What type of PSU do I have?

I have the dell inspiron 530s. From a range of websites I have found out that the 250w rating of the power supply is for continuous output, but I'm not sure about the peak or type of power supply.
 
It looks a bit special sized, like a TFX unit.

What do you need to know?
1) Do you need to replace a defective unit?
2) Are you contemplating upgrading to a strong video card?
3) Other reasons?

number 2. my case and power supply are really limiting my options for video cards. I have to go for low profile and low power cards. that 300w power supply doesn't seem like much of an upgrade. I was looking at some case and power supply combo deals but I'm not sure if my current motherboard will work with them.
 
If your motherboard has a pci-e x16 slot, you can probably use any graphics card that does not need an6 pin pci-e connector. This might be as good as a 5570.

If you have a spare 5 1/2 drive bay, there are auxiliary psu's that will drive any single card.

Unless your motherboard is a BTX type, you can probably use it in any case.
If you get a new case, it would be better to use a conventional psu instead of the aux addition.
 
That Seasonic PSU was tested up to 345W. You wouldn't want to run it flat out like that, but you'd have no problem with a HD5570. Only the size of your case prevents you from putting a HD5750 in there.

yeh i was looking at the 5570, gt240 low profile and the 9600gt low profile. i could wait a few months for the new nvidia cards aswell but i doubt they will be low profile. couldn't the 5570 work on my current psu? therefore i wouldnt need a new psu, unless i want to go for the gts250.

they do recommend it but the 5570 has a max power draw of 42w. the current gpu im using, hd2400 pro, has a max power draw of 25w. ive overclocked my current gpu aswell but i have no problems with it.

the low profile gt240 i found has a minimum power supply requirement of 250w and i think it uses more power then the 5570.
 
You should post a pic with that sticker like this

The +12V is important, how many Amps do you have? Also below that "ЯU" logo it's written LEVEL3 E239511. If you have something like that written on yours tell us what's the number after the E.

 


Sorry about that, it was something else when I posted that, anyway you found the thing.

Found this:

http://en.wikipedia.org/wiki/Dell_Inspiron#Inspiron_530s

Your mobo is this one?

http://www.newegg.com/product/product.aspx?item=N82E16813186125

If yes, it's a standard mATX mobo and I suggest changing the case/PSU and get a good video card so you can use them on your next PC as well. You can get a good PSU and case for under $100. The case should be ATX so you can use it on your next build if you go with an ATX mobo. I think investing in a weak video card (if you're gaming) isn't worth it.

im not sure if thats the exact 1. the picture shows a pink plug and a green plug at the back with the old keyboard and mouse plugs. i dont have these, i just have the blue plug. this could be because its not the exact motherboard that it says on the wikipedia page. either way i guess it does mean the power supply is mATX. so will a ATX power supply and case work with the motherboard or do i have to find a mATX psu?

well i have found out that AFX power supplies will work with mAFX motherboards. I've been looking around and found a few that look good. I decided to go with a case and psu combo.

heres 1 with a coolermaster case and 620w psu (which isnt by coolermaster). Link

This 1 is a bit more expensive but also has a coolermaster case with a coolermaster 460w psu. i can buy this coolermaster psu separately for £35 but as a combo its a good deal. link

heres 1 with a coolermaster case and a coolermaster 700w psu bundle. pretty cheap but the box is damaged.
link

heres 1 with a weird looking case and a 650w psu. doesn't give much details about the psu really. link

I have also found this arctic power 700w PSU that is pretty cheap which i can put into any case. link

This corsair 400w power supply looks good with 5 year warranty. link

 
That Corsair PSU is high quality. Coolermaster Silent Pro also reviewed very well; the older Coolermasters are overrated junk.
I can't tell on the others, but I'd be careful. The PSU is not the place to cut corners.
In your place, I'd go for the damaged box case+PSU; you can always get another cheap case if that one is too banged-up to use.

just my luck that the coolermaster combo is now out of stock. searching for it seperately, the psu costs twice as much so that was a very good offer. Thanks for the help anyway.

sorry to revive an old thread but now that there is a low profile 5670 I'm torn on a decision. I'm not sure if the 5670 will work on my 250w psu but it will save me alot of money. Its either that or buying a new case, psu and the 5770. the case, psu and 5770 would come up to £170 but the 5670 is around £70. It would also save me alot of time and effort instead of moving the whole system into a new case.
 
Post some pics with the inside of your case, we want to see if a regular ATX PSU would fit.
That Corsair you were looking at is good and it's 5.9"(W) x 3.4"(H) X 5.5"(L); 150mm(W) x 86mm(H) x 140mm(L) according to the Corsair site.

Post a pic with the back of the case too, I want to see the PSU mounting screws.

this is all the information I have about the system atm. has a lot of diagrams that show the motherboard and inside view of the computer. Width-3.9 in, Depth-17.1 in, Height 14.3 in. ill post some pics later

http://support.euro.dell.com/support/edocs/systems/insp530s/en/OM/HTML/parts.htm#wp1484228

edit-just checked and found out the power supply currently in my comp has a TFX form factor but is an ATX psu. the dimensions: 178L x 85.7W x 69.8H mm (7.0" x 3.4" x 2.8"). Efficiency: 65% minimum. DC Outputs (Amps Max/Min): +3.3V (11/0.0A), +5V (18/2.0A), +12V (17/0.0A), -12V (0.3/0.0A), +5VSB (2.0/0.0A)
DC Notes: (1) +5V and +3.3V 120W maximum output.

im not sure if the corsair will fit or not and to reduce the risk when putting the 5670 low profile in there i could get 1 of these 2 TFX psus i found. the seasonic 300w isnt available in the UK btw.

400w psu by EZcool. i registered and checked the price. very cheap only £19.99 link

300w psu by Be Quiet. Description says it has a high level of efficiency up to 86%. over twice the price of the other 1 though. link
 
No, the Corsair would not fit in your case.
If those are your only choices I would trust the Be Quiet model much more than the EZCool. Is active PFC not a requirement in the UK? I doubt the EZCool is capable of outputting what's on it's label, and an efficiency of 65% is dismal, and means a lot of waste heat.

well would you trust the ezcool more then the bestec i currently have? couldnt you work it out through the voltage loads. the ezcool has voltage load: +3.3v 28A; +5V 35A; +12V 24A; -12V 0.8A;+5vsb 2.0A and the Be Quiet has voltage load: +3.3V: 20A • +5V: 22A • +12V1: 14A • +12V2: 16A • -12V: 0.5A • +5Vsb: 2.5A.

the be quiet psu is pretty expensive, i could buy the corsair and a new case for the same price. 1 thing i am worried about when moving the motherboard is the back panel of my dell. its built into the case but I have read that people have screwed it out or have had to use a normal inspiron 530 case which has the same motherboard. other people have said that it mounts perfectly into other cases default I/O panel.
