Issues with the PSU of an HTPC based on AOpen HT80D box

Hi
A couple of years ago I bought an HTPC to Forcet Computers (Forcet does not exist anymore) This HTPC is based on AOpen HT80D box. It was working ok for more than a year but it began to crash after no more than half an hour working. Windows event viewer messages shows an unexpected Kernel Power issue. The HTPC has a GigaBit motherboard (intel i3 processor) , a Bluray device , and a low profile ATI Radeon HD5450 graphics card with a passive cooling system.
This box includes a 275 W silent PSU (even though AMD recommends 400 W or more for its graphics card). For the crashes initially I thought of an overheating issue with the graphics card, but after doing testing with another card which includes a fan I discarded that. Now everything points to PSU failure, even though its fan seems to work. After half an hour or less the HTPC crashes, but then reboots again after an hour or maybe less (notice that system clock has frozen since crash).
How could I test (no using another PSU of course) if this is a PSU issue?
I think I could change the PSU, but I don't know whether Aopen sells it separately or not, so does anyone know of another PSU same size (small) to replace the original one?

Thanks in advance for your help.
