8910 PSU upgradeable with aftermarket PSUs?

ATX 20 pin is the standard from 1990.  24 pin EPS12V @ 80 percent efficiency is the norm.

I have an 8900 and its a standard 24 pin eps12v 460W power supply.

Power output on more than just 12v rails counts however thats why EVGA B1 is fine but EVGA B2 BQ G2 is not.

Specifications

Service Manual

I just want to make sure that a standard atx psu can fit in the slot on the 8910 without any modifications.

FYI just purchased a corasir ax860i and an asus geoforce gtx 1060. The service manual states these large size gpus can fit in this chassis.

Hi,

Thank you for posting and willing to help but i am confused by your posts.

I updated my post to reflect the psu change. I ordered a ax860i.

Are you telling me i need ot get an evga psu that you mentioned?

I recommend EVGA EVGA SuperNOVA 750 B1 110-B1-0750-VR   version.   B2 BQ G2 models do not work with the same WATTS spec. This is known working B1 in many models.  B2 Not working.

AX860 only has LESS THAN 150W on these rails.

Amazon is probably mad at me. In the last hour Ive probably cancelled 2 psu orders.

I went ahead and did the evga 850 platinum edition because im adding a larger gfx card with 32gb of mem, a 512 950 and 512 m2. For the on board mobo for backup. Rather have the extra 100 bandwidth .

This isn't my first rodeo with dell but this 8910 is a new design and i dont know what can fit and what cant in terms of the psu, and i have been unable to find discussion on psu installs on this chassis.

I do appreciate your help.

It will be interesting to see if the 850 platinum works at all.

Ive used the EVGA NEX 750 B1 and G1 in XPS 8500, 8700, 8900 and it works fine.

There may also be Physical Dimensions issues aka the other reason the EVGA Super nova 750B1 or G1 is chosen is because it physically fits inside the case.  The label below is from the Super Nova B1 750W

The 850 Platinum has even LESS power maximum on the other rails which cannot be ignored.

Dell 460W unit  has 142W on the 3.3v/5v rails.   PCI-E slots use this for slot power up to 75W.  Also has 3A on the +5vSB not 2.5

Dell 875W unit has 225W on the 3.3v / 5v rails  4AMPS on the 5VSB rail where the EVGA has 2.5.

EVGA 850 Platinum has 100W MAX on the 3.3v/5v rails.

Power supplies have a Max Rating on Multiple Rails.   Looking at a single spec of WATTS and 12v ignoring the other rails is a bad IDEA.

At some point i have to try something. So the 850 will be here in a couple days.

If the pc doesn't power up, ill look for another option.

Your post are soemwheat helpful but when you list that a certain rail doesn't have this or that, that doesnt mean much to me because im ignorant to the downsides to that.

I choose the psu with the rating first, then power, then i scan reviews. Ive seen nothing but praise for this psu, yet you tell me it ***.. :)

Id ike something better than 80 bronze so the ones you have are not on my radar. I prefer platinum.

This machine is not going to be used for gaming or mining or birthing kittens, so im not sure what damage it going to cause?

Again  I appreciate your intense responses but you don't have to brow beat a brotha.. :)

When a power supply is overloaded on a rail it shuts down or pulses or never turns on.   150w reduced to 125w or 100w on the 3.3V/5V rail is specific.   There are more than 20 potential problems with overloading a power supply.  Gold or Bronze isn't the issue.  Physical Size and MAX OUTPUT current on more than just the 12V rails is.   Specifying that ANY power supply with a WATTS rating should be fine ignores what is going on for everything but the 12V rails.

Pulsing can cause capacitors to explode and a motherboard fire.

It can also damage hard drive and ram etc.

Reading from the actual http://pcisig.com/ documentation:
Quote: A 300W add-in card can receive power by the following
methods:

75W from x16 PCIe® connector plus 150W from a 2x4 connector
plus 75W from a 2x3 connector.

75W from x16 PCIe connector plus 75W from a first 2x3
connector, plus 75W from a second 2x3 connector, plus 75W
from a third 2x3 connector.

Note that this is not the preferred approach.

Thank you for the continued discussion.

Clearly you have me at an advantage here in regard to  psu speak.

So you are telling me when I install everything with this psu the computer will tick/click/cycle on off then blow up with his highly rated platinum psu?

Not trying to be thick, I just am trying to get the laymens response here. Ive never seen so much negativity  on a psu of this caliber so this is why im trying to get a laymens feel to all of this.

Not sure why my post  is being moderated since i started this thread...

Like i said, i have to try something. I dont want a gold or bronze psu. I can't believe the platinum series is WORSE than bronze when i see reviews that state this psu is of good quality.

You bring up all these "issues" with rails and such without telling me what potential problems those things you list may cause...

If the psu doesnt fit, ill leave it outside the case. This will not be a gaming machine,a VR machine, a mining machine or a machine to birth kittens. Its just a machine that i will use to do audio recording and may have multiple browser tabs up.

I will follow up on my success or failure once i get all the parts in and running.

Hello!  The platinum, bronze, gold, whatever speak that a lot of PSUs have from what I understand mean the quality of the power going to your computer, not the wattages on the rails and blah blah.  Like you i was reading all of this and a bit confused but just remember that just because your PSU is platinum means nothing but the quality  of the power, not the juice going into the computer.  

Another example is 'Platinum' water would be 100 percent pure water with nothing added, where 'Bronze' water may contain up to 10 percent trace elements and minerals.  I hope that makes sense.

As title asks, is the PSU in the 8910 standard ATX or some other configuration that is compatible with aftermarket PSUs? I dont have the machine yet and am looking to get ahead of the curve on some upgrade parts. Cheers...

The other thing to consider is that if you're already planning major upgrades down the road, this might be the wrong system with which to start.

You can easily build yourself a custom system out of completely standard parts and avoid the upgradeability trap built into most brand name systems. Alternatively, there are also vendors that will custom-build you a gaming rig out of completely standard ATX mainboards, power supplies, cases, etc. that you can use and upgrade for years.

Pre-built, name-brand systems have their market - that market is NOT the one where power users, tinkerers and upgraders live -- that market is far better served by the likes of the parts sellers (Newegg, etc.) and boutique builders (AVA Direct, Falcon Northwest, etc.).
