Best GPU for 350 Watt PSU - Page 2

post #11 of 33
350 watt... powering a i7 2600k? Buy a better PSU because you basically cant get a card which has either a 6 or 8 pin PCI-e connector simply because that PSU wont have enough juice.

Assuming its 80+ at all times, that leaves you with 280 watts. 1 6 Pin will take around 75 watts plus the 30 from the PCIe slot leaves you very little to power your CPU socket and mainboard, not to mention the HDD's and other things.

I would really consider at least jumping up to a 500/600w from a good brand like corsair or something.

This is probaly an HTPC comp, not a mid size gaming rig.

That's not how it works at all.

Assuming it's a good 350w, 350w means 350w. The fact that it's only 80% efficient means it'll be pulling 420w from the wall at 350w of system power.

QTF.
Please people do some research before posting things that are utter crap.

Silverstone ST45SF. It's actually a 450 but man people are getting "chirping noises" when they are hitting 400+

I should have asked but what are the primary and secondary uses?

How am I cheaping out? I have the highest wattage PSU that is easily available for a SFFS.

IMHO 560ti is the card then.

No, it depends on the quality of the PSU. A crap PSU might be able to instantaneously supply 350w for a short period of time, but under longer heavier loads, it might not be able to sustain that output for long, and put out significantly less than what the rating states.
