[SOLVED] Best PSU for a gtx 970?

alankulczynski · Oct 11, 2018

So I'm buying a gtx 970 but it says I need 2 x 6 pic pin psu, I'm making a budget build and can't find any cheaper ones, I'm looking for 500w and nothing more really, I also don't know if it's easier to convert a 4 pin to 2 x 6 pin?
Any suggestions and known PSUs you might know would be very welcome

That simply means that you need a PSU that includes 2 pieces of 6-pin connectors. Most of them do. Also, note that 6-pin connectors are always separated into 4pin+2pin attached to it or 4-pin+4-pin attached. So you're fine.

What is your budget? I'll help you recommend one.

julienruc :

PCIe AUX connectors aren't 'always' 6+2 but those are fairly common. Solid 8-pin is particularly common when the PSU strings both an 8-pin and 6 or 6+2 pin connector on the same cable. 4+4 however should NEVER be on a PCIe AUX cable, 4+4 should only be seen on the ATX12V/EPS12 CPU power connector. The keying order is different, spacing is tighter on PCIe connectors and the pin polarity is inverted compared to ATX12V/EPS12. You do not want to mistake a PCIe AUX connector for an ATX12V/EPS12 one.

Ahh thanks for the clarification, do you have any idea for a cheap psu that works well with the 970x?

Any decent 520w/550w is more than capable of powering a system with a gtx970. Regardless of wants, there's not a single 500w psu I'd even consider recommending as decent.

here is evga from amazon 600w bronze. 600w will actually save you money in the long run. power supplies are most efficient near 50% usage. there is a 500w PSU but i recommend just spending the extra couple bucks for upgradability.

kidsmoddingstudio :

Most PSUs' efficiency is relatively flat from 30% through 70%, especially those with genuine 80+ ratings where they have to meet minimum from 20% through 100% and are only 3-5% more efficient at their peak efficiency.

If you size a PSU to be at 50% load when the system is near absolute maximum load (300W is where a typical enthusiast system lands without extreme overclocking), your overall efficiency will be worse since the PSU will be at 20-40% load most of the time instead of hovering around peak efficiency at 40-60% through gaming loads and falling under 20% under light loads where there are no efficiency requirements under 80+ at less than Titanium rating.
