different components within the PC, not just the P/S. Isn't anyone going to take up the cause of "too much RAM" or "too much cpu", or "too much hard drive space". At least with the P/S buying a 850w when you really only need a 500W is not such a tremendous difference in cost.Pretty much harmless. I will comment I have never been harmed by "too much wattage".

...Should I punch that guy, which gave me that advice, in a face if I ever meet him? rolleyes.gif But I'm convinced that there is at least one advantage left - heat output. It must be considerably lower at < 50% load.

And in all fairness its not really that big of a deal. They have google.

You are wrong here. Actually, 600W psu's are just useless, because they are on the middle of nowhere. On one hand, you can easily power any system that has only one GPU no matter the overclock you put into it with a 500W psu...and on the other hand, you will struggle with a high-end multi-gpu system. All in all: a suboptimal solution.

This is why is better to get 500-550W or 750+ W psu, because with the first ones you are perfect to power any single-gpu solution and the second one is much more adequate for power hungry multi-gpu solutions.

FYI

Yeah it could. It could do Crossfire. It's an ok 700W. It does have an issue with the solder joints on the +12V rectifiers going cold after a couple years (using too large a diode package for the PCB), but that just leads to a silent and harmless failure with low risk of component damage.

If you tried it and it didn't work then it was a faulty unit and could be RMAd.

A quality 650W will run any two GPUs except HD2900XTs, GTX275s, GTX280s, GTX470s, GTX480s, and GTX580s.

GTX570s, HD6950s, HD6970s, GTX285s, etc are all fine in Crossfire/SLI.

This is assuming a highly overclocked Nehalems CPU; with a more power efficient CPU you could naturally run more.

Advice is free and is the opinion of said person. Doesn't mean what they say is correct, but it gives you a good idea on the route to take.
