Hi all
I’m upgrading a redundant PC I was gifted at work to do some light gaming. It’s a Lenovo Thinkcentre M91 tower with i5-2400; 4 x 4 GB DIMM and a couple of SSD drives. The existing Radeon 6670 GPU is obviously not suitable for gaming, so I’ve purchased a Sapphire R9 380 compact card and matching (I thought) Corsair CX500.
Before adding the new GPU I replaced the PSU, however no luck getting the PC to power up. I swapped back the original PSU, and no power now either. Stripping out all components and leaving just the m/b and CPU plugged in does not work, however both PSU’s power up briefly if I leave the CPU unplugged, and only the 24 pin plug in.
Some horror stories on Amazon suggests CX500 units have in the past fried components, though the vast majority of people seem to be happy. The CX range is on the “only buy if you really have to” list on Tom’s, but gets a good review here - http://www.tomshardware.co.uk/power-supply-review-80-plus-bronze,review-32766-4.html?
Any suggestions on what to do next? E.g. is there a way to figure out whether CPU, motherboard or both needs replacing without replacing something that works?
Cheers!
