240w psu enough?

[matthewletwot]

Will a 240w PSU be enough for a i5 6400 and a 1050 ti at full load (rendering stuff in blender etc)?

Dell 3650? Yes it will work.

No. It will not. Plus, it's probably a low quality unit on top of being low capacity, which makes the problem even worse. The minimum capacity power supply you would want to use for that configuration would be something in the neighborhood of 350w, and 450w would be a lot better especially if you have any plans at all to overclock the GPU card. Even so, those numbers reflect the use of a high quality power supply, not a mediocre, generic or worthless gabillion watt dumpster fire model.

Are you in need of a PSU recommendation, and if so, what kind of budget can you put together for a power supply? If you are planning to buy the entire system, what is your full budget for all needed components?

If you already have these components, you definitely need a different power supply. Even if that was a Seasonic 240w unit, which I'm sure it's not since they don't make a 240w PSU, it would not be suitable for that configuration.

No, it's not. Not even close. Not even close to close.

The slot and 6 pin take 150w together, and I assure you the rest of the system uses more than 100w, which leaves absolutely no headroom for degradation, cooling considerations, spikes or the probability that you'll be running at 100% capacity any time that card is under heavy use, which is certainly going to cause it to die, at best, in a very, very short amount of time. Hopefully, it doesn't also take your graphics card and motherboard with it since cheap OEM models like that generally come with only minimal protections.

1050 TI does not need an external 6 pin, most do not have one. Some brands do have for overclocking. The 1050 TI is designed for the 75W slot limit.


Per the article and video, they had the I7 with 1050TI pulling 150W. Take the 240W PSU and multiply by .8 for the 80% efficiency of 192W How does that not cover it?

I am running one pc an HP elite 6200 pro with a MSI 1050 TI low profile and it has a 240W psu.

Granted there are some really cheap oem that have a 25W x16 slot spec and they will not work even if they had a 450W PSU.

Actually, that's true for many of the models. Probably half of the dual fan models use a six pin connector though. Even so, most of the 1050 ti models, if you look at the manufacturer product page, specifically outline a minimum of a 300w PSU, even on models that do not require a six pin connector and including many of those that are smaller single fan models.

And those recommendations do not factor in any amount of overclocking, they do not factor in the fact that it is highly recommended to run a PSU that has about 40% more capacity than the maximum needs of the system unless you want to replace power supplies every other year, they don't factor in spikes and we know from years of card testing that all of these gaming cards can spike well beyond their specified maximums. They also definitely don't factor in the fact that with a unit that barely meets the requirements of the system you are likely going to be dealing with maximum noise levels from the PSU any time you do anything that uses the graphics card more than rendering browser pages.

It also doesn't consider the fact that there are practically NO power supplies on the market, which are ATX form factor AND of any kind of decent quality, that are below 350w. If you get a PSU below 350w, unless you specifically get one of the few models out there made by Delta or Seasonic, or a very small selection of fairly decent SFF units, chances are almost 95% likely that it's going to be a crap unit. That's just a fact.

For me, even a GPU card that costs under two hundred bucks is still something I'm going to value and want to last, and it's probably not going to with an OEM or low quality PSU in use. Bottom line, it's your money and your system, so it's up to you to use best practices to ensure your hardware is well taken care of, or not.

Will it run, I think so. But you'd really be taxing that PSU while rendering. Between power spikes and without knowing the efficiency or quality of power being delivered by that PSU, I doubt you'd have a stable system. Find at least a quality 350w. Enough to power the system without having to run at 100% to do so.

 

[Karadjgne]

Many of those 240w type units only have 9-12A on the 12v rail, which barely covers running the pc. The gpu intended is a low power unit like the older gt710-730 that'll run 20ish watts. Not the 70ish watt cards.

It'll work, as long as it's a Delta or Seasonic unit, they run higher amperage rails, but if it's a cheap knockoff, good luck.

 

[Peter Martin]

i would not recommend it at all.

 

[Darkbreeze]

Whether or not it "works", and whether it is a good idea, or is safe, or would be advisable, are worlds apart. Also, I don't see any 240w Delta or Seasonic ATX power supplies, so it's a good bet that it's some cheap OEM model that is definitely not safe. Knowing the model number would certainly be helpful. Even if it's a decent brand though, I wouldn't trust it for anything more demanding than games on Pogo.
