Question about Enhance Technology SFX-1211J, Enhance 110W 1211J Power Supply (SFX1211J) Power Supply

2 Answers

Enhance Power Supply only works unconnected to computer

I have an enhance sfx1211j power supply that had a bad fan and swollen output filter capacitors. Even in this condition the PS was producing voltages as the computer was still running. I replaced the fan and the filter caps and now the PS won't power up the computer. The PS DOES turn on unconnected to the computer when you ground the green wire and seems to have all the proper voltages. I verified this by comparing its voltges to that of a brand new unit wire by wire. Even the levels of AC ripple are the same. The new unit does power up the computer. How can this be?

How to increase power on my daystate mk3


Basic power supplies should be 400 to 1000 Watts for current systems. A 230W supply is Underpowered and may not support the hardware devices all that well. In addition, the Video drains power, so a Video card with 2G Ram will help speed up the process. Then an additional Power RAM (Memory) with speed available to your system; helps increase activity. Cooling Fans help reduce HEAT that also slow down operations. Clean the inside of the computer as dirt., dust and dust balls collect and keep the electronics hot.

The only thing to do at this point is to replace the Power Supply with a KNOWN to be good, compatible unit, and see if the rest of the computer hardware components are okay.

Going by your information stated that the Power Supply is an Enhance ENP-2224B SMPS, (Switched-Mode Power Supply), it is a special shape.

If it wasn't for the Slim Micro-ATX computer case you have, you could use an easy to obtain ATX form factor Power Supply.

From a quick search though it looks like a replacement unit is affordable,

There is simply no way to tell if the motherboard, and/or Processor, and/or Ram Memory, and/or Harddrive, etc., is okay without having power.
Unless you transfer the components on the motherboard to another working motherboard.

[NOTE*
If your Power Supply has a rocker switch on the back that lets you use 120 volts, or 220 volts, make SURE it is set to the right voltage.

USA?
120 Volts
Europe?
220 Volts
Australia?
220 Volts
Japan?
100 Volts ]

Then your power supply is dead. You can purchase a new power supply relatively cheap. Give newegg.com a try.

Why shud i use a 230W supply on om my XBOX 360? is it better than the 175W and the 150W?


The more amperage you have on the 12 volt rails the more power you can draw from the power supply. For an xbox 360 I don't see any reason why you would use a non-standard power supply unit there really is no gain using a computer PSU on an xbox 360 unless you broke your factory PSU and then you could rig a computer PSU to it but your better off not trying unless your really good at electronics.

SFX-1211J no -5vdc


The -5 V requirement for ATX supplies was dropped after V1.3. It was used primarily for the old legacy ISA slots - though not exclusively. If you test any contemporary supply made in the last few years if will show a -5 V failure because it just ain't there! Unless you had a really old MB, the supply is probably fine. Look at the 20 or 24 pin MB connector and if there is no line where the -5 would be ( pin 18 ) then you have no problem.
