XPS 8910, PSU upgrade, #8

Standard EPS12v unit like EVGA 700BR OR 850B works but if you have the optional optical drive you need a 15 pin to 6 pin sata power adapter as this is not standard.

Sweet thanks I will check it out!

I’m having troubles understanding what you mean but this is the psu I’m thinking of, would it be ok if I used a converter on it?

It actually has 2x 2 pin my bad.

that EVGA is definitely great.  It has a single 12V carrying 58A.  12x58=696W.  single 12V rails design is much better than the old multi-12V psu used by Dell oem.

my new rtx 2060 has a 6 pin pcie and a 8 pin pcie would it work if I got a 6 pin to 8 pin adapter?

the psu you recommended Has 2x 6pin and 1x 2pin, the gpu I got requires a 6pin and an 8pin, so if I use a 6pin to 8 pin converter Will it work?.

If the psu have two 6 pins on two separate 12V rails then it is okay to convert one 6 pin to 8 pin using adapter.  some 460W psu already includes 6+2 pin connector good for 8 pin.

for example, in this Dell psu GJXN1 there are three 12V rails. one can assume the 12VA and 12VB carring max 18A and 16A are for the two 6 pin gpu connectors., Dell uses the same 460W oem psu design for XPS 8930 and Aurora DP/N DM1RW.

make sure the 6 pin have 3x12 V leads wired.  many power supply designs actually include the third 12V wire in the 6-pin connector anyways. In that case, there isn't much difference between the 6-pin and 8-pin, other than the two additional ground wires.

RTX 2060 recommended system psu is 500W.  you may be ok with stock 460W same reason.

you can get any standard ATX 550-650W psu to upgrade the stock psu.  recommend a reputable name brand such as Seasonic, Corsair, or EVGA.

The motherboard in 8910 accepts standard 24 pin ATX and 4 pin CPU power connector.  You need two 6 pin gpu power connector to make one 8 pin connector for the GTX 1070.

460W may be enough for GTX 1070 though.  Nvidia recommendation of minimum 500W may be a bit exaggerated to accomodate all possible builds using the 1070.  Its small print disclaimer is that prebuilt system may need less power.  You will find out whether your 460W is good enough or not pretty soon.  When a gpu is significantly under powered you may experience freeze or blue screen or system random shut down.

Thanks for the response, I am not installing a gtx 1070 I am installing a rtx 2060, I read on another thread that a 460 w psu only supports up to a gtx 1070

EVGA 700BR has 2X  6+2 aux pci power connectors.

6 pin + 8 pin implys that the card needs 300W from the power supply.  The 8-pin power connector can deliver a maximum of 150W to your graphics card.  8-pin connector = two 6-pin connectors.   6 + 8 = 75w from slot 75w from 6 pin and 150W from 8 pin aka 300W

Thats why you need more than 460w.

Sorry but I’m still lost on what you are saying, would a converter work with this psu?

Oh ok cool, also you suggested I get a modular psu, I thought about that but I’m very knowledgeable about all the cords I would need.

So if I have a gpu that needs 8pin and 6pin for the 8pinbi can combine 6 + 8 and it works?
