6 to 8 pin PSU conversion

Solution
If your PSU does not have the required cables for your GPU, you need a better PSU.
If your PSU is an "ACE 850 W" that costs "£32.00", you need a better PSU.
@ aadilsidat9:
Even if it lives up to its claims, the outputs are for a unit several generations old: High outputs on the +3.3 and 5v rails along with a meagre 46 amps on the +12v rail; half decent 500 Watt units can do better on that critical +12v rail ( current systems don't use much off the 3.3 and 5v lines ) .
Add the Floppy connector and a single 6 pin PCI-E cable and it looks more like a 500 Watt unit designed over than 6 years ago than a 850 Watt part built recently.

So, yes, agree totally with richiestang_78: Replace it, 650Watts will be plenty for a single GPU system.
 
Hi

If a 850 Watt PSU does not have at least 2 PCI-e 8 pin plugs it is very poor quality, and should be avoided.

It also has a 4 pin 12V cpu plug instead of a eps 8 pin or 4+4 plug so only supports relatively low power CPU's

so what motherboard & CPU do you have?

Yes, that will work great.
 
Yup, while the EVGA 850 G3 is overkill unless you're using multiple GPUs or need a lot of SATA connectors (I have a 750 G3 both because I needed all nine and because I got it at a ridiculous price of $70 during a Newegg sale), it's a terrific power supply.

Richie's suggestion at looking at a SeaSonic 550 is a very good one. Both the SeaSonic Focus 550 and the EVGA G2 550 can generally be found at very good prices and are frequently on sale at various retailers.

And yes, the power supply you have is truly frightening!
 
@ aadilsidat9
As has been said, 550W would be enough, or you can overkill a little with 650W if you feel you may need the extra power for the later GPU upgrade.

Both the Seasonic Focus, EVGA G2 and G3 are excellent choices although prices here in the UK are much higher than in the USA.

Amazon can provide some real bargains, but at times their prices are also way above the norm, try using Pcparticker: https://uk.pcpartpicker.com/ to more easily widen your search. Also, take note of the suppliers they list, many will have special deals that are often missed by price comparison sites.

Good hunting!

 
Well as i said earlier i was planning on upgrading my gpu and the 2080 ti on nvidias website recommends a 650w power supply hence why i picked a higher wattage supply before. so am i to take whats said on nvidias website with a pinch of salt? Or should i stick with your recommendations?
 


They generally over-recommend because so many use average-to-horrible power supplies (the one you linked is definitely on the latter end of the spectrum). An excellent 550W power supply would be just fine, but most of those excellent 550W power supplies have slightly more expensive 650W siblings, if that makes you more comfortable.
 
It's really going to depend on what actual 2080Ti it's going to be in the end.


Like the 1080Ti's, some pull quite a bit of power well over 300W...


But we will have to wait until actual reviews come out etc.

I would say a good 650W would be a safe bet, but then that might not really be enough depending on the actual card/OCing etc.
