Dell OptiPlex GX520 SFF - no power indicator

• Power supply Dell Optiplex 790 SFF cycles power on and off when it is plugged

  My new to me SFF Optiplex 790 does not start - pressing power causes a switch to send amber for a few seconds, the 1 + 2 diagnostic lights shine briefly, and then the system turns off. But wait... with power plugged in, it will try to restart every 10 seconds or until I have unplug the unit.

  System lasted about 30-40 minutes when I tested it, but it starts then power cycling.

  Power supply passes with built-in 'green light' regardless of any internal or external devices connected. I bought a sweater 'work' PSU, no change.

  Ideas for testing? System is stock, no mods or upgrades of what I see.

• Add the second hard drive in the Dell Optiplex 780 SFF

  Hello

  I have dell Optiplex 780 SFF (Small Form Factor) PC. It has 3 options of SATA. I want to add 2nd hard drive in it, but I see no power for 2 hard drive cable.

  At the present time, I have a SATA Hard Drive and a SATA Super Combo. But the power cable from the SATA Super combo is very unique, I can not able to give the power of this cable to my 2nd hard drive.

  Is it possible to add 2 hard disk in the PC case?

  Best regards

  Dani

  Hi Dani,

  The SFF is using a drive slim lens that does not have a standard SATA power connection. You will need to buy an adapter or a SATA power cable splitter to power a second hard drive.

• Need a video card compatible for Dell Optiplex 745 (SFF) - help, please!

  I have a Dell Optiplex 745 SFF. The details of the standard can be found here: http://www.dell.com/downloads/global/products/optix/en/opti_745techspecs.pdf

  (even once, look at the MFS)

  I want to get the best possible video card for this PC that I can find, and I was hoping someone could help me with my options. I am aware of my options are limited, but I'd like to work with what I have here. Thanks much for any help.

  Sapphire 7750 is the best low profile card I know. There is no need of current auxiliary and is compatible with your power supply.

  SA makes a 7750 as well, but it requires more space and I don't know if it is compatible with your frame.

  No, the OptiPlex 745 LTS has a Dell exclusive power and cannot replace it with a larger unit with more power, they are has no third-party power supplies available.

• Dell OptiPlex 755 SFF rear disc HARD fan Press F1 CORRECTED an error!

  EDIT: Fix for F1 error is on the #2 post. Try only if you know what you are doing and don't mind not having is not a HDD stupid fan. I now only use a SSD and it needs no power noisy fan to waste.

  ORIGINAL MESSAGE:

  I removed the fan hard drive dying on the Dell Optiplex 755 SFF (fan is built in a hdd cage) and modded the side of the case to include a Yate Loon 120 mm fan. I removed the hard drive in its entirety and then used cage the where the floppy drive has been to place my SSD 256 GB of free space. The system is much more pleasant that way, and now he has place for 120mm fan (already modded).

  However, at startup, there is a rear fan error and it asks you to press F1 to continue. It disappears when I connect the old dying noisy fan (has more room for it). Because I don't want the hard drive cage (or his fan also) and I can not put the fan back in, I want to use the connector and the son of the old fan dead and hang it in my nice new Yate Loon, which is the ideal solution for cooling (used as a suction fan).

  The color codes are:

  Yate Loon (D12SL-12): Red = 12v, black = mass, yellow = Tach (I think)

  Dell drive HARD fan (STROKE BN06015B12H): Red = 12v, black = mass, yellow? Blue? (PWM or tachometer)

  What are the blue and yellow for the Dell HARD drive fan? Can I just plug the Red of Dells Yates red and black wire on black? This should give me a 12v fan work, however I wonder if the loons Yate flying over red wire could be used for the sensor.

  Any help would be great. Really sad that Dell did not include a fan setting ignore in the bios.

  Thank you!

