I'm not really sure what component inside the PSU caused this, the rear on/off switch was just a guess as I couldn't see any damage inside the PSU, also tested the PSU with a different Power cable & PSU tester which I received this morning but sadly nothing, I found it a bit odd that a PSU would just shut down watching a movie IMO :s

any ideas of what component inside the PSU could cause this? as I have never had problems this bad with any of my PSU's, here are some Pictures I've taken which show the inside the PSU:

If there is no sign of damage, it could be because the fuse blew up before anything else did. You could test the fuse with a multimeter to see if it is open. If it is, you could replace it with one that has slightly higher rating and see if something else blows up.

If you do not know how to use a multimeter to verify this, you likely shouldn't be messing with this. If you do proceed with the fuse substitution, I recommend closing the PSU in case something fails catastrophically... you don't want a capacitor metal can to launch and find its way into your eye or something else of the sort.

Ok thanks I'll order a multimeter to check the PSU: http://www.ebay.co.uk/itm/Digital-Voltmeter-Ammeter-Multimeter-AC-DC-Meter-OHM-/160858373320?pt=UK_BOI_Electrical_Test_Measurement_Equipment_ET&hash=item2573e7fcc8#ht_2934wt_1271 , If it does happen to be the fuse I will just purchase one with a Higher rating as you suggested.

Also yeah thanks I will bear in mind to keep the PSU Closed when testing it & I will also make sure to wear some safety goggles to protect my eyes.
 

Don't overdo it too much if you replace it. I would aim somewhere between 1A and 2A above the original fuse. Should be enough to survive inrush and minor events that may have blown the original fuse while still providing roughly the same degree of protection as the original fuse. If this still blows then you know there may be bigger issues with the PSU.

Ok thanks I'll bear in mind to go between 1A and 2A above the original Fuse.
 


@clutchc

Ok thanks for that info, I'll see if I can get the original size fuse in a time-delay version
 
Congrats on your PSU repair 😛

Hopefully the fuse giving up prematurely was the only problem.

I replaced fuses in two PSUs up to this day. One worked perfectly fine, the other vaporized a few components' leads with a moderately loud AC arc buzz sound and light show for a second or two before the fuse burned out enough to extinguish the arc.
 



@clutchc

thank you :)

I ordered a PSU tester from ebay: http://www.ebay.co.uk/itm/280874605587?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649#ht_3132wt_1424 on 08/08/12 & received on 11/08/12, will test the PSU with the tester



 


@InvlaidError

thank you :)

yeah hopefully the fuse giving up was the only problem 😛, I have tested the PSU with a PSU tester which I picked up on ebay: ebay:http://www.ebay.co.uk/itm/280874605587?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649#ht_3132wt_1424 on 08/08/12 & recieved on 11/08/12 & everything seems to be working fine :)
 
Hi Guys

I know this is off topic, but now that I'm feeling happy because that PSU is fixed :), could I have some opinions?, I did a recent case Mod on an Atrix 9001 mid tower, I have replaced both the Top & side Mesh grills with clear plexiglass windows as I think it looks better, could any of you Guys give your opinions on my recent case mod?

http://postimage.org/gallery/1052o4si/afd95fea/

Atrix 9001 has nothing to do with the PC Build BTW, its just a recent mod I did on an older case I have.

thanks :)

 
I would not buy refurbished anything for any PC. You should have gone for a Corsair CX 430 v2 or a Seasonic S12II 380B. FSP/Hexa is poor quality. I'd also consider replacing the case. Its an old design and won't have much air circulating through it.
 


OK thanks , I Know ideally I should have gone for something like corsair or seasonic but I just bought the FSP hexa 500W as I felt for £20 refurbished it was pretty much the best value for money PSU, also I was on a budget & it wasn't really refurbished as it was a pull from a machine which a customer had returned under ?? week return period & the PSU was almost new ( they just had to sell all the parts in the machine & replace it with new because they had techinally bieng used for a few weeks), for my two personal rigs I am using an XFX 550W core Edition (intel core 2 quad q8300 Rig) & XFX 750W Core edition (intel core i7 960 Rig): See my Configuration(s) link

also the case are you reffering to the Atrix 9001?, if so that case is Just an older case I have, the case I used for the pentium G620 Build is a: Ezcool NA-705B

that Atrix 9001 has nothing to do with the PC Build BTW, its just a recent mod I did on an older case I have.
 


Either case isn't that good. Both are rather flimsy and not something I'd like to have parts live in.
 


its a PC I built for a Family member (not my rig) & it was also a budget PC build but then again Im not using that case
 
I think you did a fine job on the Atrix. Looks really nice. But I imagine air flow is going to be limited since you replaced the mesh grills with plexi-glass. I only noticed one fan at the rear... and an empty mounting opening for a larger one. Living in the US, I'm not familiar with the Atrix brand. But it looks alot like a Lian-Li case I once had.
 
@clutchc

Thanks :)

yeah I was thinking that when taking the mesh grills off about the airflow, but I think it looks better with the window(s), this case has space for front 120mm, Rear 120mm, Top 80mm fan & used to be able to put a fan on the mesh side grill window (any size) because it used a plastic skeleton type structure to mount the fans on.

Also I think Atrix 9001 is Made by ColorsIT (CIT): http://hardwarelogic.com/articles.php?id=5204& yeah i think it reminds me of an Lan-Li case a bit
