Back in June I received an 800watt / 65V Power Supply from NVVV AliExpress store.

Recently I noticed the cooling fan comes on all the time and it heats up internally very quickly, so curious, I opened it up.

What I found was a mess and a product that had been salvaged and I think may even be dangerous to use. See images below.
BRAND NEW UNIT - Paid full price.
Of course, It's out of warranty now so they got away with it clean. Never again.

That is absolutely the worst bodge job I've ever seen, genuinely surprised it works at all. Personally I would at least do the repair again but properly, or cut my losses and get a new PSU from a more reputable source.

The ones I bought from eBay have given no problems. Unfortunately, I could not find the order to tell who the actual vendor was but it was a US vendor.
