Corsair HX850 going bad? - Page 2

post #11 of 12
The most practical way to test is by swapping the power supply and memory, but I have a feeling the PSU is fine because it's Corsair, while the memory may be bad because it's Corsair.

The only way to check a power supply is by measuring it with a digital multimeter while it's under a realistic load, like a motherboard (not a handheld power supply tester). The motherboard's own monitoring hardware can't be trusted and often gives widly wrong measurements. For example, I had a motherboard that said the +12V rail alterneted twice a second between 6V and 8V, which was an impossibie because the hard disk was spinning, and it needed +12V +- 5%. Those digital meters that Harbor Freight often has for $3 or free with a coupon are fine for testing this.

Corsair memory can be really bad because it's made from factory reject chips and isn't tested very strictly. So test with either known good memory (Samsung or no-heatsink Crucial), or try just one of those 2GB Corsair modules at a time. Also don't rule out a dirty DIMM socket.

Just a FYI, it was my PSU from what I can tell. I replaced it this morning and it's been running all day without issue. Corsair sent one out right away which was nice.
