Quality 450Watt PSU with GTX 770 and i5-4670K, Possible?

Jish · Jul 3, 2013

Yes I know there is a solved thread on this, but my question is more precise and deals with exact parts.

I was looking to make a mini gaming computer. My ideal build would be

Case: Mini-FT03
http://www.newegg.com/Product/Product.aspx?Item=N82E16811163176

GPU: Galaxy 770
http://www.newegg.com/Product/Product.aspx?Item=N82E16814162135

CPU: i5-4670
http://www.newegg.com/Product/Product.aspx?Item=N82E16819116899

PSU: Silverstone Gold Rated 450 Watt Full Modular
http://www.newegg.com/Product/Product.aspx?Item=N82E16817256084

Mobo: Any ITX one really, there are only 4 1150 Mini-Itx's on newegg anyway.

Monitor:Maybe two, but gaming will only ever occur on one. 1080p Monitor.

So do you think that PSU above will be able to power the CPU+PSU+Everything Else when running games on high settings?

As long as you don't overclock too much, it's plenty.

It's certainly possible, but I really won't go for anything lower than a 550w. Remember if you limit your PSU, you will also limit the overcloking potential of the 4670K and the GTX 770. This kinds of defeats the purpose of getting unlocked parts. Hope this helps!

It's a little tight for my taste, although it will probably work, I would try to get a tad bit more powerful PSU.

The monitors(S) make no difference as they are not powered by the computers PSU. As long as you don't add any more disk drives, or do any kind of overclocking you should be ok. Nvidia recommends at least a 600w PSU. I would rather have too big a PSU rather than too small. Remember, the PSU is the heart of your system, without it NOTHING works. A PSU is the only component in your build that can destroy ALL the other components in your build if it fails. Never skimp on a PSU, it is false economy!

As long as you do n't overclock AT ALL its, barely enough:

Add in capacitor aging and you're asking for trouble a few years down the line.

How about the Antec BP550; it's a very nifty little power supply which provides 550W of power and 80 PLUS certification and is made by Antec (quality brand) and is Modular. For $64.99, it's quite a steal though it's much better if the price was lower. It should handle mild overclock with your CPU and GPU. The best case scenario is get a 650W PSU. This way, you can handle any single GPU and CPU overclock with room to spare.

PSU calculators are unreliable. It's PLENTY with no OC. With OC, it's doable but the margin for error gets a bit small.

Sakkura · Jul 3, 2013

basch99 :

This is just plain bad advice. The Antec BP550 has 32A on the 12V rail. The Silverstone ST45SF-G 450W has 37A on the 12V rail. The 450W PSU is MORE powerful where it counts than the 550W PSU.

basch99 · Jul 3, 2013

hmmm okay my bad didn't see that there. I ran my Antec VP450 with a GTX 670 and it worked fine. Lemme see how about the popular Corsair CX600 for just 5 bucks more? It's solid enough in my opinion as I own one CX600 myself.

Jish · Jul 3, 2013

The only issue I have with other PSU's is the size restraint of the FT03-Mini. Only allows for SFX power supplies

Sakkura · Jul 3, 2013

Just stick to overclocking the CPU and there's no need for a different PSU. There's not much performance to be gained from overclocking the GTX 770 anyway.

basch99 · Jul 3, 2013

Oh my bad, A SFX PSU? holy man, this is hard. There are like no PSUs out there for this form factor. You do you that your silverstone case IS designed for HTPC use right? I don't think I can help unless you're willing to look at other brands of SFX Psu.

clarkjd · Jul 3, 2013

Newegg has this 600W one:

but I know nothing about the reliability of this manufacturer.

Sakkura · Jul 3, 2013

clarkjd :

Athena Power is generally not good.

Also, each 12V rail only has 8A, which is very low. They add up to 32A, which is still less than what the Silverstone PSU has; and you usually can't load all 12V rails to their individual capacities at the same time.

If you're still checking this thread, Jish a suggestion:
Aim for a slightly lower card, the GTX760 uses less power and is more than capable of running 1080 res, it's about on par with my HD7950 and that's no slouch at gaming, even stock

.

Sakkura · Jul 3, 2013

coozie7 :

Not necessary. A GTX 770 at stock will be fine, and performs quite well.

Skynner · Sep 11, 2013

It will probably work and be ok...but..if your going to buy a 4 or 500 Dollar Graphics Card you should be able to have enough bucks to invest in a decent PSU..I Personally would suggest the Ultra 650 80+ Bronz..Skimping on a PSU is just not a good idea.

isaiah davis · Feb 13, 2014

Skynner :

Too many people did not read the thread, he can only use a sfx sized psu, this is not a money issue. Though in a normal build i would accept the 650 watt recommendation lol, 450w is scary.
