Bad psu can damage cpu?

johnspack · Apr 2, 2015

Thought my system was okay after I replaced my psu. But it started rebooting and bluescreening at random again. Used all the parts on my P6T mobo, except my cpu, and it ran flawlessly for weeks. Put everything back in my main system with my Gene II when I got new psu, seemed okay for about a day, then all hell broke loose. So I just swapped in the P6T into my main system, and used the 950. It wouldn't even post. Pulled the 950 and dropped in my xeon, booted right up and is running perfect. This sucks because this xeon is an es and will only hit like 3.8ghz... oh well, it has an unlocked multi... like it matters. Has anyone else experienced a damaged cpu without ocing the hell out of it? And where can I can find decent priced sb-e parts....

Sure can although a quality one should protect the rest of the system, however a cheap one could very well kill any or every part of a system.

johnspack · Apr 2, 2015

It was my Silverstone... too many other peripherals were damaged, it was the culprit. Down to my last x58 mobo which is also on the way out. Must find either a good deal on some sb-e parts, or I'll just cheap out and go haswell mainstream with dual channel crap until I can afford better. Can only push even high quality stuff for so long before it breaks down. Most of my stuff is lost to folding and crunching, which only rich people should do. Stupid of me.....

And does anyone have any gentle... 3.5-3.7ghz settings for an ES W3570 cpu? I remember I could only get max 3.8 out of it stable, but that was a pain, I just need better than the 3.3 at 1.2v im doing.
I'll work on it more tomorrow, but it's a pain.....

Bad PSU can even damage your room... burning to the ground everything...
always look for certified 80+Bronze minimum on "trsuted" brands, such seasonic, XFX, Thermaltake, Enermax, Corsair antec coolermaster, for example...

i dont trust Silverstone,

A bad PSU can destroy anything connected to it, but it is not likely it would destroy the CPU only.

The most common cause for a failed CPU (that used to work) is mishandling by the user.

This is frequently due to ESD - where a static discharge from the user's body scorches a Grand Canyon size (microscopically speaking) gorge through a few million gates on the CPU die - typically without the user ever being aware a static discharge even occurred. This is because a static discharge so tiny it cannot be detected (heard, felt, or seen) by humans easily has the potential to totally destroy very high density ICs like processors and memory chips.

Make sure the power going to your PSU is good. Have the electrical in your home properly wired and grounded. Get a UPS.

Couldn't agree more! Every home and computer user should have access to a AC Outlet Tester to ensure your outlet is properly wired and grounded. I recommend one with a GFCI (ground fault circuit interrupt) indicator as it can be used to test bathroom and kitchen outlets too. These testers can be found for your type and voltage outlet, foreign or domestic, at most home improvement stores, or even the electrical department at Walmart. And if a fault is shown, have it fixed by a qualified electrician.

And IMO, every computer (and expensive big screen TVs and home theater audio systems) should be on a "good" UPS with AVR.

johnspack · Apr 2, 2015

Yes, I should get a UPS. For now though, my xeon is stable on my p6t mobo. So my old psu damaged my g700s mouse, my 64gig flash drive, my 950 cpu, and possibly my whole gene II mobo. Now I just have to try and remember how the hell I oced this dam es xeon to 3.8ghz.....

Not needed if you live in the civilized world.

Joking aside, Silverstone makes OK PSU's. A faulty PSU is a faulty PSU no matter the brand.

Here in Mainland Britain our Power Supply is very stable and for most of us a UPS for home use is generally overkill.
Of Course for Mission critical use ie Business / Home Office ect one should invest in a high Quality UPS ( and write the cost off against Tax ).
Now that brings me on to the subject of Stand by Generators..............................

sure you got that a bad psu can damage your cpu, It can destroy everything in your machine and make it a large paper weigh or door stop. It has a range of volts it has to send out and stay within and anything outside that range can kill hardware in the machine. UPS won't save computer hardware from a bad psu, but it can prevent power surges from in power coming in and keep the voltage consistent to the psu.

Bill_Bright · Apr 2, 2015

It is incorrect to assume because you power is stable that you don't need a good UPS with AVR. MANY anomalies that can damage your computer don't come off the "grid".

And being in a "civilized" world has nothing to do with an outlet or Earth grounding being mis-wired, or damaged.

I couldn't agree more. The previous house I owned I had the outlets tested (after some erratic pc behavior), and they varied widely. Electrician called the power company, because he suspected from further testing the problem started before the house. And yes, I live in the "civilized world" (lol, Frick you ARE funny!). Turns out it was a problem out on the main power pole for the street. Electric company ended up turning off the power for the whole street, as I sheepishly stood in the street and looked like the one responsible for this. Anyway, steady power was the norm after that.

Additionally, I live in the U.S. deep South, where we have violent thunderstorms like the northern regions get snowfall. No matter how advanced the power grid, when those hit, you are going to incure power outages, even if only ten seconds long and power surges. A UPS is a must around here if you like your electronics!

johnspack · Apr 2, 2015

Yep, knew that too. Figured my Silverstone would never do that. But all the sudden I was getting 11.5v on the 12v rail ect, and bam! My new xtr has perfect voltages, and is designed to run on anything from 100-250v ac.
Wish I hadn't lost my 950 and 4ghz to that. At least my es xeon is doing 3.5 at 1.2v.... takes a lot more work to get it higher, and a lot more voltage.

He Must be one of those Americans who's Dad was in the 2nd world war and was posted to the UK prior to D Day and as the civilized British use to say

"Over sexed over paid and over here"

his Dad probably did'nt get any here and had to go home to the USA

Unless he moved, Frick is Swedish I believe.

johnspack · Apr 2, 2015

It's what Frick does, how long have ppl been in this forum? I expect him to come by with his "words of wisdom"! Also part of the fun of being a member of this forum!
Still need offers on an sb-e cpu and mobo for a good price. Need to know how much I have to scrounge up over the next few weeks.... food be damned, I need computer....
