Whats making my PC restart without warning

[Xnitro67]

Been asking few people and its sounds more the the power supply but i dont know about the heat im using the LEET Monitor and it shows idle 80F gaming 110F(depends on what game). heres my PSU its off brand startech: http://www.startech.com/Computer-Parts/PSUs/ATX-Power-Supplies/Reliable-400-Watt-ATX12V-201-Power-Supply-with-20-and-24-pin-Connectors~ATX2POWER400 . happened on tuesday playing LoL just shutoff and restarted. its very random during games be any game really, if it is that PSU im thinking of the corsair 600w if its the heat need some tips.

80F (35C) and 110F (45C) shouldn't be a problem. If it was 80C and 110C then yeah.

That power supply is pretty crappy. Get a good one from Tier One - http://www.tomshardware.com/answers/id-1804779/power-supply-unit-tier-list.html#13224310

If your pc stays on long enough, download and run HWinfo and tell us the min and max values you get for the 12v, 5v and 3.3v voltages. If they are more than 0.2v from the target then the psu is faulty.

If its a bios hiccup then it might be worth doing a bios/cmos reset.

Give your full PC details otherwise its only the faulty PSU.

I personally think that it is indeed the power supply.

 

[Xnitro67]

wasnt sure if specs were needed :
its not a custom build
HP Pavilion p6654y
N-Alvorix-RS880-uATX (Alvorix) mobo
AMD Athlon II X4 630 @ 2.8
HyperX blu 2x4gb 1333MHz
Geforce GTX 750 1gb ddr5

i dont know how to upload pictures but everything is over 2v thats more than .2v

 

[i7Baby]

Does your pc run enough to Download and run HWInfo (32 or 64 per your OS)?

If you can then provide min and max readings for the 12v, 5v and 3.3v rails. This will give us the info to decide whether your psu is 100% OK or not.

 

[Xnitro67]

I'm not home now but I do remember even the minimum was above 2volts

 

[i7Baby]

Vcore? Should be about 1.3 max

 

[Xnitro67]

When I get home where do I put up pictures so you can see it

top and bottom on sensor

found this out on game-debate site http://www.game-debate.com/psu/index.php?ps_id=176&psu=StarTech%20ATX2POWER400%20400W#discussForm
this psu is made for dual cores not quad cores

1. CPU too hot (38C) - lower Vcore by .05V, raise cpu fan speed to just over 1000rpm

2. Power supply voltages all too low. Replace power supply with a good one. Something form Tier one if possible - http://www.tomshardware.com/answers/id-1804779/power-supply-unit-tier-list.html#13224310

For a pc running a GTX750 you need a power supply that will provide a minimum of 20A on the 12V rail and 400W in total eg Antec HCG 520M, XFX 550, Seasonic 520

Also check the voltages in the bios.Let us here know what the values are there.

 

[Xnitro67]

It's all on the pictures but I got a 600M today and the mobo has a 4pin cpu and the psu has an 8pin connector

 

[Vic 40]

That 8pin is 2x4 together,gently try to break them apart.

i dont know how to and thanks little odd but pc is back on with the corsair 600m

Good to hear it's working again with the new psu.