  SkOrPn

  EDIT: Ok, Yate Loon do not light up when it is connected to the fan header. What is missing? The old fan of Dell is rated 12v A 0.36 and the YL is 12v 0.30 A, less than the old fan so the fan header would seem like the logical place to get needed power as it provides much. When the old fan is plugged it provides 12v, but does not provide power when Miss the blue and yellow wires?

  Edit2: Ok, understood as the Yate Loon uses the Red wire as the 12v fan (somehow, I thought it was yellow). Now, I think that the yellow must be a son of tachometer for rpm. Now I'm wondering if the Dell system can monitor the number of TOWERS to connect the yellow wire without prejudice to the system without the connected blue. In fact, I wonder if the controller monitors just RPM to warn of the fan failure. If so, maybe I can connect the yellow and get rid of this error from the BIOS at startup screen.

  Hello

  I've linked yellow pine of wire of the connector of the fan HARD drive on yellow pine of the CPU fan connector and no fan of F1 more at startup error -correction

  I have no need for my SSD disk drive hard noisy fan.

  

  

• Windows XP 64 bit will run on a Dell Optiplex 780 SFF or Optiplex 980 SFF?

  I intend to buy a Dell Optiplex 780 SFF or a Dell Optiplex 980 SFF, but I would like to know which one will work with Windows XP 64-bit.

  For Windows XP 64 Bit its better to use the somewhat hidden (old ftp site):

  http://FTP.Dell.com/Browse_For_Drivers/desktops/OptiPlex/OptiPlex%20780/

  http://FTP.Dell.com/Browse_For_Drivers/desktops/OptiPlex/OptiPlex%20790/

  http://FTP.Dell.com/Browse_For_Drivers/desktops/OptiPlex/OptiPlex%20980/

  This has the old drivers listed in multiple versions, including XP x 64 drivers not mentioned on drivers and downloads. The new ftp site is currently slightly broken.

• Dell Optiplex 755 SFF - How: maximum performance?

  Reference Dell dear users.

  I have a Dell Optiplex 755 SFF, and I would change all my materials for the best components that I can use.

  Is it possible to upgrade my processor Q6600 to a Q9550 / Q9650?

  I know there is no Q9550/Q9650 on the compatibility list, but I saw someone put the CPU into this motherboard, and he said that he works very well with this motherboard. So, what is your suggestion? I would like to give it a try? Will it work? Or is it just a complete?

  Is it possible to put a primary HARD drive and a secondary SSD in the system?

  If this is the case, what is your suggestions? I thought about a 120 GB SSD system and a 1 TB Western Digital HARD drive, it's a good combination? (7200 RPM, SATA)

  Who is the STRONGEST Videocard for its price, which can adapt to this mobo?

  Many people say LP 7750 HD is the best of what you can get, but I checked ebay and other Web sites, even sought a 7750 HD LP "pre-owned", but I could not find. What video card do you offer me?

  ((Current))

  Q6600

  RAM 2 GB (1x2Go)

  INTEL GMA3100 (: C)

  150 GB HARD DRIVE

  PSU 275W

  Thank you!

  7750 (now called profile low 250 R7) uses more than 25W you run the risk of damaging your system.

  Low Profile Fanless Silent ASUS EAH6450 to 27W is the max I would use.

• Dell Optiplex GX520 Memory Upgrade

  Hello, I install 4 GB of memory on Dell Optiplex GX520.

  Of memory can what type I install?

  PC2-4200 is not fast enough for some of the processors supported FSB.

  Faster RAM doesn't hurt anything, but it may not work at the fastest speed, unless the processor is running at top speed for the FSB also.

