The Dell PSU is thicker than the aftermarket ATX units so the swap doesn't work the other way sometimes. Also Dell makes the cables just the right length for each Dell system so you can have issues there depending on which harness you get.
The Dell PSUs are multi rail. the power from the T5500 2nd CPU connector might not be available to power other devices depending on which rails are going to it. A single rail aftermarket PSU has all the power available at all the connectors as needed. It's more of a "universal" solution. But the T5500 PSU is a known solution as long as you get the wiring harness with the extra connectors.

You have a RTX2080 correct? Which system do you have it in? Cause I am reading that 2060 doesn't work in Legacy. So that would mean that pretty much the RTX series are no good for the T3500?

Correct. Mine plugged right in and worked first time, no issues. Maybe the Founders Edition cards are limited to UEFI? EVGA's are not.

So the 525w harness works with the 825w unit?

Yes, the wiring is the same.

Though they would still be limited to a single 6-pin for GPU power.

On one of my T3500's I got a 6pin to dual 8pin "Y" cable. The electrical load isn't a problem and everything is stable so it will be ok for the card Rock will be using.

I think you might be right on this.

@rock
If you are going to go with a 2060 it might be a good idea to go with a brand that supports legacy bios, such as EVGA, Asus, Palit, Galax, MSI or Gigabyte.

mm oke oke yea im looking to get a deal for a gtx 1080ti so im probably gonna get that

so a 6 to dual 8 pin is good to power a gtx 1080ti if i use the dell t5500 psu?

my other question is: ur rtx 2080 is pcie 3.0 yea and the t3500 pcie socket is 2.0 will that impact any performance or just a little bit?

That's a great card, however there is one catch, the 1080ti is a high wattage card..

If you are going to get that card, the 825w PSU makes more sense and make sure you get the T5500 cable harness with it as that card will need power from the additional 12v rails.

Yea that is way cheaper


The 1080ti draws allot of power yea i might look at something a little bit cheaper and less power hungry
What would u recomend for good 2560×1440p wqhd gaming?

 

[Susquehannock]

That's a great card, however there is one catch, the 1080ti is a high wattage card..

Yes indeed. nVidia lists the 1080ti at 250 watts. You would be pushing it trying to power with the Dell unit's single 18 amp rail in my opinion.

As for the 6-pin on 525w unit. My concern was not so much power available but connectors. Some that are using older cards may require more than one. Have a 560ti (170w card) in my second box. Two 6-pin connectors needed. Using Dell PSU meant connecting the only 6-pin, then 4-pin molex to 6-pin adapter for the other. Made me cringe since that is recipe for 'magic smoke' but it was all I could do at the time. Only ran a few tests and watched that single 12 volt wire on the second connector closely.

 

[Retrorockit]

The GTX 1070 sneaks in at 150W and should be OK on the 525W PSU with a 6 to 8 pin adaptor. IDK if it can do what you want or not, but it's probably as good as it gets w/o a PSU upgrade.
Lex is right about UEFI and various vendors. Zotac and PNY tend to be Legacy and MSI has worked for me with their recent cards but some older ones had issues.
You could go to userbenchmark.com and see what cards others have had success with.

I would say if you can get a 1080ti for a good deal, grab that 875w PSU with it and have fun. That combo will provide a great gaming experience at 1440p and for a few years yet to come!

Not to be hating on the 875w unit. You might consider a new one like this for about same price as those used ones. If only powering one CPU and graphics card, and not a lot of accessories, 600w should be more than adequate.

Be that as it may ... typing this from box #2 now. Plugging away with the EVGA 750w installed. Ran FurMark for over two hours just to stress things. All good thus far. Only issue with install was the retaining tabs as shown in post #576. The 8-pin CPU connector is bulky and a tight fit with the front fan assembly. And I sure would like to cut about 15 inches of wire from this 24-pin connector. One nice thing about the proprietary harness. Only long as it need be for the application.

