Hello there smart people! Today I want to ask you maybe a simple question for you, because for me it's not :d.. This is my system spec:
CPU:G4560
GPU:1050
PSU:500W
RAM:4GB 2400Mhz.
MOBO:MSI B250M Bazooka

So. Yesterday when a friend was building my pc he said that I should upgrade soon to a at least 600W because the mobo requires a bit too much power. I know that my cpu and gpu don't consume much power but I wanna just ask, can I OC my GPU and be alright ? And can you explain to me by OC my 75W gpu how much W will it eats after OC ? That's all! Thank you for your time and help! :)

Things against overclocking:

  • * Pentium G4560 has a locked multiplier
    * MSI B250M Bazooka chipset doesn't support overclocking
    ** Potentially, the PSU (see below)

** You have a 500W PSU, that in itself isn't necessarily a deal-breaker on overclocking, but can be a contributing factor to how much of an overclock, provided the CPU had an unlocked multiplier and the motherboard chipset supported overclocking.

The real concern is the quality of PSU involved. Some are pure junk, or worse: ready to take out your components and/or burn down your home. Others are perfect to deliver what they are rated for under extreme conditions. Many lie somewhere in between. Note that even without overclocking, the quality of PSU is something that...

You are right about the overclockability of the CPU, but the OP could have a POJ PSU, suitable only as a fire starter or paperweight. We don't know how good it is without more data.

I hate crap PSU's as much as the next guy. But if you have a basic system and any 500w PSU and it is working and stable, the additional draw from overclocking won't likely be an issue (no matter how poor that PSU is). For it to be an issue then the only cause would be if the PSU could not provide the additional amperage to the CPU, this is not likely to ever occur unless you have both a crap PSU and a box that is already pushing that wattage. So if in theory his CPU was overclockable, then that PSU would suffice (even if it generally sucks).

EDIT:

Okay, I see you are referring to your GPU, and overclocking it. Same thing applies about the PSU. Mind you that your overclock is limited to the max the motherboard can safely deliver, and the PCIe spec is 75W max delivery, so based on the fact that a GTX-1050 has no extra power connectors...

500W in and of itself isn't the issue. (a 500W PSU is good enough for an 180W TDP GTX-1080.) It still depends on quality of the PSU.

Good catch by shrapnel_indie. I totally missed that you were asking about a GPU.

Yes your current PSU is enough. The difference in power consumption between a stock 1050 and an overclocked one is not a large difference. You will be limited by what the PCIE socket can provide not your PSU.

I agree with you, except for the fact that there are PSUs out there that say they are 500 watt units, but when you actually test them they can only deliver 250-300 watts before blowing up. Said POJ may indeed run the current system, but any additional draw will put them over the edge. So without knowing the make and model PSU, I wouldn't want to make a blanket statement that if it works now, it should be able to handle an overclock.

Click to expand...

How much power it eats will depend on how much you overclock and the silicon lottery. You might get lucky and get a great overclock that is stable and doesn't use a lot of power, or you might get a weak overclock that requires a lot of power. It all depends on the silicon that makes up the GTX 1050 GPU core.

Given that the factory overclocked ones consume less than 50watts the odds of him needing anywhere close to 75w seems pretty unlikely. I think he'll be fine.

Yeah, more than likely he'll be fine on the 75W limit. I was of course referring in a more relative and generic space since it applies to any GPU (or CPU for that matter.)

Thank you all so much! Really appreciate your time to help me out :) For now I will stick with this one and will OC and in the near future I will buy probably a EVGA 600W or smth like that. Agian thanks!
