250W enough for i7-7700T + GTX 1050ti?

[KenjiUmino]

short version:

 

is a Seasonic SS-250SU enough to power i7 7700T + low profile GTX 1050ti + HDD + ODD ?

 

long version:

Spoiler

i have seen a bunch of videos on youtube where people build a fully working PC inside a butchered XBOX 360. 

makes sense considering that you can snag a dead 360 on ebay for under 10 bucks while a SFF pc case can easily cost up to ten times as much.

most people, however, used a pico PSU with external power brick and as far as i know, these can only provide around 150W or so.

most of these builds also use some AMD APU, eventually paired with a super weak GPU (like geforce GT weak).

not sufficient for a gaming capable mini PC, i think

 

so i was wondering if i could do better, using a 1U (mini ITX) form factor power supply like the Seasonic SS-250SU.

 

this will at least give me 250W to work with but power is not the only factor to keep in mind, i imagine that cooling can become an issue in this small and badly ventilated case.

from what i know, heat was the no. 1 reason why so many 1st gen 360 consoles died after all.

i am pretty much fixed on using a low profile 1050 ti as the graphics card because anything lower does not really make sense for a gaming system.

so i thought about using a 7700T CPU to keep thermals under control but also have a lot of threads.

that CPU should be able to kick the snot out of any AMD APU i have seen other people use for this xbox to pc thing. right?

I wouldn't do it. Although it may work fine (that system will probably use <200W), it's just not enough of a safety margin IMO and it'd be better to get at least 300W just to be safe.

[vodkapump]

PCPartPicker says yes, that system should not go much over 200w.

A 7700t + 1050Ti shouldn't pull much more than 100-150w.

 

 

 

 

@KenjiUmino There is NO advantage to getting a 7700t over a 7700. I'd also look towards an R5 1400 instead to save some money.

And PCPP is gonna be quoting off the OEM spec sheets, and they always state a really high power draw. Like my 980 Ti asks for  600W PSU, but I run it and my i5 no prob off a 450W one.

Do you have the power supply on hand?

 

Otherwise I would spend literally $5 more and buy a 500w corsair or EVGA power supply on sale after rebate for $15.

That wouldn't fit in the case he's planning.

i have seen 300W and even stronger mini ITX power supplies, but not from seasonic or any other brand i recognise.

that won't fit, i think 1U is as high as i can go by any means - maybe SFX but that would probably require even heavier modification

I mean, 250W would be fine as long as you're not OCing too much or adding a ton of HDDs.

you could get one of those 300w pico PSUs run by an external power brick. But they are expensive. 

that's another problem. i have not set a budget yet because i am just looking around at what is possible without unnecessary expenses.

 

the 7700T seems to be more expensive than a regular 7700 anyways.

would stepping down to i5-7600T be a big deal?

i'd loose hyper threading and the already low clock would be cut down even further by 100MHz

my plan was m.2 or mSATA SSD for boot drive and a SSHD for games

Just so you know, A standard I/O shield doesn't fit in a 1U, i'm not sure what you want to do with it but be prepared to mod a lot to fit everything.

did you read the "long version" ? i am looking for options to turn a dead xbox 360 (the white fat model) into a SFF PC

There is NO advantage to buying a 7700t over a 7700. I'd personally get an R5 1400, but if you really want to stick with Intel, then a 7700 (non-t).

i thought 35W vs 65W TDP would be the advantage here and allow me to run this system off a tiny psu in a small and badly ventilated case

 

like THIS:

 

needs to go THERE: 

 

 

that empty spot to the right might be about all i have for the PSU.

 

if i can put a ryzen 1400 in there without overloading the PSU or cooking the hardware alive because thermals, i will choose ryzen in a heartbeat

You can just downclock a 7700 yourself and get the same power consumption. But a 7700/1400 will both pull around 50w under load, which is perfectly fine for what you're looking to do.

so that is 50W for the CPU, 75W for the GPU - wich is exactly half of 250W - rest of the system gets the other half. might be a close call but could actually work

The rest of the system doesn't draw much power -- all of the other components combined (ssd, hdd, mobo, ram, and fans) should all draw around 50w total.

if thermals work out ok as well then it's a done deal 

 

after all, the 7700T is around 14 to 20 bucks more expensive than the 7700 (non T, non K) and roughly about twice the price of the R5 1400