  • PC2-4200 = 533 MHz clock
  • PC2-5300 = 667 MHz clock
  • PC2-6400 = 800 MHz clock

  

• Card PCI-E graphic for Dell Optiplex 755 SFF

  Hi all

  I have an Optiplex 755 SFF 275W PSU and PCI-E video slim with.  Graphics on this series are awful - video DVD playback cannot without jerking.  I spent a few hours trolling on the web trying to determine which video card will work in the 755.  The general consensus of the 'guaranteed' card is the Radeon HD 2400 PRO.  So, I managed to follow a fact (after trying a 5570 & it not even leave the PC start), had shipped here and installed.  To see that it does not too leave the PC startup.  So typical of Dell to make the PC which are incredibly limited.  What is the point of having a PC capable of running Win 7 (will have 8 GB of DDR2 RAM, has currently of 2 GB and currently has a Dual E6550 - core 2.3 Ghz CPU) when he cannot take a card even modestly spec'd?  This is the last time that I buy Dell.

  Anyway, having spent the mug shot (ah, much better, thank you)-why the this junky 755 will only take the so-called "guaranteed" HD 2400 PRO?  When I try to start it up, it not this stupid pre-start high ramp / down fans, then turns off, try again, then turns off, then on the 3rd go fans just go hard on & stay like that for as long as I care to leave.  If I take the HD 2400 PRO on & put this stupid DVI adapter card in the PCI-E slot, it's all good.

  No changes have been made to the 755 - it's just a standard stock machine.  If for some bizarre reason, all others using the HD 2400 PRO with the 755 SFF tell bald-faced lies (that is, they are not really using a HD 2400 PRO at all), what are the other maps?  I see that the motherboard has "25W" appear next to the slot PCI - E - but the HD 2400 PRO is rated at 25 w max.

  Buy the 755 was supposed to be an inexpensive way to make a living desktop PC.  I don't want to lose more money on cards that don't work.  And the HD 2400 PRO was relatively expensive for such an old map, obsolete (crazy NZD$ 42 - when a 5570 is only NZD$ 65).

  Any help / constructive suggestions appreciated.

  You can change. Click the Green pencil. But I already have to remove both blasphemous words.

  The 755 came in four different chassis sizes. You have chosen a smaller with the smallest power so you don't you. Here are valid Dell Low Profile PCI - e 16 X for this chassis - video cards

• Dell Optiplex 755 SFF 2015 video card update

  Dear readers.

  I'll buy my first Dell computer, which is a Dell Optiplex 755 Small Form Factor. It has a Core 2 Quad q6600 CPU in it, with 2 GB of ram and a PSU 275w. I have a Nvidia Geforce GT220 video card, which is a low profile video card, it can consume the maximum of 58 W, and this video card requires at least 300 W works without problems. Will it work with this diet?

  Link to the video card:

  Thank you!

  I'll buy an Ati Radeon HD 2400 XT, because im does not intend to do some games 'hardcore' and other animals, it can be good for my needs.

  The 2400XT is very outdated and terribly weak power. You are much better with people like a Sapphire 6450, that can be done for $43 postpaid from Newegg.

  What is the «largest "graphics card I use in the Dell 755?»

  Thanx

  Huh

  No such model card works with all THE SIZES.

  MOST of the cards DO NOT MATCH and will NOT WORK.

  The slot is only 1 large map.

  Feeding is 305 w or LESS depending on the size.

  the 755 isn't a game system.

  75W max card and ONLY with Mini lathe.

  Best map of single slot for Tower is a GT740.

• Old Del Optiplex 755 SFF

  I am considering the merits of upgrading the HARD drive in my old 755 SFF pc with 1 TB SATA one. New HARD drive works ok on xp pro.

  I have old legacy applications of VB that must be changed and the need for the room.

  Drives up to 2 TB will work very well.  You need to set Sata operation RAID ATA instead of AHCI or xp will start installation then crash with STOP 0x0000007b inaccessible boot device.

• More big power supply for Dell Optiplex 7040MT - please help

  Hi all

  I recently bought a dell optiplex 7040 mini lathe and it came with a 240 watt power supply. I want to update and would like to know what my options are.

  Thank you

  The 7040 could use the same wacky scheme that uses precision T1700.  If this is the case MODDIY has an adapter to convert the 24pin connector 8 pin. Suitable for Dell OptiPlex 3020 / 7020 / 9020 / T1700 so I think the 7040 is the same.
