Works fine
It makes my computer power on, hasn’t failed yet and is cheap. No problems so far.

Fixing screw holes too small
Bought this PSU to replace the one in my SFF Optiplex 9010 which had failed. Physically it fitted OK into the space but I couldn't use the 3 fixing screws from the old (Dell) PSU to secure it because the threaded holes in the new PSU were a smaller thread. Until I can find some smaller screws I've had to leave it unsecured in the PC case (although it clips into place which holds it pretty well). Otherwise everything OK & my PC is operational again.

Got us out of a mess
Our computer turned itself off on Wednesday, diagnosed it to be a faulty power supply, and ordered this on the afternoon to arrive by 1pm next day. It arrived at 11am, 2 hours early and by 1pm the computer was working again. Can't faulty the item or service.

Working great for now
Previous PSU popped and smoked, so got his as a replacement. Arrived very quickly and well packaged! Working perfectly so far, being used a few hours each day. Will update this if anything goes wrong with it.

Awful piece of equipment
This item was purchased and placed into a machine which it promptly BROKE. I am now trying to seek the cost of the £180 machine from amazon who have advised me that I need to go directly to the seller to claim it. So I will be doing just that. DO NOT BUY THIS ITEM

money well spent
i managed it fairly easily, however, i do advize you check out the youtube video so as not to make any mistakes, ive never done anything like this before, but its working perfectly, and i feel really chuffed with myself, you dont have to be a tech person, but watching a video first definately does help..

Had to replace the supply on an older Optiplex 7010 and this was an exact fit and all the right cables. It’s a small form factor tower which is a pain but Dell make it’s easy to do the swap. Only thing was the screw holes didn’t line up exactly 100%, but it’s immaterial. The threading was also different than the OEM so the old screws are tighter to mount. There’s 3 so it’s no big deal. Had it swapped out in about 15 minutes.