[edit]
Found that same EVGA 600w from two suppliers at under $33 with rebate. Offer ends tomorrow.

Yea i know what u mean the aftermarket psu are more relible cause they are newer ill take a look tnx for sharing

Seriously considering one of those for myself. The B series are not top of the line but decent. And a deal at $33. Trying to figure out what form the rebate comes in. If they mail a check I am there.

That as long as the rebate is easy to get back. Still though, I have a lot of confidence in Dell's PSUs, even the used ones. Dell's quality controls are very strict and demanding resulting in them remaining solid for many years. Never had one fail on me and have rarely had to replace them in client machines. Additionally, I've bought from that seller and they are very professional and I recommended that 875W PSU with confidence from them. Still it's up to @rock.

yea im gonna keep looking see whats best for me

I am a newbie to this forum and to Dell Workstations. I have worked on and own several Optiplex's, but a couple of weeks ago I acquired my first T5500, a dual X5675 system with 24GB of ram and 2x 500GB HDDs. It has the 875W psu. I have added a 1TB ssd and some fans and a fan controller. The cpu on the motherboard has the upgraded mini tower cooler.

I am running into a problem that may seem a bit strange. Once I am finished setting up the system, it will live in my living room, running headless next to my router/cable modem. And there is the rub. In testing the system is running fine, but a little loud. I installed Speedfan, with the Dell optiuon enabled, and that has helped somewhat, but the fans are not very responsive. They seem to be either on very low or very high. Not much of a happy medium. So I was thinking about moving it all to a new case with better ventilation.

However this presents a problem. The mobo is a reversed (upside down) ATX form factor (maybe a little wider than it should be), so when I mount it in the new case I am worried about the riser card for the 2nd cpu. Am I right to be worried? Is the riser card secure hanging from the top of the board, if I reverse the board to fit a full or mid tower case?

Or should I just put up with the noise?

I am using the system on a 50% utilization basis, long term, as a Chess server. The temps are very good so far, so I may try for more utilization, if I could get it up to 80% I would be ecstatic. But I believe the noise of the fans in the current case would be too loud to support that level. The usage of the system will basically be at a constant level for long periods, as Chess positions are deeply analyzed.

Any help or advice would be appreciated. Thanks!

soo i was doing some benchmarks today and noticed that my ssd score was lower because its using sata 2.0.

i know that the t3500 does not have a sata 3.0 slot so how can i upgrade to sata 3.0?

im using the ssd for booting and a few games.

 

[king of swag187]

It shouldn't realistically matter, but a SATA card would solve that, not sure if you will loose being able to boot off it however

In real world practical usage, you're not going to feel a difference. However, if you want to..

..make sure you get a PCIE Sata card with a boot rom on board.

I wasn't able to boot from multiple PCI-e card on my T3500. Even if the adapter BIOS code was recognized (it would appear on the screen), that controller it would NOT see the attached SSD's in BIOS. This was true for three different cards with ASMEDIA ASM1061 chip.
Funny, if I was booting from other device, once Windows was up and running, with drivers active, devices connected to the adapter would be seen.
More, I have replaced the Motherboard with a T5500 one and I had almost the same results.
Eventually I found a controller that seemed to work, with Marvell 88SE9235 chipset:
https://www.ebay.com/itm/PCIe-x2-longer-slot-SATA-III-4-port-PCI-e-Ver-2-V2-0/273596717064
However, that came with a power filtering capacitor un-soldered from board (in was rolling in the box) and it was unstable, so I return it. After all that trying I decided to splurge $500 on a Dell T7610 with two CPU and native SATA3, USB3.

de difference between 2.0 and 3.0 isnt allot right?

 

[king of swag187]

Its around double, but you shouldn't see the difference IRL unless you're constantly moving around files anyways

 

[SoNic67]

Is not double in reality... My SSD's speed tests for SSD (and not only) are posted here to compare SATA2 with SATA3:
