Dell XPS 8900 upgrade help.

[CompUser08]

Hello. I recently bought the 8900 and I was wanting to upgrade the graphics card from the stock 730 to the PNY 1080. But, I am not sure what power supply will be able to fit perfectly inside the computer case and if the stock motherboard will have the connections to be compatible with the PNY GeForce GTX 1080.

Also speaking for the power supply, I want to be sure that the power supply will also have SATA power cables to power all of the optical disc drives and all of the hard drives just like the stock Dell OEM power supply. One 5.25-inch ODD bay is occupied by the stock CD/DVD Writer and there is already the stock hard drive. Which leaves one free optical drive bay and two hard drive bays.

Sorry, this is my first Dell computer. I could build a computer but I am not smart enough nor am I tech savvy.

My 8900 has the 6th Gen Skylake CPU and I think the chipset is an Intel Z170.

Check the size of the psu you have and the room you have extra.
For a 1080 and as it seeams you have lots of drives I would go with at least 650W.
I got a XFX XTR 750W for a pretty good price.
Or just go with any Seasonic you like with at least 650W.

I am not sure about the size of the PSU. I think there is plenty of room to move around in the case so it cannot be that big of a power supply. How about a power supply from EVGA and I am hoping for a gold and full modular. Any recommendations are welcome.

I will be playing the sims, as well as web browsing, listening to music, watching movies, and converting videos.

The basic Dell XPS Specifications are

Intel Core i7 (6th Gen) 6700 / 3.4 GHz
Intel Z170 Express Motherboard
8GB DDR4 SDRAM
1 1TB HDD SATA 6Gb/s
1 DVD
Power supply 460 Watt

Now taking theses settings and changing the puny GT730 and putting a GTX 1080 (which in reality uses less power than a GT 730) you end up with a power consumption of
OuterVision PSU Calculator part list
Motherboard: Desktop
CPU: 1 x Intel Core i7-6700 CPU Speed: 3400MHz CPU Vcore: 1.2V
CPU Utilization: 90%
Memory: 1 x 8GB DDR4 Module
Video Card Set 1: 1 x NVIDIA GeForce GTX 1080 Core Clock: 1607MHz Memory Clock: 2500MHz
Storage: 1 x SATA 7.2K RPM
Keyboard: 1 x Standard Keyboard

Computer Utilization: 8 hours per day
Load Wattage: 326W
Recommended Wattage: 376W

according to this configuration, your 450w power supply would be plenty to handle a 1080

now how many hoard drives do you run on this computer? tested with 3 HDD with above configuration and it can out: 398W still under 450w.

I am currently running one but I plan on adding two more if possible. Although Dell support told me that I can only fit either another 5.25-inch optical drive or a 3.5-inch hard drive in their respective bays, since I will not have enough room for both. I was thinking of putting an SSD, but I want archive storage more than fast boot times at the cost of finite write.

I could stick with the Dell OEM power supply, but I am wanting a better power supply that can have the SATA power cables to be removed in case a SATA power cable were to fail and it could be replaced with a new SATA power cable.

I found out that the power supply dimensions is 6"x5.5"x3.5", which I took from an internet search. I now need a power supply that matches these diminsions so that the new power supply will fit inside the 8900 case.

 

[The Paladin]

Right, So 6x 5.5 x 3.5 in mm is about 152mm x 89mm x 140mm in dimensions.
According to the wiki.com pages ATX power supplies generally have the dimensions of 150 × 86 × 140 mm
so it seems any standard power supply will fit your case...

Power Supply: Corsair RMx 650W 80+ Gold Certified Fully-Modular ATX Power Supply ($99.99 @ Newegg)
has dimensions of 3.39" x 5.91" x 6.30"

 

[CompUser08]

Cool. I just need to know if the power supply will be fully compatible with all of the hardware inside the computer since this is an OEM build and I do not want to kill my computer since it is irreplaceable and everything, almost everything is custom manufactured from Dell for the 8900. I also want to protect my investment, too.

I cannot seem to decide between Corsair, EVGA, or Seasonic. I know it's a power supply, but I also want reliability.

The Seasonic PSU will be here soon. I now am looking for the perfect graphics card to play "GTA V" in "native" 4K with game settings fully maxed out all the while being able to drive a 5K monitor. I was leaning towards either the NVIDIA GTX GeForce 1080 or the NVIDIA Titan X (Pascal). I'm concerned about 60FPS, 120FPS, etc. I really cannot tell the difference in the frame rates. All I want is flawless and buttery smooth performance with no lag, stutter, freeze, etc. Please help me. Thanks!

what is your monitor make and model ? butter smooth depends on your monitor and what resolution are you expecting to play at 720p, 1080p, 2K, 4K, ?
