I have a Dell Inspiron 545 mini desktop tower, for which I need a power supply. The current power supply is a delta electronics PSU with 300w of power and has a dimension of 6" Wide X 3.5" Tall X 5.5" Deep. There is a little more space for the dept like instead of 5.5 the maximum I can have is 5.8 of dept and another 2 inches max for the height. That is all there is no more space for a bigger power supply.
Can I buy a good quality power supply within these dimensions with a 80 plus bronze or gold rating, modular cabling if possible and between the range of 360w to 450w. Is this possible. Please let me know as soon as possible as my current power supply is really running out of juice.

Thank You.

Specified dimensions 150 × 86 × 140 mm (5.9 × 3.4 × 5.5 in) are standard ATX size. However, majority of available PSU has more than 140mm in depth.
If you want modular 140mm PSU, then Silverstone ST50F-P, ST55-G are probably the best choice. If you want less wattage, check SFX PSUs from Silverstone (ST45SF(-G)). They ship with ATX bracket included.

Thank You very much. Looks like this will work. I shall look in to this.

The Silver stone site says the dimension for ST55F-G is 150 mm (W) x 86 mm (H) x 140 mm (D). But I went to amazon.com and there the dimension for ST55F-G is Size (LWH): 12.5 inches, 8 inches, 4 inches. Why is this so. Please let me know as soon as possible. Thank You.

I guess it's a size of the box it ships in. Not the size of the unit itself.

A good review:
http://www.computerbase.de/artikel/netzteile/2013/be-qu...

You asked about fully modular PSUs, that's why I suggested Silverstone. BQ system power 7 units are not modular. Other things I don't like about this series is the dual 12v rail design and lower efficiency than ST55-G (at least on paper, linked review confirms that it meets 80+ silver).

If you can fit non-modular 140mm deep PSU and can balance the load between two rails, then System Power 7 series is worth considering. In this case, also have a look at Enermax Naxn series.

Personally I don't like Be Quiet PSUs. Two of them - Straightpower and dark power pro failed on me just after their warranties. Thus, I don't recommend them to anyone.

Silverstone Strider Plus Gold 550W is small and modular. Smaller than that is the Nexus NX5000v1 550W but it is not modular.

First hit from google:
http://www.jonnyguru.com/modules.php?name=NDReviews&op=...

Reading higher wattage model reviews gives you overall impression of the PSU series. Manufacturers tend to keep the same internal design across all models in series. Usually only some components are changed to cope with higher amperage, and the rest of the PSU is similar, so is the build quality.

They reviewed 650W version. You can get general image of this PSU series from it. Actually 550W model is better in terms of efficiency.

You need to decide whether you want the psu or not,no number of reviews will make you want it. Just know that all your other options are not modular. For instance, FSP Aurum 500W is 140mm

Do power supplies with modular cabling perform better or is it just the advantage of being able to detach unused cords and replacing the non working cords.

Just the possibility to attach the needed cables only.
PSU being modular has no influence on its performance.

Modularity has no effect on performance except perhaps in a small case where cable clutter might influence airflow.

I was reading through the review of ST55F-G on jonnyguru.com till I reached the dis-assembly page where the filtering stage was displayed. The components are not named over there. So to make sure can you please go to this link http://www.jonnyguru.com/modules.php?name=NDReviews&op=... and check if the ST55F-G has a metal oxide varistor or MOV also the color of the MOV please, whether it has 2 ferrite coils for the transcent filtering stage and how many transformers does the ST55F-G have. Please let me know as soon as possible.

Thank You.

Yes, it has a MOV. It's yellow, next to the coil under X capacitor (green). It has one ferrite coil in the transient filtering stage. All this can be seen in the 5th image.

In all the images, I can see two transformers: main (bigger one) and +5VSB (smaller one). Possibly there are some optocouplers somewhere on the board, serving as isolators, instead of the third transformer.

I see 3 transformers in the 5th image one transformer is behind the big capacitor on the left and one more the smallest one next to the X capacitor green on the right . There is also the 3rd image which is showing the transient filtering stage. I see one more coil over there too. Is that a ferrite coil to. Correct me if I am wrong.

Yes, there is one more coil just after AC input, I somehow missed this image. I'm not sure about that third transformer, there is no clear shot of this component. You are probably right, tough. From the electrical viewpoint this should be another transformer.

For the ST55F-G I will need an adapter to be able to connect the main power cord to the main grid. Will this affect power supply performance.

You mean different power plug type? No it won't affect the performance.

Apart from internal components, performance depends on input voltage and frequency. Generally, the higher they are, the more efficient PSU will be.

It is a individual plug which will be attached between the mains socket and the power supply power cord. The plug says it is 5A/10A 250V~. Will this work with the ST55F-G power cord.

Hi! I am back. The computer that I was on needs the PSU and the PSU fan broke down which led to over heating of PSU amd MOBO and PC crashed but managed to restart and transfer all book marks and passwords to another PC.

I found a review of the Silverstone ST65F-G on jonnyguru.com. Over there the dis assembly stage has many nice clean and detailed shots. The only thing is the parts are not labeled. Can you please go to this link http://www.jonnyguru.com/modules.php?name=NDReviews&op=... here and check if it has all 3 transformers and a NTC thermistor, the color of the thermistor as well please by looking at the 7th image. Thank You very much.

Black, next to the primary capacitor. It's a MF72-6D13 NTC thermistor. It normally would be green, but colors all are mixed up on this platform.

In terms of efficiency Antec EarthWatts Platinum units are probably the best. Unfortunately they use some cheap components, that's why I don't recommend them. My choice would be simple. Seasonic s12g if non-modular, Silverstone Strider otherwise.

FSP platform used in Aurum series is also very good. Even some higher end platinum models are based on it's variations.

For max wattage the FSP Aurum 700W or Sesaonic S12G 750W
http://www.tweaktown.com/reviews/4137/fsp_aurum_gold_au...
http://www.kitguru.net/tag/seasonic-s12g-750w-review/
For absolute most shallow Gold ATX PSU Nexus 550w
http://www.quietpc.com/nx-5000v1
The antec earthwatts platinum has very few connectors (earthwatts is a budget line) hence the efficiency can't really be exploited to the max
Other than those,you're talking 80 plus Silver or Bronze,like the XFX mentioned above or Silverstone Strider Plus 600w.

What? EA-550W platinum has exact same connectors as FSP AU-500W and it's higher efficiency can be exploited over all load levels...

There are no fully professional reviews of AU-500. Have a look at 700W, 400W and 500W units. They all share the same platform, but some components are different. Overall it looks like simple construction, compared to Strider.
